CCTV News:Dongfeng Village is located in the east of Changming Township, daxin county, Chongzuo City, Guangxi Province. The geographical location here is remote and the traffic is inconvenient; The per capita arable land is less than one mu, and the industrial structure is single. In 2015, Dongfeng Village was listed as a poverty-stricken village in Guangxi during the 13th Five-Year Plan, and then Zhu Xinhua accepted the appointment and came here as the "first secretary".

Poverty alleviation focuses on precision. After Zhu Xinhua took office, he first conducted in-depth research in the local area. In just one week, he traveled to 10 natural villages and 15 villagers’ groups, and made a file, set up a card and accurately identified them. Through the research and analysis of problems and dilemmas, the working idea of "changing ideas, strengthening foundation and promoting industry" is put forward, and the road of breaking the ice to help the poor is embarked.

Improve the facilities, lay the foundation, transform the old look and give it a new look

There is a saying that "if you want to be rich, build roads first". The infrastructure construction in Dongfeng Village has been seriously lagging behind for many years. When Zhu Xinhua first came here in 2015, only one of the ten villages in Dongfeng Village, where the village committee was located, had a cement road to the outside world, and the rest were mud roads. Due to the backward transportation and high transportation cost, the agricultural and forestry products in the village could not be shipped, and no one came to buy them.

In order to change this backward appearance, Zhu Xinhua wrote the Implementation Plan of Poverty Alleviation Project in Dongfeng Village through in-depth investigation, and detailed planned the key construction projects in Dongfeng Village in recent three years. At present, the hardening of the 40-kilometer Tongtun road with an investment of 18 million yuan has started construction; Organize the "one thing, one discussion" financial reward and compensation method, and implement road hardening in five villages in Dongfeng Village; The cultural square and stage of the village Committee with an investment of 400,000 yuan have been completed; The safe drinking water project for people and livestock was implemented, ending the history of three villages without safe drinking water; At the same time, 35 solar street lamps were installed in Tun. Speaking of this, a local village chief was very excited: "Dongfeng Village is undergoing earth-shaking changes, and the villagers are very confident in their future development. Some villagers who work outside the home are planning to come back and develop."

Seek development according to local conditions, explore industries and promote poverty alleviation

Strengthening infrastructure is only the first step in poverty alleviation. The key to effectively increase villagers’ income lies in industrial support. Local farmers have long relied on scattered cultivation of sugarcane, corn, kudingcha, star anise and other cash crops as their income sources. Small industrial scale, low added value of products and asymmetric market information limit the development of village collective economy and the growth of farmers’ income. The choice of industrial projects has become the key to "breaking the ice" in industrial development.

After in-depth investigation, Zhu Xinhua combined short, flat and fast projects with medium and long-term projects, and chose to implement three major projects in Dongfeng Village according to local conditions. The first project is the improvement of Kuding tea and the construction of processing plant. The processing and sales of Kuding tea are still one of the main economic sources in the village, but because of the lack of industrialization, most of the products are hand-processed at home, and the quality is low and difficult to guarantee, and farmers benefit little. In order to change this situation, Zhu Xinhua actively communicated with the county poverty alleviation office, invited superior experts to the village to hold a training course on Kuding tea improvement technology to teach the majority of tea farmers, and applied for Kuding tea improvement funds at the same time, which further improved the quality and output of local tea through technical improvement. In addition, he also won the project fund of 1.5 million yuan to build a Kuding tea processing factory in Dongfeng Village, to build its own brand of Kuding tea products, to increase the added value of products and increase the income of tea farmers.

In addition to traditional planting projects, Zhu Xinhua also draws lessons from the successful experience of neighboring poor counties, and guides local villagers to vigorously promote the planting of macadamia nuts by means of "farmers+bases+companies". At present, villagers have been organized to plant 600 mu of nut saplings, effectively realizing the "combination of long and short" of planting industry and ensuring farmers’ income increase.

With good products, it is more necessary to use new technologies to transform the supply and marketing model. With the efforts of Zhu Xinhua, the "E-commerce Rural" project has established a rural e-commerce service network in Dongfeng Village. Taking the "Internet+Agriculture" express train, the circulation of agricultural products is faster, and the effect is more obvious, which promotes the opening of the market for special agricultural and sideline products such as kudingcha and star anise in Dongfeng Village and even the whole Changming Township. Farmers’ income-increasing channels are wider. On the way to becoming rich, Dongfeng Village has become faster and faster, and more confident.

At present, artificial intelligence and quantum computing have long been hot research topics in their respective fields.

With the continuous development of artificial intelligence technology, artificial intelligence technology, as a strategic technology leading this round of scientific and technological revolution and this round of industrial transformation, has become a new engine to promote economic and social development.

In social life, artificial intelligence has been widely used in smart home, smart medical care, smart agriculture, smart manufacturing, smart finance, smart driving and other fields, and its industrialization has achieved remarkable results. In addition, machine learning has gradually revealed its advantages in many complex scientific issues, including cancer detection, extreme weather prediction, and exploration of new exoplanets.

Quantum technology is also a sharp weapon to promote the progress of digital society. Among many scientific achievements in the 20th century, quantum theory is undoubtedly one of the greatest discoveries, which provides a framework for the establishment of various unified theories of modern physics.

Compared with some improved technologies in the current scientific community, quantum technology has a subversive role. What it subverts is the electronic computing that currently occupies the mainstream position, that is, the traditional and mainstream computers still use electrons as the basic carrier. It can be said that quantum technology itself is one of the core contents of digital technology and the core force to promote the digital economy era.

When artificial intelligence meets quantum technology, what kind of future will it show when subversion is superimposed and subverted?

