The film "Nine Sisters" released the ultimate preview. Light comedy depicts the construction of new countryside.


1905 movie network news Recently, the premiere of a realistic film focusing on the digital economy to help rural revitalization was held in Beijing. The film is produced by Wang Hongxu, produced by Zhang Shuming, directed by Wei Qing, co-directed by Li Qi, co-written by Min Yan and Bai Tiejun, and co-starred by,, Gao Fang, Hu Qiusheng,, and so on. All the masters made their debut at the premiere conference, and the old leaders of the film and television industry, old-timers, related propaganda and cultural industry management departments and institutions, many actors, producers, directors and other stars came to the scene one after another.

 

Director Wei Qing re-directed the theme comedy to describe the construction of new countryside.

The final trailer of "Nine Sisters" was broadcast live at the press conference, and it was officially announced that the film will be released in the national cinema on January 9. Directed by Wei Qing, a veteran director, the film is adapted from the novel Jiumei Village written by Min Yan, a Heilongjiang writer, and written by Min Yan and Bai Tiejun. It tells the touching story of Jin Jiumei, a grassroots cadre of party member in northeast rural areas, and Aivi Lu, the first secretary of poverty alleviation in the village, leading the villagers to help agriculture through e-commerce and realize rural economic revitalization.

Different from other main melody movies, Nine Sisters is relaxed and funny although it is a new rural theme style. Director Wei Qing once directed masterpieces of realistic themes such as The Three Gorges Family, My Folks and My Brothers, and now he directs the main theme movies, with a more varied style. In this regard, Wei Dao said at the scene that the original intention of "Nine Sisters" was to present the centenary of the founding of the Party, and the style of light comedy was more helpful for the film to be loved by the audience. "The" 14th Five-Year Plan for China Film Development "issued by the State Film Bureau mentioned that the new mainstream films should focus on telling the story of China, shaping the image of China, carrying forward the spirit of China, and fully demonstrating cultural self-confidence with innovative expressions. Nine Sisters’ light comedy style is an innovation in the expression of new mainstream movies. In 2021, three domestic films ranked among the top ten in the global box office list, with two main themes and a comedy, and Nine Sisters combined the main theme and light comedy elements. I believe that the film will also be loved by mainstream audiences after its release. "

 

Undertake "Storm" and extend it to Shibadong Village to witness a glorious century.

In the final trailer released on the spot, some highlights of the film were also exposed in advance: The plot of Nine Sisters inherited the story background of the classic old film Storm during the land reform period and some relationships of characters, and continued to the new era and new countryside. After the poverty alleviation, party member Jin Jiumei innovatively used e-commerce to help farmers and led the villagers to common prosperity, and the plot of the film also extended to the 18-hole village, the first place to fight poverty.


As the location where the film was filmed and the film story took place, the Propaganda Department of Heilongjiang Provincial Party Committee attached great importance to the film "Nine Sisters", and the leaders of relevant departments also attended the film premiere ceremony, bringing greetings and expectations from the black land, and delivered a speech: "Jiumei Village in the film, like our first village of land reform, was once poor and white, but now it has achieved great changes in the countryside through storms. Promoting rural revitalization and building a beautiful China can’t be separated from the leaders of grassroots party organizations like Jiumei who set an example first and are brave in pioneering, struggling and dedication. In the new century, the journey is long, only struggle! Let’s go forward and create more brilliant glory! "

 

poplarTongshuGuo Jiaming unveiled the e-commerce live broadcast chaos and made his debut after the Golden Rooster Award.

"Nine Sisters" co-starred by powerful actors Tongshu Yang, Guo Jiaming, Gao Fang, Hu Qiusheng, Ma Shuchao and Liuyi Cheng, aiming at the e-commerce industry for the first time, revealing the chaos of e-commerce live broadcast with goods on a large scale. Jin Jiumei, the village party secretary played by Tongshu Yang, temporarily replaced Zhao Xiaoxue, the twin sister, to bring goods live, and witnessed all kinds of shady scenes such as brushing tickets behind the live broadcast, shoddy and shoddy products, and water army control and evaluation. This plot is simply a prophecy of the recent rollover of an e-commerce anchor in real life. Tongshu Yang has appeared in many hit dramas, such as The Supreme Beauty, Hanwu the Great, etc., and the paranoid mother played in In the Name of Family and Psychologist is particularly impressive. This time, there are two roles in the film, one is a village party secretary who can do justice, and the other is a fashionable and beautiful female anchor, whose image is extremely subversive. Guo Jiaming, the leading actor, has cooperated with and participated in the hit dramas Anjia and Shangyang Fu respectively, and also participated in the drama Glory and Dream, a major revolutionary historical theme. This time, he plays Aivi Lu, the resident poverty alleviation secretary, in Nine Sisters, and Jin Jiumei, the village party secretary played by Tongshu Yang, help farmers through e-commerce, and jointly lead Jiumei Village to common prosperity. Tongshu Yang attended the Youth Film Festival in Sichuan, and Guo Jiaming was recording a new album. Both of them regretted their absence at the same time, but they also connected the crew to wish the film conference a complete success.

Starring Gao Fang made her debut at the press conference at the age of 82. She has participated in well-received works such as Poems of Daming Palace and April Day on Earth, and her new film won the best small and medium-sized feature film award at the just-concluded 34th Golden Rooster Award. Gao Fang revealed at the scene that he played Yang Jiumei, the first generation party secretary of Jiumei Village, in the movie, which symbolizes the inheritance of economy, culture and responsibility with Jin Jiumei. "Both Zhao Lihua in Fish under the Ice and Yang Jiumei in Jiumei are my favorite roles. Thanks to the movie "Nine Sisters", let me show a different side. " There are also old actors, such as Hu Qiusheng, Ma Shuchao and Liuyi Cheng, whose roles and images in the film are very subversive, and they become the jokes of the film. Many old actors supported the scene, which made the texture of the film soar.

 

Good voiceShedanPassionate singing theme song Sun Bayi praised brilliant China

At the premiere conference, "Good Voice of China" Xie Dan passionately sang the theme song "I am You", which was written by director Wei Qing, "Pentium blood, unchanged genes, relay transmission." "Burning youth is endless, illuminating the new century … …” The lyrics reproduce the scene and determination of communist party people in the new era, such as Jiumei, who are committed to building a new countryside. Xie Dan also exposed himself as the role of Liu Xiangqin in the film, which was his first show on the big screen and his role was quite joyful.


Sun Bayi, a post-90s hip-hop singer, sang the movie propaganda song "Brilliant China", and lyrics such as "To create great historical achievements, the Party and the people should depend on each other, so that we can supplement rich spiritual food and look forward to the future" perfectly match the theme of the movie "Nine Sisters" focusing on rural revitalization. This song was praised by Guan Wei of "Liyuan Fan Group" because of the theme of positive energy and the new style of post-90 s hip-hop singers represented by Sun Bayi.

 

The word-of-mouth of the screening field continues to ferment. God predicts that the e-commerce anchor will turn into a bright spot.

"Nine Sisters" received rave reviews in the previous "national tour screening of wonderful films", and was once again unanimously affirmed by many experts and scholars from the industry, academia and critics at the expert observation seminar held in Beijing recently.


At the premiere of the day, a number of big names in the industry once again appeared at the premiere of Nine Sisters, and participated in the premiere viewing after the press conference, and interacted with the film creator with many audiences. Famous film critics greatly praised the combination of the film and the current hot spots, and thought that Nine Sisters profoundly presented the chaos such as pit fees and false bills for e-commerce live broadcast, and "God predicted" the standardization and rectification of e-commerce platform and live broadcast. The famous screenwriter affirmed the creative content and form of the film, saying that Nine Sisters has the shadow of Italian impromptu comedy. Especially in the second half of the film, as the sister of the village party secretary, she fought back against e-commerce bosses and loan sharks with courage and knowledge, which made the whole film jump out of the trap of simple pan-entertainment and pure comedy skills.

