Sustained improvement shows resilience, and foreign trade can be expected to maintain stability and improve quality.

  Today’s editorial

  Special commentator of this newspaper

  Generally speaking, China’s foreign trade was more resilient in the first seven months, which laid a solid foundation for the stability and quality improvement of foreign trade throughout the year. With the continuous increase of macro-policy adjustment, a package of policies and measures has been accelerated to take effect, China’s main economic indicators have improved marginally, and the overall recovery of the national economy has accelerated. A stable and reliable industrial chain and supply chain, a huge market and domestic demand, and a new kinetic energy driven by innovation … … The fundamentals of China’s strong economic resilience, sufficient potential and long-term improvement have not changed, providing a good environmental support for foreign trade development.

  According to the latest data released by the General Administration of Customs, in the first seven months of this year, the total import and export value of China’s goods trade was 23.6 trillion yuan, an increase of 10.4% over the same period last year. Among them, the export was 13.37 trillion yuan, a year-on-year increase of 14.7%; Imports were 10.23 trillion yuan, a year-on-year increase of 5.3%; The trade surplus was 3.14 trillion yuan, an increase of 62.1%. Since the beginning of this year, in the face of the complicated and ever-changing international environment, China has effectively coordinated epidemic prevention and control and economic and social development, and foreign trade has overcome many adverse effects and achieved rapid growth.

  Stabilizing foreign trade and foreign investment is related to the overall economic situation and the overall employment situation. Especially under the background that the international environment is becoming more complicated and severe and some unexpected factors exceed expectations, stabilizing foreign trade has become an important support for China’s steady growth. From April, the growth rate of foreign trade dropped to 0.1%, and rebounded rapidly in May and June, reaching 9.5% and 14.3% respectively. The V-shaped recovery curve in the first half of the year showed the strong development resilience of China’s foreign trade. From the cumulative growth rate, the first seven months increased by 10.4% year-on-year; On a monthly basis, July increased by 16.6% year-on-year. Comparing a number of data, it is not difficult to find that the growth rate of foreign trade in July continued the good trend of continuous recovery. The growth rate continues to rise, and foreign trade continues to improve, indicating that China’s foreign trade has withstood the pressure and gradually returned to the development trend of strong strength and sufficient toughness.

  Open the door to the outside world and expand the space for foreign trade cooperation. Expanding openness and integration and achieving win-win cooperation are important magic weapons for China to stabilize foreign trade and foreign investment. From the implementation of the new version of the negative list of foreign investment access in the national and free trade pilot zones, the foreign investment market access will be further relaxed; To successfully hold the African Good Things Online Shopping Festival, buy in the BRICS and other activities; Then, carry out the law enforcement inspection of the Foreign Investment Law and urge the implementation of the national treatment for foreign-funded enterprises … … Since the beginning of this year, in the face of a more severe and complicated external environment, China has expanded its high-level opening to the outside world, promoted the steady development of foreign trade and foreign capital, stabilized its scale, improved its quality, promoted innovation, continuously released policy dividends, and continuously expanded the space for foreign trade and economic cooperation.

  In the first seven months, China’s import and export to major trading partners such as ASEAN, the European Union, the United States and South Korea maintained a growth momentum. Since the implementation of the Regional Comprehensive Economic Partnership Agreement (RCEP) this year, the trade dividend has been continuously released. In the same period, China’s import and export with countries along the Belt and Road and RCEP member countries increased by 19.8% and 7.5% respectively, further deepening regional economic interconnection and trade and investment cooperation, and providing new momentum for regional economic recovery and development.

  From hats and glasses to expand the market, to Tricholoma matsutake and honey pomelo for "fresh" export, and then to sweeping robots and solar cells for sale overseas … … The effective stimulation of the vitality of foreign trade subjects is also regarded as an important reason for promoting the sustained recovery of foreign trade growth. Since the beginning of this year, in order to help foreign trade enterprises solve the problems such as poor logistics, inefficient tax refund and customs clearance, backlog of orders, and financial difficulties, the state has successively issued measures to stabilize foreign trade, such as Opinions on Promoting the Stability and Quality of Foreign Trade and a Package of Policies and Measures to Solidly Stabilize the Economy, focusing on stabilizing the industrial chain supply chain and helping foreign trade enterprises to ensure orders, markets and confidence.

  At the same time, relevant arrangements have been made to expand the import of high-quality products, maintain the stability of the international industrial chain supply chain, and study the phased reduction of port-related charges to further support and solve the problems of foreign-funded enterprises’ convenience in doing business in China. Policy measures such as reducing taxes and fees, strengthening financial support, and continuously optimizing the business environment have continued to exert their strength, especially the effect of cross-cycle adjustment and supporting small and medium-sized foreign trade enterprises has continued to emerge, further stimulating the vitality of foreign trade market players. In the first seven months, the number of foreign trade enterprises with import and export performance in China increased by 5.8% year-on-year, among which the import and export of private enterprises increased by 15.3%, accounting for 50% of China’s total foreign trade value, and continued to play the role of "main force" in foreign trade.

