At present, the situation of epidemic prevention and control in China continues to improve, and foreign epidemics spread rapidly. "External defense input and internal defense rebound" has become the focus of epidemic prevention and control in China. Can I take off my mask now? How contagious are asymptomatic infected people and relapsing patients? Will pets spread viruses? Recently, Zhong Nanshan, an academician of China Academy of Engineering, responded to the hot issues of epidemic prevention and control.

　　It’s not time to take off the mask yet.

　　Zhong Nanshan:At present, the situation at home and abroad is very different. China has entered the second stage of the epidemic because of its decisive measures, while other major countries are still in the first stage of the outbreak and are still climbing up. This means that the probability of human-to-human transmission is very high, and the number of confirmed cases increases very quickly.Wearing a mask is still an important means of self-protection, but it is not necessary to wear it in areas where the epidemic situation is not serious, places with few people or open spaces.

　　Wuhan has passed the customs, but there is still the next pass.

　　Zhong Nanshan:After the outbreak, the central government took decisive measures to control Wuhan’s urban traffic, and it was very successful to take measures to prevent and treat it in other places. In the history of epidemic prevention and control, this is also a feat. However, there are still two tests: one is how to prevent and control while returning to work, and the other is the "external defense input" barrier.At present, foreign epidemic situation is still at the peak, and some coastal cities in China, which have close communication with foreign countries, are easily "involved", and then some epidemic situations occur.It can be said that the next "pass" of Wuhan is also the "pass" of the whole country, and it needs to pass through various prevention and control measures.

　　3. It is very unlikely that foreign imports will cause a second outbreak in China.

　　Zhong Nanshan:There are actually two questions about whether the overseas epidemic will cause a second outbreak of the domestic epidemic: first, whether the imported cases have spread, and second, whether they will break out in the process of spreading. The risk of transmission of imported cases definitely exists, especially cases with positive nucleic acid test or symptoms of infection, which are highly contagious and will cause virus transmission. At present, the mass prevention and control in China has been sinking into the community, and community residents have a strong sense of self-protection, such as wearing masks and keeping a distance from others. Once someone has symptoms such as fever, he can report or accept diagnosis quickly, and then isolate.On the whole, the risk of community transmission certainly exists, but the probability of the second wave of outbreaks in China is very small.

　　It is too early to talk about the "turning point" of the global epidemic.

　　Zhong Nanshan:Globally, the original "epicenter" of the epidemic was in Europe, especially Spain and Italy, and now it also includes Germany, France and Britain.The biggest problem at present is the United States. In the past week, the number of confirmed cases in the United States has increased at a rate of 10,000 to 20,000 per day. It is too early to predict when the global epidemic will have an "inflection point".It can be said that whether there can be an "inflection point" mainly depends on whether governments can intervene strongly. There are many unpredictable factors in other countries. According to the current situation, I am afraid it will take another two weeks.

　　5. The proportion of asymptomatic infected people in China will not be large.

　　Zhong Nanshan:Asymptomatic infected people do not appear out of thin air, but usually appear in two groups: first, people who have not shown symptoms for the time being but may have been infected in areas with relatively serious epidemics; The other is the close contacts of the confirmed cases, and their proportion is relatively small. Asymptomatic infected people also have two concepts. One is that they have no symptoms at first, but then they will gradually develop into symptoms. Such patients are definitely contagious; The other is that during a long observation, there is no symptom all the time, but the nucleic acid test is positive. We are studying the infectivity of such patients.However, according to the characteristics of Covid-19, once symptoms appear, it is more contagious, so it is correct to isolate asymptomatic infected people for observation.

　　6. Most patients with relapse are not contagious.

　　Zhong Nanshan:Generally speaking, most patients with relapse are not contagious. Most of the so-called multiple positives are fragments of nucleic acid, not the virus itself.We need to pay attention to two situations. The first is whether the patient has a relapse. If the patient produces strong antibodies, he will not be infected again. As for whether patients with relapsing yang will be transmitted to others, it needs specific analysis. Generally speaking, nucleic acid fragments are not contagious. Some scholars have cultivated throat swabs and secretions of patients with relapsing yang, but they have not cultivated viruses. The second situation is that patients have many basic diseases, but their symptoms have improved and they have not fully recovered. These patients cannot rule out infectivity.

　　7. There is not enough evidence of "influenza" in COVID-19.

　　Zhong Nanshan:At present, there is not enough evidence of COVID-19’s "influenza".Unless there is such a rule in virus transmission: its infectivity is still strong, but the mortality rate is getting lower and lower. In this case, it is possible to exist for a long time. We now need to make long-term observation and master sufficient data and cases before we can draw such a view. Under the present circumstances, I don’t think this prediction will come true.

　　8. It is too early to draw conclusions about animal-to-animal transmission.

　　Zhong Nanshan:It remains to be seen whether some animals such as dogs, cats and tigers are positive for nucleic acid detection, which is caused by pollution or infection. Some animals originally carry some viruses, which may not be symptomatic or contagious.It is too early to conclude that Covid-19 in these animals can infect both humans and animals, and both can cause diseases.

　　9. Some effective drugs have been found, but there is no specific drug yet.

　　Zhong Nanshan:Some drugs we are testing now (such as chloroquine phosphate) are definitely effective. We are summarizing them and will announce them soon. There are also some Chinese medicines (such as Lianhua Qingwen), which we have not only done in vitro experiments, but also found in P3 laboratory (the third-level laboratory of biosafety protection) that their antiviral effect is not strong, but their anti-inflammatory performance is outstanding, and the relevant experimental results will be published soon. In addition, there is Xuebijing, a traditional Chinese medicine. Its main components include safflower, salvia miltiorrhiza, radix paeoniae rubra, etc. It is used to promote blood circulation and remove blood stasis, but it is also effective in the treatment of severe patients. We are summarizing the situation of these drugs.

　　10. The vaccine will not be on the market soon, and the vaccination depends on the situation.

　　Zhong Nanshan:Vaccine is very important to really end the epidemic. Now all countries are developing it at the fastest speed, but I don’t think it can be made in three or four months. In addition, according to the experience of fighting SARS, removing the intermediate host can also block the spread of the epidemic. At present, we are not clear about the transmission chain in Covid-19, and it is also important to cut it off after it is clear.Put all your hopes on the vaccine, and all other methods are negative. Moreover, after the vaccine comes out, it is impossible to be perfect at once. The susceptible population can be vaccinated, but it is not necessary for everyone to be vaccinated.

　　11. Group immunization is the most negative practice.

　　Zhong Nanshan:The most negative way to deal with the epidemic is the so-called "group immunity", which was the idea more than 100 years ago.At that time, human beings had no choice but to let the virus infect them, and those who survived the infection naturally got antibodies. I don’t agree to deal with Covid-19 in this way again. In the past 100 years, mankind has made great progress, and there are many ways to prevent it, so there is no need to use natural immunity or group immunity.