Help you dig out the "feeding" diet food for health.

  Recently, some media reported that online celebrity weight loss coffee cost 8 yuan, but it sold for 298 yuan. What is even more exasperating, however, is that coffee is actually a diet drug that was withdrawn from the market 10 years ago — — Sibutramine!

  It’s almost the season of revealing meat, and it’s not too late to lose weight. Have you ever been tempted by those advertising slogans that advertise that you can lose weight quickly, burn fat instantly and lose 30 pounds a month? Pharmacists are here to remind you that those slimming foods such as slimming tea, weight loss coffee, and fat-burning capsules sold illegally are likely to contain drugs added illegally, which pose a health threat to the body. Don’t blind your eyes to all kinds of fancy weight-loss products, otherwise it is very likely that the more you lose weight, the worse your body will be.

  What kind of "ghost" is sibutramine

  Searching for "sibutramine" in Baidu, I found that sibutramine was added to many so-called diet foods. For example, "fat-burning slimming capsules", fruit and vegetable drinks (solid drinks) and fruit and vegetable slices with slimming effect.

  Sibutramine is a central weight-loss drug, which can act on the central system, by inhibiting the reuptake of neurotransmitters such as norepinephrine, 5- hydroxytryptamine and dopamine in the body, so as to suppress appetite and reduce food intake to achieve the purpose of weight loss.

  In 1997, it was approved for obesity in the United States, and it became a weight loss star for a while, so it was listed in China in 2000. After listing, China’s ADR center also monitored some adverse reactions, mainly headache, dry mouth, insomnia, dizziness and so on. In fact, it may not only affect the digestive system, nervous system, central and peripheral nervous system, cardiovascular system, etc., leading to endocrine and metabolic disorders, mental stress, sleep disorders and so on. But the most serious is the risk of myocardial infarction, stroke, cardiac arrest and so on, especially for patients with heart diseases such as coronary heart disease, arrhythmia, or already suffering from cerebrovascular diseases, the risk of cardiovascular and cerebrovascular accidents is higher.

  In view of the fact that sibutramine may increase cardiovascular adverse events after marketing, in 2002, the European Union launched a large-scale clinical study on the influence of sibutramine on cardiovascular safety after marketing, which was called "Sibutramine Cardiovascular Terminal Test", including the participation of many countries and regions such as the European Union and Australia. The research results published in 2010 show that the use of this drug can increase the serious cardiovascular risk. Thus, since 2010, the United States, the European Union and China have successively withdrawn sibutramine from the market.

  Those "ingredients" lurking in diet foods

  At present, some illegal sales of slimming tea and weight loss coffee claim that the products are very safe while promoting slimming, which makes many consumers put down their defenses. But in fact, these weight-loss products are likely to have serious health risks. Because products that are generally claimed to have the effect of fast weight loss, in order to make consumers lose weight, it is very likely that some drugs will be added illegally, mainly in these categories:

  The most common way is to add appetite suppressants such as sibutramine, fenfluramine and its derivatives. These drugs mainly act on the central system of the brain to "pretend" to be full, reduce appetite and lose weight, but long-term use may affect the function of the heart and lungs, and cause symptoms such as palpitation and dyspnea, and increase the risk of pulmonary hypertension, myocardial infarction and cardiac arrest.

  Add some laxatives such as phenolphthalein tablets (guide tablets), bisacodyl, etc. Take bisacodyl as an example, it is an irritating laxative, but long-term use may lead to chronic diarrhea, hypokalemia, secondary aldosteronism, and even metabolic alkalosis, myasthenia, renal tubular injury and so on.

  Add some drugs to increase energy consumption, such as levothyroxine sodium, ephedrine, pseudoephedrine, theophylline, and diuretics such as furosemide and bumetanide. These drugs seem to "lose weight" by increasing energy metabolism and discharging more water, but in fact they may only lose some water.

  More importantly, taking these drugs without knowing it may bring harm to the body. For example, taking levothyroxine sodium for a long time may lead to drug-induced hyperthyroidism, and symptoms such as palpitation, emaciation and exophthalmos may occur. Excessive use of ephedrine, pseudoephedrine and theophylline may cause arrhythmia, anxiety and myocardial infarction, and excessive use of diuretics may cause electrolyte disorders such as low potassium and sodium.

  Other added drugs and some other drugs have also been detected in weight loss products, including fluoxetine and sildenafil. Many illegal weight-loss products contain not only one illegally added drug, but also two or more.

  Pharmacists give you a prescription for healthy weight loss.

  So is there a "safe" diet pill that allows us to reduce the meat easily? The answer is: not really. There is no product that claims to be safe to lose weight. No weight loss product is effective and has no side effects. Only a healthy diet plus adequate and moderate exercise is the safest and most effective way to lose weight. Here are three tips for losing weight safely.

  Before you lose weight, calculate your BMI index. The specific algorithm is to divide your weight (kg) by the square of your height (m). If it is less than 24kg/m2, you don’t need to lose weight. If you are not satisfied with your body shape, you can shape it through fitness. If it is between 24 and 24-28 kg/m2, it is overweight; Above 28 kg/m2, you are obese, and you need to reduce it if you are overweight or obese.

  It is suggested that only by adhering to a scientific lifestyle for a long time can we maintain our weight and reduce the rebound. Friends who need to lose weight and want to lose weight can go to the nutrition department of the hospital, ask a professional dietitian to give an individualized recipe, and then choose the exercise that they like relatively and suit them, and insist on exercising for a certain time every day.

  If you need help with drugs, you can choose orlistat. At present, in China, the only drug with obesity treatment indications and approved by National Medical Products Administration is orlistat. However, orlistat itself has some adverse reactions, such as oily stool, increased stool frequency, abdominal pain and flatulence, which may also lead to liver injury, so please use it under the guidance of a doctor or pharmacist.

  In addition, if you have diabetes at the same time, you can also choose hypoglycemic drugs, such as liraglutide, dulaglutide, exenatide, etc. For example, liraglutide has also been approved in the United States to assist patients with BMI above 27kg/m2 to lose weight. In addition, some drugs such as Dapagliflozin and Kaglinide can reduce blood sugar and weight at the same time.

  Although everyone loves beauty, the road to losing weight is long and difficult, and there is really no shortcut. Scientific weight loss is the king.

The evolution of the crime of cracking down on online game plug-in crime

The evolution of the crime of cracking down on online game plug-in crime

Some netizens in Zhihu asked the author: Does it constitute a crime of illegal business operation to use game AIDS like keyboard and mouse to practice online games? "A few months ago, a friend was detained for 30 days for illegal business operations and fined hundreds of thousands because he used game scripts to practice games. His game script is similar to the color recognition of the key wizard+simulation of the mouse and keyboard, developed by himself, without modifying the game client, so it should not belong to the plug-in. But one of the crimes of illegal business operation is illegal publications. His software is for personal use and has not been disseminated. I wonder if it’s really illegal? Suppose the software he uses is copyrighted? Is the situation different again? The key wizard has copyright. What’s more, JC seized all his dozens of computers without showing any documents, and searched his room. Is this in line with the rules? If this kind of case goes to court, what are the chances of conviction? I have consulted many cases, and it seems that there are only cases with plug-ins. "

The author’s answer to this: There is no official explanation for the definition of plug-in in China at present. My understanding is the cheating software of online games. For the conviction of plug-in, it mainly depends on what kind of legal relationship plug-in infringes. If it is convicted of illegal business operation, the court thinks that online games can only be operated with a license, and plug-ins operate without a license. If the crime of destroying the computer information system is determined, the court thinks that the operation of plug-ins destroys the communication between the server and the client of the online game company, resulting in the unstable operation of the server. If the crime of copyright infringement is determined, it is that the court thinks that the program of the game software is copied by the plug-in (many times this copy is actually just a call, but sometimes the court judge may not know the difference. )

In this case, if the plug-in is just a mouse and keyboard wizard, the crime of destroying computer information system and the crime of infringing copyright cannot be applied to crack down, and the only thing the court can decide is the crime of illegal business operation. But I think that criminal punishment involves people’s right to life freedom and needs to be treated very seriously. Although the plug-in industry has done great harm to the online game industry, cracking down on plug-in crimes should also comply with the relevant provisions of the Criminal Law. If the plug-in has little damage to online games, it should not be cracked down according to crimes, that is, it does not constitute a crime. The following is a paper I recently published in China Intellectual Property Magazine, which specifically discusses the advantages and disadvantages of various charges of plug-in crimes in China.

