1905 movie network news On October 29th, the animated film held its premiere conference in Beijing. As the first animated film co-produced by China and Germany, the film will be released in China on November 8th. On the day of the event, Lei Yuhan, Minister of the German Embassy in China, Fu Ruoqing, Vice Chairman and General Manager of China Film Co., Ltd. and other guests attended.


Reinhard Klose, Director of Pet League


Pet League tells the story that stray dog Roger and abandoned robot Bob lead abandoned pets to defeat Frankstone, the ruler of the future city who tries to replace human beings with robots, and restore the peace of the future city. Lei Yuhan, Minister of the German Embassy in China, expressed his wishes for the release of the film and hoped that the co-production projects between China and Germany would become more colorful in the future.


Fu Ruoqing said in his speech that "Pet Alliance" is an important achievement of animation literature and art exchanges between China and Germany, and he hoped that the film would be loved by the audience after its release. According to Song Weiwei, executive deputy general manager of China Film Animation Industry Co., Ltd., the film producer, Pet Alliance is initiated and controlled by the Chinese side, aiming at international distribution. It is expected to be sold by the end of December this year and will be released in many countries and regions from January to May next year.

As an international co-production project, director Reinhard Klose mentioned in an interview that his creative space is very large, and the advice given by his partner in China is to tell the story naturally according to his own ideas, which makes him feel particularly happy to have such cooperation. Speaking of the animated characters who have devoted themselves to hard work, the director said that they are equally fond of each character, and even the villains in the contiguous film have a cute feeling.


Pet League, as a creative animation by China, is directed by a German. Klose said that the ultimate goal of this film is the international market. Compared with its previous work, the German flavor of Pet League is not so strong, but it incorporates the hidden lines of robots and artificial intelligence that I am interested in: "Artificial intelligence is a very important clue in the movie, and of course there are environmental problems. We chose this expression when we wrote the story script. "

Producer of Pet Alliance Song Weiwei


According to reports, "Pet Alliance" takes five years from the project development, and it takes three years from the start of shooting. In an exclusive interview, director Klose said that he was shocked by the rapid progress of the project: "The number of staff involved in this film is three times that of a European animated film. For me, it is really incredible that I need to coordinate the staff, overcome the barriers between cultures, and be able to make this film within three years. But time is not important. What is important is that the staff of this film put all their energy into it. "


The staff of Pet Alliance are all over the world, and in China, there are also staff from Shenyang, Suzhou and Beijing. Director Klose said that this is really a great challenge for him. At the busiest time, I may have to dock 20 teams. China Film Co., Ltd. and China Film Animation have also given considerable support to the film, from the 3D modeling of the film to the design of the scene, they all have their input.


In addition to this animated film co-produced by China and Germany, China Film Animation also co-produced Hailong with New Zealand on the theme of the Maritime Silk Road. With Malaysia, he co-produced the Shadow King and other works that incorporate the elements of shadow play, and will meet the audience one by one in the future. Pet League will be officially released on November 8th.


Data Perspective on Sino-US Trade Friction: Analysis of the Latest List

  What impact will the "301" list put forward by the United States twice have? It is worth further analysis from the data. The full text is about 6600 words.

  Michael Kinsley, a columnist in Washington Post, once imagined the following scenario when introducing the game theory of Thomas Schelling, a great game theory scholar and Nobel laureate in economics:

  "You are standing on the edge of a cliff, with chains around your ankles, and your opponent is locked at the other end of the chain. As long as your opponent gives up, you will be released and win a big prize. Here’s the thing: your only means is to threaten to push him off the cliff — — But that means you’ll be shattered, too. So, how can you persuade your opponent to give in? "

  Schelling’s answer is: "You start dancing and get closer and closer to the edge of the cliff. In this way, you don’t need to convince your opponent that you are crazy — — Take him and yourself out of the abyss. All you need to do is convince your opponent that you are more willing to take the risk of falling off the cliff out of control than he is. If you can do this, you will win. "

  Schelling’s thoughts have influenced a generation’s understanding of the Cold War between the United States and the Soviet Union. Fortunately, or unfortunately, after the end of the Cold War and the development of globalization for nearly 30 years, we may have to turn back to the old paper pile to find the wisdom of our predecessors.

  The reality is that after at least two rounds of negotiations and a "consensus" were reached between China and the United States, President Trump once again opened the trigger insurance for the Sino-US trade war. On May 29th, Trump announced that he would continue to seek to impose punitive tariffs on China’s imports. On June 15th, another boot that the market has been waiting for fell, and the Office of the US Trade Representative published a list of goods worth about $50 billion for China. Compared with the preliminary list published on April 6, the new list has undergone two changes: First, 818 of the 1,333 8-digit HS-coded commodities listed in the preliminary list have been retained. As the first batch of commodities in the final list, they have already faced 25% additional tariffs from the US Customs on July 6, and this batch of commodities is worth about $34 billion. Second, a second batch of goods has been added to the final list, including 284 goods worth about $16 billion, which will be taxed after the hearing procedure.

  The President of the United States, who is well versed in "the art of trading", did not give the market a breathing space. On July 10th, the President announced that he planned to impose a 10% tariff on a new batch of China goods worth $200 billion, and held a hearing in late August. Another boot hangs high, waiting to land … …

  Almost at the same time, the Trump administration also announced a tax on steel and aluminum products exported to the United States by the European Union, Canada and Mexico. Trump’s capricious and all-round "fighting style" has left his opponents (and perhaps some of his ministers) at a loss. This repeated change (let’s call it "Trump uncertainty") may reflect his firm belief in fulfilling his promise to voters, or perhaps the game between the two forces of hawks and doves in his cabinet. We don’t know. But one thing is certain: the Trump administration’s eyes have always been fixed on containing the future potential of China’s economic development. "Made in China 2025", which was issued by the State Council in 2015 and the China version of "Industry 4.0" plan, finally became a household name with the Sino-US trade dispute in 2018.

  Then, what kind of impact will the "301" list put forward by the United States twice have? It is worth further analysis from the data.

  Analysis of tax list

  First of all, considering the "232" list of steel and aluminum products in March, the "301" list of $50 billion imported goods in June, and the "301" list of $200 billion added in July, at present, the scope of US taxation on goods from China is close to 50% of all its imports. We use the import data published by the US Bureau of Statistics in 2017, so the actual amount involved is slightly different from the target amount announced by the US government. Interestingly, the list in July involved goods worth nearly $200 billion, covering 6,031 goods with HS8-digit codes, while the remaining goods that have not yet entered any list, worth nearly $260 billion, accounting for more than half of the US imports from China, only contained 3,313 goods with HS8-digit codes. In other words, there are real "big guys" who are not involved in the "trade war". Judging from the share of these goods in the total imports of similar goods in the United States (column [6] of Table 1), it can also be clearly seen that with the spread of the "trade war", China goods listed in the tax list in July accounted for 23.2% of the total imports of similar goods in the United States, far exceeding the two lists in June (7.7% and 14.7% respectively), while these goods that have not been listed account for 38% of the imports of similar goods in the United States. It can be said,Strategists who want to know what is the "pain point" of the United States and what is the real competitiveness of China manufacturing may wish to study these products that are not on the list.

  Note: Data are from the United States Bureau of Statistics; 6— There are 51 items, 11 items and 1,030 products in the three lists in July, and the value of US imports from China in 2017 is zero. One product, aluminum products, is listed on the "232" list of steel and aluminum and the "301" list in July.

  From the bar chart in Figure 1, we can see the distribution of different listed goods in different industries more intuitively. According to the definition of customs, we divide all commodities into 22 categories, from animal and plant products to works of art and unclassified products. According to the value of the "301" list in June, figure 1 is obtained from the highest to the bottom. Obviously, on the list in June, mechanical and electrical products, optical, medical devices, transportation equipment and other industrial intermediates and parts are the most concerned objects. By July, on the list of 200 billion yuan, electromechanical still topped the list. The proportion of miscellaneous products, especially some direct consumer goods (such as games, furniture, chairs, lamps and lighting devices, etc.) has increased significantly. More importantly, the product areas covered by the July list have also increased significantly. Among the 22 industry categories, the June list only involves 8 industries, while the July list has not been spared except for weapons and ammunition and unclassified goods. At present, products that have not been listed on the tax list are mainly concentrated in industries such as electromechanical, textile, miscellaneous products, shoes and hats.

  Note: The above 8-digit commodities of HS do not include 330 commodities (except 76169951) worth $2.8 billion in the list of steel and aluminum 232. The list taxes steel products by 25% and aluminum products by 10%.

  Data source: The author collates the data from the United States Bureau of Statistics.

  So to what extent will the taxation of these goods affect the domestic economy of the United States? A simple judgment method is: If there are many competitors for a commodity and the market share of China exporters is low, then the tax on the product may have little impact, because the buyer can easily find a substitute. Therefore, in Figure 2 to Figure 4, we classify the products listed in June, July and not listed in the list according to the industry categories defined by China Customs, and calculate the proportion of the value of US imports from China in the total imports of the same category, so as to reflect the dependence of the United States on China’s exports. It can be seen that among the eight categories of goods affected by the list in June, base metal products account for the highest import share, but only 28.2%. Followed by ceramic glass products and electromechanical products (17.2% and 16% respectively). By contrast, for the July list, China is the main source of imports for the United States in a considerable variety of products. Shoes and hats exported from China account for 73.8% of the total import value of such products in the United States, and the import shares of miscellaneous products and fur products are as high as 65.6% and 60.4%.

  In this $260 billion commodity that is not listed in any list, China accounts for an even larger proportion. For example, vegetation products account for 75%, the remaining mechanical and electrical equipment accounts for 73%, and shoes and hats account for 72%. There are eight major categories of products, and the import proportion of China in the United States exceeds 50%.

  Data source: The author collates the data from the United States Bureau of Statistics.