  At present, China’s foreign trade development still faces some unstable and uncertain factors, and there are still many pressures to ensure stability and improve quality. On the whole, however, China’s foreign trade was more resilient in the first seven months, which laid a solid foundation for the stability and quality improvement of foreign trade throughout the year. With the continuous increase of macro-policy adjustment, a package of policies and measures has been accelerated to take effect, China’s main economic indicators have improved marginally, and the overall recovery of the national economy has accelerated. A stable and reliable industrial chain and supply chain, a huge market and domestic demand, and a new kinetic energy driven by innovation … … The fundamentals of China’s strong economic resilience, sufficient potential and long-term improvement have not changed, providing a good environmental support for foreign trade development.

  It is conceivable that with the acceleration of a series of national policies and measures to stabilize the economy, the foreign trade logistics is further unblocked, and the enterprises’ resumption of work and production are further accelerated, China’s foreign trade import and export is expected to continue to maintain a steady growth momentum.

The second prize-winning "VacV new generation oncolytic virus products" project can directly kill cancer cells through oncolytic virus, activate patients’ immune response, cut off blood supply in tumors, and bring good news to cancer patients … …

  In addition to the finals, a large number of projects have emerged in each sub-race, which closely combine high-tech life scenes and emerging industries. For example, the two-way temperature-regulating material technology in Tokyo Station in Japan enables people to "dress lightly in spring and wear in winter", high-power smart transistors are applied in new energy innovation systems, and degradable magnesium alloy coronary stents are available.

  In order to take advantage of the competition to connect with international advanced technology and inject "living water" into Shenzhen’s innovation-driven development and industrial transformation and upgrading, the competition settings of this competition are closely related to the latest industrial layout in Shenzhen, and seven major industry competitions are set up, including new generation electronic information, digital and fashion, high-end equipment manufacturing, green and low-carbon, new materials, biomedicine and health, and marine economy. At the same time, in order to solve the technical research and development problems of Shenzhen science and technology enterprises, the "reward competition" system was introduced for the first time, and three prize competitions were set up, namely, technical development of power semiconductor materials, research and development and application technology of new adsorption materials and artificial intelligence detection, to encourage players to "expose the list" and collect high-quality solutions for the world.

  "We attach great importance to talent work and insist on implementing ‘ Strong talent area ’ Strategy, and vigorously create a policy environment and innovative soil to develop talents and talents. " The person in charge of Longgang District Human Resources Bureau said that he hoped to form a brand effect through the competition, select high-quality projects and high-level talents at home and abroad to settle in Longgang and share development opportunities.

  Perfecting post-game service mode and forming innovation chain

  "Many projects in this competition are of very high quality. I look forward to these projects coming to Longgang, Shenzhen. I also hope that team members can combine Chinese and foreign, integrate into the culture of Longgang, Shenzhen, understand the industry situation in Shenzhen and grow better and faster." Cui Shuguang, the judge of this contest and dean of the Future Zhilian Network Research Institute of the Chinese University of Hong Kong (Shenzhen), said.

  The reporter learned that it is not uncommon for award-winning projects to settle in Shenzhen and develop smoothly. For example, Mingcheng Electric Technology (Shenzhen) Co., Ltd., the winner of the 2016 finals, was awarded as "National High-tech Enterprise" and "Guangdong Engineering Technology Research Center" and has completed two rounds of financing with a total amount of nearly 40 million yuan; Shenzhen Hongyida Technology Co., Ltd., which is also a settled enterprise of the winning project in the finals, has applied for more than 30 invention patents and software copyrights. Up to now, of the 350 projects that have come to Shenzhen to participate in the finals, 120 have reached cooperation intentions with Shenzhen, and 47 projects have officially settled in Shenzhen for development. Among them, 26 projects have settled in Longgang, mainly belonging to strategic emerging industries such as high-end equipment manufacturing, new materials and new generation electronic information.

  Dream catchers realize their dreams here, and start-ups grow and develop here, which is inseparable from the "post-game service" model explored in Longgang District. For example, more than 40 venture capital institutions participated in this competition, forming a venture capital pool with a total amount of 25 billion yuan, and investing in outstanding projects in the competition to help the projects realize the transformation of results; The human resources bureau of Longgang District, the executive unit of the competition, actively docked, fully integrated the resources of the government, parks and enterprises, formed a joint force to provide special services, followed up the docking events throughout the process, provided "peer-to-peer" services such as policy recommendation, settlement counseling, park inspection and capital docking, and fully supported the settlement of the participating projects.

  "Next, we will continue to provide life-cycle services for innovation and entrepreneurship projects from the aspects of resource integration, mentor assistance, capital docking, and achievement transformation, so as to create the best innovation and entrepreneurship ecology, and strive to make Longgang District a place where innovation achievements continue to emerge ‘ Origin ’ And the global scientific and technological innovation talents yearn for ‘ Destination ’ Welcome global quality projects and talents to Longgang to create a better future. " The person in charge of the Longgang District Human Resources Bureau said.