　　12. The most worth sharing experience of the "epidemic" in China War is execution.

　　Zhong Nanshan:China War "epidemic" mainly took two measures: first, blocked the outbreak area and blocked the spread; The second is grassroots group defense and group governance. Now there are two core points of prevention and control: one is to keep a distance, and the other is to wear a mask.

　　So,China’s most shareable experience is execution.. The medical level and technical strength of many countries are much higher than that of our country. The reason why we were caught off guard in the face of the epidemic was because we were not prepared mentally and did not take decisive measures, which led to the infection of many front-line medical personnel. Once this line of defense collapses, it is easy to get out of control.

　　Cctv newsRecently, in the "100-day action" of the national public security organs to crack down on public security in summer, the public security network security department made a decisive attack and quickly detected a number of cases of developing, producing, releasing, selling, downloading and using false epidemic prevention software, so as to eliminate relevant epidemic-related risks in time. The Ministry of Public Security announced three typical cases today.

　　In view of the recent online epidemic-related illegal and criminal activities, the Network Security Bureau of the Ministry of Public Security attached great importance to it, and deployed public security organs in Guangdong and other places to carry out in-depth investigations according to law. It was found that individual criminal suspects developed, produced, published and sold false epidemic prevention "big data travel cards" and "health codes" on the Internet to help others forge epidemic-related proof information and display it on the fake health code page of the cottage, so as to deceive epidemic prevention staff to check and seriously interfere with the epidemic prevention and control order. At present, the public security organs have arrested 12 false software developers and producers, and investigated and dealt with a number of false software downloads and users according to law.

　　The relevant person in charge of the Network Security Bureau of the Ministry of Public Security said that the public security organs will further promote the "100-day action" to crack down on public security in summer, always maintain a high-pressure situation against all kinds of online epidemic-related illegal and criminal activities, and resolutely safeguard the order of epidemic prevention and control and people’s lives and health. The public security organ suggested that the development, production, release, sale, download and use of false epidemic-related software not only seriously interfered with and disrupted the normal order of epidemic prevention and control, but also was suspected of committing crimes. Please raise the awareness of prevention and consciously resist illegal and criminal acts and jointly safeguard the order of epidemic prevention and control.

　　The public security organs severely cracked down on typical cases of illegal crimes such as developing, producing, publishing, selling, downloading and using false epidemic prevention software;

　　Case 1: Guangdong Zeng Moufei developed and produced false epidemic prevention itinerary card and health code software.

　　In July 2022, Guangdong public security organs cracked a case of developing and producing false epidemic prevention itinerary cards and health code software, arrested Zeng Moufei, the software maker, and investigated and dealt with more than 100 software buyers and users according to law. After investigation, Zeng Moufei developed and produced the above-mentioned false epidemic prevention itinerary card and health code software in order to avoid the restriction of nucleic acid detection and show off computer technology, and released it to the Internet platform for others to download, which seriously interfered with the epidemic prevention and control work in COVID-19. At present, the public security organs have filed a case against Zeng Moufei and taken criminal compulsory measures. The case is under further investigation.

　　Case 2: Guangdong Feng Mohao developed, produced and sold false health code software on the Internet.

　　In June 2022, Guangdong public security organs cracked a case of developing, producing and selling false health code software on the Internet, arrested software producer Feng Mohao, and investigated and dealt with more than 20 software buyers and users according to law. After investigation, Feng Mohao developed and produced false health code software for illegal gains, and uploaded it to the Internet platform for public sale, which seriously interfered with the epidemic prevention and control work in COVID-19. At present, the public security organs have filed a case against Feng Mohao and taken criminal compulsory measures. The case is under further investigation.

　　Case 3: Guangdong Wei Mouye and others installed and used false health codes.

　　In June 2022, Guangdong public security organs detected a case of installing and using a fake health code APP program to forge a health code, and arrested the installation and use personnel Wei Mouye and Wen Mouhui. After investigation, Wei Mouye and Wen Mouhui obtained the fake health code APP program from the Internet platform and installed it on their mobile phones, tampering with the travel card information and disturbing the epidemic prevention and control order in COVID-19. At present, the public security organs have imposed administrative warnings and penalties on Wei Mouye and Wen Mouhui according to law.

　　Cctv news: On July 8th, CCTV’s "International Sharp Review" broadcast a commentary entitled "The United States will lose five major potential benefits in launching a trade war", which was reprinted by many overseas media.

　　July 8-9, French LCF Radio Facebook account, Spanish Radio International website, Spanish Huaxia Voice Broadcasting WeChat subscription number, Italian Milan FM89.8 Radio website, Portuguese Iberian Media Group APP, Portuguese Lisbon Rainbow FM website, Brazil Rio Headline China Radio Website, Brazil Sao Paulo World China Radio Website, Turkish Economic Observer Network, Kazakhstan’s "Business News" official website, Jordan Global Radio Facebook account, Facebook account of FM102.9 radio station in Dakar, Senegal, Chinese PT portal, Chinese headline APP, Portuguese new newspaper APP (Facebook account, Twitter account), American International Daily, Nordic Times, Australian ACMEDIA, European Union Chinese website, West Africa online website, Japanese Chinese business network and many other overseas media have reprinted it. On July 9, Hong Kong Ta Kung Pao and Wen Wei Po also published this comment. The main reports are as follows:

　　China Central Radio and Television General Station published a commentary entitled "The United States will lose five major potential benefits when launching a trade war". The article pointed out that since March this year, the trade conflict between China and the United States has been ups and downs, and the Sino-US "trade war" has been shrouded, which has brought many uncertain risks to Sino-US relations and even the world economy. Once the trade war breaks out, both China and the United States will lose both sides, and they will lose huge benefits from five aspects. To think about the problem in a different way, if the two sides can turn hostilities into friendship, they may be able to create a "miracle" in the history of world trade through their joint efforts.

　　The article said that the United States will lose five major potential benefits by launching a trade war. First, it will deprive China and the United States of broad space for future cooperation. If the two countries continue to struggle with the traditional trade deficit and refuse to look forward and far, the prospect of promoting closer cooperation and integration between China and the United States will not exist. Second, it will make China and the United States lose the great benefits brought by the division of labor in the global industrial chain. Third, it will make the world lose the great historical opportunity of economic recovery and warming. According to the research of relevant institutions, if the trade conflict between China and the United States cannot be solved well, its impact will spread all over the world, and world trade will even drop by 40%. Fourth, it will make the international order and international rules formed over the years lose authority and binding, which will lead to chaos in the world economy. Fifth, the most important thing is that the United States will lose China’s huge market dividend. China’s market is developing rapidly. In 2017, the size of China’s market is equal to that of the United States, and China will soon become the largest market in the world. In the next five years, China’s import volume will increase by 10 trillion US dollars. The Sino-US trade war will make the United States lose China’s huge market dividend.