  The use of goods exported from China to the United States is also very important. According to the BEC classification standard of the United Nations Statistics Department, we classify commodities into four categories according to their final use: consumer goods, capital goods, intermediate products and other four categories. Using the value data of goods imported by the United States from China in 2017, Figure 5 compares the total import value of goods listed in June, listed in July and not listed in each category. In June, the products targeted by the two lists were mainly capital goods and intermediate goods (accounting for 94.4% and 97.6% respectively). The import value of capital goods in List 1 was comparable to that of intermediate goods, both of which were more than 15 billion US dollars, while the value of intermediate goods in List 2 was twice that of capital goods, accounting for 65.2% of the total import value of List 2. The July list covers all categories, among which the value of intermediate products is as high as 94.7 billion US dollars, accounting for the highest proportion (48.1%); Capital goods ranked second, with a total import value of US$ 57.5 billion, accounting for 29.2% of the total import value in the list. What is important is that the share of consumer goods in each list has increased significantly. In June, the consumer goods involved in the two lists were worth $163 million and $339 million respectively, accounting for only 0.5% and 2.4% of the total value of their respective lists; In July, consumer goods accounted for 22.7% of the list. In 2017, the import value totaled 44.8 billion US dollars, which was more than 89 times the sum of the value of consumer goods in the two lists in June. The goods not nominated in the list mainly belong to capital goods and consumer goods, worth $120.7 billion and $98.3 billion respectively.It accounts for 46.6% and 37.9% of the import value of goods not on the list. Another $34 billion of intermediate products have not been affected by the tax list. It can be said that with the intensification of the "trade war", American consumers will inevitably be directly affected by rising prices. The manufacturing enterprises in the United States will inevitably face the pressure of rising parts costs, leading to a decline in competitiveness, which may further reduce American exports.

  Further, in Table 2, we list the top 10 products (HS4-digit codes) imported by the United States from China in 2017, and count the amount of these 10 products affected by each list and the number of HS8-digit products respectively. Obviously, these 10 products that the United States needs most from China are not the key targets of the US tax list. These products were basically spared in the two lists in June, while the value of products taxed by the list in July for the first-ranked wireless communication equipment (such as mobile phones) was $23.6 billion, accounting for 32.9% of the total imports of such products. Automatic data processing equipment (computers) and spare parts products ranked second and third are the few products in the top 10 categories that are taxed by the June list, but they only account for 2.9% and 1.4% of the imports of their respective HS4 products. However, the list in July increased the tax value of these two kinds of products, and the import proportion of taxed products rose to 15.6% and 98.6%. Interestingly, all computer parts and components were included in the tax list, but did it lead exporters to further transfer processing and assembly to China and export finished computers? In addition, imported furniture ranked sixth and auto parts, lighting devices and suitcases and handbags ranked eighth to tenth were all wiped out in the July list.

  Furthermore, from the point of view of HS8-digit products, Table 3 summarizes the distribution of market share of listed products in the United States. According to the import data of the United States in 2017, we calculated the share of HS8 products imported by the United States from China to similar products imported by the United States from the world. It is not difficult to find that the market share of China commodities targeted by the steel and aluminum 232 list and the two lists in June is mainly concentrated in 0-mdash; 25% and 25%— In the 50% range. In July, however, the list gradually shifted its target to commodities with larger market share, and the scope and intensity of the spread were significantly increased. The market share is at 50%— 75% and 75%— For goods within the range of 100%, the cumulative import amount taxed by the July list is 40.8% and 24.5% of the total amount of the July list respectively. Among the commodities that have not been affected by the list, the market share of commodities worth $163.3 billion exceeds 75%, accounting for 63% of the total value without tariffs.

  Taxation and "Optimal Tariff": A Theoretical Explanation

  From these analyses, we can know that if the scope of taxation in the United States is extended to its July list, or even further extended to products that are not listed, it will inevitably hit those products that China imports in the United States, including a large number of consumer goods and a wide range of industrial intermediates. This will not only hit China’s export enterprises, but also hurt the welfare of American consumers. In this sense, tariffs are essentially "taxes levied on domestic consumers" (Dartmouth College economist Douglas Irwin).

  What is worrying is that "Trump uncertainty" will bring great troubles to the efficient global value chain, and force entrepreneurs to consider political factors while considering the global production layout. Even if we don’t consider the effects that will take some time to show, in the short term, tariffs will immediately increase the cost of exporters. These extra costs will force exporters in China to lower the export price and partially "share" the price increase faced by consumers (in the case of prevailing intermediate trade, consumers here are often producers in downstream industries). The part that cannot be fully shared will be "transmitted" to consumers, forming the after-tax import price.

  Obviously, the stronger the downstream buyers (consumers), the more they can force the upstream sellers (exporters) to make concessions and lower some export prices. Consumers like you and me can’t change the market price by buying more or less. In economic terms, we are faced with infinite supply "elasticity", or the supply curve is horizontal. But big buyers are different. For example, a big supermarket like Wal-Mart can completely influence the price through the purchase volume. At this time, the supply curve is inclined upward. It is also true to further expand the analysis to the national perspective. Small countries can’t influence the world price, but they are the recipients of the price, while big countries are faced with an upward supply curve and can influence the world price. Obviously, the United States is a real big country and the largest market in the world. Therefore, it can press exporters to lower prices by imposing import tariffs. In the theory of international trade, the ratio of export price to import price is called "terms of trade", which can be improved by imposing tariffs to force the import price to decrease.

  Therefore, for a big country, increasing tariffs will certainly lead to the loss of consumer welfare — — Because the after-tax price faced by consumers is still rising, from the welfare point of view, the improvement of terms of trade means that there is such a positive "optimal" tariff, which maximizes the net income of big countries. This may be one reason why Trump dares to wave the "tariff" stick. Specific to each product, its "optimal" tariff rate depends on the supply elasticity of the commodity (exporter). For goods with less elasticity of supply, the response to tariffs is more intense, the proportion of export price decline is more, and the optimal tariff is bigger. Therefore, international economists have abstracted a very simple formula to determine the optimal tariffs of different commodities in the case of big countries, namely: tariff rate = 1/export supply elasticity.

  Further analysis of tariffs

  Based on this, we summarize the original tariff level of each listed commodity in Table 4. Generally speaking, American import tariffs remain at a fairly low level. The tariff of most imported goods is less than 5%, while the tariff of quite a few goods is zero. For example, in June, 375 of the commodities involved in List 1 had no import duties, accounting for 60.9% of the list value. This proportion is 48.6% in June list 2 and 54.2% in July list. In the two lists in June, only five goods with the original tariff of HS8 were higher than 10%, and the sum of import values was less than $05 million, while in the list in July, there were 329 goods with the original tariff higher than 10% and the total import value was $3.228 billion.

  Data source: According to the data compiled by the US Bureau of Statistics, some commodity tariff data are missing.

  Figure 6 compares the import tariffs of the United States with those of China. We weighted the import tariffs of China and the United States according to the import value according to 22 categories of industries, and got Figure 2. Each point in the graph represents the import tariffs of the United States (horizontal axis) and China (vertical axis). Most of the points are above the 45-degree line, which shows that the tariff structure between China and the United States does have the situation that the US tariff is lower and the Chinese tariff is higher. This goes without saying, but considering the current tariff structure of the United States, it began in 1934 that President Roosevelt took the initiative to lower tariffs and sought other countries to lower trade barriers in order to promote American exports. As the country that has benefited the most from international trade, the United States led the signing of the General Agreement on Tariffs and Trade (GATT, the predecessor of WTO), which advocated free trade. China, on the other hand, only started the negotiations on joining the WTO in the mid-1990s, and reduced the import tariff from an average of 43% in 1992 to around 9.8% in 2007. In addition, in Figure 6, we have not considered the import of processing trade that is common in China, which accounts for about 13% of China’s imports from the United States, and it is exempted from customs duties or refunded in the import process.

  According to the optimal tariff theory, we re-estimate the optimal tariff of American goods imported from China by using the elastic estimation data provided by Anson Soderbery, an economist at Purdue University. HS8-bit commodities with missing elasticity data are replaced by the average elasticity of the commodities at HS6, HS4 and HS2. Table 5 summarizes the relationship and proportion of the actual original tariff, new tariff and optimal tariff of each imported commodity. Obviously, after the tariffs were added to the three lists, the new tariffs of most commodities exceeded the optimal tariffs. In June, 71% and 48% of goods were listed in the list 1 and July, respectively, and their original tariffs were lower than the highest tariffs. After adding 25% and 10% tariffs respectively, the proportion dropped to 43% and 26%. Among the commodities targeted in Listing 2 in June, 57% of the commodities have their original import tariffs exceeding the optimal tariffs. After the tariff of 25% is added, the proportion of goods exceeding the optimal tariff will be as high as 75%.

  Data source: The author estimates according to the elastic data provided by Soderbery (2018JIE). Some commodity tariff data are missing.

  Game dilemma of optimal tariff

  Since there is such an "optimal" tariff for a big country, the improvement of terms of trade brought by tariff collection offsets or even exceeds the loss of consumer welfare, why do economists actively advocate tariff reduction? This is because in this world, not only a big country, even a small country, often has the ability to influence world prices in certain industries or commodities, not to mention domestic political considerations and national sentiments, and it will not allow a country to impose tariffs on the other side without taking any countermeasures. Imagine, if there are only two countries in the world, and they all give each other a tariff attack on a specific industry according to the theory of optimal tariff, both sides have improved their terms of trade in the industry that raised import tariffs, and suffered losses in the export industry. In most cases, the result is that both sides are in a dilemma: both sides get benefits by increasing tariffs to attack their opponents, but if both sides take measures to reduce tariffs, both sides can benefit; However, the difficulty is that neither side can or will unilaterally declare a truce — — Because it means greater losses. In this way, the two countries have fallen into the common "prisoner’s dilemma" in game theory. In this game, each side acts according to the optimal strategy under given conditions, but the final outcome is "lose-lose".

  If every country in the world acts unilaterally according to the optimal tariff strategy, or retaliates against the tax payers, then we will go back to the Great Depression in the 1930s, due to the introduction of Smoot — The Smoot-Hawley Tariff Act pushed the average import tariff of the United States from 40% to nearly 60%. In just two years, the import and export of the United States fell by 40% at the same time. The world trading system has suffered a major blow.

  Is there a solution to jump out of the "prisoner’s dilemma" of building trade barriers? History has long given us the answer. In the process of European reconstruction after World War II, Americans led the signing of the General Agreement on Tariffs and Trade (GATT) in 1948, and through an external agreement, they forced the signatory countries to reduce or exempt tariffs from each other, thus jumping out of the "prisoner’s dilemma". GATT, as well as the World Trade Organization (WTO), which replaces GATT, stipulates that when a country reduces or exempts tariffs on one GATT member, it must also undertake the same duty of reducing or exempting tariffs on all other GATT members. This is the most important principle of "Most Favoured Nation" in GATT. This principle also protects many small countries that do not have the negotiating ability to share the welfare improvement brought about by trade liberalization to the greatest extent.