  Guangming Daily (December 06, 2021, 09 edition)

Reverse! The prosecutor scrutinized the incident surveillance video frame by frame, and the intentional injury case was changed to self-defense.

CCTV News:Disputes over walking dogs have occurred from time to time in recent years, and some even turned into fierce conflicts and criminal cases. The same is true of this case that we should pay attention to today, because once we walked the dog, the parties went from quarreling to fighting, and finally moved a knife.

Yu Zhou, the procurator of Daxing District People’s Procuratorate, felt that this was an avoidable dispute when consulting the case file of a crime of intentional injury.

Yu Zhou, Procurator of the First Procuratorial Department of Daxing District People’s Procuratorate:As a normal person, it is possible that a little dispute that happened before will end when it is dispersed, and the matter of going home will be over. Under normal circumstances, the incident in the second stage should not happen.

As a party involved, Yan Xiaofeng, a security guard of a pharmaceutical company in Daxing District, Beijing, did not expect that he and the other party were strangers, and only because of an accidental small conflict, it actually triggered a strong chain reaction.

 Yan Xiaofeng:Unexpectedly, no one expected that there would be follow-up events.

Quarrel with the dog owner because the dog broke into the security guard.

So what caused this conflict, and then what chain reaction? It all started with a dog.

At 7: 17 am on August 6, 2018, the electric door of a pharmaceutical company in Daxing District of Beijing slowly opened to welcome colleagues who came to work. The first thing that greeted them was an "uninvited guest".

At 7: 21, Song Shiquan, who was not tied with a dog leash, swaggered into the company yard and got into the bushes on the left side of the gate to "make it convenient". At this time, two people appeared in the door and outside, including Yan Xiaofeng, the company’s security guard.

Yan Xiaofeng:I’ll kick the dog out first, but it won’t go.

Seeing that the dog didn’t move, Yan Xiaofeng made a gesture of waving and hitting. It was this action that angered Yang, who appeared outside the company. He was the owner of the dog and lived in a residential area across the street from the company. Yan Xiaofeng recalled that Yang was often seen walking his dog nearby, but the two never talked. Ten seconds later, two people who didn’t meet each other spoke for the first time, but they were not friendly.

Speech conflict becomes physical conflict, fighting for two minutes.

According to Yang’s inquiry transcript, at that time, because he saw Yan Xiaofeng picking up a stone and hitting his dog, he scolded, and Yu Shisheng came out in the security room and the three men clashed. At this point, the troublemaker Song Shiquan has run to the door from the bushes, but the conflict between the three people has not stopped, and it has escalated from an argument to pushing each other.

Yan Xiaofeng:After Yu Shisheng came out, there was a conflict when they talked. At this time, they scratched, and this man scratched me. At this time, I grabbed him and kicked him out. He was also very strong. The two of us couldn’t push him, so I hit him.

The monitoring screen shows that Yang hit Yan Xiaofeng with a plastic cone, and he himself was knocked down by Yu Shisheng. The whole fighting process lasted only two minutes. At 7: 23, Yang ran across the road.

Yan Xiaofeng:He went to the opposite side of the road. I think what he meant was that he was looking for something. Later, he led the dog back. We thought it was pulled down, and no one suffered anything, so it was over.

Thought things had subsided, but the second round of conflict escalated

In the view of security guard Yan Xiaofeng, both sides are at fault, and they are all "hanged", which is even. However, Yang didn’t think so. According to the police’s inquiry record afterwards, he felt that he had suffered a loss in one pair, so he decided to send the dog home first and then find a way.

Seeing that Yang had left, two security guards continued to stand at the door to greet the employees who came to work. Since Yu Shisheng also called the police before, at 7: 31, Yu Shisheng received a phone call from the police asking about the previous alarm. At this time, Yan Xiaofeng, who was standing outside the door, suddenly found that Yang was coming towards them in an imposing manner, waving a kitchen knife in his hand.

Yan Xiaofeng:Looking back, I don’t know, he took the knife. I said close the door quickly. When Yu Shisheng and I were about to close the door, he had already reached the door and walked very fast. As soon as I saw him here, I hurried into the house.

Seeing that the other side was going to rush in with a knife, Yan Xiaofeng returned his hand and took the riot steel fork.

The two security guards joined forces to counter each other and brandished swords at each other.

 Yan Xiaofeng pushed Yang out of the company with a riot steel fork, and Yu Shisheng also rushed out of the security room with a rubber stick to fight back with Yang. In this process, Yang also tried to cut two security guards with a kitchen knife.

At 7: 33, the arc-shaped head of the explosion-proof steel fork used by Yan Xiaofeng was discounted. He hit Yang’s shoulder and chest with the remaining steel bar, and Yang fought back with a kitchen knife. At this time, several employees have gathered at the door of the company to persuade both parties. According to Yang’s inquiry transcript, he felt that these employees were more polite and had their own steps, so they stopped doing it.