　　The article points out that if the United States can change its thinking, China and the United States can create a new "miracle" from five aspects. First, relax American exports of high-tech products. This alone can increase China’s imports by $100 billion. Second, jointly promote the digital economy. Third, we should accelerate the BIT negotiations. Fourth, strengthen cooperation in the Belt and Road Initiative. Fifth, promote the FTA between China and the United States. According to the research conclusion of Peterson Institute, the two sides can increase the trade volume by 500 billion US dollars.

　　"Fourteenth Five-Year Plan" for High-quality Development of Foreign Trade. pdf

　　On November 29th, 2004, the 8th China-ASEAN Leaders’ Meeting was held in Vientiane, Laos. Under the witness of Premier Wen Jiabao and the leaders of the 10 ASEAN countries, the Minister of Commerce and the economic ministers of the 10 ASEAN countries jointly signed the China-ASEAN Framework Agreement on Comprehensive Economic Cooperation and the Agreement on Trade in Goods. On July 20th this year, the tax reduction plan of China-ASEAN Free Trade Area, the core content of the Agreement on Trade in Goods, was fully launched. This marks that the Agreement on Trade in Goods has officially entered the implementation stage, and also marks that the construction process of China-ASEAN Free Trade Area has been fully kicked off. In order to make readers have a more comprehensive understanding of the contents of the Agreement on Trade in Goods, grasp the specific arrangements of the construction process of China-ASEAN Free Trade Area, and make good use of the opportunities that the Free Trade Area will bring, this paper makes a general introduction to the Agreement.

　　The Agreement on Trade in Goods is a legal document regulating the arrangement of tariff reduction and dealing with non-tariff measures in the trade in goods between China and ASEAN. It has 23 clauses and 3 annexes, mainly including tariff reduction and cancellation, revision of concessions, quantitative restrictions and non-tariff barriers, safeguard measures, accelerated implementation of commitments, general exceptions, security exceptions, institutional arrangements and deliberations.

　　I. Classification of Free Trade Zone Products

　　According to the Agreement on Trade in Goods, all products are divided into two categories: normal products and sensitive products, except for the early harvest products with tax reduction arrangements.

　　In normal products, products are divided into two categories: first-track products and second-track products. What they have in common is that the final tax rate should be zero, but the difference is that the second-track products can enjoy certain flexibility in the time of canceling tariffs. Among the sensitive products, according to the degree of sensitivity, the products are subdivided into general sensitive products and highly sensitive products. What they have in common is that the final tax rate may not be zero, but the difference is that the general sensitive products will reduce their tariffs to a relatively low level after a period of time, while the highly sensitive products will eventually retain relatively high tariffs.

　　The product classification of China-ASEAN Free Trade Area can be illustrated by the following table:

　　

　　Second, the tax reduction mode of normal products

　　The negotiation of goods trade in China-ASEAN Free Trade Area adopts a "negativelist" mode, and all products that are not included in the list of sensitive products are regarded as normal products. Therefore, under the framework of China-ASEAN Free Trade Area, most products are normal products.

　　The Agreement on Trade in Goods specifies in detail the mode of tariff reduction and elimination for normal products, among which the special and differential treatment for new ASEAN members is an important principle embodied in the Agreement. The main provisions are:

　　(1) Tax reduction steps: For China and six ASEAN countries (old ASEAN members, namely Brunei, Indonesia, Malaysia, the Philippines, Singapore and Thailand), the normal products will be reduced in July 2005, and the tariffs will be reduced once on January 1, 2007 and January 1, 2009 respectively, and the tariffs will be finally reduced to zero on January 1, 2010; For the new members of ASEAN (Cambodia, Laos, Myanmar and Vietnam), the tariff will be reduced from July 2005, and the tariff will be reduced on January 1st every year from 2006 to 2009, and the tariff will not be reduced in 2010, and the tariff will be reduced every two years from 2011, and the tariff will be reduced to zero by 2015.

　　(2) Starting tax rate for tax reduction: The Agreement on Trade in Goods classifies products according to their starting tax rate, and each category follows a certain tax reduction model, and finally the tariff is reduced to zero. Generally speaking, at present, products with higher tax rates have a larger tax reduction rate and a faster rate of reduction, while products with lower tariffs have a smaller tax reduction rate and a slower rate, which can ensure the steady tax reduction of all products. Compared with China and the old ASEAN members, the new ASEAN members have a finer product classification, a more gentle tax reduction, and a longer time from the beginning of tax reduction to the abolition of tariffs.

　　(III) Normal products on Track 2: The tax reduction mode of normal products on Track 2 is exactly the same as that of normal products on Track 1. The only difference is that when the tariff of normal products on Track 2 is reduced to below 5% according to the tax reduction mode, the tariff can be kept at no more than 5%, and it will be zero later than that of normal products on Track 1. For China and six ASEAN countries, the tariffs on normal products on Track 2 should be abolished on January 1, 2012, and for new ASEAN members, the tariffs on normal products on Track 2 should be abolished on January 1, 2018. However, there are certain restrictions on the number of track two products. The track two products of China and six ASEAN countries shall not exceed 150 six-digit tax items, and the new ASEAN members shall not exceed 250 six-digit tax items.

　　(four) the specific tax reduction model of normal products in various countries:

　　1. China and six ASEAN countries.

　　

　　2. Vietnam

　　

　　3. Cambodia, Laos and Myanmar

　　

　　To sum up, the tariffs on track one normal products of China and six ASEAN countries should be abolished on January 1, 2010, and the tariffs on track two normal products should be finally abolished before January 1, 2012. The tariffs on normal products of Track 1 of new ASEAN members should be abolished on January 1, 2015, and the tariffs on normal products of Track 2 should be finally abolished before January 1, 2018.

　　Tax reduction mode of sensitive products

　　(I) Types of Sensitive Products Sensitive products are products that need to be protected for the development of domestic industries. It has certain particularity, and it takes a long time to reduce taxes, and the final tax rate cannot be zero, but it should be kept at a certain tariff level. According to the Agreement on Trade in Goods, sensitive products can be divided into general sensitive products and highly sensitive products according to their sensitivity. China put forward a list of sensitive products for the ten ASEAN countries, which is also applicable to the ten countries; Ten ASEAN countries put forward their own lists of sensitive products for China, and the listed sensitive products are only applicable to China.