  Ironically, today, with the development of globalization far exceeding the 1950s, the main founders and promoters of the international multilateral economic and trade system are working to challenge or even destroy this system, instead of improving and perfecting it. Carla Hills, an American trade representative in the 1990s, once said, "Without WTO, the world would have only the law of the jungle". I hope that the leaders of China and the United States, and even the world, will have enough courage and wisdom to lead us away from that scene.

Chengdu, the first pilot market procurement trade mode in western China, started.

On March 28th, the first goods exported by market procurement in Chengdu were cleared by Qingbaijiang Customs at Chengdu Customs. The goods, valued at $148,000, will be exported to Poland on the China Europe train (Chengdu).

In September 2018, Chengdu International Trade City was approved as the fourth batch of pilot markets for market procurement and trade methods in China. This is the first pilot export trade after approval. The main commodities are men’s cotton-padded jacket and women’s leisure suits.

The trade mode of market procurement refers to the trade mode in which qualified business operators purchase goods in the market gathering area recognized by the national commerce authorities and other departments, and the value of goods with a single ticket declaration form is less than 150,000 US dollars (including 150,000 US dollars), and the export goods are cleared at the place of purchase. Fourteen cities in four batches were approved for pilot projects. jinniu district, Chengdu, where Chengdu International Trade City is located, is the first and only pilot project in the western region.

According to the relevant person in charge of Chengdu Customs, the goods purchased in the market have the characteristics of "single small goods and miscellaneous goods". In this way, small and micro businesses can also participate in foreign trade. Zhou Lizhi, chief economist of Chengdu Municipal Bureau of Commerce, said that the pilot of market procurement trade mode also has five policy advantages: implementing VAT exemption, facilitating customs clearance, innovating exchange system, improving supervision ability and lowering entry threshold.

The relevant person in charge of Chengdu said that Chengdu will take the pilot market procurement trade mode as an opportunity to strengthen trade exchanges with countries and regions along the "Belt and Road" and continuously expand the pan-Eurasian international market.(Reporter   Zhang Minghai)

Look up to U7, equipped with "Eye of God" advanced intelligent driving system.

In the automobile market, price strategy is always a sensitive and key topic. Even if the price of a new car is higher, if no consumer is willing to pay for it, the higher price can only be "valuable without market". On the contrary, if we blindly pursue low prices, although the sales volume has gone up, for most car companies, it is just "losing money to earn money."

Recently, luxury brands such as BMW, Mercedes-Benz and Audi have resisted the "price war" one after another. Because of the rise of domestic independent brands, consumers have begun to prefer domestically produced cars with high cost performance, especially those with rich self-owned brands. In sharp contrast, BYD’s performance in the domestic market is particularly eye-catching.

With its strong brand influence and excellent product performance, BYD has achieved good sales results in the market. Taking advantage of the trend, BYD launched a million-level high-end brand-Looking Up. Although the price is high, the popularity of looking up to the brand is still high, especially its subsidiaries, which attracts much attention. Looking up to U7 is not only excellent in performance, but also equipped with "black technology" with four wheels rotating in situ, which makes it unique in the market.

Looking up at U7, it continues the family-style design concept in appearance design, and its front face shape inherits the characteristics. The flat front adopts coupe shape, and the exaggerated C-shape and headlight design on both sides, together with the through-hole opening and honeycomb mesh, make the front face of the whole vehicle look extremely aggressive. The side design takes both practicality and aesthetics into consideration. The ground clearance is slightly higher than that of looking up at U9. The design elements such as smooth back-sliding lines, chrome-plated window side strips, double waistlines, hidden door handles and frameless doors make looking up at U7 look fashionable and avant-garde.

In the aspect of rear design, looking up at U7 adopts a penetrating LED taillight group and a two-stage design with red and white contrast decoration, which is reminiscent of Lincoln car. In terms of size, the length, width and height of U7 are 5265mm, 1998mm and 1517mm respectively, and the wheelbase is 3160mm, which is larger than Paramera, and the interior space is more spacious.

In terms of interior, looking up at the design of U7, it is equipped with an embedded vertical curved central control panel, a full LCD instrument panel, and the entertainment screens of the co-pilots on both sides, creating a strong sense of science and technology. In addition, Wangwang U7 is equipped with dual NVIDIA Orin-X chips, three ultra-long-range laser radars and BYD’s "Eye of the Gods" advanced intelligent driving system, covering NOA to high-speed, elevated and urban areas.

In terms of power, Wangwang U7 is built on an 800V high-voltage platform, equipped with four-wheel independent torque vector control and four-motor system. The maximum power of each motor is 326 horsepower, the total power reaches 1306 horsepower, the peak torque is 1584Nm, and the acceleration of 100 kilometers takes only 2.9 seconds. Looking up at U7, it is also equipped with a battery pack of 135.5kWh, and the cruising range under CLTC conditions is 720km and 800km respectively.

Since its inception, Wangwang series has won the attention of a large number of consumers with its luxurious interior and rich configuration. Looking up to U7, it creates a luxurious feeling in the interior and visually, and the release of Yunqi -Z is the icing on the cake. It is estimated that the starting price of looking up to U7 will be around 700,000, which is more cost-effective than looking up to U9. So, in the face of looking up to U7 so well, will you consider the choice?

China Scientific Research Team: New Technology Makes Carbon Dioxide High-value "Baby"

  Take the "life gate" in your own hands.

  When it comes to carbon dioxide (CO2), people generally think that it is like waste wood, which is not only useless, but also one of the chief culprits of destroying the climate and causing global warming. So far, researchers have thought of many ways to deal with it, such as imprisoning it (curing and sealing it) and driving it into a water dungeon (drilling into the seabed). However, in the eyes of Zhang Xiangping, a researcher at the Institute of Process Engineering of China Academy of Sciences, CO2 is a good raw material, which is cheap and easy to obtain. For more than ten years, her ionic liquid team, under the leadership of Academician Zhang Suojiang, has been pondering how to efficiently convert and utilize CO2 and turn it into treasure.

  Deal with stubborn guys and send activists as "lobbyists"

  CO2 utilization is a major global strategic issue. In June 2016, the EU launched a plan to take CO2 utilization as a major research direction; Japan has formulated a road map for CO2 utilization planning; China’s National Development and Reform Commission and Energy Bureau listed it as a key task in the Action Plan. However, the activation and transformation of CO2 molecules has become one of the internationally recognized scientific problems due to the problems of difficult activation, complex reaction path and low product selectivity.

  "CO2 is a common compound in the air, and it is not easy to transform and utilize it. As we know, CO2 molecule is made up of two oxygen atoms and a carbon atom connected by a solid double bond, if you want to ‘ Knock ’ It is quite difficult to open the carbon-oxygen double bond closely linked between them and reduce it to oxygen and carbon. " Zhang Xiangping said in an interview with the Science and Technology Daily reporter.

  Zhang Xiangping further explained that direct bond-breaking activation of CO2 requires high temperature and high pressure, but if we can find other active molecules to be lobbyists, such as epoxy compounds, we can induce the activation of CO2 and make its transformation easier. In addition, it is necessary to add a "medium", that is, a suitable catalyst, to promote the efficient conversion of CO2.

  In the past ten years, after many experiments, the research team has gradually found an effective "cadre" who will live up to its mission — — The ionic liquid catalyst with multiple active sites can not only activate the double bond of CO2, but also make the ethylene oxide (EO) that reacts with it become active and open the ring more easily, so that CO2 and EO can react together to synthesize ethylene carbonate, an important chemical raw material.

  Zhang Xiangping pointed out that the team successfully prepared the immobilized ionic liquid catalyst through further chemical chain loading, which avoided the problems of easy loss and deactivation of homogeneous catalyst, difficult catalyst recovery, high energy consumption and impact on product quality.

  Coup after coup, enhancing value for efficient use.

  Efficient catalyst has been developed, and a matching reactor is needed to provide a suitable place for the reaction.

  Zhang Xiangping said: "Compliance response — Flow — According to the law of transfer and coupling, the team optimized the internal components of the reactor, realized the uniform distribution of the flow field/temperature field, and innovatively developed a 10,000-ton ionic liquid gas-liquid-solid three-phase tubular reactor, and the heat released quickly during the reaction can be discharged from the system as soon as possible, so that the reactor does not overheat and realizes safe operation. "

  On this basis, the research team adopted alcoholysis reaction — The coupling process strengthening technology of pressure swing azeotropic distillation can realize the optimal integration of the whole system heat network, greatly reduce energy consumption, significantly improve economy and reduce equipment investment.

  "In terms of technology, it is necessary to design a whole process to connect the whole reaction and separation process in order to get the final qualified product from raw materials." Zhang Xiangping told reporters, "We have optimized the integration of material and energy in the whole process, and greatly improved energy consumption, efficiency, economy and product quality to meet the needs of enterprises and markets."

  According to reports, with the support of the national key R&D plan "Clean and Efficient Utilization of Coal and New Energy Saving Technology", since May 2018, the project "New Technology for Efficient Synthesis of Important Chemicals by CO2" led by the Institute of Process Engineering of Chinese Academy of Sciences has designed and synthesized a functional ionic liquid catalyst with multiple active sites in the CO2 carbonylation reaction, realizing efficient conversion of CO2 under mild conditions. At the same time, a carbonylation catalyst meeting industrial needs has been prepared and a continuous reaction device has been built. Aiming at the alcoholysis reaction of vinyl carbonate, a catalyst with high activity and low cost was developed, a 10-ton/year alcoholysis continuous device was built, and a 10,000-ton industrial test device was established.

  Open up a new path to synthesize multiple important chemicals

  The technology of CO2 capture, utilization and storage (CCUS) is one of the main ways to realize low-carbon emission of coal in China, and the high-value utilization of the collected CO2 can not only reduce carbon emission and alleviate the greenhouse effect, but also produce significant social and economic value.

  After years of unremitting efforts, through the original innovation of catalyst, the optimization of reactor structure and the integrated innovation of the system, the ionic liquid team of Institute of Process Engineering of Chinese Academy of Sciences has developed a new route of synthesizing ethylene carbonate from CO2 and high-energy material ethylene oxide, and then producing dimethyl carbonate and ethylene glycol by alcoholysis respectively, forming a new all-atom utilization technology of mild conversion of CO2.

  Just like turning the stone into gold, products produced by CO2 are all high-value "treasures", which have a wide range of application fields and considerable market prospects, but there are problems such as poor economic benefits after being used before.