But quantum computing meets artificial intelligence

Quantum AI, as its name implies, is the combination of quantum technology and artificial intelligence, and it is also the application of quantum technology in the field of artificial intelligence. Among them, quantum technology refers to quantum computing technology.

Compared with the 70-year history of artificial intelligence, quantum computing is relatively younger. Although quantum mechanics, as the protagonist of the whole 20th century, directly contributed to the development of information technology such as semiconductor transistors and lasers, the concept of quantum computing was not really born until 1980s.

In 1981, Feynman, a famous physicist, observed many difficulties encountered by ordinary computers based on Turing model in simulating quantum mechanical systems, and then put forward the idea of analog subsystem of classical computers. Since then, quantum mechanics has entered the process of rapid transformation into real social technology, and human beings are marching faster and faster on the road of quantum computing application development.

Generally speaking, quantum computing is a new computing mode that follows the laws of quantum mechanics to regulate quantum information units for computing, which is completely different from the existing computing mode. Classical calculation uses binary digital electronic method to operate, and binary is always in a certain state of 0 or 1.

Quantum computing, by virtue of the superposition characteristics of quantum mechanics, can realize the superposition of computational states, that is, it includes not only 0 and 1, but also the superposition state in which 0 and 1 coexist. In addition, coupled with the characteristics of quantum entanglement, quantum computer will theoretically have faster processing speed and stronger processing ability on some specific problems compared with the classical computer that uses the strongest algorithm at present.

In October 2019, Google announced the use of 54 qubit processors Sycamore in the journal Nature, realizing quantum superiority. Specifically, Sycamore can complete the specified operation in 200 seconds, while the same amount of calculation on the world’s largest supercomputer Summit will take 10,000 years to complete.

In 2020, China team announced the advent of the "Nine Chapters" of quantum computers, challenging Google’s "quantum hegemony" to achieve global leadership in computing power. As a quantum computer with 76 photons and 100 modes, Chapter Nine is 100 trillion times faster than the fastest supercomputer "Fuyue" at present. For the first time in history, the performance of a quantum computer built by photons surpassed that of the fastest classical supercomputer.

When quantum computing meets artificial intelligence, the computing power of quantum computing will bear the brunt of the development and breakthrough of artificial intelligence. In fact, a major feature of artificial intelligence’s demand for computing power is the parallel computing of massive heterogeneous data, which is difficult for traditional CPU chips. Therefore, this has become the reason why chips such as GPU, FPGA and ASIC are so popular in the field of artificial intelligence.

As mentioned above, quantum computing has parallel computing ability and information carrying capacity that classical computing technology can’t match. In the foreseeable future, although the quantum computer will not completely replace the classical computer, it will rely on its unique advantages in parallel computing, quantum behavior simulation, etc., and play a role in specific scenarios with extremely high computing power requirements.

At the same time, the super computing power of quantum computing comes from quantum parallelism, so it is very suitable for parallel computing needed by artificial intelligence. On the contrary, when quantum computers are gradually pushed into public view, more intelligent machine learning algorithms are also needed to "adapt". It can be seen that the meeting of quantum computing and artificial intelligence will inevitably promote the further development of quantum computing and artificial intelligence.

When subversion overlaps subversion

If machine learning relies on the high parallelism of quantum computing to further optimize traditional machine learning is the most important application of quantum computing in the field of artificial intelligence. Then, the derivative application of quantum computing in artificial intelligence will further realize the current application breakthrough of artificial intelligence.

For example, in artificial intelligence, game theory is widely used, especially in distributed artificial intelligence and multi-agent systems. When quantum expansion and game theory are combined to form quantum game theory, it will provide a new tool for solving problems in the development of artificial intelligence. Quantum game theory models the game phenomenon through the cognitive decision-making process, and studies and describes the game phenomenon and its countermeasures with the help of relevant methods of quantum mechanics theory.

In 2016, Google’s company DeepMind’s Alpha Dog was born based on quantum game theory. Alpha Dog beat Li Shishi, the world’s top Go player, in the first year of its release, and beat Ke Jie, the world’s number one, the next year, bringing artificial intelligence to a new climax.

For another example, in the semantic analysis of natural language, whether using artificial intelligence technology or quantum technology, the mathematical structures of the two are similar in some places. In other words, quantum algorithm is extremely suitable for analog subsystem. Ambiguity can be expressed by superposition, which means that the processing speed can be greatly improved by quantum computing in natural language processing.

In addition, in the field of artificial intelligence, pattern recognition is a particularly important field. For example, identify objects. However, researchers of artificial intelligence often only consider identifying and distinguishing classic objects.

In recent years, with the continuous development of quantum computing and the increasing concern of society, researchers have solved the problem of quantum gate and also studied the resolution of quantum measurement. It is found that through an optimal protocol design, rapid identification can be achieved with the least number of queries, and the resolution of quantum operations is thus well reflected.

Of course, in turn, artificial intelligence can also help solve complex quantum problems. For example, synthesizing drugs and dealing with different chemical reactions are difficult to simulate by solving quantum equations, but some problems can be solved by artificial intelligence. Another example is to solve the ground state energy problem of quantum multi-body Hamiltonian, and artificial intelligence can also be used.

Whether applying quantum technology to artificial intelligence to promote the further development of artificial intelligence technology or applying artificial intelligence to solve complex quantum problems, as Moore’s Law is approaching the physical limit, quantum technology as a subversive technology needs to be developed urgently.

Quantum technology takes quantum as the basic unit of calculation, which revolutionizes the computing architecture with electrons as the basic unit. Firstly, it can improve the security of information communication, and secondly, it can improve the computing power, so that it can be widely used in more industries. It can be said that quantum technology is an important force in the digital technology system, and it is also the core force in the digital economy era with the same name as big data, artificial intelligence and blockchain.