Since Shanda Network Company introduced Legend from South Korea in 2001 and became a hit, the online game industry has gradually developed into one of the most profitable industries in the domestic Internet, and has created many richest people in China, such as Chen Tianqiao and Ding Lei. However, with the development of online games, various black industrial chains around the industry have also risen rapidly, among which plug-ins that help players cheat in games are the most headache for game companies.

As far as I know during my work in an online game company, the essence of plug-in is game cheating software, which is named because it is attached to game software at runtime. Plug-ins have the following disadvantages: cheaters’ bad money drives out good money, defeats fair gamers in the game and undermines the fairness of the game; Plug-ins increase the burden on the server, forcing operators to increase the purchase of servers and bandwidth, thus raising costs and may lead to unstable server operation; Plug-ins enable players to quickly complete the tasks in the game, abnormally increase the consumption speed of game content, and make game companies have to invest a lot of human resources to increase the development of new game content. Although it can’t be ruled out that some plug-ins are developed for the shortcomings of game software, most plug-ins do destroy the user experience of the game, increase the development and operation costs of the game company and endanger the stable operation of the game.

In China, plug-in has become an industry. For any slightly popular game, R&D teams will be responsible for developing the corresponding plug-in programs, and there will be special teams to operate and sell plug-ins. There are also professional "gold-playing" companies that specialize in "gold-playing" in the game, which use a large number of plug-in programs to earn game coins, experience values, etc. and sell them to other players. It is no exaggeration to say that the whole plug-in industry is a cancer parasitic on the online game industry, and their existence has seriously damaged the development of the online game industry.

However, how to crack down on plug-ins has always been a headache for major game companies. Plug-in operators make full use of the anonymity of the Internet, the limited jurisdiction of governments in the Internet environment, and the characteristics that online payment circumvents traditional payment channels. The operating domain name and server of plug-in software are usually foreign, and the accounts used for collecting money are usually personal accounts. Even if game companies can’t contact plug-in developers, they can only see the instant messaging accounts of plug-in operators and sellers.

In this case, if the game company conducts a civil lawsuit against the plug-in operator, it will first encounter the problem of unknown subject. In many cases, the name of the defendant is unknown; Secondly, even if we know the name of the plug-in operator or even the company that runs the plug-in, we don’t know anything about their property. The plug-in operator knows that plug-in is illegal, so the bank account used for operation will generally transfer the funds in the account to other personal accounts or relatives and friends accounts in a short period of time, so even if the civil lawsuit wins, it is difficult for the game company to execute its property. Third, civil prosecution can only attack the sales and operation links of plug-in industry, but not the development links. In the final analysis, the plug-in industry is a part of the underground economy, and it is not strong enough to crack down on it with civil litigation.

Since civil litigation is not feasible, many online game companies can only seek criminal means. However, the online game industry itself is a new industry, and the plug-in behavior that destroys it is unprecedented. Whether the plug-in behavior constitutes a crime or not, and what charges should be dealt with if it constitutes a crime, in practice, major game companies and legal practitioners have been groping for many years, and have gone through three stages: the crime of illegal business operation, the crime of copyright infringement and the crime of destroying computer information systems.

The first stage is the crime of illegal business operation.

The criminal object of the crime of illegal business operation is the market order, especially the market management system in which the state restricts the sale and purchase of goods and business licenses. The corresponding legal provision is Article 225 of the Criminal Law. As the operation of online games belongs to value-added telecommunications services according to the provisions of the Telecommunications Regulations, it is necessary to apply for the business license of value-added telecommunications services at the Ministry of Industry and Information Technology. The Interim Provisions on the Administration of Internet Publishing promulgated in 2001 and the Interim Provisions on the Administration of Internet Culture promulgated by the Ministry of Culture in 2003 also stipulate that the publication and operation of online games require the prior administrative license of the General Administration of Press and Publication or local press and publication bureaus and the Ministry of Culture. Therefore, online games are an area that needs a government license to operate, and some game companies try to report the behavior of developing and operating plug-ins as illegal operations.

The specific basis is Article 11 of the Supreme People’s Court’s Interpretation on Several Issues Concerning the Specific Application of Laws in the Trial of Criminal Cases of Illegal Publications, which was promulgated in 1998: "In violation of state regulations, publishing, printing, copying and distributing other illegal publications that seriously endanger social order and disrupt market order other than those stipulated in Articles 1 to 10 of this Interpretation, if the circumstances are serious, they shall be convicted and punished for the crime of illegal business operation in accordance with Article 225, paragraph 3, of the Criminal Law."

The first domestic plug-in case: Tan, former vice president of Rising, illegally operated the plug-in case. Since June 2004, the defendant talked about a certain person and others developing 007 plug-in software for Legend 3. And set up a website to promote and provide download services, and also wholesale and retail plug-in software cards, with a business volume of more than two million yuan.

After trial, the court of first instance held that the defendant talked about a certain person who, for the purpose of making profits, carried out operating Internet information services without approval, violated the regulations of the state on publishing management, used Internet websites to carry out illegal Internet publishing activities, published and distributed illegal Internet publications, infringed on the legitimate rights and interests of copyright owners, publishing institutions and game consumers, and disrupted the normal order of Internet game publishing and operation, and the circumstances were particularly serious, which constituted the crime of illegal business operation. After the original public prosecution agency filed a protest, the court of second instance held that the actions of the three defendants had constituted the crime of illegal business operation, and the circumstances of the crime were particularly serious. They were sentenced to a fixed-term imprisonment of 6 years (two years and six months in the first instance) and fined 500,000 yuan.

After the verdict was made, major online game companies in China began to report plug-in crimes on the grounds of suspected illegal business. However, from the legal point of view, the crime of illegal business operation infringes on the national market management system that restricts the sale and purchase of goods and business licenses. If operating plug-in software constitutes a crime, it needs to be certified for illegal publications. In early cases, the General Administration of Press and Publication identified many plug-in programs as illegal publications, and every plug-in program identified by it was treated as a criminal case of illegal business operation. However, traditional illegal publications generally contain pornographic or reactionary content, while plug-in programs only help players cheat in online games, and basically do not contain pornographic or reactionary content. Moreover, the crime of illegal business operation is considered as "pocket crime" in practice. Therefore, there are also objections in theory and academic circles to cracking down on business plug-in with this crime. At the same time, after identifying a number of plug-ins as illegal publications, the General Administration of Press and Publication began to reduce the identification of illegal publications, so in recent years, there are few practices.

Second, the stage of copyright infringement crime.

After cracking down on plug-ins through the crime of illegal business operation for a period of time, judicial organs in some areas began to try to crack down on plug-ins by using the crime of copyright infringement stipulated in Article 217 of the Criminal Law. The subjective aspect of the crime of copyright infringement requires copying and distributing works that others enjoy copyright without permission for profit.

The reason for attacking plug-ins with the crime of copyright infringement is that the development and operators of plug-ins copy some programs in online game software for profit. Because the profit of plug-in is millions, it is not difficult to reach the bottom line of the crime amount punishment.