　　In China-ASEAN Free Trade Area, each party has put forward different sensitive products according to its own situation. China’s sensitive products mainly include rice, natural rubber, palm oil, some chemicals, digital TV, plates and paper products. ASEAN countries have put forward sensitive products such as rubber products, plastic products, ceramic products, some textiles and clothing, steel products, some household appliances, automobiles and motorcycles.

　　(II) Upper Limit of Sensitive Products According to the Agreement on Trade in Goods, sensitive products are subject to two indicators, namely, the number of tax items and the import amount. In other words, the number of sensitive products cannot exceed a certain tax item, and the import amount affected by sensitive products of one party cannot exceed a certain proportion of the total import of that party, but the agreement also makes special arrangements for new members of ASEAN. The upper limit of sensitive products in each country is as follows: 1. China and six ASEAN countries: the number shall not exceed 400 (six tax items), and the import value shall not exceed 10% of the total import value (based on the data in 2001).

　　2. Cambodia, Laos and Myanmar: The number does not exceed 500 (six tax items), and there is no import ceiling.

　　3. Vietnam: The number shall not exceed 500 (six-digit tax items), and there is no upper limit for import, but Vietnam shall reduce the tariffs on sensitive products to a certain extent within the specified time.

　　(III) Tax reduction mode of sensitive products Generally, the tax reduction mode of sensitive products is different from that of highly sensitive products. Generally, the final tax rate of sensitive products is lower than that of highly sensitive products because of their low sensitivity, but the number of highly sensitive products is also subject to certain constraints.

　　1. Tax reduction mode for general sensitive products: (1) China and six ASEAN countries: reduced to 20% on January 1, 2012, and further reduced to below 5% on January 1, 2018.

　　(2) Cambodia, Laos, Myanmar, and Vietnam: it was reduced to 20% on January 1, 2015, and further reduced to less than 5% on January 1, 2020.

　　2. Tax reduction mode of highly sensitive products: China and six ASEAN countries should reduce the tariff of highly sensitive products to less than 50% on January 1, 2015, but the number of highly sensitive products should not exceed 100 six-digit tax items.

　　The new ASEAN members should reduce the tariffs on highly sensitive products to less than 50% on January 1, 2018, but the number of highly sensitive products in Vietnam should not exceed 150 six-digit tariff items, and Cambodia, Laos and Myanmar should not exceed 150 six-digit tariff items.

　　Rules of origin

　　Rules of origin are the yardstick to determine the "identity" of products. The rules of origin of China-ASEAN Free Trade Area are based on "value-added standards". According to the Agreement on Trade in Goods, if the value-added of local processing of a product is not less than 40% of the total value of the product, the product can be considered as a product originating from China-ASEAN Free Trade Area and enjoy the preferential tax rate of the free trade area in import and export trade. Because the early harvest products are mainly agricultural products, the criterion of "complete acquisition" is basically adopted. A few products with special circumstances, such as textiles and wool products, adopt other methods of origin determination, such as processing procedures and tax number change.

　　At present, the certificate of origin of China-ASEAN Free Trade Area uses FormE, which is different from the format of WTO certificate of origin. In China, it is issued by the General Administration of Quality Supervision, Inspection and Quarantine and local inspection and quarantine departments. With this certificate, you can enjoy the preferential tariffs of China-ASEAN Free Trade Area at customs clearance.

　　safeguard measure

　　Trade remedy measures are the "safety valves" of import and export trade, mainly including anti-dumping, countervailing and safeguard measures. The Agreement on Trade in Goods stipulates that the anti-dumping and countervailing measures of China-ASEAN Free Trade Area shall be subject to the relevant provisions of WTO. However, in terms of safeguard measures, in order to ensure that their domestic industries are not seriously affected, the agreement stipulates safeguard measures for the free trade zone, allowing all parties to adopt them when necessary.

　　The main content of safeguard measures in China-ASEAN Free Trade Area is that when the domestic production department of a product suffers substantial damage or threat of material injury due to the surge of imports from within China-ASEAN Free Trade Area, a contracting party may initiate safeguard measures and raise tariffs on products from China-ASEAN Free Trade Area. However, in order to avoid abuse of safeguards, the agreement also stipulates the restrictive conditions for each party to use safeguards. First, as far as specific products are concerned, the time limit for the use of safeguard measures is within five years from the date when the product starts to reduce taxes to the date when the product reduces taxes; Second, one implementation period shall not exceed three years, and the extension period shall not exceed one year; Third, the tariff rate for implementing safeguard measures shall not be higher than the MFN tariff rate for this product when taking safeguard measures; Fourthly, FTZ safeguard measures should not be used at the same time as WTO safeguard measures. The formulation of these rules, on the one hand, ensures the right of members to use safeguard measures, on the other hand, maintains the normal trade order.

　　Quantitative restrictions and non-tariff barriers

　　According to the Agreement on Trade in Goods, each contracting party should not keep any quantitative restrictions, and non-WTO contracting parties should gradually lift their quantitative restrictions. At the same time, all parties should determine their remaining non-tariff barriers as soon as possible and gradually abolish them. This provision is of great significance to effectively ensure the degree of self-ownership of China-ASEAN Free Trade Area.

　　Recognize China’s market economy status

　　In Article 14 of the Agreement on Trade in Goods, the ten ASEAN countries explicitly recognized that China is a complete market economy, and promised not to apply Articles 15 (anti-dumping substitute pricing clause) and 16 (special safeguard measures clause) of the Protocol on People’s Republic of China (PRC)’s accession to the World Trade Organization and paragraph 242 (special textile safeguard clause) of the Report of the Working Party on China’s accession to the World Trade Organization to China. This provision is of special significance to China, which not only strives for a fair and just trade competition environment for Chinese enterprises in the free trade zone, but also plays a good exemplary role in promoting other countries in the world to recognize China’s market economy status.

　　Other issues

　　The Agreement on Trade in Goods stipulates that all parties shall abide by the relevant provisions of the WTO in terms of technical barriers to trade, sanitary and phytosanitary measures and intellectual property agreements. The provisions of WTO multilateral trade in goods that are not specifically mentioned or amended in other agreements shall be applicable to China-ASEAN Free Trade Area after being amended. The agreement also provides for transparency standards, accelerated tax reduction arrangements, general exceptions, security exceptions, and related procedures and institutional arrangements.

　　The Agreement on Trade in Goods is a landmark agreement between China and ASEAN. Its achievement and implementation laid the foundation and paved the way for the comprehensive construction of China-ASEAN Free Trade Area. We should fully understand this agreement, seize the new opportunities arising from the FTA, and make new efforts to deepen and develop mutually beneficial and win-win cooperation with ASEAN countries.