Whether Google’s "Platanus acerifolia" or China’s "Nine Chapters", the horn of quantum superiority has sounded. From the perspective of national policy, the Quanum Manijesto of the European Union and the White Paper on the Development of Quantum Computing of the United States both emphasize the application of quantum information in artificial intelligence.

At the same time, with the increasing R&D efforts and investment of major scientific research teams, research institutions and technology giants, the research in the field of quantum artificial intelligence has begun to explode. This can not only promote the development of artificial intelligence, improve the learning efficiency and accuracy of machine learning, but also promote the prosperity of the quantum world.

The future world is a world driven by quantum computing and artificial intelligence. The world outlined by quantum artificial intelligence will be exciting enough, but it will also make the world full of new challenges.

　　CCTV News:On January 4th, the Ministry of Finance, the Organization Department of the CPC Central Committee and the State Civil Service Bureau released the revised Measures for the Administration of Training Fees of Central and State Organs, which revised the original measures in the aspects of training plan management, organization management, classified management of training items and calculation of lecture fees, so as to further promote the construction of the system of practicing economy and opposing waste.

　　The revised new method is quite distinctive in many aspects, such as clarifying the charging standard for lectures, stipulating that the lectures of academicians should not exceed 1,500 yuan per class hour, and the maximum 760 yuan per person per day at the provincial and ministerial levels, emphasizing that "whoever holds the lectures will bear the expenses", not charging the trainees, strictly prohibiting the transfer and apportionment of training expenses, and adding the content of supervision and inspection on whether there is extravagance and waste.

　　The new regulations implement the highest standard of project classification management 760 yuan/person/day.

　　The training management measures implemented on January 1, 2014 stipulate that the training fees shall be subject to comprehensive quota standards, itemized approval and total amount control. The comprehensive quota standards are accommodation fee 180 yuan/person/day, food fee 110 yuan/person/day, venue fee and lecture fee 100 yuan/person/day, information fee, transportation fee and other fees 60 yuan/person/day, and the total is 450 yuan/person/day. Training within 15 days is controlled according to the comprehensive quota standard; Training exceeding 15 days shall be controlled according to 80% of the comprehensive quota standard; More than 30 days of training, more than days in accordance with the comprehensive quota standard of 70% control. The above days include the check-in and evacuation time, and the check-in and evacuation time shall not exceed 1 day respectively.

　　Compared with the provisions of the 2014 version, the new method clearly implements the classified management of training projects and adjusts the comprehensive quota standard in conjunction with conference fees. According to the requirements of "Regulations on Cadre Education and Training" classification and full-time training, the training programs are divided into three categories, which are applicable to provincial and ministerial level personnel, department-level personnel, division-level personnel and below. Considering that the training of central and state organs is basically held in Beijing, the original 180 yuan accommodation fee standard is difficult to meet the needs. According to the changes in market prices and the adjustment of conference fee standards, the comprehensive quota standard for training fees is appropriately raised.

　　The lecture fee is not more than 1,500 yuan/class hour for well-known experts.

　　According to the new regulations, the teacher fee refers to the expenses incurred by hiring teachers to teach, including the teacher’s lecture fee, accommodation fee, meals fee and inter-city transportation fee.

　　In the old regulations implemented in 2014, the provision that the charging standard for lecture fees is "calculated by half a day" is not accurate enough, and in actual implementation, one or two class hours are also calculated by half a day. This revision is linked with the provision of "Regulations on Cadre Education and Training" that the calculation unit of lecture fees is adjusted from "half a day" to class hours, and the standards are as follows:

　　Deputy senior technical title professionals do not exceed 500 yuan per class;

　　Professional staff with senior technical titles shall not exceed the maximum of 1000 yuan per class hour;

　　Academicians and nationally renowned experts generally do not exceed 1,500 yuan per class hour.

　　This standard is reduced by half compared with the standard stipulated in the 2014 version of the method. At the same time, it is stipulated that the lecture fee shall be calculated according to the actual class hours, with a maximum of 4 class hours per half day. If multiple classes are taught at the same time, the lecture fee will not be calculated repeatedly.

　　No fees may be passed on to the trainees, and offenders will be transferred to judicial organs.

　　In terms of training plan management, the new method, while reiterating that the annual training plan of each unit is reported to the Central Organization Department, the Ministry of Finance and the State Civil Service Bureau for the record, emphasizes that the temporarily added training items must be reported to the main responsible comrades of the unit for approval, and provide the approval materials for the main responsible comrades of the unit when reimbursing. At the same time, in the supervision and inspection, the content of "whether the temporary increase training plan is reported to the main responsible comrades of the unit for approval" has been added.

　　In terms of training organization and management, the new method emphasizes that "whoever holds the training will bear the cost" while reaffirming six "no" and five "no" prohibitions on training contents, meals, activities, etc., and it is forbidden to charge participants, transfer and apportion training expenses, and increase the content of supervision and inspection on whether there is extravagance and waste.

　　It is understood that the Central Organization Department, the Ministry of Finance, the State Civil Service Bureau and other relevant departments will supervise and inspect the training activities of various units and the management and use of training fees. For violations of the new measures found in the inspection, the relevant departments will order them to make corrections, recover funds and notify them; The relevant responsible personnel shall be given disciplinary sanctions according to regulations; Those suspected of violating the law shall be handed over to judicial organs for handling.

　　Official standard of travel expenses: National staff stay in Beijing for one night without exceeding 500 yuan.

