Premiere

On August 2, the police action movie "Apostle Walker 2: Operation Spy Shadow" held a media conference and premiere in Shanghai. Director Wen Weihong, starring Zhang Jiahui and Jiang Peiyao, attended the exchange. Zhang Jiahui revealed at the scene that his brotherhood with Koo Tianle in this episode will have different sparks, and the conflict will be more intense, and the identity will be more mysterious.

The film begins with an accidental separation of childhood friends. Thirty years later, due to a crime, the former brothers meet again, but they are already in different camps. As the investigation of the crime deepens, a terrorist organization that has been hidden behind the scenes for many years gradually emerges. The slogan of the film, Reunion, seems to imply that no matter where we are in different camps, what cannot be parted is always brotherhood.

Wen Weihong, Zhang Jiahui and Jiang Peiyao were present to communicate

The film is the return of the "Apostle Walker", a gold-medal IP film version, three years later. At the event, when it comes to the cooperation with Koo Tianle again, Zhang Jiahui bluntly said that there is no shortage of sparks, "Because the selling point of this film is the action scenes, and the brotherhood between Koo Tianle and me. The director also understands the needs of the audience, so the action scenes and brotherhood scenes are emphasized a lot, and this time there are many contradictions and the identity is particularly mysterious. Maybe many people will think that the second episode of the movie is generally not as good as the first, but I think the second episode of" Apostle "is definitely better and more exciting."

Zhang Jiahui and Jiang Peiyao took a group photo at the scene

It is worth mentioning that the film retains the three classic elements of the previous work: cops and bandits, undercover, brotherhood, and the gold medal lineup of directors and starring stars, but it starts the story with a new character relationship. The battlefield of brothers has also changed from Brazil in the previous work to Myanmar and Spain this time. Zhang Jiahui, Koo Tianle, and Wu Zhenyu’s "Iron Triangle" will perform a new spy operation with a new identity.

Zhang Jiahui was interviewed by the media

When asked about the role of this time, Zhang Jiahui revealed, "In the first episode, Gu Tianle and I had conflicts and developed the plot at the level of the police, but this time we are not only at the level of the police, but also promoted to the level of agents. The title of the film also mentions’Operation Spy. ‘The director said that when he was filming a TV series, there were a few faces that he wanted to develop, but these ideas could not be presented in the TV series, so after the first episode of the movie version was approved, he could realize the story he wanted to unfold before and bring it out in this episode one by one. I think the director’s intention this time is to give everything he has." And director Wen Weihong said that the purpose of this shooting is to give the audience the most authentic feeling, without relying too much on computer special effects, and the actual shooting.

　　In October, 2020, the Fifth Plenary Session of the 19th CPC Central Committee took "accelerating the construction of a new development pattern with the domestic macro-cycle as the main body and the domestic and international dual-cycle promoting each other" as one of the guiding principles and main goals of China’s economic and social development during the 14th Five-Year Plan period. The socialist basic economic system is a great creation of the party and the people. At present, to accelerate the construction of a new development pattern, we must adhere to and improve the basic socialist economic system, and further transform institutional advantages into governance efficiency to promote high-quality economic development.

　　First, the socialist basic economic system is an important institutional basis for building a new development pattern.. General Secretary of the Supreme Leader pointed out that "to build a new development pattern, we have significant institutional advantages and a solid foundation for reform". This remarkable institutional advantage mainly comes from the socialist basic economic system such as public ownership as the main body, the common development of various ownership economies, distribution according to work as the main body, the coexistence of various distribution methods, and the socialist market economic system.

　　First, adhering to public ownership as the main body and the common development of diversified ownership economies means fully mobilizing social resources in the form of ownership that adapts to the development level of productive forces, encouraging cooperation and competition among diversified ownership economies, promoting the public ownership economy to deepen reform, adjust and optimize its layout, improve its realization forms, and continuously enhance its competitiveness, innovation, control, influence and ability to resist risks. Secondly, distribution according to work is the main body and various modes of distribution coexist, which is based on protecting the income of workers and encouraging them to get rich through hard work, and fully stimulates the market vitality of production factors such as labor, capital, technology and management through a reasonable mechanism in which contributions are evaluated by the market and rewards are determined according to contributions. Third, the socialist market economic system not only emphasizes the decisive role of the market in resource allocation, but also enables various resource elements to be efficiently allocated through the unique selection mechanism and incentive function of the market; It also emphasizes giving full play to the role of the government and effectively preventing market failure and polarization, highlighting the overall pattern of dual regulation between the market and the government. These three aspects of the socialist basic economic system complement each other and are unified in the great practice of Socialism with Chinese characteristics’s economy.

　　The socialist basic economic system is not only conducive to stimulating the vitality of various market players, liberating and developing social productive forces, but also conducive to promoting the organic unity of efficiency and fairness, and constantly achieving common prosperity, showing the remarkable advantages of the Socialism with Chinese characteristics system. To speed up the construction of a new development pattern, it is inherently required to adhere to and improve the basic socialist economic system and stimulate new vitality of economic development with institutional advantages.

　　Second, the historic achievements of reform and development highlight the remarkable advantages of the socialist basic economic system.. Since the founding of New China, China has developed from "poor and white" to the second largest economy in the world, creating a miracle of rapid economic development that is rare in the world. Behind this miracle, it is a strong guarantee for the continuous consolidation and improvement of the socialist basic economic system, and it is a constant manifestation of the advantages of the socialist basic economic system.

　　In the early days of the founding of New China, China established an independent and relatively complete industrial system and national economic system, which fundamentally solved the problem of "starting from scratch" in industrialization. However, due to the relatively closed development mode of domestic circulation, China’s economic development is generally lagging behind. Since the reform and opening up, China has realized the transformation from a planned economy system to a socialist market economy system. With the gradual establishment of a foreign-related economic and trade management system and the deepening of reform and opening up, China has established a mutually beneficial and cooperative linkage development relationship with the world, and its economic development has achieved sustained and rapid growth characterized by its active participation in the international cycle. Since the outbreak of the global financial crisis in 2008, the kinetic energy of the international grand cycle has obviously weakened, and China’s economy has continued to transform into a growth model dominated by domestic consumption demand, and the vitality of the domestic grand cycle has become increasingly strong. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee has comprehensively deepened the reform of the economic system, adhered to the structural reform of the supply side internally, accelerated the transformation of the mode and adjusted the structure, and accelerated the formation of the situation with the domestic big cycle as the main body; We will build an economic corridor across the East, West and North, and strive to cultivate new advantages in international cooperation and competition. The situation of mutual promotion of domestic and international double circulation has made steady progress, laying a solid foundation for promoting China’s high-quality economic development.

　　In the historical process of reform and development, the basic role of the socialist basic economic system has been constantly highlighted, especially in the process of integrating into the international economic cycle. While accelerating its own development, China has actively participated in global economic governance and promoted economic globalization in a more open, inclusive, inclusive, balanced and win-win direction, which has made important contributions to world economic development.