In the past two years, the state and local governments have issued a series of policies to support the power exchange mode, explicitly supporting the construction of power exchange stations and encouraging the separation of vehicles and electricity.

By the end of April 2021, there were 63,000 public charging stations and 870,000 public charging piles in China. The total number of power stations is about 650, of which Beijing accounts for 33%, Guangdong accounts for 16%, and Zhejiang, which ranks third, accounts for 8%, while the number of power stations in other provinces is very low.

It can be seen that the current situation of power exchange station in China is low in quantity and uneven in distribution, and it is only used as a supplementary means of charging mode at present.

Then, can the future power exchange mode develop rapidly and become the ultimate mode of electric vehicle power supply?

Advantages:

1. The separation of vehicle and electricity in power exchange mode can reduce the cost of car purchase. Consumers only buy electric cars, and the batteries are used by leasing.

2. The replaced storage battery can be charged during the low power consumption period, and the power consumption cost is low.

3. Changing the power solves the problems of long charging time and short driving range. The split-box power exchange technology adopted by Bertram Technology can complete the power exchange within 5 minutes; The chassis power exchange technology adopted by Weilai can complete the power exchange in 3 minutes, which greatly relieves the mileage anxiety of car owners.

4. The closed-loop management of battery is realized by changing power, and the battery life is improved. The maintenance, recovery and reuse of batteries are handled by power grid enterprises.

5. Change electric energy to improve the efficiency of operating vehicles.

Disadvantages:

1. The construction cost of power exchange station is high.

2. There are many kinds of batteries, and it is difficult to unify the specifications.

3. The battery performance is quite different.

4. There are security risks: whether the battery box is firmly combined with the car body, and whether the power supply and communication interface are reliable in the state of frequent power exchange are all risks in the power exchange mode.

From the perspective of investment cost, changing power stations > charging piles.

The investment cost of a power station is about 1.5 million to 4 million yuan, including fixed assets investment Q, site rental, personnel operation and maintenance, etc. Looking back at ordinary fast-charging piles, the cost of charging piles ranges from tens of thousands to hundreds of thousands according to the charging power. The slow filling pile is cheaper, usually it can be built within 10 thousand yuan, and it is small and convenient.

From the perspective of investment cost, the power exchange station is higher than the charging pile. This is also why the penetration rate of domestic charging piles is much higher than that of changing power stations.

From the point of use efficiency, changing power station > charging pile.

● The power changing time of the power changing station is about 5 minutes;

● The charging time of fast filling pile is 30-60 minutes (charging to 80%); Slow charging can be as long as several hours.

Compared with the refueling of traditional fuel vehicles, changing electricity is closer to refueling and more efficient in terms of use time. However, the actual charging time of the current fast-charging charging pile is related to the battery capacity (size), charging pile power (speed) and rate limit (protection) of the electric vehicle, and can not fully reach the rated power of the charging pile.

From the perspective of use cost, the power station is less than or equal to the charging pile.

In terms of the use cost of power exchange, taking Weilai as an example, the price of power exchange is 180 yuan, the battery capacity is 70Kwh, and the cruising range is about 420 kilometers, equivalent to 0.42 yuan per kilometer; Taking BAIC Q as an example, three electricity exchange packages were launched: package A is 432 yuan/1,200 kilometers; B Package 630 yuan /1800 km; C package 1020 yuan /3000 kilometers. It’s about 0.34 yuan per kilometer.

Generally, the battery capacity of electric vehicles is about 50Kwh, and the first charge (public) is about 1.5 yuan. The cost of fully charging is 75 yuan RMB, and the cruising range is about 300km, which is equivalent to about 0.25 RMB per kilometer. For drivers who make a living by operation and people whose expenses need to be controlled, the lower the price, the better. For people with relatively high incomes, it is almost negligible. However, although the difference between the two kinds of charging costs is nearly double, consumers’ perception is not obvious, and they can’t feel it in the short term, but many a mickle makes a mickle in the long run.

From the point of view of practical promotion and use, changing power station ≤ charging pile

Charging piles can appear in the form of "charging stations" or "single piles". For the site requirements, the DC pile is slightly larger, and less than 1 square meter is enough; AC installation can be divided into wall-mounted type and column type. The former is hung on the wall and does not occupy the floor area, while the latter has thin columns and hardly occupies the area.

The battery pack storage warehouse, mechanical installation arm and distribution system between the warehouse and the power station are needed in the power station. Even if it is streamlined, it needs to "occupy a lot of territory."

In addition, both the power station and the charging pile will face the same kind of "waiting problem", that is, queuing to charge/change electricity. -At a site with a large flow of electric vehicles, the frequency of charging personnel is very high, and there will be phenomena such as queuing for charging piles and queuing for changing electricity. Charging piles take a long time and often wait for a long time; It is faster to change power at a power station, but if the battery in the library is not full, it still needs to wait for a long time.

Therefore, from the perspective of investors’ input, consumers’ experience and cost use, and manufacturers’ production standards, input and use costs have become a set of contradictions. According to market rules, the price should be higher under high input, but investors stand in the perspective of laying and promoting first, and take this high cost to consumers. Therefore, it has created a difficult situation that investors can’t make money in a short time, which further limits the pace for investors to continue to promote and expand. And manufacturing companies, including car companies and battery manufacturers, have different specifications without standard implementation, so there will be a kind of chaos: There are a lot of power stations, but the power stations that support my family can’t be used in your family.

However, taking history as a mirror, some good things are not popular at present, not because they are bad, but because of various reasons, such as current politics, cost, trust and so on, it may be possible to change time, a group of people and a place. From the perspective of user-oriented experience, people are often willing to "pay the price" and pay for it.

Popularization needs comprehensive development in investment cost performance, engineering feasibility, safety and controllability, and also needs policy support and assistance in standard formulation. It also needs users to experience low use cost, convenient use, safety and reliability to form trust.

Therefore, in a broad sense, it is difficult to promote the power exchange mode, but it can really solve the long-term problem of difficult charging; From the narrow sense of a single brand and model, the battery changing mode has indeed solved the problem of difficult/slow charging.

　　CCTV News:The suspect Saipov was born in Uzbekistan and immigrated to the United States in 2010 when he was 22 years old. Earlier, it was reported that it was hoped to find out whether he was related to terrorist organizations in Uzbekistan, but with more details disclosed, the American media believed that he was brainwashed by extremist organizations in the United States.

　　According to CNN, New York Governor Andrew Cuomo told the media that Saipov was influenced by extreme thoughts after immigrating to the United States. According to local media reports in New Jersey, Omar Mosque in New Jersey, where Saipov often attends worship, has been listed in the investigation catalogue by the new york police. The police believe that this mosque may be related to spreading extreme thoughts.