　　The Detailed List of Accommodation Standards for Staff of Central and State Organs Traveling to Local Areas, which came into effect in May 2016, stipulates that the accommodation standard for ministerial officials traveling to Beijing is limited to 1,100 yuan per day, while that for bureau-level officials is limited to 650 yuan and that for others is limited to 500 yuan per day. Ministerial officials go to Tianjin, Hebei, Shanxi, Inner Mongolia, Liaoning, Dalian, Jilin and other places, and the daily limit of accommodation fee is mostly 800 yuan.

　　In Zhangjiakou City, Hebei Province, Qinhuangdao City, Sanya City, Hainan Province and other places, during the peak season, the maximum daily limit of accommodation for ministerial officials on business trips rose to 1,200 yuan. The specific implementation standards are as follows ↓ ↓

From the sudden death of a young actor when recording a program, to the sudden death of a college student on the court, and then to the sudden cardiac arrest of Zhang Jingjing, a nurse who helped Hubei Province in Shandong Province, who died after being rescued … The sudden death of young people is frequent, which makes the "sudden cardiac death" attract social attention. September 12th this year is the 21st "World First Aid Day". Recently, the report "Investigation on College Students’ Public First Aid Cognition and Use of Emergency Equipment" led by Lian Si, a professor and doctoral supervisor of university of international business and economics National Institute of Opening to the Outside World, was published. The report shows that young students have a strong awareness of the risk of sudden death, and they have a strong desire to learn and grow up in the knowledge of cardiopulmonary resuscitation (CPR) and the use of automated external defibrillator (AED). However, the awareness rate of relevant knowledge and skills is low, and the ability of emergency rescue is obviously insufficient.

Lian Si told the reporter of China Youth Daily and China Youth Network: "As far as the whole society is concerned, young people, especially those born after 1990s with high academic qualifications, often have high self-demands and expectations. However, while Excellence has become a habit, it has also become a problem that cannot be ignored. "

Because most sudden cardiac deaths occur outside medical institutions, such as families and public places, most of the first witnesses are not medical professionals. Therefore, mastering more first-aid skills may be able to successfully save lives and reduce the degree of injury at the scene.

Over 90% of the respondents hope to learn the knowledge of cardiopulmonary resuscitation, and less than 5% can fully master it.

The Investigation Report on College Students’ Public First Aid Cognition and Campus AED Popularization (hereinafter referred to as the Report) written by Lian Si’s research group shows that 58.13% of the college students surveyed are most worried about myocarditis/sudden cardiac death syndrome, which is much higher than other diseases. Among all the first-aid knowledge categories, 61.46% of the college students surveyed said they wanted to know the knowledge of cardiopulmonary resuscitation most. 92.57% of the respondents thought it was "very necessary" and "relatively necessary" for the school to organize students to systematically learn the knowledge about cardiopulmonary resuscitation, but only 4.86% could fully master the knowledge about cardiopulmonary resuscitation.

"Based on this situation, it is very necessary to strengthen young people’s understanding of first aid knowledge and improve their ability to control related equipment." Lian Si said that promoting first aid knowledge and AED operation skills among young people can effectively reduce the mortality rate of sudden cardiac death, significantly improve the success rate of rescue of critical and severe heart diseases, and minimize the threat of sudden death to life; On the other hand, young people have a strong sense of social responsibility. They have learned first aid knowledge and AED operation skills, which can promote the formation of a good public first aid atmosphere in the society, guide the public to actively share first aid knowledge and skills, and finally form a social atmosphere in which all the people will know first aid and dare to save.

Bad living habits increase the probability of sudden death of young people, and the survival rate of those who are successfully rescued within "golden 4 minutes" can reach 32%

"Traditionally, people think that sudden death is a geriatric disease and has little to do with young people. However, in recent years, data show that young people are also high-risk people. " Hu Zhicheng, a member of the research group and attending physician of the Department of Cardiology, Fuwai Hospital, China Academy of Medical Sciences, said that the main cause of sudden cardiac death among young people is organic heart disease. Electrolyte or acidolysis imbalance, stress or mood fluctuation also significantly increase the probability of sudden cardiac death in patients with organic heart disease. In extreme cases, severe electrolyte or acidolysis imbalance, stress or emotional fluctuation itself can also lead to sudden cardiac death. Many congenital or hereditary diseases are more common among young people.

"In addition, young people often stay up late, and the proportion of unhealthy living habits such as smoking and drinking is high. In addition, the fast pace of life and the pressure of work and study make the electrolyte or acidolysis balance disorder, stress or mood fluctuation frequent." Hu Zhicheng said.

"Cardiac arrest is the main cause of sudden cardiac death." Hu Zhicheng introduced that the rescue time of cardiac arrest is extremely short, and the success rate of rescue is directly related to the start of rescue time. In the event of cardiac arrest, timely and effective cardiopulmonary resuscitation is very important. The survival rate of patients successfully rescued in "golden 4 minutes" can reach 32%, and the survival rate of patients will decrease by 7%-10% for every 1 minute delay in rescue time. Only by giving effective first aid to patients in the "golden 4 minutes" can the mortality rate of patients with cardiac arrest be significantly reduced.

"If a person with cardiac arrest is found outside a medical institution or in a place without defibrillation equipment, he should immediately call for help and quickly start cardiopulmonary resuscitation by hand; If you are in a medical institution or a place with defibrillation equipment, you should quickly obtain a defibrillator to check the patient’s heart rhythm. If you meet the defibrillation indications, you should immediately defibrillation, and strive to get the most effective treatment in the shortest time and improve the patient’s survival rate. " Hu Zhicheng said.