　　Third, adhere to and improve the basic socialist economic system in building a new development pattern.. Since 2020, the COVID-19 epidemic has spread all over the world, and the global industrial chain and supply chain have been greatly impacted. The tide of "anti-globalization" has surged, and the economic situation is complicated and severe. China’s "14th Five-Year Plan" timely puts forward major strategic arrangements to accelerate the formation of a new development pattern, which points out the direction for achieving higher quality, more efficient, fairer, more sustainable and safer development and stimulating world economic recovery and growth.

　　With the change of factor endowments in China’s external environment and economic development, the growth of domestic demand and the deep development of domestic market have become the main driving forces for China’s sustained economic growth. To build a new development pattern, we must persist in improving the basic socialist economic system, organically combine the implementation of the strategy of expanding domestic demand with deepening the structural reform of the supply side, and form a higher level dynamic balance in which demand pulls supply and supply creates demand; Adhere to the "two unswerving", speed up the layout optimization and structural adjustment of the state-owned economy, promote the healthy development of the non-public economy, and realize the complementarity, mutual promotion and common development of various ownership systems; Persist in further improving the income distribution system, attach importance to the leading role of the market in the initial distribution and the regulatory role of the government in redistribution, and coordinate the income between urban and rural areas, regions and social groups by means of national budget, transfer payment, social insurance and welfare, and continuously promote shared development; Adhere to the domestic macro-cycle, build a new open economic system at a higher level, give full play to comparative advantages, attract global resource elements with the domestic macro-cycle, make full use of domestic and international resources, and promote the coordinated development of domestic demand and external demand, import and export, and introduce foreign capital and foreign investment.

　　To build a new development pattern, only by adhering to and perfecting the socialist basic economic system, being good at using institutional advantages to cope with the impact of risk challenges and transforming institutional advantages into governance efficiency can we foster opportunities in the crisis, create new opportunities in the changing situation, and promote China’s economic stability and far-reaching.

1905 movie network news Directed by Qiu Litao, supervised by Andy Lau, starring Louis Koo, Michael Miu and Lin Jiaxin, starring Zhang Guoqiang, Chen Jiale, Wei Shiya, Gong Shuoliang, Ouyang Jing and Li Shang, and starring Zheng Zeshi, Lin Jiadong and Ying Caier, will be released nationwide on July 5.

On July 4th, the film released a special feature of Louis Koo. In the special edition, Louis Koo’s fierce and arrogant eyes reveal the role of this drug Lord. On the set, Louis Koo had a serious discussion with the director and the staff. In the film, he completely understood the villain with a vicious surface and complicated inner world. Andy Lau, Michael Miu, Lin Jiaxin and other leading actors also expressed their appreciation for Louis Koo’s acting skills.

In the past 20 years, the same door turned against each other because of poison, and Louis Koo’s role detonated the confrontation between the two men

The drug market has been divided into four parts for a long time. Di Cang (Louis Koo) tries to annex the whole Hong Kong drug market with a series of black-and-white incidents, and the anti-drug policeman Lin Zhengfeng (Michael Miu) is trying his best to hunt down drug dealers. On the other hand, Yu Shuntian (Andy Lau), a philanthropist and financial tycoon who is jealous of drugs because he witnessed his father being destroyed by drugs as a child, is offering a reward of HK$ 100 million to catch the biggest drug dealer in Hong Kong, which has caused an uproar in the society and drug gangs have begun to fight among themselves. The storm of offering a reward is actually an undercurrent contest between Dizang and Yu Shuntian. Two decades of brothers are now tit-for-tat sworn enemies, and a life-and-death game between them is poised under this huge "white storm".

Di Cang and Yu Shuntian’s two brothers of 20 years broke up because of drugs. One became a financial tycoon and anti-drug ambassador, while the other became the biggest drug Lord in Hong Kong. From this, the two men launched a showdown between heaven and earth. This special series further shows us the experience of Dizang becoming the biggest drug Lord in Hong Kong from a small gangster and his complicated inner world. With the blessing of Louis Koo’s superb acting skills, a full villain image is presented on the big screen, which is thought-provoking.

The mad drug Lord cited "public anger", and Louis Koo subverted the image and interpreted the villain and was praised by all the staff

In the special edition, the arrogant attitude of the Tibetan people fully shows his ambition to establish his own drug kingdom. "Treacherous, dirty, harmful and absolute bad guys" — — Michael Miu, Lin Jiaxin and others have made such comments on Louis Koo’s Dizang, and all of them can see Louis Koo’s successful interpretation of this villain. In the special edition, Andy Lau said: "His performance has added a lot of color to our whole film." Lin Jiaxin also talked about his feelings and Louis Koo’s feelings about the play: "I feel a little oppressive when he glances at me." Zheng Zeshi praised: "Louis Koo has made great efforts, and his performance is in place." Gaining so many favorable comments also makes people lament Louis Koo’s seriousness and enthusiasm for movies.

As the biggest drug Lord in Hong Kong, Louis Koo plays Di Cang, which is not only ruthless and cruel, but also shows arrogance and arrogance. Even his right-hand man does not hesitate to kill him in the face of his betrayal. At the same time, Louis Koo also expressed his understanding of the role: "Tibet is relatively unethical, and there is no reason to do something." Jun Kung also affirmed in the special edition: "He rarely plays the bad guys." Louis Koo, who rarely plays villains, has created many impressive characters, and his subversive interpretation of this complex character vividly makes everyone look forward to the role and the film.

Soda soda, as an important raw material in chemical industry, its price fluctuation has a great influence on related industrial chains. However, in recent years, the price of soda ash has been continuously depressed and failed to rise effectively. There are multiple factors at work behind this. This paper will discuss these factors in depth and provide strategies to deal with price fluctuations.

Imbalance between supply and demandIt is the primary factor affecting the price of soda ash. In recent years, the global soda production capacity continues to expand, especially in China, where the newly built and expanded soda production lines are increasing. At the same time, the demand growth is relatively slow, especially in the main consumption areas such as construction and glass manufacturing, which fails to keep up with the pace of capacity expansion. This imbalance between supply and demand leads to oversupply in the market, and it is naturally difficult to raise prices.

Raw material costIt is also an important factor affecting the price of soda ash. The main raw materials of soda ash include limestone, salt and ammonia. The price fluctuation of these raw materials directly affects the production cost of soda ash. For example, the rising price of limestone will increase the production cost of soda ash, but due to the fierce market competition, it is often difficult for manufacturers to completely pass on the rising cost to consumers, thus inhibiting the rising price of soda ash.

Policy factorsAlso can’t be ignored. The improvement of environmental protection requirements of governments in various countries has led to the increase of environmental protection costs of soda ash production enterprises. In addition, the government’s regulatory policies on the chemical industry, such as capacity limitation and export tax rebate adjustment, will also have an impact on the price of soda ash. For example, some countries impose restrictions on the export of soda ash, which leads to a decrease in the supply in the international market and a possible increase in the price, but this increase is often short-lived and unsustainable.