At this time, Yang’s chest and arms have been injured, and Yan Xiaofeng’s arm is also bleeding. The two sides confronted each other inside and outside the door, but did not start work again. Soon, the police rushed to the scene and took the three people to the police station for investigation. During the investigation, Yang complained of arm pain and was taken to the hospital for treatment.

Two security guards were detained for causing minor injuries to each other.

After investigation by the police, it was determined that this was a case of mutual assault, and both parties were responsible. The owner of the dog, Yang, was detained for 10 days in administrative detention, while two security guards were criminally detained on suspicion of intentional injury because Yang was slightly injured. A small conflict, and finally both sides paid a painful price. However, the development of this case has not ended here.

During the investigation of the case, Yan Xiaofeng and Yu Shisheng apologized for the damage caused to the victim Yang and expressed their willingness to make compensation within their ability, but the two sides did not reach an agreement on the amount of compensation.

Yan Xiaofeng:He wants 200 thousand, and I want 200 thousand, so I won’t come to Beijing to work, you know? I have a pension of more than 4,000 yuan, but this 4,500 yuan is just enough for my son to take medicine for one month. What do you say?

Although the two sides disputed the amount of compensation, both Yan Xiaofeng and Yu Shisheng admitted that they had committed criminal acts and had no opinion on the crime of intentional injury.

Yan Xiaofeng:Because I thought at that time, after all, the person was beaten, and the disability appraisal came out. No matter what the matter was, you beat the person, which you have to admit, whether you are right or not, this happened.

The prosecutor overturned the guilty conclusion after reviewing the case file.

 On October 29, 2018, the case was transferred to the People’s Procuratorate of Daxing District, Beijing for review and prosecution. However, after carefully reviewing the case, the prosecutor Yu Zhou came to a different conclusion from the public security organ.

Yu Zhou, Procurator of the First Procuratorial Department of Daxing District People’s Procuratorate:The public security organ believes that the victim Yang was injured as a result of fighting between the two sides. After review, we believe that this case should be divided into two stages: the first stage is that the two sides fought each other, but there was no consequence of causing minor injuries to the victim. If the circumstances are obvious, slight and harmless, it is not considered a crime. The second stage is the victim Yang, who went home to get a kitchen knife and rushed back to the pharmaceutical company.

After investigation, Yang’s minor injury was caused after he returned to the scene again, and the procuratorate believed that the actions of the two security guards this time were self-defense.

Yu Zhou, Procurator of the First Procuratorial Department of Daxing District People’s Procuratorate:In the second stage, although it caused the consequences of Yang’s minor injury. Yang’s behavior is a kind of illegal infringement, and the behavior of the two suspects belongs to legitimate defense.

Self-defense comes from Article 20 of China’s Criminal Law, the first paragraph of which stipulates that: in order to protect the state, public interests, personal, property and other rights of oneself or others from ongoing illegal infringement, the act of stopping illegal infringement, which causes damage to the illegal infringer, belongs to self-defense and does not bear criminal responsibility.

 Zhang Renjie, Director of the First Procuratorial Department of Daxing District People’s Procuratorate:The criminal suspect in this case actually has the intention of breaking in with a knife. At this time, the suspect can take a protective steel fork, which is not a murder weapon. In this case, in order to stop his injury, he was injured. Therefore, we believe that this case is ultimately a legitimate defense.

Whether it is justifiable defense is controversial and controversial.

If Yan Xiaofeng and Yu Shisheng caused Yang’s minor injuries in self-defense, it means that they do not constitute a crime, will not be prosecuted according to law, and will not be liable for compensation. However, after all, this case was caused by a fight between the two sides. Is this fight in the back considered as self-defense? There are also disputes within the procuratorial organs.

Zhang Renjie, Director of the First Procuratorial Department of Daxing District People’s Procuratorate:There are great differences and disputes within the procuratorial organs.

Due to disagreement within the procuratorial organs, on December 13, 2018, the People’s Procuratorate of Daxing District of Beijing convened the procuratorial committee for the first time to discuss this case.

Not only this case, but also "self-defense" caused a heated discussion throughout the country at that time. This case in Daxing District of Beijing took place on August 6, 2018. More than half a month later, the "Kunshan Anti-homicide Case" occurred. This case was described by the media as awakening the sleeping self-defense clause, and then the case of Zhao Yu, Fujian Province, and the case of Laiyuan’s home invasion and anti-homicide occurred one after another. People also discussed the standard and scale of self-defense identification and the problems existing in judicial practice for a long time. This case happened in Daxing District, Beijing, although it didn’t attract much attention at that time, all kinds of disputes about the determination of self-defense were fully reflected in this case.

 Due to the lack of consensus, the first inspection Committee did not form a final resolution. The inspection commission asked the undertaker to conduct supplementary investigation on this case. During this period, on December 14, 2018, Yu Shisheng and Yan Xiaofeng were released on bail by the People’s Procuratorate of Daxing District, Beijing. Compared with four months ago, Yan Xiaofeng’s understanding of the case has also changed.

