Wen Jiabao, Prime Minister of the State Council, presided over the 37th executive meeting of the State Council on the 29th to study and deploy the prevention and control of highly pathogenic avian influenza. The meeting decided that the prevention and control of highly pathogenic avian influenza should focus on eight measures.

　　(1) In areas where the epidemic situation has been discovered, it is necessary to timely and accurately announce the epidemic situation in accordance with the prescribed procedures, and resolutely cull, thoroughly disinfect, strictly isolate and enforce immunization in accordance with the requirements of epidemic prevention work, and resolutely prevent the spread of the epidemic situation.

　　(two) in areas where no epidemic situation has been found, we should pay close attention to the work of epidemic prevention and improve the emergency plan for epidemic situation. It is necessary to focus on the epidemic prevention work in key areas, large-scale farms and large-scale breeding professionals, strengthen epidemic monitoring, and take effective measures to prevent the outbreak.

　　(three) the implementation of epidemic prevention funds, clear compensation policy. Reasonable compensation should be given for the loss of culling poultry in areas where highly pathogenic avian influenza occurs, and compulsory immunization of poultry should be implemented free of charge, so that the people can have no worries. The funds required for culling and compulsory immunization according to regulations shall be shared by the central and local governments.

　　(4) Strengthening scientific research. It is necessary to organize scientific and technological research on highly pathogenic avian influenza virus and its prevention and control, rationally arrange the production and storage of highly pathogenic avian influenza vaccine, and actively carry out international exchanges and cooperation in the prevention and control of highly pathogenic avian influenza.

　　(five) to strengthen the quarantine of import and export poultry and their products, to prevent the spread of the epidemic. Severely crack down on smuggling of poultry products. Strengthen the management of poultry market and the detection of epidemic diseases.

　　(six) conscientiously do a good job in the propaganda of popular science knowledge about the prevention and treatment of highly pathogenic avian influenza, so that the broad masses can understand the characteristics and prevention knowledge of the spread of highly pathogenic avian influenza.

　　(7) Resolutely prevent highly pathogenic avian influenza from infecting people. At present, we should focus on medical monitoring and prevention of epidemic areas and high-risk groups.

　　(eight) to establish a mechanism to deal with sudden major animal epidemics. We will step up the establishment and improvement of epidemic monitoring and quarantine networks, and strengthen the construction of animal epidemic prevention infrastructure and grassroots epidemic prevention teams.

The Great Wall is the spiritual symbol of the Chinese nation and the largest and most widely distributed cultural heritage in China. Among the 15 provinces, autonomous regions and municipalities directly under the Central Government where the Great Wall is distributed in China, the Beijing section of the Great Wall is well preserved, but the maintenance is more difficult than expected.

Beijing sets up special funds every year.

　　Emergency rescue and reinforcement of 10 sections of the Great Wall

　　The Great Wall in Beijing was first built in the Northern Qi Dynasty and was built on a large scale in the Ming Dynasty. In history, it was well-guarded and built for guarding the capital, which is the essence of the Great Wall in China. In terms of scope, the Great Wall of Beijing covers six districts, including Pinggu District, Miyun District, Huairou District, Yanqing District, Changping District and Mentougou District, with a total length of 520.77 kilometers.

　　Since 2000, nearly 100 Great Wall protection projects have been carried out in Beijing, including a demonstration protection project represented by the famous dangerous section of the Great Wall, Jiankou Great Wall. In 2019, the "Beijing Great Wall Cultural Belt Protection and Development Plan (2018-2035)" was announced, and the protection and repair of the Great Wall in Beijing was further strengthened.

　　According to the plan, by 2035, by means of emergency rescue and routine maintenance, Beijing will realize that the whole line of the Great Wall itself and its carrier is free from danger. In order to achieve this goal, starting from 2019, Beijing has steadily promoted 10 Great Wall rescue and reinforcement projects every year.

　　Since August this year, the rescue and reinforcement projects of the Great Wall in Beijing in 2021 have started one after another. In late October, the construction also came to an end. Among them, the construction of the Great Wall in Huairou section this year has all ended — — All four municipal projects have been completed, and the fourth phase of the Jiankou Great Wall renovation project has also completed this year’s task.

　　From Jiankou Pass to Zhengbei Building

　　The eastern section of Jiankou Great Wall has been penetrated.

　　This year’s emergency maintenance project of the Huairou section of the Great Wall runs through the most steep part of the eastern section of the Jiankou Great Wall.

　　The Great Wall of Wan Li extends east and west in the spectacular mountains north of Beijing. The Great Wall in Huairou section of Beijing is an important part of it. It is connected to Xiaoshuiyu in Miyun District in the east and Dazhuangke in Yanqing District in the west, with a total length of 65.4 kilometers. Now, every enemy building (platform) in the long section of the city has a number, which increases from No.1 to No.284 from east to west.

　　The Jiankou Great Wall is a part of Huairou Great Wall, which starts from No.122 watchtower of Zhengbei Building in the east and is connected with Mutianyu Great Wall. Northwest to the "Nine Eyes Building" No.169 enemy building, bordering the Great Wall section of Yanqing District. Because of the steep terrain, the Jiankou Great Wall is considered as "one of the most dangerous sections of the Great Wall in China".