Case: Defendant Zhang et al. made and sold the plug-in software for Adventure Island game operated by Shanda Network, and the profit was huge, which was later captured. The court submitted the software to Shanghai Oriental Computer Judicial Appraisal Institute for identification, and confirmed that the plug-in invaded the online game client program of Adventure Island by means of memory hook, gained control over the memory address and data modification of the program, and called and copied the data naming and data copying of 124 client software function data of Adventure Island.

The court held that the copyright of online game software of Adventure Island should be protected by Chinese laws. Defendant Zhang and others jointly copied and distributed the online game software client program of Adventure Island for profit without the permission of the copyright owner, and the amount of illegal business was huge, and the circumstances were particularly serious, which constituted a crime of copyright infringement according to the provisions of Article 217 of the Criminal Law of People’s Republic of China (PRC). In the end, Zhang was sentenced to five years in prison, and the other defendants were also sentenced to fixed-term imprisonment.

However, the author has personal objection to punishing plug-ins for this crime: if the plug-in operator is to be deemed as a crime, it is obvious that there must be unauthorized copying of computer software. The plug-in production operators do not need to copy online game software in their operations. Even if it is to be copied, not all the game client software is copied by plug-ins, but only a few applications involving data modification; And in many cases, some programs in the software are copied between the memory and hard disk of the same computer. This behavior is essentially not copying, but calling. The online game client software called by the plug-in program is generally a legal version downloaded by the player from the official website of the game. Obviously, this is different from the original intention of the criminal law to crack down on copying-to crack down on the spread of unauthorized software. Therefore, the behavior of operating plug-ins does not meet the constitutive requirements of copying computer software without permission in the objective aspect of crime. Although the case was later included in the top ten typical cases of intellectual property protection in Shanghai in 2010, in practice, there are not many cases in which the crime of copyright infringement is used to crack down on plug-in crimes, and the cases retrieved by the author are basically applied by the courts in Shanghai.

Crime of destroying computer information system.

Although the previous charges against plug-ins are a bit problematic, with the strengthening of legislation, the online game industry finally found a suitable charge against plug-ins in 2011. Article 286 of China’s Criminal Law stipulates that anyone who, in violation of state regulations, deletes, modifies, adds or interferes with the functions of the computer information system, thus causing the computer information system to fail to operate normally, and the consequences are serious, shall be sentenced to fixed-term imprisonment of not more than five years or criminal detention; If the consequences are especially serious, they shall be sentenced to fixed-term imprisonment of not less than five years. Whoever, in violation of state regulations, deletes, modifies or adds data and applications stored, processed or transmitted in computer information systems, if the consequences are serious, shall be punished in accordance with the provisions of the preceding paragraph. However, because there are no applicable standards with serious consequences and particularly serious consequences, this provision is rarely used to crack down on plug-in crimes.

In September, 2011, the Supreme People’s Court and the Supreme People’s Procuratorate jointly promulgated and implemented the Interpretation on Several Issues Concerning the Application of Laws in Handling Criminal Cases Endangering the Security of Computer Information Systems, which has a clear quantitative index for the criminal consequences of destroying computer information systems, and greatly reduced the difficulty of cracking down on plug-in crimes.

Case: Su Mou and others modified the data of the online game server of Tianlong Babu through their own computer knowledge and software, implemented plug-in behavior, illegally swiped virtual currency and virtual items, and sold them online for profit. Their behavior caused a large number of abnormal accounts in the online game of Tianlong Babu to continue swiping gold coins in the game, which caused a serious impact on the virtual economic system in the game, causing the game network to be seriously blocked, and the players could not log in normally, so the operating company could only stop and maintain the server.

According to the trial of the People’s Court of Linghe District, Jinzhou City, the defendants Su Mou, Lin Mou, Zhou Mou, Li Mou, Pang Mou and others used plug-in software to modify the data of the online game server of Tianlong Babu, which caused the computer information system of Beijing Changyou Times Digital Technology Co., Ltd. to fail to operate normally, with serious consequences, clear criminal facts and reliable and sufficient evidence. In the first instance, the defendants Su Mou, Lin Mou, Zhou Mou, Li Mou and Pang Mou were sentenced to one year and one month in prison for the crime of destroying the computer information system, and the other defendants were sentenced to six months in prison, suspended for one year, and all the illegal gains and tools of the defendants were confiscated.

This case is different from the traditional case of developing and selling plug-in software. The traditional case of plug-in attacks the behavior of developing or selling plug-in, while this case attacks the gold-playing company that uses plug-in to "play gold" in the game and sell it to other players. There has been a great controversy in the industry about whether the use of plug-ins by gold-playing companies constitutes a crime. A typical case is that the Nanjing court ruled that the person in charge of a gold-playing company committed a crime with the crime of illegal business operation. However, there is obviously no national license restriction on the use of plug-ins to play gold in the game. Therefore, the case is very controversial. However, it is obviously more appropriate to use the crime of destroying computer information system to deal with the large-scale use of plug-ins to make money, because the large-scale use of plug-ins by plug-ins to make money may also lead to the criminal consequences that computer information systems cannot operate normally.

Finally, criminal punishment involves people’s right to life freedom and needs to be treated very seriously. Although the plug-in industry has done great harm to the online game industry, cracking down on plug-in crimes should also comply with the relevant provisions of the Criminal Law. From the point of view of the evolution of the charges against plug-in as a high-tech crime, although there are disputes at every stage in the whole process, it is indeed developing in a reasonable and perfect direction. Therefore, it can be seen that although there is a certain lag in the development of law, it will not lag behind for too long.

The dilemma of "deindustrialization" in Europe has intensified.

  Since the outbreak of the conflict between Russia and Ukraine, Europe has followed the United States to impose several rounds of severe sanctions on Russia. Recently, a number of foreign media reported that the spillover effects of sanctions against Russia caused high inflation in Europe and the economy continued to be under pressure. Europe is increasingly worried about the problems brought by sanctions.

  find it difficult to advance or to retreat―be in a dilemma/plight

  According to today’s Russian International News Agency, Uwe Schultz, a German parliamentarian, recently warned that the EU’s largest economy is facing further economic recession and "de-industrialization" due to the EU’s sanctions against Russia. Schultz issued a statement on the website of his political party, saying that economic sanctions against Russia have hit the German economy hard. Schultz said that the sanctions against Russia and the economic measures taken by the German ruling Coalition are leading Germany directly to "de-industrialization", "the economic prospect of Germany in 2023 is disappointing" and "the poor performance of the automobile industry continues to lead to a decline in manufacturing output". Stefan Wolff, president of the German Federation of Employers’ Associations in the Metal and Electrical Engineering Industry, also believes that the German economy is no longer competitive and is expected to fall into recession in the second half of this year.

  According to preliminary data released by Eurostat on July 31, Germany’s GDP in the second quarter of this year increased by zero month-on-month, which was less than the market’s previous expectation of 0.1%. According to the latest forecast of the International Monetary Fund, the German economy will shrink by 0.3% in 2023.

  Many European companies are also facing the negative impact of European sanctions against Russia. The Financial Times recently conducted a survey on the operating conditions of 600 large European enterprises, and the results showed that 176 of them lost more than 100 billion euros due to the reduction, sale or closure of their business in Russia. This figure does not include the losses caused by indirect factors such as rising energy prices and rising production costs caused by the Russian-Ukrainian conflict.

  According to statistics, before the outbreak of the conflict between Russia and Ukraine, more than 1,800 large enterprises in Europe had operations in Russia, and more than half of them still continue to operate in Russia. According to the analysis, many European enterprises are in a dilemma under the influence of European sanctions against Russia: on the one hand, leaving Russia will have a direct negative impact on their own operations, on the other hand, staying in Russia will face more and more political and economic risks.