Hu Zhicheng said that the "instantaneous death" of sudden death did not have a clear warning signal before it happened. Even if there were so-called warning signals, most of them were not typical. However, if you have chest tightness, chest pain, breathlessness, palpitation, toothache, jaw pain and discomfort, left shoulder, left upper limb, back pain, or blackness, transient disturbance of consciousness, aura of syncope and other symptoms related to activities recently, you need to see a doctor in time to make sure your heart state.

Create an atmosphere of "can save, can save and dare to save", so that everyone can become the guardian of life.

China Cardiovascular Disease Report 2018 released by the National Cardiovascular Center estimates that there are 544,000 cases of sudden cardiac death in China every year, with an average of 1,490 people suffering from sudden cardiac death every day. However, in the huge sudden cardiac death, the success rate of out-of-hospital rescue is less than 1%.

The report of Lian Si’s research group shows that the lack of first aid knowledge is one of the reasons why college students are unwilling to participate in on-site first aid. When encountering an unconscious person who has stopped breathing, 68.33% of the respondents choose to "dial 120 and wait in the same place", and only 25.76% can "go to check immediately and take first aid measures".

"In this society with increasing uncertainties, any artificially controllable risk factor is the object of our efforts to reduce. Medical first aid requires not only the courage to stand up, but also certain first aid skills and experience. In the face of AED,’ not using’ and’ not dare to use’ will affect the efficiency of use. " Lian Si said.

The survey found that college students’ willingness to use AED to help the wounded will be improved if they have fully mastered the use of AED, and 90.28% of the respondents said that they are willing to use AED when they have fully mastered the operation knowledge of AED.

The report further shows that even if they know the knowledge about cardiopulmonary resuscitation and AED, college students still have some concerns when helping others in an emergency. The main reason is that they have no confidence in their first aid ability, and they are afraid of making mistakes and need to take responsibility. The research group believes that in addition to the inadequate training and publicity of relevant first aid knowledge, the lack of students’ first aid ability, the imperfect legal system related to on-site first aid and the unclear division of responsible subjects are also important factors leading to the above concerns.

Lian Si said that in order for AED to play an effective role, all groups in society should work together and make joint efforts to contribute to the domestic first aid cause. He suggested that the publicity and education of first aid knowledge should be strengthened; Constantly innovate and expand diversified and diversified forms of education and training; Establish and improve laws and regulations related to first aid at the national level, and encourage the public to be courageous; Actively promote the deployment of AED equipment, accelerate the popularization of the concept of first aid and catalyze the willingness of young people to rescue. "Universities and education departments should act as good propagandists and enlighteners; Medical departments at all levels, the Red Cross and other relevant departments act as good feedback and guardians; Government agencies and judicial organs play the role of good guarantors and legislators, and promote the improvement of contemporary youth groups in national security and first aid health literacy. "

"Only when the whole society has the awareness, atmosphere and skills of first aid, the public will not only" save "and" dare to save "but also" be willing to save "when encountering unexpected situations, thus truly building a good social fashion of" everyone for me, I for everyone "and" everyone learns first aid and first aid is for everyone ",so that everyone can become a guardian of life." Lian Si said.

　　Nowadays, informatization has been deeply integrated into all aspects of China’s economy, society and science and technology, and has become one of the important driving forces for national development. The General Secretary of the Supreme Leader regards the agricultural revolution, industrial revolution and information revolution as three eras: "The agricultural revolution has enhanced the survival ability of mankind and made mankind move from barbarism to civilized society. The industrial revolution expanded human physical strength and replaced manpower with machines. The information revolution has enhanced human brain power and brought about another qualitative leap in productivity. " On February 27th, 2014, the Central Leading Group for Cyber Security and Informatization was established, which fully reflected that the CPC Central Committee attached great importance to cyber information work.

　　China is a cyber power and one of the countries facing the most serious cyber security threats. In order to improve the level of information security, a series of special information security laws and regulations have been promulgated at the national level, such as Regulations on the Security Protection of Computer Information Systems, Administrative Measures for the Prevention and Control of Computer Viruses, and Administrative Measures for the Protection of Information Security Levels. The Cyber Security Law of the People’s Republic of China (hereinafter referred to as the Cyber Security Law), which came into effect on June 1, 2017, belongs to the same rank as the previous National Security Law and the Anti-Terrorism Law, and is of milestone significance for establishing the basic management system of national cyber security. The "Network Security Law" attaches great importance to the linkage mechanism of information security, and emphasizes that the national network information department should co-ordinate and coordinate network operators, industry organizations, key information infrastructure operators and other related parties to jointly do a good job in monitoring, early warning and emergency response of network threats.

　　At 20: 00 on May 12th, WannaCry ransomware broke out all over the world. Once infected with this worm variant, important data files of the system will be encrypted and a high bitcoin ransom will be extorted. Within 5 hours, the attack covered nearly 100 countries and regions including the United States, China and Europe. Within 72 hours, more than 200,000 computers in more than 150 countries and regions have been recruited, and the affected areas include government departments, medical services, public transportation, postal services, communications, and automobile manufacturing.

　　The reason why this virus attack is so harmful is that it uses the "Eternal Blue" network attack tool. Eternal Blue is just one of the 12 cyber weapons released by NSA (National Security Agency) after its recent theft. According to Snowden, there were more than 1,000 such weapons in 2013. Therefore, it can be said with certainty that similar cyber attacks will happen again in the future, which will have an overall impact on China’s network security. In order to effectively attack such "national cyber threats", China should further build a new national information security linkage mechanism under the guidance of the Cyber Security Law.

　　First, to achieve rapid linkage with the goal of "golden 24 hours".