Five days after Yan Xiaofeng was released on bail pending trial, on December 19, 2018, he saw a number of guiding cases of self-defense and excessive defense issued by the Supreme People’s Procuratorate. These cases specifically explain the boundaries and grasp standards of justifiable defense, further clarify the protection of the right of justifiable defense, actively solve the outstanding problems in the application of justifiable defense, and provide judicial reference for procuratorial organs.

Yan Xiaofeng:The Supreme People’s Procuratorate has published four examples of self-defense, one of which is similar to mine. Because you came in with a knife and you have come to my yard, I will push you out, but I won’t hit you right away. After all, you threatened me with a kitchen knife.

Hold the second inspection Committee to review the video of the crime repeatedly.

Comparing four guiding cases, Yan Xiaofeng thinks that his behavior is defensive, and for the victim Yang, after all, it caused minor injuries in this conflict. How should the behavior of the two suspects be determined? All this requires careful analysis and judgment by prosecutors.

After the case was returned to supplementary investigation twice, the second inspection Committee was held on April 4, 2019.

Zhang Renjie, Director of the First Procuratorial Department of Daxing District People’s Procuratorate:At that time, the undertaker put down the most critical paragraphs at a very slow speed every frame and second of the case, so that every member of the inspection Committee could see the situation very clearly.

After further discussion, the procuratorial Committee reached a consensus that the case was divided into two stages, but the legal evaluation of the second conflict still showed three viewpoints: intentional injury, excessive defense and legitimate defense. Among them, the view that it constitutes the crime of intentional injury is that two parties can hide in the guard room at the time of the crime, that is to say, they can avoid the second conflict by avoiding it.

Yu Zhou, Procurator of the First Procuratorial Department of Daxing District People’s Procuratorate:We believe that self-defense cannot require the defender to passively evade and not allow him to fight back. First of all, in this case, we can see the door of the security room through monitoring, and we also saw it when we went to the scene. Half of the door is glass, and the bottom is aluminum alloy, which is not a solid security door. Once Yang rushed into the guard room with a kitchen knife, in a particularly small space, there was no way for the two suspects to maneuver, which would be even more dangerous.

After the incident, this question has been hovering in Yan Xiaofeng’s mind: What would have happened if he had been hiding in the guard room?

Yan Xiaofeng:I thought about it at that time, too. What would happen if I didn’t go out at that time? But employees are going to work. What should we do at this time? What should I do to cause this impact? Because the purpose of my coming here is to ensure the safety of employees and the safety of the factory, I have to do this.

Prosecutor: The security guard has the right to stop the act of breaking into the company with a knife.

Through monitoring, it can be clearly seen that the two security guards have struck Yang, so can these actions indicate that they have the intention of intentional injury? Regarding this controversial point of view, Yu Zhou believes that the two parties are security guards of pharmaceutical companies, who not only have the right to protect themselves from infringement, but also have the duty to protect the personal safety of other employees. At the time of the crime, it was the time for employees to go to work one after another on Monday morning, and someone broke into the company with a knife. As a security guard, it must be stopped.

In the discussion of the procuratorate, there was another view that Yang was just bluffing and didn’t really hack people, and the two suspects were not actually injured. If they were injured, they could be considered as self-defense.

According to Yang’s inquiry transcript: "After the first fight, I think the other party thinks that they have the upper hand and are very proud, so I want to scare the other party and let the other party not think that I am good at bullying."

The transcript also wrote: if the other party still pretends to be with me, then I may actually cut the other party twice. But when I arrived, the other party took out a steel fork and rubber roller, and I felt that the other party was a little scared, so I waved the knife twice without really cutting them.

Regarding the problem that the victim didn’t really want to chop someone up and the two suspects weren’t injured, prosecutors such as Yu Zhou thought that at the time of the incident, the two suspects were facing realistic and urgent danger, and it was too harsh to ask them to fight back after being injured.

If the actions of the two suspects belong to self-defense, is their actions excessive? According to the second paragraph of Article 20 of the Criminal Law, excessive defense means "justifiable defense obviously exceeds the necessary limit and causes great damage". Prosecutor Yu Zhou believes that this case does not constitute "excessive defense" either from the result of Yang’s minor injury or the means of the two suspects.

Yu Zhou, Procurator of the First Procuratorial Department of Daxing District People’s Procuratorate:The result did not cause significant damage, but the result was not excessive. In this case, we saw the two security guards holding proprietary security tools distributed by the security company. Among them, Yan used a U-shaped explosion-proof steel fork to push Yang’s upper body outside the company. When Yang swung at Yu with a kitchen knife, Yu took a rubber baton and hit Yang’s left hand. We think that in this case, the means of defense of the two suspects are not excessive.

Moreover, the prosecutor in Yu Zhou believes that in judging whether it is justifiable defense or excessive defense, we should not only emphasize the equivalence of actual damage results of both sides, but also compare the interests of both sides. When the personal safety and life safety of defenders are in imminent danger, they should be allowed to defend.