Facing the fluctuation of soda ash price, enterprises can adopt various strategies to deal with it. First of all,Optimize the production processIt is an effective way to reduce costs. Through technological innovation and process improvement, enterprises can improve production efficiency and reduce the production cost of unit products, thus gaining an advantage in market competition.

Secondly,Diversified procurement channelsIt is also an important strategy to deal with price fluctuations. Enterprises can establish cooperative relations with multiple suppliers, disperse procurement risks and avoid cost pressure caused by price fluctuation of a single supplier.

Besides,forward marketIt provides an effective risk management tool for enterprises. By participating in soda ash futures trading, enterprises can lock in future procurement costs and avoid the risks brought by price fluctuations. The following are some common futures trading strategies:

Finally,Strengthen market analysis and forecastIt is also an important means to deal with price fluctuations. Enterprises should pay close attention to domestic and international market trends, analyze factors such as supply and demand changes and policy adjustments, and make preparations in advance. By establishing a perfect market analysis system, enterprises can predict the price trend more accurately and formulate reasonable purchasing and sales strategies.

In a word, the price fluctuation of soda ash is influenced by many factors. Enterprises should comprehensively consider the relationship between supply and demand, raw material cost and policy factors, and take effective countermeasures to reduce the risks caused by price fluctuation and ensure the stable operation of enterprises.

CCTV News:The ways and means of extremist organizations to attract recruiters are very tempting and deceptive, and many people are tempted to join the group.

Extreme organization network mapping

According to figures reported by American media, during the period of rapid expansion of extremist organizations, more than 20,000 foreign extremists from more than 90 countries went to Syria and Iraq. This figure is attributed to a systematic and efficient publicity network. With the progress of cracking down on extremist organizations, these foreign extremists either continue to wander around Syria and Iraq or return to their countries of origin. In addition to people like onur who are aware of the true colors of extremist organizations, there are also some stubborn extremists, and their scattered return is still an extremely unstable factor facing all countries in the world.

Massive social media accounts spread brainwashing content

Massive social media accounts spread brainwashing content

According to members of extremist organizations, the usual means of recruiting personnel by extremist organizations is to apply for a large number of accounts on various social media platforms, or develop special media platforms, release bloody videos, instill extreme ideas, or promise false honors. In addition to brainwashing content, extremists will also post life photos such as food and selfies in their personal accounts, trying to convey the illusion of a better life to the outside world to confuse more young people. In view of the great influence of extremist organizations through online propaganda, in recent years, many well-known social media companies have decided to remove terrorist content and close accounts related to extremist organizations.

Private contact fosters intimacy.

Many young women have been tricked into joining extremist organizations.

In addition to putting a huge amount of information on the Internet, extremists will also have one-on-one online and offline contact with the recruits, cultivate feelings and gain trust with the targets, and further encourage young people to go to Iraq or Syria to participate in terrorist activities. There are also members of extremist organizations who even use love as bait to lure young women to extremist organizations.

The pressure of extremists returning to Europe to fight terrorism has increased.

The picture shows that after the terrorist attacks in Barcelona, the Spanish Ministry of the Interior raised the expected level of counter-terrorism.

Since the beginning of this year, in the context of the continuous strengthening of anti-terrorism in European countries, the momentum of terrorism in Europe has not diminished, and terrorist attacks have even shown a high incidence. Britain, France, Belgium and even the relatively calm northern and southern Europe have not been spared. Almost all major attacks have extremist organizations behind them. At present, the living space of extremist organizations has been greatly suppressed, and extremists who went to Syria and Iraq have "returned" one after another, which has made many European countries feel tremendous pressure on counter-terrorism. Some experts said that to combat terrorism, European policymakers need to deploy more anti-terrorism forces to prevent the Internet from becoming a tool for spreading extreme ideas, and to prevent the breeding of terrorism through the joint efforts of the government and social institutions.

　　Our reporter Wan Jing

　　In order to further promote the upgrading of economic industries, the state has put forward a supply-side reform plan to improve the quality and efficiency of the supply system. Product quality depends to a great extent on the level of product research and development and innovation, and is reflected in factors such as brand awareness. Therefore, the overall improvement of product quality to be achieved by supply-side structural reform is closely related to the intellectual property system. However, the Blue Book of Rule of Law (2017) recently released by the Chinese Academy of Social Sciences reveals that the overall quality of China’s product supply is not high and the degree of innovation is insufficient. China’s intellectual property rights still have many problems, such as low quality, insufficient protection and high protection cost, which seriously restrict the innovation of enterprises and the improvement of product quality. Therefore, it is necessary to further improve the intellectual property system and promote the realization of the purpose of supply-side reform.

　　Only 4.1% of enterprises invested more than 5 million in R&D.

　　According to the Blue Book of Rule of Law, through the investigation of the average investment in R&D projects of more than 7,000 enterprises, it is found that the majority (67%) of enterprises invest less than 1 million yuan in R&D funds, and only 4.1% of enterprises invest more than 5 million yuan. The investigation on the patent R&D cycle of enterprises shows that 23.2% of enterprises have a R&D cycle of one year or less, 44.1% have a R&D cycle of one to two years, accounting for 67.3% in total; 6.2% are really willing to carry out long-term research and development for more than three years. This shows that most enterprises are unwilling to spend too long on R&D activities.

　　The Blue Book points out that technological innovation determines the core competitiveness of enterprises. Although technological innovation requires capital investment, it will also generate huge returns. The reluctance of enterprises to invest more funds is a problem that needs reflection and improvement in the field of technological innovation. At the same time, the technological innovation ability of a country or enterprise determines the product supply ability to a certain extent. The ongoing supply-side structural reform in China is precisely to find ways to further enhance the core technological ability of China enterprises’ products and comprehensively enhance their brand reputation. Therefore, it is an important task to further improve the intellectual property protection system and help supply-side reform.

　　The number of patent applications is rampant and the utilization rate is not high.

　　The number of invention patent applications in China has maintained a steady growth trend. According to the data released by China National Intellectual Property Administration in 2015, China Intellectual Property Office accepted 1.102 million invention patent applications in 2015, up 18.7% year-on-year, ranking first in the world for five consecutive years. From the perspective of the number of patent applications, it seems that the innovation ability of China enterprises should rank first in the world. However, from the perspective of the quality of patent applications, this is not the case. No matter in the field of consumer goods or high-tech products, there is still a certain gap between the innovation ability and supply ability of China enterprises and their international counterparts. The innovation ability of enterprises in China is not proportional to the increasing number of patent applications.