　　In earthquake rescue, 72 hours after the earthquake is called the prime time of rescue. According to statistics, the relationship between rescue time and survival rate after Tangshan earthquake is: 99.3% within half an hour, 81.0% on the first day, 33.7% on the second day, 36.7% on the third day, then it drops to 19.0% on the fourth day and only 7.4% on the fifth day.

　　Network attack tools developed by professional hackers often take advantage of Oday vulnerabilities, so they can be widely spread and destroyed in a short time. However, this kind of large-scale attack will inevitably attract the attention of information security professional organizations, and generally the corresponding solutions can be found within 24-48 hours. Therefore, the key to deal with the "national cyber threat" lies in whether we can seize the "golden 24 hours".

　　The premise of grasping the "golden 24 hours" is to clarify the identification standard of "national cyber threat". Article 51 of the Cyber Security Law stipulates: "The State establishes a network security monitoring, early warning and information notification system. The national network information department shall co-ordinate and coordinate relevant departments to strengthen the collection, analysis and notification of network security information, and uniformly release network security monitoring and early warning information in accordance with regulations. " Launching the emergency measures of "national cyber threat" not only involves a wide range, but also costs a lot to mobilize. Only after the "national cyber threat" is given a clear technical standard can the network security organization test and identify the new threat according to the standard, and report it to the national cyber information department according to the preliminary identified threat level according to the corresponding process.

????Second, with the goal of "end-to-end process", realize the whole process of getting through to the user’s desktop.

　　In the domestic units attacked by WannaCry, most of them have made emergency plans for network security and conducted drills. There are three main reasons why they failed to play their due role: First, the concept is backward, thinking that "nothing will happen with the physical isolation of the intranet", and only taking some temporary measures to cope with the superior inspection, the information security management has not really been put in place; Second, there is a lack of "cross-level" standard process, and there are many decision-making levels, which leads to slow response. Two days after the national network information department has publicly issued an emergency notice, some units still failed to take countermeasures, resulting in unnecessary losses.

　　"End-to-end process" means "starting from the customer demand side and going to meet the customer demand side". Corresponding to the information security linkage mechanism, it is from the discovery of network threats to the completion of the security deployment of each user’s desktop.

　　Article 53 of the Network Security Law stipulates: "The national network information department coordinates relevant departments to establish and improve the network security risk assessment and emergency work mechanism, formulate emergency plans for network security incidents, and organize drills regularly." In order to deal with the "national cyber threat", we should formulate a "national chess game" cyber security emergency plan, including government agencies at all levels, important enterprises and institutions and colleges and universities. After confirming the "national cyber threat", the traditional information transmission mode of "layer by layer communication and decision-making" is no longer adopted, but the front-line network security and operation and maintenance personnel who have filed in advance can get relevant information as soon as possible by means of flat process and informatization, so as to quickly start targeted measures. Because "national cyber threat" is very rare, in order to ensure that the emergency plan can effectively play an "end-to-end" role, we should further strengthen the "actual combat drill", take the low-threat Oday vulnerability as an example, start national emergency measures, and conduct spot checks on the implementation of relevant units.

????Third, with the goal of "capacity sharing", realize the great synergy of network security forces.

　　Complex application software, such as Windows operating system, often has hundreds of millions of lines of code, and logical loopholes are inevitable. Hacker organizations in various countries often trade Oday vulnerabilities and cyber weapons through the Internet, which has achieved "great collaboration" in a sense. For example, the "eternal blue" used in this WannaCry attack was released on the Internet as a free trial by the hacker organization "Shadow Brokers" in order to sell other cyber weapons stolen from NSA at a high price.

　　In order to counter the great cooperation of hackers from various countries, it is necessary to further strengthen the cooperation of domestic network security forces. Article 39 of the Network Security Law stipulates: "Promote the sharing of network security information among relevant departments, operators of key information infrastructure, relevant research institutions and network security service institutions". After the WannaCry attack, most domestic security companies have released their own security patches in a short time, but there are still some differences in response time and protection effect. If a reasonable technology sharing and interest incentive mechanism can be established, when the "national cyber threat" occurs again, the domestic cyber security forces will be able to achieve a faster and more effective response.

　　In addition to the emergency response after the attack, a more active strategy is to find the potential loopholes of ODA before robbing hackers, and to change the thinking mode from "mending after death" to "preparing for a rainy day" and from "pure defense" to "attacking to promote defense", so as to finally realize the great synergy between "cyber attack" and "cyber defense". Article 16 of the Network Security Law stipulates that "the State Council and the people’s governments of provinces, autonomous regions and municipalities directly under the Central Government should make overall plans, increase investment, support key network security technology industries and projects, and support the research, development and application of network security technology". The network attack and defense shooting range is the key to "attack to promote defense". By providing a simulated network attack and defense environment, "white hat hackers" are encouraged to find and block network vulnerabilities before malicious attacks by real hackers. Because most government agencies and national defense military units in China use physically isolated intranets, it is of great significance to build a network shooting range based on classified networks for national security. By making our security defense system and independent application software tested in actual combat, we can speed up the discovery and repair of vulnerabilities, and form a certain degree of "information fog" for external hackers, increasing the difficulty and complexity of their attacks.