  Zhang Xiangping said that among diversified products, dimethyl carbonate is mainly used to synthesize important organic chemicals, which is known as the "new cornerstone" of green chemistry in the 21st century. It can be widely used in organic synthesis reactions such as carbonylation, methylation, methoxylation, carbonyl methylation, polycarbonates, etc. In recent years, with the rapid development of power lithium batteries, polycarbonates and other related industries, the demand for dimethyl carbonate continues to grow rapidly, and the demand in China is expected to be 4 million tons in 2020. Ethylene glycol is a raw material for the synthesis of polyester fiber and resin. China’s annual demand is more than 14 million tons, and its dependence on foreign countries is more than 60%.

  According to the insiders, compared with the reaction route of direct conversion of CO2 into synthetic chemicals, this technology has obvious advantages such as mild reaction conditions, good atomic economy and broad industrialization prospects. The implementation of the project will help China seize the international commanding heights of CO2 utilization technology, solve and break through the bottleneck problem of clean and efficient utilization of coal in China, and open up a new path for high-value utilization of CO2, which has important strategic significance.

In the third season, the lineup of iQiyi’s "Meng Detective Detective Case" officially announced "Entertaining the Living" to create the first "Happy Variety" in the whole network.

The first IP immersive reasoning reality show "Meng Detective Detective Case" produced by iQiyi finally ushered in the return of the third season in the audience’s expectation. On April 17th, the official guest lineup of Meng Detective 3: two old players, Z.TAO and Sun Honglei, returned with surprise, and five new players, Ning Jing, Naza, Qian Sun, Nana and Xu Zhisheng, joined (in alphabetical order). The 3.0 version of Meng Detective Family assembled seven "entertaining the living", and returned to the IP world of explosive movies and TV once again, and started an adventure and upgrade investigation tour with the audience to gain a happy comprehensive experience.

The most special official announcement method in the history of seven guests online tucao program group attracted onlookers.

It’s really a program that makes people love (hate) to death. It’s a program that doesn’t feel hard (but hard) to play. It’s a big family with love (but 800 hearts). On April 17th, seven members of Mengtan Family 3.0 shouted the program group one after another, and the funny tone attracted netizens to stop. The feature film has not yet started broadcasting, why is the program group being vomited by guests? The root cause is that ten minutes ago, the official blog of "Meng Detective 3" opened a welcoming ceremony for its members, throwing out "the truth" to the guests: the man who wants to Carry the audience with his brain after the reunification, the only royal sister who has kicked Sun Honglei in the whole network, and the "female rapper" who dominated the annual hot song list …… From the responses of the guests, it can be predicted that this program is really not simple!

This season’s "Meng Detective" is more ingenious in the choice and collocation of the guest lineup. The configuration of 2 old players and 5 new players makes the audience familiar and fresh. Recalling the hilarious interactions in the first season, such as Z.TAO’s "pestering" Sun Honglei to introduce his girlfriend, "ranting" Sun Honglei’s "wily old fox", it also made the audience look forward to the reunion of tell it to the judge. The different positioning and responsibilities of the seven players create more possibilities for the next program effect. Sun Honglei, the big brother, and the big sister are quietly sitting in the town, and their domineering is leaking all the way; Nana, a sister in the host industry, has the strongest variety effect and full control ability; Qian Sun, a new generation of floret, makes the program more youthful; What kind of sparks will Z.TAO, a sand sculpture idol, spark when he meets Naza, a stupid beauty? Xu Zhisheng, the "talk show vase", faced with the gathering of top-level "most powerful mouths" in the whole network, how will he fight back with professional skills? It is also a highlight of the program.

In the promo, Sun Honglei and Xu Zhisheng laugh at each other, seemingly harmonious but hiding the knife in the smile; Z.TAO was suspected of being anxious to speak Qingdao dialect; Quiet took the big sister’s demeanor and "thundered" Sun Honglei … Although the players have different roles and responsibilities, they all have the same characteristics, that is, expressing truth, having fun and being more adventurous. The gathering of seven "happy people with inner entertainment" will also fully link the audience’s emotions, have emotional interaction with them, and bring the "happy" experience to the extreme.

Funny reality show+explosive IP+ adventure upgrade three major points to create a happy interactive variety.

The slogan of "Meng Detective 3" will run through the whole season, so that the audience can not only enjoy watching, but also have fun! This season’s "Meng Detective" has upgraded its "adventure" experience. Guests should not only look for "undercover" in layers of fog, but also strive to escape from danger in danger. Such as the propaganda film, Nana shouted for help "let me out"; Naza took Qian Sun’s hand and running all the way fled the danger; The flight guests were blindfolded and locked in a dark room; The ups and downs of the plot game will bring a thrilling journey to the audience. The reality show game of joy and decompression has made the audience feel more happy! Such a variety show is definitely the best choice for suspense lovers and reality show lovers.

In addition, "Meng Detective 3" will continue the form of film and television plot investigation.

How to prevent norovirus infection and influenza? What conditions do you need to see a doctor? -experts answer hot issues on prevention and control of infectious diseases in spring.

  Xinhua News Agency, Beijing, February 25th  Question: How to prevent norovirus infection and influenza? What conditions do you need to see a doctor? — — Experts answer hot issues of infectious disease prevention and control in spring.

  Xinhua News Agency reporters Gu Tiancheng and Dong Ruifeng

  At the time of communication in winter and spring, the school season is also ushered in all parts of the country. Recently, some children with vomiting and diarrhea were diagnosed as Norovirus infection. At the same time, the results of influenza surveillance in local disease control institutions show that the current level of influenza virus activity in China has increased, mainly influenza A.

  What is norovirus infection and influenza, and how to prevent it? What conditions do you need to see a doctor? On the 25th, the National Health and Wellness Commission organized an authoritative expert, Wang Guiqiang, director of the Department of Infectious Diseases of the First Hospital of Peking University, to answer the public’s hot issues about the prevention and treatment of infectious diseases in spring.

  1. Q: What is Norovirus? What are the symptoms after infection?

  Wang Guiqiang: Norovirus belongs to the calicivirus family. After infection, the main symptoms are vomiting and diarrhea, which is an infectious disease of digestive tract. The source of infection is mainly from the mouth, but also through aerosol and close contact, such as primary school and kindergarten children holding and touching each other.

  From the clinical manifestations, the symptoms are mild and severe, most of which are vomiting and diarrhea, while others lead to severe vomiting and diarrhea, and some serious cases may have systemic symptoms such as fever. Vomiting and diarrhea can cause a lot of electrolyte water loss in human body. Therefore, after being infected with Norovirus, it is necessary to fully rehydrate, pay attention to rest, and take sugar salt water or use rehydration salt in time.

  2. Q: What do you need to see a doctor after being infected with Norovirus? How to prevent it?

  Wang Guiqiang: If young children and the elderly are infected with Norovirus and show weakness, apathy, dry mouth and dry eyes, these conditions may be hypotension. We should measure blood pressure in time, go to the hospital in time, and give corresponding rehydration in the hospital.

  If you dispose of it at home, you must pay attention to drinking light salt water or sugar salt water, because norovirus infection mainly leads to diarrhea and vomiting, which leads to the loss of a lot of electrolytes and water in the human body, which may have serious consequences. Some serious cases, such as elderly patients with basic diseases, may induce shock and other manifestations, so we should pay special attention to elderly patients with basic diseases.

  Norovirus is mainly transmitted through the digestive tract. The first thing to do well in prevention is to manage the hygiene of food and water sources safely. The second thing is to do well in hand hygiene and wash your hands before meals. In places where children’s care institutions, primary schools and other people gather, once an epidemic situation occurs, it is necessary to immediately check whether food and water sources are polluted, and key areas such as canteens must be carefully inspected and sterilized to avoid further spread.

  3. Q: What is the flu? What’s the difference with the common cold?

  Wang Guiqiang: Influenza is an acute respiratory infection caused by influenza virus. The actual difference between influenza and common cold is mainly in the degree of illness and pathogen.

  First, the etiology of the pathogen is different. There are many pathogens that can cause cold-like symptoms, and influenza is caused by influenza virus. At present, influenza A virus is more prevalent.

  Second, flu symptoms are more serious than the common cold. Influenza can lead to persistent high fever, aching muscles and joints all over the body, and severe pneumonia. At the same time, influenza has the risk of aggravating the basic diseases of the elderly, and some patients may have secondary infections, such as upper respiratory tract infection, tracheitis and secondary bacterial infections. The general symptoms of the common cold are mild.

  Third, in terms of treatment, influenza has specific drugs, and it is suggested that the sooner antiviral drugs are involved, the better. Although influenza is a self-limited disease, early use of drugs can shorten the course of disease, relieve symptoms and reduce the risk of severe illness. The common cold can generally be treated with symptomatic treatment. Drink plenty of water and pay attention to rest. There is no specific medicine.

  Fourth, from the perspective of prognosis and complications, influenza is relatively harmful, and some individuals may cause the risk of hospitalization or even death.

  4. Q: What symptoms do you need to see a doctor when you have the flu? How to prevent it?

  Wang Guiqiang: From the point of flu treatment, generally speaking, symptomatic support treatment is the main treatment. If there is persistent high fever, shortness of breath and aggravation of basic diseases, you should go to the hospital in time. Especially for the elderly with basic diseases, it is suggested that they should go to the hospital in time when they have symptoms of fever, cough, headache and fatigue. If they are diagnosed with influenza, they should use antiviral drugs as soon as possible to avoid further deterioration of the disease, which will lead to the aggravation of the basic diseases. At the same time, it is recommended to carry out influenza vaccination every autumn.

  Influenza is a respiratory infectious disease, and the prevention of respiratory infectious diseases is similar. Some measures to prevent Covid-19 infection are also measures to prevent influenza, and also help to reduce the risk of norovirus infection. Frequent ventilation, wearing a mask and good hand hygiene are all effective means to prevent influenza. In winter and spring, it is recommended that you wear masks in places where people gather or in closed spaces. Frequent hand washing, frequent ventilation and keeping social distance are effective in preventing all respiratory infectious diseases.

English Diet and China Restaurants Written by Zhou Songfang, Zhu Ziqing and Xia Nai.

In August, 1931, Zhu Ziqing went to England to study linguistics and English literature for one year because of Tsinghua’s system arrangement for teaching study leave, and traveled to five European countries. As a foodie, after returning home, he not only involved in eating in the Miscellaneous Notes on a European Journey, but also mentioned the list of Chinese restaurants he had eaten in his diary, which was more in the author’s bibliography, leaving valuable materials for us to understand the situation of Chinese restaurants in Britain, especially in London. Later, Mr. Xia Nai studied in London for more than four years, and also left many records of Chinese restaurants. Therefore, although I am in "Diet Journey to the West"(Sanlian Bookstore Life Bookstore 2021 Edition)There has been a special chapter "English Chinese Food: From Sailors’ Pavilion to Hong Kong Pavilion" to discuss English Chinese restaurants in the late Qing Dynasty and the Republic of China, but this large amount of new historical materials is still enough to become a new chapter.