　　However, the Blue Book of Rule of Law reveals that a large number of patents applied by enterprises have not really been used to improve product quality. According to China’s patent law, the protection period of China’s invention patent is 20 years, and the protection period of utility model and design patent is 10 years. However, in most cases, the patentee will give up the patent halfway. The Annual Report of Effective Patents in China in 2014 shows that the average service life of domestic invention patents is 3.8 years, utility model patents are 3.5 years and design patents are 3.2 years. However, only 0.02% of inventions, 1.1% of utility models, and 0.5% of designs actually reached the longest service life. The above data show that the vast majority of patents applied for in China have not really been put into use.

　　In addition, the implementation rate of patent licensing can also reflect the actual use of patents. From 2012 to 2014, 2,787,707 domestic patents were granted nationwide, and only 56,067 patent licensing contracts were signed, accounting for only 2% of the authorized patents. This data also reflects that most patents have not really been put into use.

　　Therefore, the patent application of enterprises and the product supply capacity of enterprises cannot be directly equated. In fact, in the existing system, the important index to evaluate the scientific and technological innovation ability of the government or enterprises is still the number of patents, such as: enterprises need patents to enjoy many preferential welfare policies; Enterprises need patent indicators to reduce or exempt taxes and apply for high-tech enterprise certification; Many places and units also need patents for talent introduction and talent evaluation. Obviously, applying for a patent can meet various interests. In addition, in many places, in order to strive for an advanced number of patent applications, bonuses are awarded to enterprises applying for patents through so-called incentive measures, which further leads to the proliferation of patent applications.

　　Seven adults think that the level of intellectual property protection needs to be strengthened.

　　According to the introduction of the Blue Book of Rule of Law, 8,938 people were surveyed with the title of "Evaluation of Intellectual Property Protection Level in China". On the whole, 67% of the respondents thought that the level of intellectual property protection in China needed to be strengthened gradually, even 24.4% thought it needed to be greatly strengthened, and only 7.2% thought it was more appropriate. It is not difficult to see from the survey results that the level of intellectual property protection in China needs to be further improved.

　　In fact, what choices do enterprises make — — Are you committed to your own innovation or imitation and plagiarism — — To a large extent depends on the analysis of costs and benefits.

　　For a long time, the level of intellectual property protection in China is too low, which makes many enterprises reluctant to innovate in the process of product supply, but more willing to imitate and copy. In the litigation of damages for patent infringement cases, 97.25% of the cases are subject to the standard of "statutory compensation", and the average compensation amount is only 79,600 yuan. In contrast, the average amount of patent litigation compensation in the United States from 2007 to 2012 was as high as 29.4 million yuan. In trademark infringement cases, the average amount of compensation awarded by the court is 62,000 yuan, which is also out of proportion to the huge efforts made by trademark operators to maintain their brands for a long time. The low amount of compensation for intellectual property infringement cases has contributed to the formation of this situation: innovators need to spend a lot of financial resources and efforts to make a difference in the pursuit of product quality, and infringers can "copy" it at a low cost. Therefore, the imitation trace is heavy in the supply of various products in China, the innovation ability is insufficient, and the number of intellectual property disputes remains high.

　　It is suggested that the punitive damages system should be fully introduced.

　　Supply-side reform is inseparable from intellectual property rights. Only by perfecting the intellectual property rights system can the real supply-side reform be realized. Based on the aforementioned problems existing in the above-mentioned intellectual property system, the Blue Book proposes to improve the intellectual property evaluation system and realize the change of supply side from quantity to quality. In the process of adjusting the patent quality evaluation system, the original patent quantification index should be adjusted to the actual contribution value of patents to improving product supply. Whether it involves the identification of high-tech enterprises, tax relief for high-tech enterprises, reduction of patent application fees, and related incentives for enterprise inventions and creations, it is necessary to cancel the original provisions on patent quantification, and take whether patents are actually used, the use effect, and the actual contribution value to product supply as evaluation indicators. In a series of documents that need to be submitted by enterprises, it is necessary to submit documents that patents play a practical role in product supply besides patent certificates.

　　The Blue Book also suggests increasing the cost of intellectual property infringement and realizing the transformation of the supply side from imitation to innovation. Although the statutory compensation limit was raised from 500,000 yuan to 1 million yuan when the Patent Law was revised in 2008, the existing compensation system still does not have enough deterrent effect on intellectual property infringement, and it is difficult to play an effective guarantee for innovation. Therefore, it is necessary to introduce the "punitive damages system" into the intellectual property law.

　　At the same time, reduce the cost of intellectual property protection and provide legal guarantee for continuous innovation on the supply side. In order to give patent applicants clear expectations and reduce the costs and risks caused by uncertain expectations, it is necessary for the patent law to clearly regulate the patent application cycle. Compared with other types, the process of invention patent is the most complicated because it involves substantive examination. It is necessary for the patent law to clearly regulate the time limit for applying for substantive examination and the time limit for examination results, and if it involves submitting corrected materials, it is also necessary to regulate the time for correction. At the same time, the time limit for the examination results of utility model and design patents is clearly regulated. In this way, enterprises will have a relatively clear expectation and evaluation of future risks in the process of technological upgrading and transformation, and minimize the costs and risks brought by intellectual property applications.

　　Going to bed early in the new year can reduce fat and gain muscle, improve skin and increase hair … …

　　Zhongqingbao Zhongqingwang reporter Xia Wei trainee reporter Chen Ding

　　2020 will be a difficult year for many people, and Lee Eon is no exception. At the age of 25, she joined the work this year and is an employee of a media company. It is not easy for a person to work hard in a big city. She is prepared for hardship and believes that life will get better and better. However, before the days became better and better, her sleep quality became worse and worse.

　　At first, I slept lightly, and I woke up several times intermittently at night. After waking up, I needed an hour or two to fall asleep again. Later, it was difficult for her to fall asleep before zero. Now I even go to bed late for fear of not being able to sleep. Lee Eon occasionally falls asleep unconsciously. When she wakes up, it is still dark outside the window, and her nights are always extraordinarily long.

　　She doesn’t want to take medicine. She sought the help of colleagues and friends around her and received some suggestions. For example, she doesn’t watch her mobile phone for an hour before going to bed, reads books before going to bed, avoids emotional excitement before going to bed, drinks less coffee during the day, and friends who like fitness also suggest that she take time out to do aerobic exercise every day, so as to make her body feel tired. These methods have been tried one by one, but the effect is not significant. "After lying down often, thoughts and pictures begin to surge in her mind, which can’t be suppressed or stopped. It seems that there is a cinema in my head. "

　　Many friends around Lee Eon also suffer from insomnia, and they even set up an "insomnia group", which was originally said to help each other fight insomnia, and later became a "night chat group" when they couldn’t sleep.

　　"I didn’t drink a cup of coffee today, and I’m not going to watch anything with a screen when I get home from work. I hope I can sleep peacefully tonight."