Intentional injury, justifiable defense, and excessive defense are very different from each other in terms of results, but they may only be separated by the same distance as hair, which needs to be judged carefully by law enforcers. Then, after two discussions by the procuratorate, what conclusion did the prosecutors finally reach?

The procuratorial Committee finally decided not to prosecute.

Through the judgment of the case and the detailed analysis of the legal application of self-defense, the procuratorial Committee finally reached an agreement that the actions of the suspects Yu Shisheng and Yan Xiaofeng belonged to self-defense and were not enough to constitute a crime according to law. On April 8, 2019, the People’s Procuratorate of Daxing District of Beijing made a decision not to prosecute Yan Xiaofeng and Yu Shisheng.

On April 10, 2019, Yan Xiaofeng and Yu Shisheng, accompanied by lawyers, came to the Daxing District People’s Procuratorate in Beijing, and a hanging heart finally landed.

Yan Xiaofeng:I just don’t think I’m sure I’ll go back, but when I was struggling, the prosecutor announced that I wouldn’t sue. I was in tears. Really, my mood was different and I was released immediately.

For Yan Xiaofeng and Yu Shisheng, this non-prosecution decision recognized from the legal level that the two men "took actions to stop illegal infringement in order to protect themselves and others’ personal rights from ongoing illegal infringement". In the eyes of their defense lawyers, through this non-indictment, what they see is the rigor and meticulousness of the prosecutors and the time and energy invested. In particular, dividing the case into two stages makes the legal judgment clearer.

After getting the indictment, Yan Xiaofeng still returned to the pharmaceutical company as a security guard. After experiencing this storm, Yan Xiaofeng, who usually likes to watch legal programs, has a more personal experience of the "fairness and justice" that is often said on TV.

Yan Xiaofeng:It’s true to handle cases fairly, and it’s fair in my life, because many things can be felt before this, and judicial justice is reflected in this prosecutor.

At present, the party Yang has filed a criminal private prosecution with the court. In this case, the inspection Committee was held twice, and the views collided fiercely, and the argument was rigorous and meticulous, only to finally draw a conclusion that can stand the test of all parties. Fairness and justice have also emerged in this process.

Promoting the high-quality development of state-owned enterprises with digital thinking

    General Secretary of the Supreme Leader pointed out that developing the digital economy is a strategic choice to grasp the new opportunities of the new round of scientific and technological revolution and industrial transformation. The healthy development of the digital economy is conducive to promoting the construction of a new development pattern, a modern economic system and a new competitive advantage of the country. As the backbone of national economic development, state-owned enterprises should contribute to the development of digital economy.

    Strengthen the leadership of party building in state-owned enterprises.State-owned enterprises not only have the inherent appeal of creating economic profits, but also need to undertake the heavy responsibility of consolidating the party’s ruling foundation, so as to achieve the organic unity of improving the economic and social benefits of enterprises and preventing and controlling risks. The establishment of digital thinking in state-owned enterprises is not only the need of enterprise economic development, but also the practical need of maintaining public ownership. However, due to its wide coverage, slow effectiveness and large capital investment, it is difficult for enterprises to do this only by relying on a certain department, and it is necessary for party organizations to play their role of commanding the overall situation and coordinating all parties. Party organizations in state-owned enterprises play an important role in the digital construction of enterprises. In order to truly realize the empowerment and cohesion of party organizations for the high-quality development of state-owned enterprises, the party organizations of state-owned enterprises need to make four changes: First, the transformation from management to service. Adhering to the Party’s overall leadership, Party organization construction should strive to meet the reasonable demands of all stakeholders as much as possible, and close the relationship between the Party and the masses through diversified services. The second is the change from bureaucratic type to network type. General Secretary of the Supreme Leader pointed out that "there is no national security without cyber security, and there is no modernization without informationization". The digital construction of enterprises can not be separated from massive information and complete network system, which will also promote the development of enterprise organizational structure from the original vertical hierarchical system to the flat simulation market network.State-owned enterprises should adapt to the networked enterprise organizational structure and actively explore the establishment of a new model of party-mass work with the new concept of networked management. The third is the transformation from closed type to open type. With the deepening of digital construction, various new ideas are constantly emerging, and the speed of knowledge updating is accelerating. This requires the party and mass workers in enterprises to establish an open concept, keep abreast of the latest trends of workers’ thoughts and the development and changes of the international situation, strengthen ideological and political guidance, and enhance the pertinence and effectiveness of party and mass work. The fourth is the transformation from extensive to fine. In the process of party organization construction in state-owned enterprises, party and mass workers should examine and reflect on the management mode in time, firmly grasp the "people", "concepts" and "digital technology", work hard on the combination, make a fuss, grasp the implementation, work hard on the application of lean tools and methods, and seek improvement and practical results.