　　In an interview with Russian TV Today, Paul Valelli, a retired US military officer, said that he believed that Saipov was really influenced by radical thoughts after he came to the United States, but he believed that it was probably a mosque in Tampa, Florida that influenced Saipov.

　　Paul Valelli, a retired US military officer, said, "We know that Tampa has a very active mosque, where new jihadists are recruited, and we should close it as soon as possible.".

　　Colin Rowley, a former member of the Federal Bureau of Investigation, believes that this is mainly caused by the wrong policies of the United States. He believes that the United States has launched wars against Iraq, Syria, Libya and other countries, but in fact some of them have nothing to do with terrorism, on the contrary, they can play a buffer role, and what the United States has done has destroyed all this.

　　Colin Rowley, a former FBI member, said that everything was wrong, and everything was wrong after 9/11. Sixteen years later, we have become a sad country today, facing a permanent war on terrorism. I just want to remind everyone that we can quote George. W。 Bush promised to wipe out terrorists in those countries, so we don’t have to wipe them out in the United States, but this terrorist attack shows a rebound effect, and frankly it is counterproductive.

　　The suspect admitted to being bewitched by extremist organizations.

　　On the 1st local time, the suspect Saipov was charged with terrorism in Manhattan federal court. According to American media reports, it is not common in the United States to charge the perpetrators of vicious attacks with terrorism. According to American law, the crime of supporting terrorist organizations may be sentenced to life imprisonment, and the crime of intentional injury may be sentenced to death. During the police investigation, Saipov claimed that he was bewitched by extremist organizations.

　　Iron and steel industry is an important basic industry of national economy. Steel products are used in national defense security and people’s production and life, and weapons and equipment, energy production, transportation, machine building, housing construction and so on are inseparable from steel materials. At the same time, the steel industry is also a typical high energy consumption and high emission industry. Doing a good job in energy saving and emission reduction in the steel industry is of great significance for China to achieve the goal of "double carbon". The steel industry has a high degree of industrial correlation and a long supply chain. To promote the green and low-carbon development of the steel industry, efforts must be made from the whole chain of the steel industry chain and supply chain.

　　First, energy conservation and emission reduction in the steel industry chain and supply chain are the highlights of "carbon reduction"

　　(1) Steel production has a large carbon emission and high unit energy consumption.

　　The development stage of China’s economy, the characteristics of resource endowment, the heavy industrial structure and the energy structure dominated by fossil energy make China’s carbon emission base large and grow rapidly. Global Energy Internet Development Cooperation Organization "China2030Peak carbon dioxide emissions Research Report years ago shows that,2019In, China’s total social carbon emissions were about105100 million tons, of which carbon emissions from energy activities are about98Billions of tons, accounting for a proportion87%. In the carbon emission structure in the field of energy activities, the proportion of carbon emissions in the field of energy production and transformation and the field of energy terminal consumption is respectively47%and53%The steel industry is the industry with the largest carbon emission in the field of energy terminal consumption, accounting for the carbon emission in the field of energy activities.17%, much higher than the second and third building materials (8%) and chemical industry (6%) industry.2017China’s steel emissions per ton in.2Tons of carbon dioxide, far higher than the international advanced level.2018In, the comprehensive energy consumption per ton of steel in key large and medium-sized iron and steel enterprises in China reached.555Kilogram standard coal/Tons, much higher than Germany.251Kilogram standard coal/Tons, USA276Kilogram standard coal/Tons. It can be seen that the carbon emissions from steel production account for the largest proportion in the field of energy consumption, while the unit energy consumption is high, which is far from the international advanced level.

　　(B) steel logistics, transport links, carbon emissions.

　　At present, China has built the most complete steel industry system in the global industrial chain, effectively supporting the steel demand of downstream industries and the steady and rapid development of the national economy, and the steel output is continuous.25Ranked first in the world in, resulting in a huge amount of logistics. The main reason for the large carbon emission of logistics in China’s steel industry is that it is influenced by resource endowment. In the transportation of raw materials, due to the shortage of domestic natural mineral resources, especially high-grade mineral resources, steel raw materials rely on imports, resulting in long-distance transportation. Second, it is influenced by the layout of the steel industry. Domestic raw materials are mainly transported from the north to the south, which makes the transportation distance of raw materials involving iron ore, coking coal and other bulk materials longer. In the transportation of finished products, due to the large number, high dispersion and wide distribution of iron and steel enterprises in China, the layout of production areas is far from the consumer market, which makes the finished products need large-scale and long-distance transportation. The long-term demand in the southeast coastal areas, especially in the Pearl River Delta region, is large, and the production capacity in the Bohai Rim region needs to flow to the south. Third, it is influenced by production technology. China’s iron and steel production is mainly based on long-flow technology, and the transshipment in the factory is complicated. Generally speaking, the annual output of crude steel is up to.10100 million tons, the corresponding flow is about100100 million tons, of which four are transported outside the factory and six are transported inside the factory. Fourth, it is influenced by the mode of steel transportation. Transportation is the second largest field of energy consumption and carbon emission in China. Among them, the energy consumption of highways is the largest, and the energy consumption accounts for the total amount in the transportation field.83%Waterway is the second, and railway is the cleanest and low-carbon mode of transportation, and its energy consumption accounts for the total amount of transportation.3%. Road transportation is widely used in China’s steel logistics, which inevitably produces a lot of carbon emissions. Therefore, the iron and steel industry is influenced by many factors, such as resource endowment, production layout, technology and transportation mode, with high output, large logistics volume and huge carbon emissions.

　　Second, the steel industry must take effective measures to reduce carbon emissions.

　　(A) the establishment of carbon emission accounting system, to guide the industry carbon emission reduction.

　　Carbon trading is a transaction that takes carbon dioxide emission rights as a commodity, thus forming carbon dioxide emission rights.2011In, the pilot project of carbon emissions trading in China started.2013The first carbon emission trading platform started trading in Shenzhen in 2006. Since then, Beijing, Tianjin, Shanghai, Guangdong, Hubei, Chongqing and other provinces and cities have successively launched pilot carbon emission trading. this yearsevenmoon16The national carbon emissions trading market opened on June. Because the power generation industry is in the field of energy production and conversion with the largest carbon emission in the whole society, it is first included in the national carbon emission trading market.

　　In order to achieve the goal of "double carbon", the steel industry, as the industry with the largest carbon emission in the field of energy terminal consumption, is the key area of carbon control management, and will be included in the national carbon emission trading market in the future, so as to promote the transformation of steel production enterprises to clean production and reduce carbon emissions. Therefore, it is urgent for iron and steel enterprises to develop carbon emission accounting standard system, carbon control organization system and personnel training, so as to establish carbon emission accounting system in iron and steel industry and lay the foundation for carbon quota allocation and carbon emission trading system implementation.