　　Sun Wei, Director of Sleep Department of Peking University Sixth Hospital:

　　Now more and more young people have joined the team of staying up late. What are the hazards of staying up late? First of all, staying up late will affect the quality of sleep. "The ideal time to fall asleep is 11 o’clock in the evening. The proportion of deep sleep is the highest from 11 pm to 1 am the next day. If you often stay up late and miss the best sleeping time, the proportion of shallow sleep and dreaming sleep will be higher, and the quality of sleep will be affected. "

　　Secondly, staying up late often will have an impact on weight. Because staying up late will affect the secretion of human growth hormone. Growth hormone reaches its peak at 11 o’clock in the evening. At this time, if people are asleep, growth hormone will be secreted more. If you are still awake, growth hormone will be under-secreted. Growth hormone can promote the decomposition of fat and the synthesis of protein. Therefore, going to bed early can promote the secretion of growth hormone, thus achieving the effect of reducing fat and increasing muscle.

　　Third, staying up late often will affect skin regeneration, skin will lack luster and elasticity, and people will appear aging. A good sleep is much more important for skin care than skin care products.

　　Fourth, staying up late will also affect hair regeneration. Many young people’s hairline moves backwards, which has a lot to do with staying up late. When staying up late, the concentration of cortisol in human body will increase, and the increase of cortisol will promote the immune response of hair follicle cells, accelerate the programmed apoptosis of cells, lead to hair follicle atrophy, hair loss and affect hair regeneration.

　　Wang Xueqin, Deputy Chief Physician, Department of Sleep Medicine, Peking University Sixth Hospital:

　　Medical research has found that watching blue screen for 2-5 hours before going to bed can reduce the synthesis and secretion of melatonin, hinder the increase of melatonin level, delay sleep time and make sleep shallow. Eliminating blue light is not the key to solve the problem. The best way is not to use electronic equipment before going to bed, turn off strong lighting and improve the public’s concept of sleep hygiene.

　　In Wang Xueqin’s view, often staying up late, pushing back the sleeping time indefinitely, and disrupting the biological clock artificially, these external behaviors are likely to modify genes. In the long run, melatonin will be at a low level for a long time. Melatonin can regulate mood. Dr. Wang Xueqin found that many patients who came to sleep medicine department thought they were just sleeping problems, but they were found to be depressive disorder after examination.

　　Another kind of sleep disorder is becoming more and more common among young people — — "Sleep phase delay syndrome". Dr. Wang Xueqin explained that the sleep phase delay syndrome refers to a pattern that the patient’s main sleep period is shifted back in the 24-hour day and night cycle, usually more than two hours, which is a delay in the start and wake-up time of sleep. The patient can’t fall asleep (wake up) at a desired or conventionally acceptable early time. They have obvious difficulty in falling asleep, but once they fall asleep, there is no obvious abnormality in the quality and quantity of sleep and the result of sleep.

　　When people are deprived of sleep, in order to stay awake for a long time, the body will increase the secretion of orexin and increase food intake behavior. Many people who stay up late will become obese, which may also be related to the increased secretion of orexin. Orexin is not only involved in regulating sleep — — The awakening cycle also regulates physiological functions such as feeding behavior, energy metabolism, insulin secretion and gastric acid secretion.

　　"Sleep beauty sleep is based on science. Good sleep plays an important role in maintaining healthy weight. At the same time, orexin is also involved in brain cognitive activities, so staying up late is not only easy to gain weight, but also may lead to inattention and memory loss. Once the sleep rhythm is changed or destroyed, people often feel the decline of brain function. " Wang Xueqin said.

　　[Keywords: hair loss]

　　This stops the receding hairline.

　　Zhongqingbao Zhongqingwang Trainee Reporter Chen Ding

　　In Song Yi’s impression, hair loss is related to genetics. Song Yi’s parents’ hair is dark and thick, and no relatives at home have lost their hair. According to her parents, when she was a child, the hairdresser would especially help her trim her hair thin. However, this year she began to lose her hair. Get up with a lot of pillows every day, and after washing your hair, the bathroom drain will be blocked by hair. After work, the pressure is much greater, but she still insists on a good schedule, works efficiently during the day, rarely stays up late, and often goes to the gym to exercise for health, and avoids spicy food in her diet. Song Yi said: "I have thought about using some hair growth drugs, but I am worried about what side effects it will have on my body. I only used some shampoo to prevent alopecia, but the effect was not obvious. I really don’t know what to do now. "

　　[Expert advice]

　　Yang Dingquan, Director of Hair Medicine Center of China-Japan Friendship Hospital:

　　The common types of alopecia are androgenic alopecia, alopecia areata and telophase alopecia. Hair loss in resting stage is mainly caused by malnutrition, seasonal changes and other factors, and the number of hair loss can gradually return to normal in 3 to 4 months after the cause is lifted. Alopecia areata is mainly related to factors such as heredity, immunity and mental stress. Generally, it is necessary to go to the hospital for dermatological treatment, find the inducing factors and receive professional treatment, and most of them can be cured. Androgenic alopecia accounts for 95% of alopecia patients, mainly in adult males. In China, there are about 130 million male patients with androgenic alopecia and about 30 million female patients.

　　Yang Dingquan said that androgenic alopecia is mainly characterized by thinning, shortening and softening of the hair on the top of the head, characterized by the backward movement of the front hairline and the decrease of the hair on the top of the head, which eventually leads to baldness, while the decrease of the hair on the temporal side and occipital part is not obvious, which eventually leads to the formation of M-shaped, C-shaped and U-shaped alopecia areas on the top of the head.

　　The causes of androgenic alopecia mainly include heredity, androgen metabolism, mental stress, hair follicle microenvironment and other factors. Hereditarily, androgenic alopecia is considered as a polygenic disease, and about 50% of male androgenic alopecia patients have a clear family history.

　　Excessive testosterone and dihydrotestosterone combined with hair follicles in sensitive areas of the top of the head will lead to long-term shortening, prolonged resting period and slow growth of hair in this area, which is currently considered to be the main cause of androgenic alopecia. "Dihydrotestosterone is in men until they are 18 years old ‘ Do good deeds ’ , to help boys develop into masculinity, such as Adam’s apple development, voice change, long beard, etc., but it begins after men are 18 years old ‘ Do bad things ’ , make people oily, acne and baldness. Therefore, androgenic alopecia’s onset is generally after the age of 18, and some of them even began to lose their hair after changing their voices. " Yang Dingquan said.

　　The third main factor leading to androgenic alopecia is mental stress, often staying up late to work, with great mental stress. Long-term tension, anxiety, depression and anger will lead to fluctuations in hormone levels in the body, which will make the human body produce stress hormones, thus shortening the hair follicle cycle and accelerating hair loss.

　　Hair loss is a disease caused by many factors. Sex hormone level, individual sensitivity and hair follicle microenvironment may all be the conditions for hair loss. "Some people with elevated androgen or staying up late often do not necessarily have hair loss problems. Whether these pathogenic factors will cause the disease varies from person to person. The latest research found that hair follicle microenvironment is also closely related to hair loss, including local microcirculation, infection and inflammation around hair follicles, which have an important impact on the growth cycle of hair follicles, which is also a hot spot in clinical research. " Yang Dingquan said.