  Since the outbreak of the conflict between Russia and Ukraine in February 2022, European countries have followed the United States to impose several rounds of sanctions on Russia. In May, the British government announced the expansion of sanctions against Russia, including punitive import tariffs on precious metals produced in Russia and export bans on certain British products. In June, the EU reached an agreement on the 11th round of sanctions against Russia, including measures aimed at cracking down on circumvention of existing sanctions. Russia retaliated against Europe by cutting fuel supply and implementing ruble settlement.

  "The impact of sanctions against Russia on European countries is not exactly the same, and two types of countries are the most affected: first, countries that are highly dependent on Russian energy, such as Hungary and other Central and Eastern European countries; Second, countries whose industrial structure is dominated by manufacturing and energy-intensive industries, such as Germany, Italy and other European manufacturing powers. " Yan Shaohua, an associate researcher at the China-EU Relations Research Center of the Institute of International Studies of Fudan University, said in an interview with this reporter.

  Fatal impact

  "In recent years, the European economy has been affected by the European sovereign debt crisis ‘ Sequela ’ The continuous influence of is in a slow recovery. After the outbreak of the Russian-Ukrainian conflict, this recovery process was disrupted. The biggest impact of sanctions against Russia on European countries is to aggravate Europe ‘ De-industrialization ’ Worried. " Zhang Jian, vice president and researcher of China Institute of Contemporary International Relations, told this reporter that German, Italian and other European countries have comparative advantages in the field of high-end manufacturing, and an important basis for this advantage is cheap natural gas from Russia. Nowadays, these European countries are bearing the cost of sanctions against Russia, that is, losing cheap Russian natural gas and having to purchase more expensive energy from other countries, which has led many European manufacturing enterprises, especially energy-intensive enterprises, to face rising production costs and be forced to cut production, stop production or move their production lines outside.

  Purchasing Managers’ Index (PMI) released by Standard & Poor’s Worldwide shows that in July, the manufacturing PMI in the euro zone dropped to 42.7, the lowest level since the outbreak of COVID-19. As a big European manufacturing country, Germany performed poorly, and its manufacturing PMI plummeted to 38.8 in July.

  The report of the United Nations Department of Economic and Social Affairs pointed out that high energy prices weakened the competitiveness of European energy-intensive industries, resulting in the loss of market share.

  The economic census report released by dihk this summer also shows that the fluctuation of energy and raw material prices is the biggest risk faced by German enterprises, among which 80% of energy-intensive enterprises list it as the number one risk. According to the report of "Credit Reform", a German credit agency, the number of German enterprises filing for bankruptcy in the first half of 2023 increased by 16.2% year-on-year. In addition, many enterprises plan or have begun to transfer their business to countries with relatively low energy. For example, dozens of enterprises, including Lufthansa and Siemens, are considering expanding production and increasing capital in the United States.

  "Affected by the COVID-19 epidemic, the European economy is already facing problems such as high inflation rate, high unemployment rate and broken supply chain, and sanctions against Russia have further aggravated these problems. From the production point of view, sanctions against Russia have led to the gradual energy development in Russia and Europe ‘ Decoupling ’ It is difficult for European countries to find a suitable alternative in a short time to make up for the loss of cheap energy in Russia, which makes the manufacturing cost rise sharply. From the perspective of consumption, energy shortage leads to soaring energy prices, which will inevitably affect commodity prices in European countries, thus pushing up inflation and increasing people’s living costs. " Yan Shaohua said.

  Some analysts pointed out that Russia is an important supplier of raw materials for high-end manufacturing in Europe. There are many links in the industrial chain of high-end manufacturing industry, and the supply chain is accurate and complex. The obstruction of the upstream link means the source fracture of the industrial chain and supply chain, which will have a fatal impact on the whole industry. Although Europe tries to avoid areas that will "jam its neck" in the process of sanctions against Russia, with Russia’s retaliatory countermeasures, Europe’s high-end manufacturing industry is in a passive position.

  snow plus frost—exacerbate

  Agence France-Presse reported that since the outbreak of the conflict between Russia and Ukraine, the EU has imposed unprecedented sanctions on Russia, but EU diplomats admit that the EU sanctions are close to the limit.

  "At present, there is little room for further escalation and overweight of European sanctions against Russia. However, in the short term, sanctions will continue and there is no room for manoeuvre. In this context, Europe’s next question is how to deal with the impact of sanctions on itself. Since the energy crisis last year, Europe has been looking for ways. The European Union has introduced a series of measures, on the one hand, to find energy suppliers that can replace Russia, on the other hand, to release ‘ Green agreement industry plan ’ Accelerate energy transformation and green development. " Yan Shaohua believes that with the relevant EU policies gradually playing a role, the pressure faced by EU countries in energy this year may be eased compared with last year, but the problem has not been fundamentally solved.

  Leonhard Birnbaum, CEO of Eon Energy Group, pointed out that the EU will change its energy structure and reduce its imports of Russian energy due to the conflict between Russia and Ukraine, and this trend will continue, so the energy crisis in Europe is far from over. "In the long run, because we can’t get cheap energy from Russian pipelines, it is expected that the price of natural gas will rise, which may be two to three times that of now." Leonhard Birnbaum said.

  According to the preliminary statistics released by Eurostat on July 31, after zero growth in the first quarter of this year, the euro zone economy grew by 0.3% in the second quarter. Analysts pointed out that although the euro zone economy has resumed growth, the risk of stagnant growth still exists due to factors such as high inflation, weak global demand and monetary tightening policy. Among the major economies in the euro zone, Germany and Italy continue to suffer from the shrinking demand for goods due to the larger manufacturing scale.

  "In the foreseeable future, it will be more difficult for the European economy to turn around. On the one hand, the energy security situation in Europe has not fundamentally improved, European manufactured goods have lost the Russian market, and the competitiveness of European products will continue to decline; On the other hand, the United States introduced the Inflation Reduction Act and the Chip and Science Act to attract European companies to invest in the United States, which will make the European economy worse. " According to Zhang Jian’s analysis, as the largest economy in the European Union, Germany has strong economic radiation, especially its close integration with the economies of neighboring countries. If Germany is affected by sanctions against Russia and its economic situation cannot be effectively improved, then in the next three to five years, Germany’s neighboring countries and even the entire euro zone economy will also encounter troubles, and the overall economic policy and political and social stability of the EU will be negatively affected.

  Some analysts pointed out that high-end manufacturing is the core of European real economy and one of the main engines leading European economic growth. If it is difficult for European countries to get through the obstruction of industrial chain and supply chain, it may be difficult to maintain their leading position in high-end manufacturing in the future. By then, Europe will not only face the problem of economic recession, but also be more difficult to achieve "strategic autonomy".

Take measures to promote the healthy consumption of food nutrition for urban and rural residents, focusing on three aspects.

CCTV News:According to the person in charge of the Ministry of Agriculture and Rural Affairs, at present, China’s per capita energy, protein and fat supply have exceeded the world average, but the situation of unbalanced and insufficient nutrition is more common, which can be summarized as "more" and "less".

"Too much" means eating too much vegetable oil. At present, the per capita cooking oil in China exceeds the recommended amount of scientific diet by more than 40%. "Less" means insufficient intake of healthy foods such as milk and dairy products, soybeans and bean products. At present, the annual consumption of milk per capita in China is only one-third of the world average and one-half of the average in Asia, far below 110— The recommended dietary amount of 183 kg, the intake of soybeans and bean products is lower than the recommended amount.

Three aspects focus on promoting healthy consumption of food nutrition for residents.

The relevant person in charge of the Ministry of Agriculture and Rural Affairs said that many measures will be taken to promote the healthy consumption of food nutrition for urban and rural residents, focusing on three aspects.

Lei Liugong, Director of Market and Information Department of Ministry of Agriculture and Rural Affairs:The Ministry of Agriculture and Rural Affairs, together with relevant departments, will coordinate the construction of a healthy China and a strong agricultural country, and take a series of measures to promote healthy consumption of nutrition with the goal of meeting the needs of people’s high-quality life and population’s high-quality development.