Zhu ziqing

First, laugh and tease the British diet

Mr. Zhu Ziqing pointed out at the beginning of the article "London Miscellanies, Eating":

When it comes to eating and drinking in Europe, who always thinks of Paris, London is not. Needless to say, just fried yam eggs. French cut into small dominoes, yellow, oily and delicious; Britain’s "Chip" is half yellow and half black, neither too hot nor too cold, and there is no smell in it. You can only be full. Besides, English food is eaten, and the main course is nothing more than fried beef ribs with sheep and two vegetarian dishes; A family has lived for four months, and has only eaten fried veal liver once, which is a new trick.(Zhu Ziqing’s Miscellaneous Notes on European Tour, Sanlian Bookstore, 1983, 155 pages)

London Miscellanies

His friend, Mr. Lin Yutang, has also greatly derogated from the British diet:

British people do not take food seriously, but regard it as a casual thing. This dangerous attitude can be found in their national life. If they know the taste of food, there will be words to express this meaning in their language. There was no word "cooking" in English, and they only had "cooking". They didn’t have proper words to call "chef", but simply called it "cook"; They didn’t say "menu" originally, but just called it "‘dishes’"; They didn’t have a word to call "gourmet", so they called it "Greedy Gut" (greedy belly) in nursery rhymes. In fact, the British don’t admit that they have stomachs … What the British are interested in is how to keep healthy and strong, such as eating more Bovril beef juice, so as to resist the attack of colds and save medical expenses.(Lin Yutang’s Chinese, Xuelin Press, 1994, 325 pages)

Xu Zhongpei, a famous journalist who was a special correspondent of the Central Daily News in London, simply said: "There is no cooking in Britain. Any vegetables are cooked in white. I often say that being a chef in Britain is the easiest job in the world. Anyone who has been to Britain knows that English food is boring."(Xu Zhongpei, London and I China Restaurant, Central Daily Weekly, No.5, 1948. Xu Zhongpei sometimes writes Xu Zhongpei. For example, when this article was published in the seventh issue of 147 Pictorial in the name of China Restaurant in London, it was signed by Xu Zhongpei. )

Zhu Ziqing arrived in Paris by land from Soviet Russia and then went to England, so he ate French food first, which was quite cheap and good: "September 7, 1931, Paris: dinner at the French hotel was worth five francs and seventy-five centimes, one meat and two vegetables, and a bottle of beer was very cheap." Therefore, when I went to London, I ate French food first among foreign dishes, and I even thought it was cheap and good: "September 11, 1931, London: I ate at Lyon restaurant, which was cheap and didn’t take tips, which was very good." I went on the next day, but I didn’t feel so good: "September 12, 1931, London: Dinner at Lyon restaurant, the mutton was very poor, the account was miscalculated, and the rest of the language was not enough." As for going to a small restaurant in England, there is no comment: "October 18, 1931, London: I had dinner with Tao Jun and Wang Zhaojun at a barbecue restaurant in the evening." "October 19th, 1931, London: Lunch at Express Dairy." Probably because it tastes bad. It wasn’t until a month later (Wednesday, November 25th, 1931) that I ate in a relatively high-end Imperial Hotel, but "lunch is good, it is expensive"-the British can still make a good taste for a penny, but the price/performance ratio is not attractive enough, so I "agreed with Tao to go to Lyon restaurant on Friday night"; "December 30, 1931, London: Dine at Lyon Restaurant in Piccadilly Circus", and continue to eat cheap and good French food. Later, Zhu Ziqing also found a great British restaurant with good quality and low price: "On December 8, 1931,London: Go to the Oxford Corner Hotel for dinner with Tao in the evening. As Tu told me, this is the palace of the poor! This nickname was taken by some British students. It’s really the largest restaurant I’ve ever been to. This restaurant is not only huge, but also beautifully decorated and has a good band. We can sit upstairs until twelve o’clock. The food here is much better than ordinary restaurants. "(Collected Works of Zhu Ziqing, Volume 9, Jiangsu Education Press, 1998, pages 41, 42, 59, 77, 95 and 82)

The Oxford Corner Hotel is a "poor man’s palace", and the Imperial Hotel is only relatively high-end. Anyway, "the first-class hotel has never been there". In addition to French food, Italian food, which is famous in continental Europe, is impossible for Zhu Ziqing not to taste, although it is not a first-class hotel:

Italian restaurants have been to two. The family is in Oxford Street, which is quite large, and there are female jugglers and dancers at dinner. I only remember that the first course was oysters and the like; A special dish with seven or eight round squares around the side, each with an oyster, tastes very elegant. The other one, Euston Road, is also a busy place. This family is small, and Tongxin powder is the best; Cut the flour into small circles half a minute long, fry it in yellow oil, spread it flat on a plate and sprinkle with cheese powder, which is relaxed and delicious. There are also fried "gas oysters", which are tender and fragrant, and the crickets and scallops can’t be reached; Only the oyster yellow in Ningbo seems to be close at hand.

Zhu Ziqing stayed in London for a year, but he didn’t cook by himself. He "went to eat two meals a day". It is reasonable to say that there were many restaurants to eat, but apart from remembering several French and Italian restaurants (of course, there are many Chinese restaurants, which will be described later), British local restaurants don’t remember much, either because they are small shops or because they don’t like English restaurants very much. In his love letter to Chen Zhuyin, he also said very briefly: "Most restaurants here are hosted by women. I went to a shop that didn’t give small bills, and the hospitality was good and bad! Some hosts are really scary! If a waiter has long eyelashes, as if he can’t see anything, and another asks what food he wants, these two are the most annoying; They are in the same family, so I don’t go there often. "(Zhu Qiaosen’s "Zhu Ziqing’s Love Letters", letter dated October 21, 1931, Jiangsu Education Press, 2001, 75 pages)

Zhu Ziqing’s daily visit to this small restaurant is probably the tea restaurant that he thinks best represents British cooking:

Old city restaurants and tea restaurants are the local flavor. Tea restaurant and frying shop are actually nicknames for small restaurants. The "rice" in the tea restaurant originally refers to lunch, but the things sold are not simple, and dinner is full; Besides frying beef, lamb chops and ribs, the frying shop also sells other things.

There are three cheap tea restaurants: LYONS, Express Milk Room and ABC Bakery. Each family has opened many stores, all over the city and outside; ABC is less and more expensive, and Laaynes is the most. The fried veal, veal liver and braised duck pieces in the express dairy are also delicious; They burn duck pieces with charcoal fire, so it has a China flavor. ABC fried beef liver can also be eaten, but it’s almost impossible to get old in a hurry; The dim sum is well baked, and several of them are comparable to the French bakery in Beiping. There doesn’t seem to be anything outstanding in Laaynes; But there are two "corner shops" in his house, both at the corner of downtown, but there are delicious foods there. The corner shop has two large rooms, one is upper and lower, and the other is three floors and three large rooms, which can accommodate about 1,500 people. There is a band playing in the evening. As soon as I entered, I saw it was dark and full of people. The corridor was narrow enough, but the weather was quite wide (a British student ridiculed it as "the palace of the poor", which might be good); There I often find and stand for a long time before waiting for an empty seat.(Zhu Ziqing’s Miscellaneous Notes on European Travel, Sanlian Bookstore, 1983, pp. 157-158)

He briefly said these things in his diary, just wondering if this tea restaurant has something to do with the tea restaurants that have been popular in Hong Kong since then. For lack of materials, I won’t go into it for the time being, but the expression in one of his diaries is very close: "January 6, 1932, London: I talked with Liu in the morning. We had lunch in a nearby teahouse. This teahouse is only visited by some workers. "(Collected Works of Zhu Ziqing, Volume 9, Jiangsu Education Press, 1998, 99 pages)

Zhu Ziqing has nothing to say about English restaurants, but he has said many times about the cooking skills of himself and his friend’s landlord, which makes him feel a little abnormal:

November 1, 1931, London: In the morning, it is advisable to go to Xu Zijun’s place and visit Windhoek Carmen. Xu Jun lives in a family with only one guest. The landlord is a widow, originally from Germany. Xu Yunshan cooks and cooks chicken soup as China does. He eats chicken twice a week, and the whole meal is only thirty-five shillings.

December 26, 1931, London: I had breakfast at Liu’s residence. I think the food here is better than ours, because the landlady is very attentive to everything. She also invited us to stay with her all day. Her words are so polite and humble that we can’t refuse them easily.

December 31, 1931, London: The food in Mr. Fu’s residence was good, and I drank too much wine.(Collected Works of Zhu Ziqing, Volume 9, Jiangsu Education Press, 1998, pp. 64, 92 and 95)

In the love letter, he also specifically talked about the cooking skills of his new landlord, and said it better: "November 9, 1932: I moved here on Monday, and everything was still comfortable … The cook was very good and the food was delicious, but after eating well these two days, my stomach became uncomfortable. You can blame it. It’s really an unappreciated stomach."(Zhu Qiaosen’s Handwriting of Zhu Ziqing’s Love Letters, Jiangsu Education Press, 2001, 92 pages)

Second, gather in China restaurant.

Zhu Ziqing said in "Miscellaneous Notes on Europe Tour": "There are seven or eight China Hotels in London, which are very different in price, depending on the place. Although there are some high and low dishes, they are all Cantonese in disguise, far less good than Shanghai Xinya. I asked for a bowl of chicken wonton in a Guangdong building, which is one yuan and sixty cents in China, which is expensive enough. "(Zhu Ziqing’s Miscellaneous Notes on European Tour, Sanlian Bookstore, 1983, 158 pages)It seems too bad and too expensive. However, he went to almost every one of these seven or eight restaurants, leaving their names in his diary, and his impression of the food was far better than this published account. We might as well sort it out one by one. Among them, the one who went the most was Shundonglou, which was first seen in the pen, and was recorded four times:

September 15, 1931, London: Lunch is at Shundong Building, invited by Liu Zhongxi.