　　So how do you judge whether you are losing your hair? Yang Dingquan said that men can press the top of the head with their hands, and then press the back pillow. If they feel that the thickness of hair on the top of the head is thinner than that on the back of the head, they may have hair loss. If women find that their hair falls off more when washing their hair, or there is an obvious "middle point" on the top of their heads, and more scalp is exposed, it means that hair loss is obvious. "There is also a judgment method that many people know, that is, it is normal natural hair loss to lose less than 100 hairs every day. Under normal circumstances, hair loss during shampooing will account for 70% of hair loss throughout the day, so it is normal to lose no more than 70 hairs after washing your head. "

　　Yang Dingquan suggested that if hair loss is mild, you can take home treatment methods such as maintenance, massage and diet health care. You should work and rest regularly, avoid staying up late and feel comfortable. At the same time, pay attention to diet, and eat coarse grains, beans, auricularia auricula, fresh vegetables and fruits, seafood and other foods with high protein content and rich vitamins, as well as crude fiber foods. Eat less sugary foods and avoid irritating foods such as peppers and raw garlic. In addition, anaerobic exercise can also stimulate the secretion of testosterone, so we should pay attention to doing more aerobic exercise.

　　Androgenic alopecia can’t be cured, but effective prevention and treatment can reduce the degree and delay the onset time. If the alopecia is serious, it is recommended to see a doctor, find out the cause of alopecia through blood tests, and then check the degree of alopecia through a hair mirror. Finally, the doctor can check the patient’s alopecia type and then choose a specific treatment method. The drugs used in the treatment include promoting hair growth, adjusting hormone levels, relieving anxiety, anti-infection and improving microcirculation. It is actually a misunderstanding that the use of drugs to treat alopecia will affect fertility. As long as the treatment of alopecia follows the principles of early, long-term, standardized, combined and individualized protection, 90% patients can stop the disease and 70% patients can grow hair.

　　If you are still not satisfied after drug treatment, you can consider doing hair transplant surgery. Hair transplantation is not once and for all. The essence of hair transplantation is the redistribution of hair follicle resources. It is a long-term process to combine "nurturing, transplanting and protecting".

　　"Don’t just believe in the so-called magic quick-acting method for the treatment of hair loss, and don’t trust folk remedies. To treat serious hair loss, you must go to a hospital or a hair specialist clinic or a hair medical center in a regular medical institution for treatment. " Yang Dingquan warned.

　　[Keywords: obesity]

　　The epidemic gave everyone a chance to get fat, and someone seized it firmly.

　　Zhongqingbao Zhongqingwang reporter Maggie Cheung

　　Lin Zhou (a pseudonym), a young man from Wuhan, loves food and doesn’t like sports since he was a child. He is 1.78 meters tall and once weighed about 200 pounds. During the epidemic, because he ate more and exercised less, in June, his weight soared to 556 kg, and his body could not bear it. He lay down uncomfortable and couldn’t breathe. He called 120 for help.

　　The medical staff of Zhongnan Hospital of Wuhan University visited Lin Zhou for nucleic acid detection and pre-hospital examination. The doctor said that obesity led to Lin Zhou’s acute heart failure, which would be life-threatening if not treated in time. After admission, Lin Zhou received various examinations and symptomatic treatment such as color Doppler ultrasound and sleep monitoring. After more than a week, Lin Zhou was finally out of danger and transferred to the general ward.

　　During the epidemic, many people suffered from weight gain. In April this year, a survey conducted by our newspaper on 3,005 respondents showed that 73.7% of the respondents gained weight during the epidemic. Respondents believe that the three main reasons for gaining weight are less exercise, chaotic work and rest, and eating more meals.

　　[Expert suggestion]:

　　Wang Fang, Deputy Director of Cardiology Department of Beijing Hospital and Director of Echocardiography Room:

　　Obesity may lead to a series of complications or related diseases, and then affect people’s life expectancy or lead to a decline in quality of life, which may lead to physical, psychological and social problems. It has been proved that obesity is an important risk factor for cardiovascular disease, diabetes and some cancers.

　　How to judge whether you are obese?

　　There are ways to judge obesity in medicine. Standard weight (kg)= height (cm)-105, obesity degree (%) = (actual weight-standard weight)/standard weight ×100%. Obesity is normal at 10%, overweight at 10%-20%, mild obesity at 20%-30%, moderate obesity at 30%-50%, severe obesity at over 50% and morbid obesity at over 100%.

　　Modern methods to treat obesity include reasonable diet, exercise, behavior and lifestyle adjustment, psychological and social support, drugs and surgery. Among them, lifestyle intervention is very important. A healthy lifestyle mainly includes the following four aspects: reasonable diet and weight control; Proper exercise depends on persistence; Quit smoking and limit alcohol, and benefit endlessly; Stay optimistic and psychologically balanced.

　　A reasonable diet structure needs to control total calories, balance diet and reasonable collocation. "The food we eat is decomposed and metabolized, and then heat is generated for human consumption. The ways of consuming calories mainly include basal metabolism (energy needed to maintain basic activities of life), physical activity and other consumption. When the supply of heat exceeds the consumption, the remaining heat will be stored, and the body is more inclined to turn this heat into excess fat. Eat too much food and consume less; Normal diet, but insufficient consumption in the body may lead to excess fat. Obese people are more than normal weight people ‘ Anabolic ’ More hyperactivity means eating the same food, and the former is more likely to synthesize fat and keep it. " Wang Fang said.

　　Wang Fang emphasized that controlling calorie intake does not mean dieting, nor can it be an extreme way to lose weight by not eating staple food. She said that eating should be based on the principles of: eating breakfast well, eating lunch on time and making dinner as light as possible. Some details need attention, such as trying to slow down the speed of eating and chew slowly; Eat less snacks; Don’t watch TV or mobile phone while eating.

　　Specifically, Wang Fang suggested that women consume 1200 kilocalories a day and men consume 1800 kilocalories, so that there will be no calories left. The reference recipe of 1200 kilocalories is: breakfast, half steamed bread, 250 ml milk; For lunch, 75g of rice, 50g of lean meat, 250g of vegetables and 1 spoon of vegetable oil; For dinner, 75g of rice, 75g of fish, 250g of vegetables and 1 spoon of vegetable oil. The reference recipe for 1800 kcal is: breakfast, half steamed bread, 1 egg and 250 ml milk; For lunch, 1 steamed bread, 100g lean meat, 250g vegetables and 1 spoon vegetable oil; For dinner, 1 steamed bread, 100g of tofu, 250g of vegetables and 1 spoon of vegetable oil; Before going to bed, 250 ml of milk and 3-5 pieces of salty biscuits.