At the production end, we will further promote variety cultivation, quality improvement, brand building and standardized production, and increase the supply of green and high-quality products by developing new healthy and nutritious foods such as soy products and cheese, so as to enrich consumers’ dining tables. In terms of supervision, we should strengthen the supervision on the quality and safety of agricultural products, fully implement the certification system for edible agricultural products, and ensure the "safety" so that consumers can eat with confidence. In addition, around the key contents such as "reducing oil and increasing beans", we will strengthen the popularization of food nutrition science, guide urban and rural residents to adjust their eating habits and food structure, so that ordinary people can choose, eat and eat healthily.

From stumbling to counterattack all the way, the original "Fengyun" is such a satellite.

  Fengyun-4 Satellite Photo courtesy of China Aerospace Science and Technology Corporation No.8 Institute

  During the Tenth Five-Year Plan period, China plans to launch seven Fengyun meteorological satellites. By 2035, China’s meteorological comprehensive strength will reach the world advanced level, and meteorology will be deeply integrated into people’s livelihood security and industry development, and a meteorological power will be basically built. ]

  Start wechat, a lonely villain stares at the earth. The first complete photo of the Earth released by NASA to the world is called "Blue Marbles". It was shot by Apollo 17 astronauts, and the perspective was over the African continent.

  Whenever Chen Xiaojie, deputy director of the General Office of Meteorology and Environment of the Eighth Academy of China Aerospace Science and Technology Corporation and chief designer of Fengyun-4 satellite, opens WeChat, his thoughts will always fly to September 25, 2017 involuntarily.

  That day was the day when China’s new generation of geostationary orbit meteorological satellite Fengyun-4 A star was officially delivered and put into use, and the WeChat startup screen changed its face accordingly — — The image is still the blue earth, but the location of the exhibition has become the Eastern Hemisphere, and it was Fengyun No.4 A star that shot it.

  "The photo perspective is the earth observed from above China, and that feeling is very different." Chen Xiaojie has been deeply impressed by this.

  At the beginning of 1969, a rare freezing rain and snow disaster swept half of China. At that time, only the Soviet Union and the United States had meteorological satellites in the world. Although China can accept foreign satellite cloud picture, it is only a simple "black-and-white image", and it is impossible to mine the original data and retrieve various meteorological elements, so its application is greatly limited.

  On January 29, 1969, Premier Zhou Enlai put forward: "We should quickly change our backwardness and build our own meteorological satellite." In February 1970, Premier Zhou personally issued documents from the Central Committee of the Communist Party of China, the State Council and the Central Military Commission, and assigned the task of developing meteorological satellites. As a result, China’s meteorological satellite industry officially started.

  Up to now, China has successfully launched 17 Fengyun series meteorological satellites, and 7 of them are currently in orbit. These satellites, which are the most "aware of people’s warmth and coldness", observe the changes of the earth in space, prompting us to add clothes and umbrellas.

  According to the China Meteorological Bureau, China plans to launch Fengyun-4 B and Fengyun-3 E satellites in 2021, and seven Fengyun meteorological satellites are planned to be launched during the 14th Five-Year Plan period. "By 2035, China will establish a meteorological business system with accurate monitoring, accurate forecasting and fine service. The comprehensive meteorological strength will reach the world advanced level, and the meteorology will be deeply integrated into people’s livelihood security and industry development, and a meteorological power will be basically built." Zhuang Guotai, director of the bureau, revealed.

  The fate was ill-fated, and the first star "died" after 39 days of launch.

  On September 4th, 1988, Astrin Zhong, the chief designer of Fengyun-1 satellite, stood on the tower with a height of tens of meters, and his heart turned upside down.

  That was the day when China’s first Fengyun satellite was originally planned to be launched. However, after the commander issued the "5-hour preparation" instruction, the control center suddenly lost all the telemetry signals of the satellite and the launch was terminated.

  Ren Xinmin, chief designer of Fengyun-1 satellite project, ordered on-site inspection. Meng Zhizhong and Xu Fuxiang, then the chief designer of the attitude control system, climbed the tower with the test team and nervously performed "surgery" on the satellite. At this time, there are no guardrails around, and there are rockets filled with propellant under the satellite. Every movement should be careful.

  What makes Meng Zhizhong feel stressed is that the scheduled launch time is approaching, and the stations around the country are already ready, constantly calling for news; From Beijing to Shanghai and then to the launch center, soldiers were deployed on the communication lines along the way, and everyone was waiting for the news of the launch at their posts. The troubleshooting work on the tower is progressing slowly, and Meng Zhizhong is both anxious and guilty.

  It was not until the evening that the cause of the fault was finally found out. It was the CMOS circuit of the telemeter that had a "bolt lock" under certain circumstances. The test team took down the telemeter and repaired it overnight, and put it back on the satellite the next morning.

  Three days later, Fengyun-1 A, which took nearly 10 years to develop, was successfully launched, making China the third country in the world with polar-orbiting meteorological satellites. However, after just over a month, the accident happened again.

  On this day, the staff of the National Satellite Meteorological Center found that the received satellite cloud image gradually deviated, and finally only the arc of the earth could be seen. The satellite is out of control.

  Zou Jingmeng, then director of China Meteorological Bureau, asked eagerly: Is there any other way? Meng Zhizhong was speechless.

  Because there was no backup equipment installed, Fengyun-1 A star "died" in space in full view, only 39 days before its launch.

  A rare satellite ground rescue in the history of world space flight

  On September 3, 1990, Fengyun-1 B star was successfully launched. It can provide weather forecast for the 11th Asian Games in time, but after only ten days, it is abnormal.

  Scientific and technical personnel completed the repair in time, but found a thorny problem: the satellite did not carry out anti-radiation reinforcement in component selection and software design. This loophole exposed the computer circuit chip to the bombardment of high-energy particles in space, which easily led to the problem of single event overturning, which would lead to computer malfunction and attitude control system failure at any time.

  The loopholes cannot be filled, and the only way is to strengthen the monitoring of satellites and correct problems in time.

  Astrin Zhonghe and Xu Fuxiang led the scientific and technical personnel to be divided into two working groups, which were on duty in Xi ‘an Satellite TT&C Center in turn. They use the opportunity of the satellite crossing the border six times a day to monitor its on-orbit work.

  On February 14, 1991, in the New Year’s Eve, the satellite cloud picture suddenly distorted and rolled. In the next 75 days, the staff took turns on duty without interruption and began a rare satellite ground rescue operation in the history of world space. Like emergency doctors, they have revived Fengyun-1 B star again and again. However, frequent "operations" have greatly damaged the satellite’s vitality and greatly reduced its life.

  Eventually, Fengyun-1 B star worked intermittently until November 1992, and accumulated normal operation for 285 days in orbit, which failed to reach the design life index of one year.

  Academician Sun Jiadong, a meritorious scientist with two bombs and one satellite, has been with Fengyun for more than 40 years as the chief designer of Fengyun-2 satellite project. He once said: "I have been a chief satellite engineer in my life, and Fengyun-2 is the most unforgettable."

  In February 1994, China’s first geostationary orbit meteorological satellite — — Fengyun-2 01 came to xichang satellite launch center. After many tests, the satellite was successfully refueled and fitted with a solid apogee engine, only to be fully tested for the last time before the transition.

  On the morning of April 2, the test began. At about 10: 50, the solid apogee engine burned and exploded, and black smoke came out with red flames. The observation window glass was shattered and the power supply of the factory building was interrupted.

  This major accident claimed the life of an assembly worker and caused more than 30 test team members to be injured and hospitalized. Astronauts suffered a painful lesson because they did not understand the performance and danger of hydrazine fuel and ignored the requirements of anti-static and environmental temperature and humidity.

  Fengyun-1 star C made a beautiful "turnaround"

  Successive accidents have caused Fengyun satellite development to fall into a downturn. But the astronauts who fell again and again stood up stubbornly again and again. They compiled heavy lessons into a book and became a typical teaching material to guide the follow-up work.