　　With the outbreak of artificial intelligence technology, the "great synergy" between machine intelligence and human brain intelligence has become the development trend of network security in the future. Since 2013, DARPA (National Defense Advanced Research Projects Agency) of the United States has launched the Cyber Grand Challenge (CGC). The participating teams are all composed of computers. Without any human intervention, they can automatically identify system defects and vulnerabilities in real time, and automatically complete patching and system defense. In August 2016, at —Defcon CTF, the world’s top event in information security, the winner of CGC, Mayhem Machine Team, staged a man-machine hacking battle with fourteen human teams, and once surpassed two human teams. Artificial intelligence can continuously scan system defects or vulnerabilities faster and more effectively than human teams, and improve the ability to quickly repair these program defects in billions of lines of code. However, due to the lack of human flexibility, it is unable to automatically detect logical vulnerabilities, unable to cope with many more subtle attacks initiated by human hackers, and has a certain probability of causing information security accidents (such as confidential information leakage, server downtime, important file deletion, etc.). Therefore, the future development trend is to promote the collaborative work between AI and human beings, filter out most suspicious information on the network through artificial intelligence systems, and greatly reduce the number of potential threats that need to be dealt with by human experts.

　　The Cyber Security Law is an important embodiment of the country’s overall security concept, which will certainly improve citizens’ awareness of cyber security in an all-round way, and make China’s network safer, more open, more convenient and more dynamic on the basis of ensuring the national interests and the vital interests of the people!

“With you, I feel relaxed and enjoyable

It’s fun to fall if you’re too happy.

I want to be a bird and a fish with you in my heart

Be in the vast sky"

— — With you

　The mobile phone randomly played this song "With You" by Danny Chan, and I saw the following comment: "On September 8, 2017, it seemed that the beauty of the flourishing age never left our sight. As soon as the music started, all kinds of emotions emerged in my heart. The Three Swordsmen in Central, all kinds of time have passed, and they are still teenagers when they return. I don’t want to see you only in my dream. I want to see you when you were young, as if you were sitting in front of me, and the glow sticks and movie tickets I owe you have a chance to make up. " The little emotions buried deep in my heart were suddenly excavated.

Comments of netizens on a music platform

The first time I heard this song, I watched it on CCTV6 movie channel. At first, I looked at Leslie Cheung with my mind. In the end, I was caught by this song of Danny Chan. "With You" is the theme song of the movie "Unemployed Students", starring Danny Chan, Leslie Cheung and Zhong Baoluo.

The film was released in Hong Kong on August 26th, 1981, and there was a wave of watching movies. On September 8 this year, the film will be released in the mainland after being restored. On the latest "restored version" poster, it is the best time for the three of them to freeze. The slogan on the poster, "Returning is still a teenager", is exactly this feeling.

"Starting from scratch"

In the movie "Unemployed Students", Jiabao (played by Danny Chan) and Jiahui (played by Zhong Baoluo) are a pair of biological brothers with superior origins; Ah Rong (played by Leslie Cheung) was born poor and rebellious. The three are classmates’ friends at school, and they will face different choices after graduation. The film tells the story of these three friends who graduated and lost their jobs, and reached the same goal in this graduation season when their dreams and reality collided fiercely.

In the process of working with Arong, Jiabao met her angel, who was played by Jeff, a pure jade girl. Ah Rong’s girlfriend is Mei Bo Kwong, who played the glamorous ghost many times in the 1980s.

*Leslie Cheung, Danny Chan and Jeff.

No matter in or out of the play, Jeff seems to be in perfect harmony with Danny Chan in all aspects, but they are not affected by the play. At that time, Danny Chan preferred actress Weng Jingjing — — I had an affair with Leslie Cheung, and she was also a woman that Danny Chan had always loved. There are even rumors that Danny Chan’s later "I just like you" was written for her.

Danny Chan once said, "It’s difficult for me to find a girlfriend in Hongkong. There are many good girls in my circle, but none of them are in my mind. Like Jeff, she is very painful, but I feel more and more that it is not suitable for us to walk together. On the contrary, Weng Jingjing is very suitable for me. She is pure and pure, so sweet! "

"the fate of hope"

Back to reality, Leslie Cheung, Danny Chan and Zhong Baoluo were the lucky ones in Hong Kong entertainment circle at that time. As soon as I debuted, I was madly sought after by a group of "fans", and I was dubbed that the whole "Central" could not fit. As a result, the three were called "Three Swordsmen in Central" by the media.

In fact, before the movie "Unemployed Students", the three had co-produced a movie — — Cheers. This film was tailored for three people. At that time, Danny Chan was the most popular, and naturally he played the role of first hero. Leslie Cheung played Danny Chan’s opponent, the "villain" in the film, and only appeared in the whole film for more than ten minutes. Zhong Baoluo, a good friend, is a DJ in the play, just like in reality. And the heroine is Weng Jingjing who has been thinking about since Danny Chan.

There is no denying that Danny Chan is the most talented musician among the three. He once wrote theme songs for both films. In 1980, the album "Cheers" of the same name was released simultaneously, which sold amazingly and became the platinum record of that year in one fell swoop; The following year, the film "Unemployed Students" was released, and the theme song "With You" was even more popular in Hong Kong. Even the movie posters advertised that "Danny Chan is crazy in Hong Kong with You".

The movie poster plays "Danny Chan’s song" Crazy Hong Kong with You "as propaganda.

"get together"

After the two films, the careers of the three people are on the right track, and the relationship is closer. At the same time, they are constantly being tested by public opinion.

In 1982, Zhong Baoluo suffered a car accident while filming the TV series "Sweet 24 Flavors". His legs could not move, and his role was forced to be replaced by newcomer Mo Shaocong.

Since then, Leslie Cheung, another protagonist of the same drama, has been in a very bad mood. At that time, Leslie Cheung, Danny Chan, Wan Ziliang, wu wenxiong and other friends held two concerts in the college hall to raise money for his operation. Zhong Baoluo therefore applied to the hospital for attendance, thanking his friends.