    Cultivate independent innovation talents in digital technology.Nowadays, China’s digital economy is developing with each passing day, but there is a big gap in talents related to digital technology. Faced with this challenge, state-owned enterprises must unify their understanding and actions through excellent corporate culture, stimulate the enthusiasm and creativity of independent innovation talents in digital technology within enterprises, and then enhance the innovation ability and core competitiveness of state-owned enterprises. By constructing a good talent training mechanism, use mechanism, incentive mechanism and competition mechanism, we can not only cultivate high-quality professional cadres, but also cultivate innovative digital technology talents, and provide talent support for the high-quality development of state-owned enterprises. In view of the shortage of digital technology talents, state-owned enterprises can solve it through three ways: First, seek professional support from the state. We will provide intellectual support for high-quality development by inviting the state to set up a digital technology expert group to visit enterprises on the spot and provide remote guidance by digital technology experts. The second is cooperation with universities. Through the establishment of enterprise base classes and other forms, the "order-based" talent training is implemented to meet the needs of digital talents in enterprises. The third is to strengthen the training of existing digital talents in enterprises to meet the needs of digital development in the new stage. By promoting internal and external knowledge transfer, strengthening the construction of information team, and forming "key users — Internal consultant — The three-level operation system of external consultant.

    Strengthen the digital infrastructure construction of state-owned enterprises.From "asset-driven" to "data-driven", it is necessary to improve the digital infrastructure, organically couple with traditional resources, and realize the interconnection of data production, storage, sharing and analysis within the enterprise resource architecture. To establish digITal thinking, it is necessary to build brand-new IT structural models such as "data center" and "business center" that meet the operating characteristics and development needs of state-owned enterprises, and establish a digital information technology empowerment platform for state-owned enterprises with the protection of agile and efficient new digital information technology infrastructure to stimulate new kinetic energy of data elements and make data become productive forces. To this end, state-owned enterprises need to do the following three things in building digital infrastructure: First, raise awareness of the importance of digital infrastructure construction. For state-owned enterprises, accelerating the construction of digital infrastructure can, on the one hand, promote technological transformation and equipment renewal, and provide strong support for the conversion of old and new kinetic energy; On the other hand, it can promote the rapid iteration of application scenarios and business models such as intelligent transportation, smart city, intelligent manufacturing and smart energy, and form new economic growth points for the new round of investment expansion. The second is to clarify the main tasks of digital infrastructure construction. Digital infrastructure construction covers not only sensor terminals, 5G networks, big data centers, industrial Internet, etc., but also the use of next-generation information technologies such as Internet of Things, edge computing and artificial intelligence.Digital, networked and intelligent upgrading of traditional infrastructure such as transportation, energy, ecology and industry. The third is to increase the human, financial and material support for the construction of digital infrastructure. Digital infrastructure construction is a systematic project, which requires state-owned enterprises to strengthen the investment of people, money and materials through various measures, and also to jointly develop technology and build facilities by introducing third-party channels.

    Improve the governance system of state-owned enterprises.The penetration of digitalization into all levels of state-owned enterprises forces enterprises to transform, and the requirements for the reconstruction of internal production, operation and management mechanisms are becoming more and more urgent. The State-owned Assets Supervision and Administration Commission (SASAC) also mentioned in the Notice on Accelerating the Digital Transformation of State-owned Enterprises that digital transformation is not only a top-ranking project, but also an innovative activity involving all employees and all elements. It is necessary to fully stimulate the vitality of grassroots innovation, create an atmosphere of being brave, willing and good at digital transformation, and strengthen the next game of chess. It can be said that the establishment of digital thinking requires the transformation of all employees of the enterprise, involving cross-organizational and cross-departmental collaborative work, so it should be considered comprehensively. Specifically, state-owned enterprises need to build a "four-in-one" governance system: first, promote the reform of corporate shareholding system. According to the development goal of digital construction, state-owned enterprises should clarify their development ideas, build a scientific management system, and effectively provide protection for the deserved interests of digital technology talents. The second is to improve the corporate governance structure. State-owned enterprises should standardize the construction of the board of directors, effectively implement the functions and powers of the board of directors, reform the management system of external directors, and strictly manage the selection and appointment of directors, so that the board of directors can truly become the decision-making body of enterprises, thus giving voice to digital technology talents and enhancing their voice and influence. The third is to manage the digital technology leaders of state-owned enterprises by classification and stratification. According to different categories and levels of state-owned enterprises, there are many flexible ways to promote and appoint digital technology leaders in state-owned enterprises, such as appointment system, selection system and appointment system, but they must pass strict examination.The fourth is to improve the salary distribution system of state-owned enterprises. Whether the state-owned enterprises can establish a salary distribution system that conforms to the economic law and the law of digital technology personnel training is related to the vital interests and potential of enterprise employees, the implementation of the salary incentive function and the strategy of "strengthening enterprises with talents", and the long-term development of enterprises and the stability of people’s hearts. To this end, state-owned enterprises must establish and improve the salary system with the purpose of encouraging labor and enhancing the creative vitality of digital technology talents, reflecting efficiency and promoting fairness.

Open the door remotely, change your face and sound? How to ensure security in the AI era?

  CCTV News:Network security is related to many aspects of production and life. In recent years, artificial intelligence technology has brought many conveniences to people, but also brought many new challenges to network security.