　　(B) the implementation of steel production process transformation, reduce carbon emissions in production.

　　The 14th Five-Year Plan proposes to promote the clean and efficient utilization of fossil energy such as coal, and promote the green transformation of steel, petrochemical, building materials and other industries. Global Energy Internet Development Cooperation Organization "China2030Years ago, the peak carbon dioxide emissions Research Report put forward that to realize peak carbon dioxide emissions, it is necessary to "change the energy production mode with clean substitution and change the energy use mode with electric energy substitution".

　　The technological transformation of green steel production includes electric furnace steelmaking and hydrogen energy steelmaking. Electric furnace steelmaking is the main way to promote the substitution of electric energy, with scrap steel as the main raw material and electricity as the main energy source. This method has low energy consumption, low emissions and obvious advantages in energy saving and emission reduction. At present, the proportion of electric furnace steelmaking in China is only9%The proportion of electric furnace steelmaking in the United States and the European Union reached respectively.62%、40%. At present, the development conditions of electric furnace steelmaking are mature, energy saving and environmental protection. China should adopt lower carbon electric furnace steelmaking to reduce carbon emissions in steel production. Hydrogen energy steelmaking is beneficial for hydrogen to replace carbon monoxide as reducing agent, and there is no carbon dioxide emission in the reduction process, which can realize complete decarbonization of steel production and is the future development direction.

　　(C) steel logistics to green transformation, reducing carbon emissions in the steel supply chain

　　Iron and steel logistics should achieve green development by changing the mode of transportation, developing multimodal transport and developing smart transportation. The first is to change the mode of transportation. On the one hand, it is to promote "replacing oil with electricity" and promote enterprises to use new energy vehicles for road transportation. At present, China’s new energy vehicle industry is leading the world, new technologies are constantly emerging, the cost of lithium batteries is declining, and hydrogen energy technology is gradually mature and applied, which has the advantage of developing new energy vehicles; On the other hand, we should change from road transportation to cleaner railway transportation, reduce the proportion of road transportation, increase the proportion of railway transportation, speed up the construction of freight railway, solve the "last mile" problem and attract enterprises to choose railway transportation. In the 14th Five-Year Plan, it is proposed to speed up the transportation of bulk goods and medium and long-distance goods by "revolving iron" and "revolving water". Secondly, develop multimodal transport, strengthen infrastructure construction, multimodal transport station construction, logistics park construction and so on. Finally, it is necessary to develop intelligent transportation. First, it is necessary to develop autonomous driving technology. According to the research of the Ministry of Transport, self-driving cars can save fuel more than human driving.12%It is more energy-saving and environmentally friendly. At present, China’s autonomous driving technology is developing rapidly, and the conditions for popularization and application are basically available; The second is to build an information platform to promote the development of shared transportation mode and improve the pendulum of logistics, and realize real-time data exchange and information sharing through the information platform to improve logistics efficiency.

　　Third, the implementation of carbon emission reduction measures in the steel industry has a huge impact on costs.

　　(A) The steel industry carbon emissions accounting system needs to increase investment.According to the requirements of the Tenth Five-Year Plan, it is necessary to promote the market-oriented trading of carbon emission rights. The investment in carbon market construction is not only the investment in carbon emission system construction, but also the investment in various supporting measures within enterprises. The construction of carbon emission accounting system in iron and steel industry needs a lot of people, money and materials.

　　(2) The carbon emission cost of steel production is on the rise.Judging from the spot trading market of carbon emission quotas in the past few years, the overall trend of most trading markets is that the total transaction amount is on the rise and the average transaction price is on the rise. This shows that the transaction cost of carbon emissions of substandard enterprises will gradually increase. According to the transaction data published by Guangzhou Carbon Emissions Exchange,2015Annual turnover11399.2Ten thousand yuan is far below2020Annual turnover83454.15Ten thousand yuan, the average transaction price2020Annual25.58Yuan Dynasty (1206-1368)/Tons higher than2015Annual16.38Yuan Dynasty (1206-1368)/Tons.Judging from the national carbon market transaction data released by Shanghai Stock Exchange, the first month of market opening (sevenmoon16Solsticesevenmoon30Date) Monthly turnover of listed agreement transactions505.2Ten thousand tons,Highest transaction price61.07Yuan Dynasty (1206-1368)/Average transaction price per ton and month51.86Yuan Dynasty (1206-1368)/Tons, much higher than the transaction price at the time of the pilot.In addition, EU carbon emission quota trading data shows that,2018The annual average closing price is17.45euro/Tons,2019The annual average closing price is24.91euro/Tons.As can be seen from the carbon emissions trading between China and the EUThe transaction price keeps rising, and the carbon emission cost of substandard enterprises keeps increasing.

　　(C) Road transportation of steel logistics needs to pay a price for carbon emissions."Double Integral" in Automobile IndustryThe policy (namely "Measures for Parallel Management of Average Fuel Consumption of Passenger Car Enterprises and New Energy Vehicle Points") stipulates that the average fuel consumption of passenger car enterprises will generate positive points when it is lower than the standard value, and negative points when it is higher than the standard value. The integral trading market is a free trading market, and the price at the highest point of each integral can reach.3000Yuan. Changan automobile2020The annual expenses for solving the problem of substandard points are as high as.7.4100 million yuan. Weilai automobile is at2019Obtained in 200810Ten thousand points in2020Sold and brought in the second half of 20081.2Net income of 100 million yuan.

　　(D) Steel production needs to pay more for technological transformation.The technological transformation of green steel production includes electric furnace steelmaking and hydrogen energy steelmaking. In the short term, technological research and development and technological transformation need constant cost investment. In the long run, it will reduce carbon emissions and reduce carbon emission costs.

　　(E) The green development of steel logistics needs a lot of capital investment.It is necessary to realize green logistics by changing the mode of transportation, developing multimodal transport and developing smart transportation, and the transformation of related modes of transportation, infrastructure construction and logistics informatization construction all require a lot of capital investment. In the short term, it will bring a large increase in costs, but in the long term, it will bring about a reduction in carbon emissions and an improvement in logistics efficiency in the steel supply chain, thus reducing the logistics costs of the steel industry. In order to achieve the goal of "double carbon", the steel industry should actively explore the countermeasures to reduce costs and increase efficiency. Incorporate the cost of green development resources and environment into the cost accounting system. To achieve green management, reduce energy intensity and reduce carbon emissions, it needs to pay a lot of resources and environmental costs. Therefore, it is necessary to consider the resources and environmental costs into the overall cost of the steel supply chain and abandon the previous cost accounting methods that only account for manufacturing and logistics costs. Based on a comprehensive understanding of the overall cost of the iron and steel industry chain and supply chain, this paper systematically analyzes the influence of various factors on its cost with detailed cost data, and puts forward the countermeasures to realize the green development of the iron and steel industry to reduce costs and increase efficiency. At the same time, we should actively study measures such as changing industrial layout to improve industrial concentration, optimizing product structure to improve added value of products, changing traditional management concepts, adopting short-distance multimodal transport, improving production and transportation efficiency by means of informationization and digitalization, and improving the recycling of solid gas waste gas from steel production, so as to reduce the cost of steel industry chain and supply chain and promote the healthy and sustainable development of steel industry.