  Meng Zhizhong was 60 years old when he was appointed to preside over the development of Fengyun-1 C star. The previous setbacks made him unwilling. He analyzed that the reason why Fengyun-1 A-Star and B-Star failed to complete their tasks was not that the performance indicators did not meet the requirements, but that they died halfway due to low reliability. Developing a long-term, reliable and stable operational meteorological satellite has become the common goal of the team.

  On May 10th, 1999, Fengyun-1 C star was successfully launched. This launch was later selected as one of the three major events in the last year of the 20th century in China, which was engraved on the China Millennium Monument. In August 2000, the World Meteorological Organization listed the satellite in the world operational meteorological satellite sequence.

  Fengyun-1 star C made a beautiful "turnaround". It has been running stably in orbit for 7 years, and is known as "the first long-lived satellite in sun-synchronous orbit", which has opened a new page in China’s meteorological satellite industry.

  Since then, Fengyun Satellite’s development has become smoother and smoother.

  In 2002, Fengyun-1 D star was launched, becoming one of the longest-lived remote sensing satellites in China. Fengyun-2 C satellite launched in 2004 was the most widely used operational satellite in China at that time, and was highly appraised by the World Meteorological Organization, and was listed as one of the important operational satellites of the global meteorological satellite observation network. From 2006 to 2014, China launched four Fengyun-2 series satellites, which provoked the burden of meteorological support for major national events.

  In 2008, on the eve of the opening of the Beijing Olympic Games, Fengyun-3, China’s second-generation sun-synchronous orbit meteorological satellite, was launched. Since then, Fengyun-3′ s B, C and D stars have been launched one after another, realizing the upgrading of Fengyun-1. They operate in a network with complementary functions, and realize the detection from two-dimensional imaging to three-dimensional detection, and from single optics to full-spectrum wide-spectrum detection, which greatly shortens the update time of global numerical weather forecast, prolongs the forecasting time and further improves the forecasting accuracy.

  In the international "dark war", one star does the work of two stars.

  On January 15, 2021, the price of Taihu short-legged vegetables in Shanghai vegetable market doubled compared with 10 days ago. The local media found that this has something to do with the recent cold wave. According to the forecast of the Meteorological Observatory, there was another cold wave on January 16, and the local vegetable supply unit deployed ahead of schedule to fully carry out the emergency supply work.

  Weather changes affect people’s clothing, travel and even all aspects of life. Tang Shihao, director of the Remote Sensing Application Office of the National Satellite Meteorological Center and chief designer of Fengyun Meteorological Satellite Application System, said that it is only one of Fengyun Satellite’s "basic skills" to provide support for accurately forecasting the cold wave and monitoring its development and influence.

  In particular, a new generation of geostationary meteorological satellites — — The successful launch of Fengyun-4 A satellite has made China’s meteorological satellite technology change from following and running in parallel to running in parallel and leading, which has further improved China’s meteorological comprehensive ability.

  Recalling the development and launch of Fengyun-4 A star, Chen Xiaojie felt like a fierce competition.

  In 2016, as if agreed in advance, the development of a new generation of geostationary meteorological satellites in China, the United States, Europe and Japan all reached a critical juncture, and everyone was secretly struggling.

  In addition to the fact that European satellites have not yet been launched for various reasons, in early November 2016, Japan took the lead in launching the "Himawari 9" satellite. This satellite adopts many American technologies and products and will replace the "Sunflower 8" previously launched by the country.

  On November 19th, a new generation of geostationary meteorological satellite GOES-R was launched. According to industry evaluation, compared with previous meteorological satellites, the leap brought by this satellite is like changing from black-and-white TV to high-definition color TV.

  On December 11th, China’s Fengyun-4 A star was launched.

  Chen Xiaojie said that Fengyun-4 A star not only leads the world in its comprehensive observation ability to the earth, but also is the first geostationary meteorological satellite in the world to realize the comprehensive observation of "multi-spectral two-dimensional imaging+hyperspectral three-dimensional detection+ultra-narrow-band lightning imaging" by a single satellite.

  In the past, the interference between vertical detection instruments and imaging observation instruments has always been an international problem. The previous practice in Europe was to put the two on two satellites respectively.

  Compared with international competitors, the performance of Fengyun-4 A star is not inferior. Some people describe this star as doing the work of two stars at the same time.

  According to Dong Yaohai, chief designer of Fengyun-4 satellite system, the satellite has realized the simultaneous operation of multiple loads with moving optical components through the self-developed SAST-5000 satellite platform, and all loads coexist harmoniously.

  The multi-channel scanning imaging radiometer carried by the satellite was the most advanced radiation imager for geostationary satellites in China at that time, which could scan the eastern hemisphere every 15 minutes with the highest spatial resolution of 500 meters. "The accuracy of 500 meters is equivalent to placing a few candles a few kilometers away for a geostationary orbit close to 36,000 kilometers high, and it can be seen clearly." Dong Yaohai said that this accuracy is equivalent to the GOES-R satellite launched by the United States at the same time.

  At the same time, the interferometric atmospheric vertical detector carried by Fengyun-4 A star can detect the atmosphere vertically; China’s first satellite-borne lightning imager can be used to stare at China and its surrounding areas with wide-angle lenses, and it can take 500 photos every second to record the frequency and intensity of lightning.

  Fifteen years later, meteorological comprehensive strength leads the world.

  Starting this year, Fengyun family will be "added".

  According to the China Meteorological Bureau, the second satellite of Fengyun-4 — — Fengyun-4 B star, the development work has been basically completed. According to the plan, it will be launched this year.

  The load of Fengyun-4 B star has been optimized. For example, multi-channel scanning imaging radiometer, some channels have been locally optimized; The spatial resolution of the atmospheric vertical detector has also been improved.

  At the same time, a fast imager has been added to this satellite, which can flexibly observe different areas according to instructions by adjusting the lens, and the resolution is the highest among the global geostationary meteorological satellites at present.

  Tang Shihao is looking forward to this. He said that at present, Fengyun-4 A star images China and its surrounding areas once every five minutes, with the highest resolution of 500 meters. Some weather phenomena with smaller scale and shorter duration may be missed. The fast imager carried by Fengyun-4 B star can image millions of square kilometers once a minute, with the highest resolution of about 250 meters, which has stronger monitoring ability for small and medium-sized weather systems.

  E-Star Fengyun-3, which China plans to launch this year, will be the world’s first meteorological satellite in the morning and evening orbit. At present, the global polar-orbiting meteorological satellites are all in the morning or afternoon orbit, which means that their observation period is in the morning or afternoon. The E-Star Fengyun-3 will be observed at dawn and dusk, which can make up for the current observation gap and improve the accuracy and timeliness of global numerical weather forecast.

  Tang Shihao introduced that after the E-Star Fengyun-3 and Fengyun-3 series satellites currently in orbit are networked, the daily observation time distribution will be more uniform, and the meteorological data of morning and evening time will be obtained. In addition, in the past, Fengyun satellite could only be observed by infrared and microwave instruments at night, while Fengyun-3 E-star was equipped with low-light-level observation equipment, which had the ability to observe visible light at night.

  The reporter learned from the China Meteorological Bureau that the Fengyun satellite planned to be launched in China during the "14th Five-Year Plan" period will further enrich its orbital types. For example, in the geostationary orbit, there will be Fengyun satellites with different orbital positions, which will be observed by optical and microwave means. In low orbit, in addition to the morning and afternoon orbit and the morning and dusk orbit, China will also launch precipitation satellites to the low inclination orbit, mainly to monitor the precipitation in low latitudes.

  Tang Shihao said that the development of Fengyun satellite in the future mainly includes improving the monitoring ability of atmospheric wind field, cloud and rain atmosphere and its vertical structure, improving monitoring accuracy and monitoring timeliness, and enhancing the cooperative mobile observation ability of satellites.