　　"It is worth mentioning that obesity is not only directly related to diet, but also closely related to heredity. The study found that for teenagers under the age of 20, their parents’ weight is normal, and the incidence of obesity in their offspring does not exceed 10%; The parents are obese, and the incidence of obesity in offspring exceeds 70%. Therefore, for the health of our future generations, friends who have not yet become parents should also manage their weight. " Wang Fang said.

　　A healthy lifestyle requires scientific exercise. Wang Fang said that it is not enough to "move". Exercise is a purposeful, planned and repeatable physical activity involving multiple large muscle groups, which aims to promote cardiopulmonary endurance, muscle strength, balance and flexibility. It is not that not lying in bed or sitting still means exercising, and daily activities cannot replace exercise.

　　"The energy consumption of exercise is several times and dozens of times that of quiet. Sitting for 1 hour consumes 80 kcal, walking for 1 hour consumes 180 -200 kcal, and running for 1 hour consumes 500 -700 kcal. " Wang Fang said that the choice of exercise methods varies from person to person, and generally you can choose walking, jogging, tai chi and swimming. Exercise should be appropriate, and it is appropriate not to feel tired after exercise. If possible, exercise for 30 minutes every day, at least 3 times a week.

　　Wang Fang suggested that the exercise should be carried out in a constant, orderly and moderate way. Wang Fang introduced that the intensity of exercise can be judged by the "heart rate estimation method". Generally speaking, people’s heart rate will be maintained at (60-100) beats/minute when they are quiet. The formula of heart rate range of moderate intensity aerobic exercise is: maximum heart rate *(60%-70%), in which maximum heart rate =220- age. For example, for a 45-year-old man, the maximum heart rate is 220-45=175, and the moderate intensity range is 175*(60%-70%)=(105-122) beats per minute. If the man’s heart rate after exercise is in the above range, then he is doing moderate intensity exercise, and if it exceeds it, it is high intensity, and vice versa.

　　Wang Fang particularly emphasized that sports should be scientific and should not be exercised at will. It should be carried out step by step according to everyone’s specific situation, such as age, gender and physique.

　　What can young people do to stay away from myopia?

　　Zhongqingbao Zhongqingwang reporter Maggie Cheung

　　Liu Na is 26 years old and has been wearing glasses for more than ten years. One day in the fourth grade of primary school, my mother found her squinting at TV and asked her if her eyes were uncomfortable. When I went to the hospital for examination, I found that I was nearsighted. Although the degree of myopia has not increased much in recent years, up to now, she has changed more than a dozen pairs of glasses, and the most expensive pair cost more than 3,000 yuan.

　　During the epidemic this year, Liu Na worked at home, staring at the computer every day, lying down and brushing his mobile phone when he was not working. Although he has returned to work, he still often plays with his mobile phone until midnight. "My myopia has deepened, so I came to change my lenses."

　　In China, more than 600 million people suffer from myopia. The White Paper on Eye Health in China released by the National Health and Health Commission on June 5th shows that the overall myopia rate of children and adolescents in China is 53.6%, including 14.5% for 6-year-old children, 36% for primary school students, 71.6% for junior high school students, 81% for senior high school students and 90% for college students.

　　[Expert advice]

　　Wei Wenbin, Vice President and Director of Ophthalmology, Beijing Tongren Hospital:

　　Myopia is closely related to long-term close eye use. Especially during the epidemic, children and adolescents should not only avoid going out for activities, but also study through online classes, which will undoubtedly lead to myopia or deepen myopia.

　　How do children and adolescents use their eyes reasonably? Wei Wenbin suggested avoiding using electronic products and watching TV for a long time. The selection of electronic products should adhere to the principle of "rather big than small", and the order of selection is projection, TV, computer, tablet computer and mobile phone. Non-learning to use electronic products does not exceed 15 minutes, and the cumulative time per day does not exceed 1 hour. After studying online for 30 to 40 minutes, close your eyes and rest or overlook for 10 minutes. Do eye exercises carefully after continuous use of eyes, so that eyes can have a full rest. When reading and writing, keep "three ones", with your hands one inch away from the pen tip, your eyes one foot away from the book, and your chest one punch away from the desk.

　　In addition, we should get rid of bad eye habits. Do not read books or use electronic products when eating or lying in bed, do not read or write in the case of too dim light or direct sunlight, and turn on the room headlights and table lamps at the same time during reading and writing. The table lamps should have sufficient and uniform brightness and color temperature, and books and papers should avoid hardcover coated paper to reduce glare. Screen saver wallpaper with green background can be set to relieve eye fatigue.

　　Wei Wenbin suggested that primary school students sleep 10 hours a day, junior high school students 9 hours and senior high school students 8 hours. We should carefully observe the abnormal situations such as children’s slanting eyes, frequent squinting and eye-squeezing, and go to the hospital if necessary.

　　In April this year, the National Health and Wellness Commission issued the Guidelines for the Prevention of Myopia among Children and Adolescents during the COVID-19 Epidemic, which specifically mentioned that outdoor activities are the simplest and most effective way to prevent myopia, and full exposure to sunlight can effectively prevent the occurrence and development of myopia. Ensure more than two hours of outdoor activities every day; Children and adolescents are encouraged to increase their exposure to outdoor sunlight by walking to and from school, walking out of the classroom during recess, and doing outdoor activities after school in the afternoon and finishing their homework.

　　For children and adolescents who are already nearsighted, Wei Wenbin said that once they are diagnosed with myopia, they should intervene and wear glasses when the degree is greater than 100 degrees. "First of all, we should go to the hospital for identification, and distinguish between true myopia or asthenopia and pseudomyopia."

　　Wei Wenbin reminded that adults who watch electronic screens for a long time may have a deeper degree of myopia, and at the same time cause fundus lesions. This is also the most important cause of blindness. "The deepening of myopia in middle-aged and elderly people may be related to the occurrence and development of cataracts, so office workers should also pay attention to eye care and have eye examinations if necessary to avoid delaying treatment."

　　Guo Xin, Director of School Health Center of Beijing CDC:

　　When reading and writing, choosing a suitable desk is conducive to protecting teenagers’ eyesight and preventing myopia. You can’t use a dining table, dining chair or bed instead. Inappropriate tables and chairs will have a great impact on sitting posture and sight distance, leading to diseases such as myopia and spinal curvature in children. Children and adolescents should be ensured to sit in a chair with their thighs and calves vertical, their backs straight, their upper arms drooping, and their elbows 3-4 cm below the desktop.