October 8, 1931, London: Visiting Liu Zhongxi Jun, meeting Wang Shufang Jun, and studying mechanical engineering in Manchester factory. I met Wu Dingliang Jun, who was a student of No.5 Normal University. I heard his name for a long time, and now I have a doctorate. I still studied statistics from Karl Pearson and thought of getting a doctorate in science. He is very knowledgeable. The canal asked Liu Jun to go to the East Building for dinner, and I also kept pace with it. As a result, wu jun was the host; It is also so troublesome to invite people to a meal in a foreign country.

November 13th, 1931, London: Invited Mr. Zhou to have dinner in Shundong Building, where he met two China ladies who spoke Shanghai dialect. I haven’t heard Shanghainese for two months! Their style and manners are also a Shanghai style, and I hate and admire them, which is really contradictory.

November 28, 1931, London: I had lunch with Liu and Lu in Shundong Building.

Nanjing building was also recorded four times, but the first two times were given a "very good" evaluation, and it was not too expensive!

October 3, 1931, London: The meal was in Nanjing House, one third (pound), one soup and two dishes. It was very good and the dishes were extremely abundant.

October 7, 1931, London: Lunch at Nanjing Building, very good.

October 10, 1931, London: When I went to Nanjing Building for lunch, I met a China student and cursed an American student, saying that there was someone who wrote a paper on the evolution of women’s socks (high waist) and menstrual belt.

December 28, 1931, London: Mr. Luo visited. He told me something about the Christmas party at Nanjing Hotel. He said that someone named He accused everyone of indulging in pleasure at the meeting, but he himself came to London from Cambridge for pleasure!

Xinhua Weizhai recorded three times, two of which were alumni dinners, with Peking University alumni and Tsinghua alumni respectively; In my humble opinion, this is also a Chinese restaurant that has never been seen by others:

December 23, 1931, London: Old alumni of Peking University in London held a luncheon in Xinhua Weizhai, where everyone held a long talk.

December 27, 1931, London: Mr. Jia was invited to have lunch at Xinhua Weizhai.

January 1, 1932, London: Dinner with alumni from Tsinghua University in Xinhua Weizhai.

From the gathering of Nanjing Building mentioned above to the gathering of Xinhua Weizhai, Chinese restaurants are really the gathering place for international students, and Shanghai Building is famous for the gathering of Peking University alumni:

September 24th, 1931, London: Dinner at the Shanghai Building was rare in Chinese. The food is not bad

February 27, 1932, London: Dinner at Shanghai Building, which is famous in London for the gathering of Peking University alumni. At three o’clock, Lin Yutang gave a speech on "The Spirit of the Times of China Culture", and the discussion was very lively and interesting.

In addition to the above Chinese restaurants, Zhu Ziqing also visited Huaying Building and Xinyue Restaurant occasionally:

September 15, 1931, London: Dinner was invited by Mr. Luo, in Huaying Building, inferior to Shundong Building.

January 31, 1932, London: Attended the banquet of Dr. Lin (Yutang) at Xinyue Restaurant. After lunch, go to his place with him. He talked to me about his plans for a Chinese typewriter.(Collected Works of Zhu Ziqing, Volume IX, Jiangsu Education Press, 1998, pp. 43, 54, 70, 78, 51, 53, 55, 94, 89, 93, 97, 46, 118, 43 and 109)

Of course, these are not necessarily Mr. Zhu Ziqing’s complete records, and he has no obligation to remember them in every family. As far as I know, there are six restaurants, namely Shundong Building, Nanjing Hotel, Xinhua Weizhai Building, Shanghai Building, Huaying Building and Xinyue Restaurant, which are generally consistent with the seven or eight he mentioned in London Miscellanies-because he didn’t or didn’t want to or dared to go to the first-class hotel, while the most famous Chinese restaurants in Britain at that time were Xinghua Building and Flower Exploration Building. Mr. Hua Wu (Guo Zixiong) said: "The most luxurious apricot blossom building in Oxford Street was originally the first China restaurant in London. Most of the employers were outsiders, so poor students could not afford it." In Hua Wu’s pen, the flower exploration building can also be called a first-class hotel: "The flower exploration building at the bottom of the wall is very ostentatious, and poor students are not allowed to go."(London Sketch China Restaurant, Cosmic Wind, No.1, 1935)Expensive is only one aspect, and the key is delicious, otherwise it will be unkind; The Flower Exploration Building is worthy of its high price: "There are five or six China restaurants in London, and the equipment is good or bad. The Flower Exploration Building is the most expensive, and the food tastes similar. The expensive food is also very good, which is comparable to Shanghai’s elegance, but the cheap one will not work."(Mao Yugong’s Life in Britain, Jiaotong University Alumni, No.3, 1937, pp. 31-33)

Business Magazine, Volume 5, No.1, 1930, London Xinghualou Restaurant

Zhu Ziqing and poor students can’t afford to go to the Xinghua Building and the Flower Exploration Building, so who should go? The dignitaries can go. For example, when Hu Die, the winner of the film, visited Europe and arrived in Britain in 1935, she was seated here: "I had lunch at the Flower Exploration Building, and I met the Mr. Li, his wife and relatives I met in Paris. This gentleman is not only from Guangdong, but also from Heshan County, which is the same county as me. "(Hu Die’s Miscellaneous Notes on European Travel, Shanghai Liangyou Book Company, 1935, 97 pages)The Flower Exploration Building is often a place of diplomatic protocol: "Formal banquets or foreign guests of both sexes will accompany them to the Flower Exploration Building. The facilities in the restaurant are gorgeous, and the waiters in dresses are very arrogant. They open champagne, chew shark’s fin and drink bird’s nest soup during the music performance. Although it is somewhat incongruous, it is enough for ostentation and extravagance."(Jing Qing’s Talking about Eating, New China, Volume 3, No.20, 1935)As early as 1924, Liang Shiyi, the former Premier of the State, set off for Europe and America on March 5, and had a banquet with Ke Sze Sao, the British ambassador to the United States, in Tanhua Building on July 7 in London. In the evening, the farewell party of the British embassy is also in the Flower Exploration Building.(Chronicle of Liang Shiyi, edited by Fenggang and his disciples, Guangdong People’s Publishing House, 2014, 350 pages)

However, the new flower-exploring building opened later was unexpectedly cheap and fine, but strangely it belonged to the same boss:

I’m in China Restaurant in London, and I almost always go to the new flower exploration building in Wardour street, Piccadilly. Chinese eats a lot there, and gives special treatment to our own China compatriots. There are company dishes, about one shilling and nine servings for one person. There is already one soup and two stir-fried, and the rice is as full as possible, and there is a pot of good rain. The quality of western food is richer than that of five shillings. When I first arrived in London, I unfortunately ran to a flower exploration building, also in Piccadilly, which was opened by the same owner as the new flower exploration building. There is no company food there, and a bowl of sliced pork soup is not enough unless it is five shillings. Later, I went several times before I learned about this new flower exploration building. So in the future, in London, where the living standard is very high, I found this cheap and good canteen to satisfy my hunger.(Cang Sheng’s Miscellaneous Notes on Europe, Life in London, People’s Weekly, No.26, 1935)

Cang Sheng said that the food in Tanhualou was expensive but not delicious, probably because he was not used to the lightness of high-grade Cantonese food. And this is a calculation, and it has exceeded seven or eight. In fact, it is far more than these seven or eight. Jingbo, who came to Britain almost at the same time as Zhu Ziqing, mentioned a elegant building: "There are also several China restaurants in London, and sometimes they go there to satisfy their cravings. Because I’m tired of eating ham and eggs, and I’m just as uninterested as Japanese’ Misuo Xi Lu’, so we often find traces of Daya Building and Nanjing Building. "(Jing Bo’s Life of British Overseas Students, Reading Magazine, Volume 1, No.2, 1931)Mr. Yu Pingbo, who came earlier than Zhu Ziqing, has been in London for less than half a month, but he has repeatedly mentioned a China Lou Chinese restaurant:

On February 22, 1920, I drove at 8: 35 (from Liverpool) and arrived in London at 2 pm. Chen, Wu and Ren Junjun came to meet them and went to the Students’ Union in Britain. ….. Night in China building for dinner, and talk to the club.

24th: In the afternoon, I was managing things. It takes fifty shillings a week to find a house in Qian Yi Chenopodium to the southwest. Dinner at China Building in the evening.

February 28th: In the afternoon, Qian came to Fuyu and met Chen Jun (Xiying). Chen asked Ren, Fu and I to have dinner in China.

March 1st: Xie Fu invited Wu, Ren, Chen, Yang and Zhang to dinner in China Building.(The Complete Works of Yu Pingbo, Volume 10, Huashan Literature and Art Publishing House, 1997, Foreign Diary, A, pp. 162-163)

Two or three years later, Xia Nai, who came to the University of London in the autumn of 1935 to study archaeology and later became a famous archaeologist, went to restaurants from time to time and basically only went to Chinese restaurants, but said that "there are five China hotels in London", which is obviously a glimpse of the scholar-he has eaten more than five Chinese restaurants later, and he has never been to such famous restaurants as Xinghualou and Tanhualou. Besides, he can’t afford to go or he can’t bear to go. It is not easy to study because of the prosperity of the anti-Japanese war, and he wants to study for a few more years with limited funds; By August 31, 1938, his public expenses had expired, and "research work, beaded cataloging, reached No.360", although fruitful, was still not finished. "The accumulation of frugality and food was enough for more than one year", so although I lamented "three years of overseas blood and tears", why bother! " Still insisted on returning to China through Egypt after the outbreak of World War II in Europe in the autumn of 1939. However, he worked in Cairo Museum for more than a year before arriving in Kunming in early 1941 via West Asia, India and Myanmar. "His doctorate in Egyptian archaeology from London University was awarded in 1946 after the war."(Diary of Xia Nai, East China Normal University Press, 2011 edition, Volume II, page 225, with Wang Zhongshu’s Biography of Mr. Xia Nai attached to the first book).

Xia Nai

Like Zhu Ziqing, the Chinese restaurant that Xia Nai visited the most was Shundong Building, and as soon as he arrived in London, he went: "September 3, 1935: arrived in London at 6 pm … and went to Shundong Building to eat Chinese food." The next day, I went again: "September 6, 1935: In the afternoon, Tan (Ji Fu), Zeng (Soyul) and Zhou (Jianbei) came to Shun East Building for dinner." Then I rented a good room (September 6, 1935), "My bedroom is 35 shillings a week, including meals", but I still often go to Chinese restaurants, which is still the first choice for Shundong Building:

September 27th, 1935: I visited Tan Jifu Jun with Chen Fengshu Jun in the morning. He came from Birmingham and will go back to school next week. In the afternoon, I went to the city to watch movies. After the break, I went to Shun East Building to eat Chinese food and drink beer. There were 7 people present (Tan Jun, Zhou Jun, Zeng, Chen and I), and Chen Jun was the host, which cost a total of 35 shillings. The food is not expensive, 2 shillings for each guest, and 1 shilling for a bottle of beer. Even I can drink two bottles, and I drank 15 bottles in total (the small bottle can only hold one cup).