  A loophole may become a hacker’s "key"

  Nowadays, unmanned driving is no longer a scene in science fiction, but has become a reality in many places in China. However, what will happen if a smart car is attacked by a network? Network security experts simulated this scene for us.

  Network security expert Deng Qinyang:Hackers invade our vehicles through the network, and then move horizontally to take advantage of related loopholes in parts. Now the user is driving the vehicle normally, and then I can simulate a hacker’s remote attack on our door (system) to realize an operation of opening the door remotely. Now our system detects an instruction to open the door remotely during driving, so it is very dangerous for our door to be opened during real driving.

  According to experts, if the security vulnerability is only aimed at the application level, the threat is limited to individuals. However, if hackers attack the underlying systems such as driving and communication, the damage will be more extensive.

  Build a "safety base" and fasten the network "safety belt"

  The data shows that in 2023, there were 8.05 million attacks on domestic car networking service platforms, a year-on-year increase of 25.5%. It is urgent to build the "safety base" of intelligent networked cars. In this regard, China has issued a number of relevant laws and regulations, and issued and implemented a number of vehicle safety standards and more than ten platform safety standards.

  How to ensure safety and distinguish authenticity in AI era

  In addition to the unmanned field, many lawless elements also use AI to change their faces and voices, infringing on citizens’ personal privacy. A "portrait photo" and a close-up video of people may become new tools for criminals.

  "Face-changing" forged indecent photos, extortion by criminals

  Not long ago, Mr. Wu of Shenzhen suddenly received a multimedia message from a strange mobile phone number. When he clicked on it, it turned out to be an indecent photo of him and a strange woman in the hotel room.

  Party Mr Wu:He threatened to contact me before what time to transfer money to him. As soon as I thought something was wrong, I called the police.

  After receiving the report, the police immediately conducted an investigation. By combing the report records, the police found that Mr. Wu was not the only one who had the same experience. With the deepening of the investigation, the police found that this was a criminal gang with a clear division of labor. Some people are responsible for retouching, some are responsible for finding targets, and some are responsible for extortion. Subsequently, the police launched a unified network-receiving operation and successfully arrested more than 10 suspects headed by Wang.

  Wei Zhang, a policeman from Pingshan Branch of shenzhen public City, Guangdong Province:Relevant evidence extracted from the suspect’s computer, these pictures are the victim’s picture information collected by the suspect from various channels such as the Internet, and then they are synthesized, which is the indecent photos synthesized by the suspect and used to blackmail the victim. 

  It only takes one photo to confuse the fake with the real.

  So how do these fake photos get the real thing? Network security experts demonstrated the technology of "AI face changing" for us, which only needs a static photo of the target character to make the characters in the photo move.

  Jaco, member of the Professional Committee of Artificial Intelligence Security Governance of China Cyberspace Security Association:The rightmost side of itself is a static picture that won’t move, so after our (presenter) does some actions, it (AI face-changing software) collects the moving features of (presenter) face, and integrates this feature into a static picture, so that the picture moves according to our (presenter’s) actions. At present, AI face-changing technology is still relatively mature, and it can also support real-time face-changing of video calls. If it is combined with changing the background environment, changing the sound, etc., the fidelity will be higher and it will be more difficult to distinguish. 

  Accelerate the development and application of related countermeasures technology.

  In view of the abuse of technologies such as "AI face-changing", a few days ago, the National Network Security Standardization Technical Committee released the 1.0 version of the "Artificial Intelligence Security Governance Framework", proposing corresponding technical responses and comprehensive prevention measures, as well as guidelines for the safe development and application of artificial intelligence. In this regard, network security experts suggest that we should speed up the development and application of related countermeasures and use AI to govern AI.

  How to ensure safety and personal privacy in the AI era

  To guard against the threat posed by AI, what should we ordinary people pay attention to in our daily life besides upgrading our efforts in technology?

  Avoid excessive disclosure of information such as face fingerprints.

  According to experts, the most critical reason for AI’s face-changing and other illegal acts is the disclosure of personal privacy information. Therefore, we should try to avoid excessive disclosure and sharing of personal biological information such as faces and fingerprints in the daily online process. If you receive a video that looks like "family" and "leader" and other transfers and remittances, you must carefully identify them.

  Be alert! Don’t send these three kinds of photos casually

  In addition, experts suggest that the following photos should not be posted on the Internet.

  First, don’t publish hand-held ID cards or hand-held white photos, which will contain sensitive information such as personal name, ID number and address.

  Second, don’t post photos of all kinds of bills. Many people like to take train tickets or plane boarding passes when traveling on business and travel, and send them to their circle of friends to share. These bills will not only contain information such as name, place of departure, destination, etc., but also the personal information of passengers in the stripe code or QR code, which may be cracked and stolen by criminals. 

  Third, don’t take photos such as home keys and license plates. Through big data and other technical means, criminals will analyze the specific location of the publisher at a specific time through these photos, and will also obtain the relevant living habits of the publisher.