Experts on the Defence of Blue Sky (5) Dust is an important source of particulate matter, and control should be continuously strengthened.

  The causes, sources and control of heavy air pollution are one of the hot issues in society. During the Spring Festival and epidemic control, the National Joint Center for Air Pollution Prevention and Control thoroughly analyzed the characteristics and laws of the heavy pollution process, providing continuous scientific and technological support for winning the blue sky defense war in 2020. The National Joint Center for Air Pollution Prevention and Control has recently launched a series of expert interpretations, which we forwarded to further respond to public concerns. In this issue, experts from Nankai University and china environmental science Research Institute are invited to analyze and interpret the impact of dust on air pollution.
  1. Dust is atmospheric particulate matter (PM10And PM2.5Etc.).
  According to China’s Technical Code for Prevention and Control of Urban Dust Pollution (HJT393-2007), dust sources can be divided into four categories: road dust, construction dust, soil dust and yard dust. The research results of source inventory show that the emission of PM10 in Beijing-Tianjin-Hebei and the surrounding "2+26" cities reaches 1.7 million tons/year, and PM2.5It reaches 450,000 tons/year, of which roads and construction are the main sources of dust in most cities, and together they can account for more than 80% of the total dust emission. The results of urban particulate matter source analysis for many years also show that although dust has been controlled to some extent in recent years, the sharing rate of dust in most cities to PM2.5 concentration is still 15%~25%.
  Urban dust has the characteristics of uncertain source intensity, random emission, diverse emission locations and types. The impact of dust is mainly affected by two factors: one is the amount of particles (such as road dust load) and the physical properties of particles (such as water content) on the carrier (such as roads) carrying dust, and the other is the disturbance degree of human activities or natural forces. The more dust accumulated, the greater the disturbance, and the more serious the impact of dust. There are a lot of cars driving in the road environment, and human activities are very intense, so road dust is one of the most important sources of dust. But the problem is that our roads don’t produce much particulate matter, and the road dust is very high on most roads. Many roads have more than 10 grams/square meter of dust, and good roads only have 1-2 grams/square meter, or even lower. So where does the dust on the road mainly come from? The research results for many years show that road dust is closely related to the material transportation in the construction site. In addition to the dust pollution caused by various construction operations (especially ground-breaking operations), it is more important to have its "long chain" emission, that is, a construction site will cause a large area of dust pollution due to the transportation and scattering of various raw materials, earthwork and other materials. Therefore, construction and roads are important sources of dust, and are the focus of urban dust control.
  2. Changes in the activity level of dust-related pollution sources during the Spring Festival and the epidemic.
  According to the big data of construction machinery based on the Internet of Things, the average operating rate of construction machinery during the Spring Festival in 2020 was about 5%, and it was about 23% in the same period in 2019, and the operating rate of construction machinery decreased by 77% year-on-year. After the Spring Festival in 2020, affected by the epidemic (from the seventh day to the 23rd day of the first month), the operating rate of construction machinery did not gradually return to the pre-holiday level as in previous years, but the operating rate remained at around 7%, and it did not show signs of recovery until after the 24th day of the first month. This shows that there are fewer construction projects and fewer "direct sources" of construction dust.

  In addition, motor vehicle traffic is also significantly affected by the epidemic. In 2020, the cross-sectional traffic volume of passenger cars and trucks in the six provinces of Beijing, Tianjin and Lu Yu will be 50% and 53% respectively compared with last year. From the first day of the first month to the seventh day of the first month in 2019, the cross-section traffic volume increased rapidly from a low value, and the cross-section traffic volume on the seventh day of the first month has basically reached a normal level, while in the same period in 2020, the cross-section traffic volume has remained at a low level due to the epidemic situation. This shows that there are fewer cars on the road and fewer disturbances caused by human activities.

  3. The change of particulate pollution characteristics during the Spring Festival this year just shows the impact of dust.
  During the Spring Festival and the epidemic, the sources of dust have decreased, so let’s take a look at the corresponding changes in the characteristics of particulate pollution. For "2+26" cities, the whole year of PM in 20192.5/PM10The average ratio was 0.57, and it reached 0.77 in January 2020, up 10% from 0.7 in the same period of 2019. It even rose to 0.84 during the Spring Festival and the epidemic period, up 38% from 0.61 in the same period of 2019, and even reached 0.9 in some cities during the Spring Festival and the epidemic period.
  We know, PM10With PM2.5It is an inclusion relationship, and the ratio of the two can reflect the source and characteristics of particulate pollution to a certain extent. In more than 300 cities in China, the ratio is between 0.3 and 0.8. Generally speaking, the ratio will be higher in cities with higher level of urban dust management, usually around 0.7, or even up to 0.8. The proportion of cities with low level of urban dust management or affected by sandstorm is relatively low, which can reach about 0.3. Theoretically, it affects PM.2.5/PM10The main factors of the ratio include source composition and meteorological factors. In addition to the influence of meteorological factors such as static weather and high humidity conditions, the particle size distribution law of different source sources is very different. Such as PM in dust emission2.5It only accounts for about 5-10%, and the particulate matter emitted by motor vehicles can be considered as PM.2.5Organized emissions from industrial enterprises are also dominated by fine particles. That is to say, the higher the proportion of fine particles in particulate matter, the lower the proportion of coarse particles, indicating the lower the contribution of dust sources. On the other hand, the source analysis results of some cities show that the contribution rate of dust to PM2.5 in January 2020 is only 5%, which is a quarter of the usual state. Therefore, the recent changes in the characteristics of particulate pollution in Beijing, Tianjin and Hebei show that the sharp reduction of social activities during the Spring Festival and the epidemic has reduced the contribution of dust sources to particulate matter, which has reduced PM.10The concentration has obvious effect, and it also has some influence on reducing the concentration of PM2.5.
  4. Suggestions on dust pollution control
  Compared with other sources of particulate matter, the technical threshold of dust source prevention and control is not high, the cost is low, the effect is quick, and there is still a large controllable space. However, in view of the characteristics of dust sources, it is still difficult to have a set of technical systems such as emission standards, monitoring norms, treatment and evaluation like other source management, so there are still many difficulties in practical work. In practice, there is a common phenomenon that one pipe is effective and it will rebound as soon as it is loosened.
  We believe that management is the core, implementation is the key, infrastructure is the cornerstone and system is the guarantee in dust prevention and control. The first thing is to carry out education and technical training on dust pollution prevention and control for sanitation workers, construction site workers, front-line workers and managers of dust-prone industrial enterprises, so that dust prevention and control will become a spontaneous and conscious behavior of front-line personnel; Second, it is necessary to strengthen the global prevention and control of dust pollution, focusing on the urban-rural fringe, taking the urban built-up area as the standard, implementing urban and rural bare ground greening, and hardening the dirt roads in the urban-rural fringe and rural areas; Third, we should strengthen the whole process control of dust generation, transportation, stacking and unloading, optimize and improve the relevant assessment mechanism, and establish a public supervision mechanism; Fourth, we should establish and improve the index system and normalization evaluation mechanism of dust prevention and control in engineering construction site; Fifth, we must rely on advanced technical means to realize online monitoring and control of dust pollution and realize all-round control of dust pollution.
  China’s air pollution has gone from pollution source management to total amount management to current quality management, and pollution control has gone from single-source management to multi-source management to current multi-source and multi-pollutant collaborative management, so pollution prevention and control has embarked on a comprehensive, refined and scientific road. The same is true for dust prevention and control. We should not only pay attention to those visible construction sites and mounds, but also unswervingly follow the route of comprehensive prevention and control of multiple pollutants, pay attention to all sources that can produce dust, and carry out in-depth and meticulous control on pollution sources such as industry, coal burning and motor vehicles, so as to finally achieve the goal of comprehensive air quality standards.