During his illness in Zhong Baoluo, Leslie Cheung often visited each other during filming, and always encouraged him: "You! But if you survive, there will be people who will be blessed! As long as you recover, you will be more successful. " Later, Leslie Cheung became the object of Zhong Baoluo’s talk. They also worked together in movies (1982) and (1983).

In contrast, the feelings of Leslie Cheung and Danny Chan are more "dramatic". Both of them are Virgos, and their similar personalities made them close as soon as they debuted. At that time, people often saw the pair of friends entering and leaving the ballroom together.

Leslie Cheung and Danny Chan have always had a good relationship, and they have not been alienated because of the career gap. In 1979, Leslie Cheung released her first solo Cantonese album "Lover’s Arrow", but the market response was flat, even when she performed outdoors, she encountered embarrassing performance feedback. In the same year, Danny Chan released his first album, First Love, and one of them, Tears for You, became the "Top Ten Chinese Golden Songs" in Hong Kong.

It was not until 1983 that Leslie Cheung’s acting career was gradually recognized and became a "strength school" in the true sense. His song "The Wind Keep Blowing" was widely recognized. In the same year, he was nominated for the best actor in the second Golden Awards for his films. The following year, Leslie Cheung became popular in Cantonese with a song "Monica", which was also an episode of the film "Fate" starring Leslie Cheung, Anita Mui and Maggie Cheung.

However, in 1984, the relationship between the two became one of the biggest gossip in Hong Kong. At that time, as long as the media heard a little wind, they began to hype it up and made a fuss about it. In the whole incident, the worst thing is their mutual friend — — Directed by Gao Zhisen. At that time, Gao Zhisen invited them to star in their own film Merry Christmas, but they were so angry that they refused to appear in the same scene.

According to the news after Gao Zhisen, the two men were difficult because they went to the ballroom to play together. Everyone around them praised Danny Chan’s good skin and asked him if he was wearing makeup. Danny Chan confidently said that she didn’t wear makeup. As a result, Leslie Cheung directly picked up a paper towel, scratched Danny Chan’s face, and a powder mark appeared on the paper towel.

At this point, the two brothers entered a "cold war" state. But I think about it, the two brothers are really like children.

To the surprise of a group of "people who eat melons" waiting to watch the excitement, this "small awkwardness" did not last long, and the two soon made up. At Leslie Cheung’s solo concert in 1985, he covered Danny Chan’s song "Cheers" and said before singing, "If we are women, he is Lizhen Yu and I am Li Xiangqin. Let me, Li Xiangqin, sing this song and give it to Lizhen Yu." (Lizhen Yu and Li Xiangqin were famous loyal and treacherous partners in Cantonese Opera at that time. Lizhen Yu usually played a positive role, while Li Xiangqin played more villains. )

Halfway through the song, Danny Chan suddenly appeared on the stage, rushed forward to hug Leslie Cheung and shook his hand. Leslie Cheung said to Danny Chan, "I can sing two lines of your song in every capital, but this one is the most familiar. Can you sing with me?" Finally, the two sang the song together. Finally, when Danny Chan was ready to step down, Leslie Cheung specially told the lighting engineer to give him a light so as not to let him fall. The intimate interaction between the two directly broke the rumor of discord.

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

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

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

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

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

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

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

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

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

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

There are many respiratory diseases in children in winter, among which influenza virus is one of the common pathogens. What are the typical symptoms of influenza? How does the flu spread and how long is the incubation period of the flu?

1. What are the typical symptoms of influenza?
Children infected with influenza virus can show fever, chills, headache, myalgia and other general malaise, often accompanied by respiratory diseases, such as cough, sore throat and runny nose.
The degree of fever in young children may be heavier, and some children may also have febrile convulsions; In addition, they will have more gastrointestinal symptoms, such as nausea, vomiting, diarrhea and poor appetite.
A very small number of children infected with influenza may develop into severe influenza, causing laryngitis, pneumonia, encephalopathy, myocarditis and so on.

2. How does the flu spread and how long is the incubation period?
Influenza virus can spread from person to person through respiratory droplets (such as sneezing, coughing and talking) or after polluting the surface of objects.
Influenza viruses can also spread through small air particles released by influenza patients when they breathe. Influenza patients are the main source of infection.
The incubation period of influenza is generally 1~7 days, and most of them are 2~4 days.

3. How long is the general course of influenza and what is the change of the course?
For children without basic diseases, the course of influenza virus infection is acute and self-limited, and most symptoms disappear within 2~3 days after onset. Some children’s fever lasts for 5 days, and most of them recover within 1 week. However, cough may last for a long time, and the fatigue of a few older children (over seven or eight years old) may last for several weeks.

4. How to distinguish the flu from the common cold?
The full name of the flu is called "influenza", and you may think it is similar to the common cold, but the flu and the common cold cannot be confused.
The common cold can be caused by many pathogens, among which viruses are the most common, including rhinovirus, adenovirus, metapneumovirus, bocavirus, etc. Bacteria and mycoplasma can also cause the common cold.
The symptoms of the common cold are mild, usually low-to-moderate fever, which lasts for 1-2 days, and may be accompanied by symptoms such as sneezing, runny nose, stuffy nose and slight cough, while systemic symptoms such as chills, headache and joint muscle pain are very mild. Generally, there are no serious complications.
Influenza is mainly caused by influenza A and B virus infection, with high fever, shivering, headache, joint muscle pain and other systemic symptoms. A few influenza patients may have complications such as rhabdomyolysis, pneumonia, encephalitis and encephalopathy.
In the flu season, children with flu-like symptoms, especially those with a history of contact with influenza patients, should first consider influenza virus infection, which can be diagnosed by influenza virus antigen detection or influenza virus nucleic acid detection. (Healthy China)