October 6, 1935: At the invitation of Wu Jinding Jun, I went into the city and arrived at Shundong Building. It was originally scheduled to be 12: 30. Today is the first day of winter. The clock in London was set back at 1: 00, and the rest was still at 11: 30. I strolled nearby, including Beijing Building, New Flower Exploration Building and New China Building. (Press: The Beijing Building and the New China Building, which were not mentioned by the above-mentioned scholars)

November 20, 1935: I went to Li Chaoying for an appointment with Jun, and went to Shundong Building for lunch. Mrs. Li Jun was also present, and she was from Hangzhou.

November 22, 1935: Lin Changfeng and Li Chaoying were scheduled to eat together in Shundong Building, and Li Furen was also present.

During the first few months in London in 1935, I only went to Shundonglou and never went to other Chinese restaurants. I really loved it. Dear, go on. In 1936, I first went to the Beijing Building: "February 6, 1936: I went to the British Museum with Wu Jun and had lunch with the Beijing Building to talk casually about the archaeology in China." Throughout the year, except for this time, I have been to Beijing Building, and the rest have continued to go to Shundong Building:

July 25th, 1936: I went to town with Chen Jun, and went to Shundong Building for dinner. Take the 3 o’clock train to Dorchester.

September 14th, 1936: Visit Tang Xiang Long Jun at Guilford Street (guildford Street) and have lunch with Shun Dong Lou.

October 7, 1936: In the afternoon, I went to the British Museum, met with Xiang Juemingjun, talked until the evening, and went to the Shundong Building for dinner.

Next, shortly after the beginning of the new year in 1937, I went out to eat for the first time, and went to a Chinese restaurant and Shun East Building: "January 9, 1937: I went to Wu Qiyuan’s place with Chen Jun in the afternoon, Luo Fengchao and Li Mingqijun lived in a room with Wu Jun, played bridge and went to Shun East Building for dinner." There is a Beiping Building in the middle: "January 23, 1937: I made an appointment with Mr. Li (Ji), Mr. and Mrs. wu jun, Xiang Jueming and Zeng Zhaosui to have dinner at Beiping Building." The rest are basically going to Shun East Building:

February 7, 1937: I went to Zhong Daoming’s appointment and had lunch at Shundong Building. Mr. Li (Ji Zhi) and Mr. wu jun were also present.

May 12, 1937: To China Restaurant, the price was increased today (the coronation day of the Emperor), and a meal cost 3 shillings, which can be described as a rip-off. We’ll call it noodle soup instead, at a shilling and a half. (Press: The restaurant that is so familiar, although it is not clearly said which one, is probably Shundong Building. )

May 17th, 1937: In the evening, I had dinner with Zhong, Zhou, Tang and Chen Sijun in Shundong Building.

May 21, 1937: I went to the Royal Hills and met Mr. Li (Ji). Mr. Li was dissatisfied with the French and German students, saying that they played with women and didn’t study. Less than 10% of the 400 people in Germany actually studied. The companion went to Charing Cross Street to buy books, and went to Shun East Building for dinner.

May 27th, 1937: This week, I continued to listen to Rostovtzeff’s lecture, and I came to listen to Jue Ming and Zeng Zhaosui. Tonight, I went to Shun Dong Lou for dinner with Erjun. wu jun and Pan Jun were present and talked until 10: 30.

June 6, 1937: wu jun and Zeng Jun were invited to dinner in Shundong Building to chat about the domestic archaeological community.

June 12, 1937: In the evening, I had dinner with Tang Xiang Long Jun in Shundong Building, and went to Wu (Jinding) Jun to get his paper.

Since then, the Beijing Building and the Shun East Building have alternated, but the Shun East Building is still the main one:

June 19th, 1937: Zhong Daoming was invited to dinner at the Beijing Building, so that Zhong Jun would return to China next month.

June 27th, 1937: At the invitation of Jun, we should have a dinner in Shundong Building in the evening to see Ms. Zeng and Mr. and Mrs. wu jun off.

July 11th, 1937: china christian council and China Association welcomed Liu Tingfang and Wei Zhuomin, and Cheng Yaosheng invited me to attend. After the meeting, I went to the Beijing Building for dinner with Chen Fengshu and Li Mingbian, and everyone was indignant when I met Zhang Dechang.

July 20, 1937: In the evening, I went to Wu Jun’s appointment and had dinner in Beijing Building.

July 21st, 1937: wu jun and his wife, Zhong Xiang and Zhu Jun had lunch together in Shundong Building.

July 27, 1937: In the evening, I met Tang Jun and Zhong Erjun in Shundong Building, and chatted with Tang Jun, so that Tang Jun would leave England for France the day after tomorrow.

September 15th, 1937: Arrived in London in the evening, found a hotel for Zhu Jun and invited him to Beijing Tower for China dinner.

June 4, 1938: Chen Jun was invited to Beiping Building for dinner in the evening to congratulate him on his master’s degree. Zhu Qingyong is your company.

November 12, 1938: Yesterday in the China Association, I met Huang Zongshijun, a military student, and graduated from No.10 Middle School. He was not at the same level as Wu Xuerong and was from Rui ‘an. Today, let’s go to Oxford for sightseeing … Return to London and have dinner in Shundong Building.

December 4, 1938: In the afternoon, at the invitation of Wang Shengzu, he went to his apartment. Zhu Jun and Wang Tieya Jun were also present. After playing bridge and tea, he continued to stay in the evening and went to Shundong Building for dinner.

June 25th, 1939: Yesterday, Mr. Wang Weicheng came from Oxford, and Mr. Zhu Qingshui had lunch together in Shundong Building.

June 30, 1939: Guide Wang Jun to visit the school building, the Chinese Department Museum and the exhibition of E.E.S. (Egyptian Exploration Society). In the evening, I had dinner with Zhang Zongsui, Xu Baolu Jun and others in Shundong Building.

July 24, 1939: The Anti-Japanese War Daily began to be compiled today, and it arrived every two weeks in turn. Braving the heavy rain to report to the Chinese Association, I came across Mr. Yuan Jiahua, invited him to Shun East Building for China dinner, led him to his apartment, and chatted until 10 o’clock.

September 24, 1938: Wang Weicheng came from Oxford and invited him to Shun East Building for dinner.(Diary of Xia Nai, East China Normal University Press, 2011 edition, Volume I, pages 356-357, 368, 372 and 392; Volume II, pages 10, 56, 69, 74, 88, 90, 92, 109-114, 116-118, 125, 215-216, 232, 233, 249, 250, 252, 260 and 264).

Among the English Chinese restaurants written by most scholars or literati in the Republic of China, Shundong Building is certainly not as high-end and famous as Xinghua Building and Flower Exploration Building, but only the traces of Zhu Ziqing and Xia Nai in those years and the stories of scholars written by them are enough to last for a long time.

China Restaurant in London, Volume 4, No.6, 147 Pictorial, 1946.

Zhu Ziqing occasionally goes to Shanghai Building and Huaying Building, while Xia Nai occasionally goes to Shanghai Building and Zhongshan Building:

September 28th, 1939: At noon, Professor glanville was invited for lunch in Shanghai Building, accompanied by Dr. baumgartel and Miss Macharge (Miss Macharg).

October 21, 1939: The landlord and his wife treated me well. Last week, they took the opportunity of the landlord to leave the camp and invited them to Zhongshan Building for a banquet.(Diary of Xia Nai, Volume II, East China Normal University Press, 2011, pages 260 and 264)

Zhongshan Building is unknown, but Shanghai Building and Huaying Building are quite stories. For example, Xu Zhongpei, a famous reporter of the Central Daily News in London, has a soft spot for Shanghai buildings. She wrote in "London and Me: China Restaurant": "My favorite restaurant is the Shanghai Building, which is located in Greek Street and presided over by a lady of mixed Chinese and English. This restaurant was originally opened by a Chinese. He married an English wife and had a large number of children. When he died, he entrusted the management of his life to the big lady, and the big lady did not live up to it. He managed it prosperously. I think the first reason why I like Shanghai Building is that it has a quiet environment, but the biggest reason is that it has two dishes, one is sausage, the other is tofu, and I can occasionally eat vermicelli soup there. Later, we became acquainted with our eldest sister, who often served us a dish of fermented bean curd with our thanks. "(Xu Zhongpei’s London and I China Restaurant, Central Daily Weekly, No.5, 1948)

Jing Qing’s "Talking about Eating" is also written in the Shanghai Building. In her opinion, it’s just a small restaurant that eats snacks: "Young tycoons, wealthy residents and businessmen, large and small diplomats of embassies … when they have casual snacks, they will go to the Shanghai Building or Shundong Building, and formal banquets or male and female foreign guests will accompany them to the Flower Exploration Building."

In the records of the late 1940s, Shanghai seems to be the top Chinese restaurant: "There are about 30 restaurants in China in London, but only Shanghai Tower and World are appreciated by Chinese himself. The Shanghai building is exceptionally elegant, with two or three elegant rooms and halls, walls full of famous paintings and calligraphy, and several landscapes and figures of Hunan embroidery. With these things, we can also attract western customers and comfort the official and business students from the motherland who go to Britain. In addition to painting and calligraphy, the world also has the scenery of China with oil paintings on the walls, which is also unique. As for the cups, plates and bowls of porcelain, ivory chopsticks are even more exquisite than ordinary restaurants in China.(Tan Naxi’s Memories of Traveling Around: Newspaper Street and China Restaurant in London, Central Daily Weekly, No.10, 1947)If you don’t dare, you must.