　　Meet anxiety? Acceptance, moderate catharsis and positive response

　　Zhongqingbao Zhongqingwang reporter Xia Wei trainee reporter Chen Ding

　　"Anxiety usually comes suddenly, mostly in the middle of the night. At a certain moment when reading a book, brushing a circle of friends or chatting with friends, you will suddenly fall into anxiety, your heart rate will increase, you can’t continue to concentrate on what you are doing, and even sometimes you want to cry." Xu Lu (a pseudonym), 27, is an employee of a foreign company. He said that he used to feel anxious because he had no ideal and goal, but now he is anxious because he has an ideal, but he doesn’t know whether and when it can be realized. "After work, I am always dissatisfied with my present self, afraid to see others finish what I want to do first, and afraid to be compared with others in my field. I don’t want to lose, and I don’t want to spend my life in mediocrity. When the feelings of being unwilling to others are gradually amplified, being stronger becomes anxiety. I often think: when you indulge your anxiety, maybe others are trying, you should act immediately. The more I think about it, the more anxious I am. "

　　Contrary to Xu Lu, Cao Shu (pseudonym)’ s anxiety is "doing something he doesn’t like but doesn’t know what he really wants to do." Cao Shu is 23 years old. His first job after graduation was chosen for him by his parents, but he has no interest in it at all. "There was a lot of workload and pressure for a while, and I had to work overtime until late at night almost every day. In my dream, I was either making a report or quarreling with my leaders and colleagues. After waking up, I felt my mind was blank in bed. Later, I resigned without consulting my parents. "

　　After resigning, Cao Shu had several stormy quarrels with his parents. After the quarrel was exhausted, he locked himself in his room and listened to his father shouting through the door, "What are you doing?" After a few days of calm, he decided to study abroad, but then he met with an epidemic and his study abroad plan was put on hold. "I am often anxious because I don’t know what to do in the future. I don’t have a clear goal, and I don’t want to do things that I don’t want to do against my will. I always feel that anxiety will haunt me until I find my way and prove myself. When you are anxious, you will suddenly feel at a loss, and you can’t continue to do anything. You always feel down-to-earth and restless in your heart. Even remembering that feeling at this time will feel painful. "

　　[Expert suggestion]:

　　Shi Chuan, Director of Clinical Evaluation Center of Peking University Sixth Hospital:

　　The core of anxiety is uncertainty, not knowing what will happen. Anxiety can be manifested as fear or various physical symptoms.

　　There are various forms of anxiety, which can be divided into mental anxiety and physical anxiety in performance, and chronic generalized anxiety and acute panic attack in attack.

　　Mental anxiety is manifested as excessive mental worry and generalization. Because the spirit is in a tense state for a long time, the individual will be easily provoked, angry and angry, and it will affect the individual’s brain’s understanding and judgment of the world, and it will lead to inattention and easy distraction. Long-term anxiety will make the brain in an abnormal active state, which will lead to insomnia. Insomnia will cause new problems, such as memory loss and slow response.

　　Anxiety can also produce a series of physical symptoms, such as palpitation, tightness in the chest, dry mouth, frequent urination, sweating, and even feeling breathless or excessive panting. Muscles will also show a particularly tight phenomenon, which is easy to ache and even tremble. Acute anxiety, also known as panic attack, is manifested as: suddenly feeling flustered, chest tightness, sweating, feeling out of control, and even having a sense of dying. The onset time of acute anxiety is relatively short, generally lasting for several minutes or more than ten minutes, and the longest time will not exceed one hour, which is characterized by sudden onset and sudden termination.

　　Anxiety actually has its function and significance. Anxiety is a kind of stress response when human beings face major events such as illness and disaster, and it is a normal phenomenon. In fact, it is an epidemic prevention function that the organism itself should have, and when it encounters a major event — — For example, this COVID-19 epidemic — — Anxiety is a normal reaction of people, and it is a protective mechanism of the body.

　　Yang Fude, Party Secretary of Beijing huilongguan hospital:

　　Everyone will have some negative emotions such as anxiety and worry after experiencing major negative events, which are normal. We should accept and allow ourselves to have these emotions and vent them appropriately. In the face of pressure, we can take some positive measures, such as living in a stable place, eating regularly and resting on time. Maintaining daily life and a stable psychological state helps to reduce stress. A stable psychological state can be achieved by some stabilization techniques, such as deep breathing relaxation, music relaxation, meditation training and so on. Taking positive coping styles also includes living a regular life, getting good social support, communicating with trusted people such as family and friends, and doing something that interests you or makes you feel happy. At the same time, everyone should pay attention to avoid negative coping, don’t drink too much, smoke, take drugs, and don’t overwork and sleep too much.

Students from No.4 Primary School in Hezuo City, Gannan Tibetan Autonomous Prefecture are taking part in painting interest classes.

　　Cctv news(Reporter Wang Xiaoying) Learn Chinese calligraphy, mandolin and electronic organ … … Nearly 30 interest classes have enriched the students’ after-school life in the fourth primary school of Hezuo City, Gannan Tibetan Autonomous Prefecture.

　　Founded in 1984, No.4 Primary School in Hezuo City, Gannan Tibetan Autonomous Prefecture, now has 1283 students, 69 Tibetan teachers, 23 Han teachers and 6 Hui teachers. It is a full-time boarding primary school with Tibet as the main teaching mode.

　　Tashi, who is in the fifth grade, has studied Tibetan calligraphy for a year, and he is going to learn Chinese calligraphy recently. Just like Tashi, most of the children in this school have their own interest classes.

Tashi, a fifth-grade talent, is learning Tibetan calligraphy.

　　In order to enrich students’ spare time life and cultivate students’ interest, the school established the Rural Children’s Palace of the Fourth Primary School in Hezuo City. According to the existing conditions and students’ age, cognitive and psychological characteristics, nearly 30 interest groups have been established, such as instrumental music, Tibetan and Chinese calligraphy, chess, painting, dance, mandolin and football, and game activities such as sandbag and skipping rope have been carried out in the lower grades.

　　Zhang Hongrong, the principal of the Fourth Primary School in Hezuo City, said that the Children’s Palace provides concentrated counseling every Tuesday and Thursday afternoon according to the requirements of meeting the needs of students at school first and then radiating students from surrounding rural areas. At the same time, every day from 5 pm to 6 pm, all the function rooms of the rural children’s palace are open, and after-school activities are widely carried out for students, which is well received by parents.

　　It is understood that some of the four primary school students are children of the surrounding herdsmen and migrant workers. Zhang Hongrong said that herders are paying more and more attention to their children’s education, and many herders are even willing to go to the city to accompany them. The activities of the rural children’s palace are also very popular.

　　Zhang Hongrong said that the school attaches great importance to the education of national unity, puts the education of national unity on the important agenda of the school, and draws up the "Implementation Plan for the Education of National Unity in the Fourth Primary School of Hezuo City", which makes careful arrangements for how to carry out the education of national unity in the school. For example, teachers should teach students to respect national customs and establish a strong sense of national unity from the differences in clothing, architecture and diet between Han and Hui.

　　In Zhang Hongrong’s view, letting students know the traditions and cultures of all ethnic groups from an early age, and integrating ethnic customs, the innovation of China by all ethnic groups, etc., has established the concept of children’s national unity in a subtle way.

　　In 2013, the school won the title of Gannan National Unity and Progress Demonstration Education Base, and in 2015, it was rated as a model collective of national unity by the Gansu Provincial Party Committee and the provincial government.