Network security refers to the ability to take necessary measures to prevent attacks, intrusions, interference, destruction and illegal use of the network and accidents, so that the network is in a stable and reliable operation state, and to ensure the integrity, confidentiality and availability of network data.

In today’s era, network security and informatization have an impact on many fields of a country, and network security has become an important part of national security. Without network security, there will be no national security, no stable economic and social operation, and it is difficult to protect the interests of the broad masses of the people. From a global perspective, the threats and risks of network security are becoming increasingly prominent, and they have penetrated into political, economic, cultural, social, ecological, national defense and other fields. Network security has become one of the most complex, realistic and severe non-traditional security problems facing our country.

To correctly establish the concept of network security, we must clearly understand the main characteristics of network security:

First, network security is holistic rather than fragmented.In the information age, network security has a close relationship with national security and many other aspects of security.

Second, network security is dynamic rather than static.The network has become highly interrelated and interdependent, and the threat sources and attack methods of network security are constantly changing, so it is necessary to establish a dynamic and comprehensive protection concept.

Third, network security is open rather than closed.Only based on the open environment, strengthening foreign exchanges, cooperation, interaction and games, and absorbing advanced technologies, will the level of network security be continuously improved.

Fourth, network security is relative rather than absolute.There is no absolute security, we should base ourselves on the basic national conditions to ensure security and avoid pursuing absolute security regardless of cost.

Fifth, network security is common rather than isolated.Network security is for the people, and network security depends on the people. Maintaining network security is the common responsibility of the whole society, which requires the joint participation of the government, enterprises, social organizations and the majority of netizens to build a network security defense line.

In daily work

If you don’t pay attention to the correct use of the net

Recently, Ne Zha, an animated film with high reputation, released the manuscript of character setting again, showing the audience the multi-version design concept maps of characters such as Ao Bing, Shen Gongbao, Taiyi Zhenren, Li Jing, Yin Fu, etc., in addition to the hundred-version Nezha. Since its release, the film has broken many records and won the support and recognition of countless audiences. At the box office, the film won the single-day box office champion for 18 consecutive days, breaking 3.6 billion, ranking fifth in the total box office list of China film history. Although it was only released in the mainland, it became the highest-grossing non-Hollywood animated film in the world. In terms of the number of people watching movies, the total number of people watching movies has exceeded 100 million, making it the third movie with 100 million people watching movies and the first animated movie with 100 million people in China film market. In word of mouth, it has been ranked as Top1 in the same period and has become the highest-rated animated film in the past 30 years. Up to now, the film Ne Zha has been on the hot search for nearly 70 times, which has been hotly debated by the whole people.

"Never forgets anything" role design, high standard, "sound first, then shape" and intentional dubbing

The film’s praise and recognition can’t be separated from the director jiaozi and his team’s efforts in characterization. It can be seen from this manuscript of character setting that apart from the 100-edition Nezha design, all the characters, including Ao Bing, Shen Gongbao and Li Jing, have gone through many versions of attempts and efforts to select the most suitable characters. It is reported that director jiaozi revealed that the role image of the film was jointly participated by many excellent designers, and it took more than a year to finalize and strive for perfection. In addition, each character also pursues the most unique effect in personality setting. For example, the two roles of Li Jing and Mrs. Yin in the film were initially divided into "extroversion" and "introversion", but this has never been able to "poke" the director jiaozi’s heart. After many attempts, the director jiaozi chose to switch their personalities, which led to Li Jing, who broke through the traditional "strict father" and loved her son deeply, and Mrs. Yin, who changed her previous husband and taught her children and was independent and courageous, which left a deep impression on the audience and was hotly debated.

In addition to the character image and personality setting, the film Ne Zha also made a lot of efforts in the process of character production. In order to match the role and dubbing, director jiaozi spent more than a year searching for the most suitable dubbing team. At the same time, the film adopts a rare process of dubbing first and then making. The dubbing actor imagines dubbing according to the story content without filming, and finally the animator makes animation according to the dubbing picture. Although this dubbing change has doubled the production time, it has also achieved a more realistic dubbing effect. Jiaozi, the director, said that every character was created with the aim of making the audience "unforgettable", hoping that a series of intentions, such as design, dubbing and production, would make the audience really like every "flesh-and-blood" character.

Tens of millions of viewers helped director Guo Man of Conscience draw every poster that broke 100 million yuan.

With only one mainland market, the film Ne Zha has successfully topped the list of non-Hollywood animated films with the highest box office in the world. The outstanding achievements of the film so far are closely related to every audience behind it who helps the growth of high-quality domestic animation. After thousands of advanced screenings in the country, the audience gave full praise to the film on the platform, and independently created fan paintings, handicrafts, expression packs and other "brain-opening" fan works to express their love for the film. After the official release, some loyal audiences actively interacted with Guan Wei every day, brushing five or even more films, and supporting Guo Man with actions; Millions of viewers even made various types of new content in the form of Nezha’s imitation makeup and Nezha’s dubbing, which helped the film spread. The number of related videos played exceeded 15 billion times, setting off several rounds of Nezha craze.

With the help and support of millions of viewers, the film Ne Zha not only broke the box office record of 1.53 billion animated films held by Zootopia for three years, but also broke the box office record of 3.6 billion, ranking in the Top5 of the total box office list of film history. In the face of the support and love of the audience all the way, director jiaozi expressed his gratitude by hand-painting the poster of Billion Dollars. At present, director jiaozi has painted 36 billion-dollar posters in 18 days. Each billion-dollar poster has expanded the content of the film twice in the form of a "small theater", which is full of heart. The director bluntly said that the achievements made by the film were completely unexpected at the beginning, and he was very grateful to the audience for their tolerance and love for Nezha. It is pressure and motivation to get so many compliments since the release, and I will "go all out" to make the next better work and give back to the audience.

As the first domestic animated film of IMAX, Ne Zha was jointly launched by Striped House Film (Big Fish Begonia), Cocoa Bean Animation (Fight, Fight a Big Watermelon) and October Culture (Return of the Great Sage). The film is being shown all over the country.