Huaying Building is near the New Oxford Street, where Mr. Hua Wu (Guo Zixiong) first ate in London. Its boss is a Cantonese. It is said that he first worked as a servant in another China restaurant. Later, after earning a few dollars, he opened this restaurant alone. His wife is his colleague who used to work as a servant, and from the following description, she should be an English woman. And it is his foreign wife who shows his demeanor:

This proprietress is in her thirties, wearing a pair of small glasses, and her attitude is very mild. Sometimes her classmates catch a cold, so she gives you some medicine to eat, which is very effective. Later, the boss of Huaying Building gave up his business and returned to Guangdong with his wife and two children. Before leaving, the proprietress said, "My husband is Chinese, I want to be Chinese, and my son has to be Chinese and study China. Like you, you will work for your country in the future. I can’t live here permanently and let my sons grow up here, so that when they grow up, the British don’t recognize them as British and Chinese doesn’t recognize them as Chinese. For them, let’s go back to China. China is our country, right? "(Hua Wu’s Sketch of London China Restaurant, Cosmic Wind, No.9, 1936)

In his love letter to Chen Zhuyin during his study tour in Britain, Mr. Zhu Ziqing wrote that "most hotels here are hosted by women" and that "there are also one or two male students who marry Chinese and foreign hybrid women and foreign women, but all of them are waitresses, and no matter how high they are, they will not marry Chinese".(Zhu Qiaosen’s Handwriting of Zhu Ziqing’s Love Letters, Jiangsu Education Press, 2001, 75 pages)Why don’t you write about the hostess in these Chinese restaurants? It’s a pity.

59 people in South Korea died after being vaccinated with influenza. Can they be vaccinated safely?

According to South Korean media reports, as of October 26, South Korea has reported 59 deaths after influenza vaccination. Although people are worried and the number of people vaccinated has dropped sharply, the government has not stopped.

South Korean President Moon Jae in said at the meeting in Cheongwadae that there was no direct causal relationship between the deaths after influenza vaccination and vaccination. In order to prevent influenza and the simultaneous infection and spread of influenza and COVID-19, it is necessary to continue to expand the scope of influenza vaccination. I hope that people will not be too upset, miss the timely vaccination, and accidentally catch the flu with a high mortality rate, which will lead to greater danger.

It is reported that most of the cases that died after influenza vaccination were elderly people over 70 years old, and the shortest death was 4 hours after vaccination, and a 17-year-old boy died 2 days after vaccination.

Every winter and spring is the high-incidence season of influenza. At present, the whole world is in the epidemic stage of COVID-19. Academician Wang Chen, Dr. Zhang Wenhong and other experts recommend influenza vaccination to avoid catching the flu, reduce the chance of going to a fever clinic, and also reduce the chance of co-infection of two viruses and reduce a hidden danger.

Therefore, there are many people in China who want to get the flu vaccine, and there is a great demand for the vaccine. So, how can we vaccinate safely?

Why do vaccination have serious adverse reactions?

First of all, one thing must be affirmed: the vaccine ingredients contained in the flu vaccine will not cause the flu.

But at the same time, as a medicine, influenza vaccine is not absolutely safe. There are a lot of possible adverse reactions, such as redness, induration, pain and burning sensation at the inoculation site. A few people may have systemic reactions, such as fever, headache, dizziness, lethargy, fatigue, myalgia, general discomfort, nausea, vomiting, abdominal pain and diarrhea. Most people’s adverse reactions are mild, which can disappear by themselves within 3 days. Serious adverse reactions are very rare. There is no difference in safety between tetravalent influenza vaccine and trivalent influenza vaccine; There is no significant difference in safety between domestic and imported influenza vaccines. Adverse reactions may be related to the following three reasons:

One is immune response. Because influenza vaccine is a medicine made by processing, inactivating, sterilizing and cracking influenza virus, it will simulate the immune response induced by real virus and promote the body to produce antibodies, which is often accompanied by various adverse reactions.

Second, trace endotoxin and impurities may remain in the process of influenza vaccine production and preparation.

Third, it may be a coupling reaction. That is to say, when the flu vaccine is injected, it may just be the incubation period of other diseases, and after the flu vaccine is injected, the disease will break out.

No matter what causes it, if the body’s immune response is too intense, or the original disease is aggravated and serious, and it is not treated in time and properly, serious adverse reactions may occur.

One of the serious adverse reactions is Guillain-Barre syndrome (GBS). The annual incidence of GBS in the general population is 10 ~ 20 cases per 1 million adults, which is very rare.

The other is immediate hypersensitivity. Any vaccine has the risk of immediate hypersensitivity. Severe anaphylaxis may be life-threatening, and it usually occurs within minutes to hours after inoculation. Its symptoms include urticaria, angioedema, severe anaphylaxis, etc. The incidence rate is usually 1-2 cases per million people.

Two types of people prone to adverse reactions

Adverse reactions after influenza vaccination may be related to the sensitivity of the immune system of people of different ages. Because children and young people are more sensitive, a slight invasion of harmful substances such as viruses will trigger obvious immune reactions, so the probability of adverse reactions will increase; On the other hand, with the increase of age, the elderly are prone to chronic pain, which is stubborn and difficult to treat. Therefore, all kinds of pain after vaccination will be covered up by chronic pain, so they think that they have no adverse reactions and delayed treatment.

Children: The probability of adverse reactions after influenza vaccination is higher than that of adults, and the most common one is fever. The younger the age, the higher the probability of fever, but it usually disappears on its own after 1-2 days of vaccination. At the same time, the risk of febrile convulsion in children within 1 ~ 2 days after vaccination will also increase.

Elderly: The most common adverse events in adults include injection site pain, fever, myalgia and headache; In the elderly, the pain at the inoculation site is the most common, but the duration is generally less than 2 days, and the degree is usually slight, which basically does not affect daily activities.

A large number of data show that vaccination with inactivated influenza vaccine will not harm pregnant women and fetuses, and will not increase the risk of congenital malformation of fetuses.

Precautions for vaccination

Contraindications for influenza vaccination are those who are allergic to any ingredients (including excipients, formaldehyde, cracking agents and antibiotics) contained in the vaccine; Patients with mild to moderate acute diseases with or without fever symptoms are advised to be vaccinated after the symptoms subside.

It should also be noted that people who are allergic to eggs are not taboo at present, so people who are allergic to eggs can be vaccinated against influenza.

Influenza vaccination can be given during the prevention and treatment of influenza antiviral drugs, and it is suggested that the elderly over 65 should be vaccinated with influenza vaccine and pneumococcal vaccine at the same time.

The common causes of adverse reactions are fasting and psychological factors, and the treatment methods are drinking warm sugar water, keeping warm and keeping a quiet and comfortable environment, and making appropriate psychological adjustment. Local pain and redness can be treated with local dry and hot compress; Respiratory symptoms such as dry mouth and cough can be relieved by drinking warm water.

However, if you feel unwell after vaccination, you should communicate with the doctor of the vaccination institution in time. If the symptoms have not subsided for more than 3 days, you should see a doctor in time.

In a word, influenza has always been an infectious disease that is harmful to health. Now it is the epidemic period in COVID-19. Vaccination of influenza can not only protect itself from influenza virus infection, but also play a good barrier role in the occurrence of influenza in groups. Influenza vaccination should be actively carried out, especially for high-risk groups such as the elderly, children and pregnant women.

Breaking away from "fifty cents special effects" (II): A small survey on the survival of special effects artists


  1905 movie network exclusive feature A little different from previous years, in 2015, a lot of "Machamp’s chaotic gods" emerged in the mainland film market, from the devil’s world in Zhong Kui to the radish essence in monster hunt, from the sinking of the ice sea in Taiping Wheel to the Kunlun avalanche in the Nine-story Demon Tower, from the alien ball in Unbelievable to the dragon-seeking tactic. … The endless emergence of special effects blockbusters fully shows the increasingly abundant imagination and emboldened technological progress of Chinese films.

 

  It may surprise you that 49 of the 50 best box office movies in history are told by special effects characters. While people are enjoying the visual bombing with relish while drinking cola and chewing popcorn, have they ever thought about what kind of people are the special effects artists who created these screen wonders that are fake and cool? Is an artist who is unrestrained? Or is it a bitter science and engineering house? What is their income? How are they doing?

 

  With this problem, 1905 Film Network made a special trip to interview several special effects artists from internationally renowned visual effects companies Pixomondo and VHQ, as well as other "veterans" who once struggled in the front line, to reveal the unknown ups and downs of special effects artists behind their glamorous works … …

 

Self-cultivation of special effects artists: artists? Engineer? Or a craftsman?

 

  As the "behind-the-scenes hero" of the film industry, the jobs of makeup, fine arts, photography, editing, music and sound effects have a long history, and ordinary audiences probably know what these jobs are for even if they have never made a film. The special effects artist is newly born in the wave of film digitalization in the past two or three decades, and his professional characteristics of emphasizing the combination of art and technology are very mysterious and avant-garde. Ordinary movie fans may have heard more or less about green screen synthesis, CG characters, digital landscape painting and motion capture, and even know a little about their production process. However, what kind of people are special effects artists, but they may not understand them.

 

  In the interview, we found that this seemingly tall industry actually has a low entry threshold. Compared with music and art, which need years of "children’s work" accumulation, the practitioners in the special effects industry may come from any major: some art school students who have learned to paint since childhood "push the boat with the current", and some science and technology houses "become monks halfway" because of their obsession and love; The educational level of the practitioners is also uneven: there are regular troops majoring in digital art from famous schools, and there are also masters of "returnees" who are striving for perfection. Of course, in China, most practitioners actually come from various short-term and medium-term training courses in the society.

 

  However, if you think that the special effects artist is a "simple" job, you are all wet — — Although most low-level special effects artists are really doing a lot of seemingly boring mechanical work, in fact, it is almost endless to deepen this work — — Especially for special effects artists who are exposed to three-dimensional special effects, when encountering projects with special needs, the existing plug-ins often cannot meet the needs. At this time, special effects artists need to "tailor" and develop new tools for specific projects.

 

  For example, in the 10-minute fighting between wolves and horses on a snowy night in Wolf Totem, VHQ, which is in charge of the special effects part, not only created a realistic series of CG wolves and CG horses, but also made a special snowstorm system. Guo Yiran, who is in charge of this "heavy project", recalled: "The snow we usually see usually floats down, but the amount of snow on the Inner Mongolia prairie is very large, and the wind is particularly strong, like white wool snow is intermittent, and some snow on the ground is blown up again." In order to easily adjust the direction, amount and shape of the snowstorm in the picture, the special effects department just spent a month to create this blizzard system, and then put it in each shot after completion, and then adjust it according to different scenes.

 

  It can be seen that special effects artists not only need good artistic intuition, but also have high requirements for technology and tools, and the latter often plays a more critical role in the process operation of large-scale projects. Although in the eyes of many ignorant and whimsical directors and producers, special effects artists are just technicians and engineers at best; Although in the industry, special effects companies often declare that their employees are "artists", Li Da, a special effects artist from Pixomondo, put forward a more accurate term for his career orientation — — "Art engineer".