　　Taking the "Jiankou Pass" between No.131 and No.132 enemy platforms as the node, the Jiankou Great Wall is divided into two parts in the maintenance project.

　　Among the four municipal projects in Huairou this year, the side wall rescue and reinforcement project between No.130 and No.131 watchtowers is located in the eastern section of Jiankou Great Wall. The elevation of this section of side wall gradually rises from west to east, and the position is steep and steep.

　　The focus of this construction is mainly on the severely damaged floor tiles. According to Zhang Tong, director of Huairou District Cultural Relics Institute, in order to protect the structural stability of cultural relics and prevent them from further collapse, the rescue and reinforcement project has taken measures such as laying bricks or stones to reinforce the parts that affect the structural safety, cleaning and stabilizing them.

　　The construction environment is steep and the construction period is short, which increases many difficulties for emergency rescue construction. Water is needed for construction. However, due to the serious water shortage area, the construction team needs to lay a pipeline with the longest length of nearly 1,000 meters, borrow local 300-meter deep wells to lift water, use diesel to generate alpine pumps, and then lift the water to the top of the mountain through the pumping station. At the end of October every year, the temperature in mountainous areas drops sharply, and the water pipes will face the problem of freezing, so the repair work of the Great Wall will be forced to stop.

　　The cold air came earlier this year. In mid-October, the temperature on the mountain has fallen below freezing point. In order to finish before this, the side wall construction has specially increased manpower. According to Cheng Yongmao, technical director of emergency engineering, the workers are working overtime, going up the mountain at 6: 30 every morning and working until about 5: 30 in the afternoon. "If you go down the mountain later, it will be dark."

　　The rescue and reinforcement project between No.130 and No.131 watchtowers was completed on October 20th. This side wall is connected with the third phase repair section of Jiankou Great Wall. The completion of emergency rescue and reinforcement means that the arrow buckles the eastern section of the Great Wall — — The arrow buckle has been closed to the north building, and the emergency repair has been completed.

　　The fourth phase is affected by continuous precipitation.

　　At present, the clean-up work is completed.

　　In synchronization with the 10 rescue and reinforcement projects of the Great Wall in Beijing this year, on August 13th, the fourth renovation project of the Jiankou Great Wall was officially started, and it is planned to be completed before ice period next year. The renovation scope starts from the well-known "Beijing Knot" (No.154 enemy tower) and goes north to No.162 enemy tower, involving a total of 8 enemy towers (towers).

　　This section of the Great Wall is a masonry structure, with arrow holes on both sides of the battlements, and it is relatively well preserved as a whole. However, the whole section of the wall is overgrown with trees, some walls collapse, the ground is scattered and broken, and the watchtower collapses to varying degrees. The emergency repair mainly includes cleaning up sundries, unblocked drainage, and building collapsed sections. During the construction process, the materials will be transported by agricultural vehicles and mules, and finally they will be carried up the mountain manually.

　　Since the start of construction, the rainfall in Beijing has been constant, which has added more difficulties to the construction. "The construction site is far from the material yard, the road is muddy, and the materials can’t be transported." Cheng Yongmao described it. Therefore, the fourth phase of the project has mainly completed the preliminary cleaning work, and will resume construction after thawing next spring. However, Cheng Yongmao estimates that the fourth phase of the project can be completed on time next year.

　　Before the start of the fourth phase, the repair work of the Jiankou Great Wall has been completed about 3,200 meters. According to calculation, after the completion of the fourth phase of the project with a length of 1678 meters, the repair progress of the Jiankou Great Wall will be nearly half completed.

　　However, the current repair work is mainly an "emergency" for dangerous situations, and it still does not have the conditions for opening to the outside world after completion.

　　"minimum intervention, archaeology first"

　　Respect the traces left by time

　　According to experts, after years of protection and maintenance practice, people have gradually formed the concept of Great Wall protection. In 2014, after National Cultural Heritage Administration issued the Guiding Opinions on the Protection and Maintenance of the Great Wall, these protection principles were further standardized and implemented.

　　In the process of this emergency repair, the construction workers always adhere to the principles of "minimum intervention" and "no change in the original state of cultural relics": in order to maintain the original style, the original old masonry should be used as much as possible for repair; In order to delay the weathering damage of the bottom brick, the vegetation that can be preserved is not easily moved. Zhang Tong said: "After the danger is removed, the structure of the Great Wall will be more stable, but the appearance of the damage caused by wind and frost will not change."

　　Such rescue work has indeed stood the test of years. No.202 watchtower and No.204 gate closure are the emergency and reinforcement projects of the Great Wall in Beijing in 2019. At that time, in addition to mending and strengthening the wall, the construction workers also built an extra low wall to prevent flash floods from directly washing the wall in rainy season. In the continuous rainfall in Beijing in July this year, there was no new danger in this paragraph. Similarly, with the promotion of the renovation project of Jiankou Great Wall, the safety factor of Jiankou Great Wall, which is known as "danger", has gradually improved.

　　The concept of "archaeology first" is gradually integrated into the daily work of emergency repair. In this year’s rescue and reinforcement project, a number of scattered cultural relics, such as roof ridge beasts, launching grates and the bottom of blue and white porcelain bowls, have been cleaned up one after another.

　　From the second phase of the renovation project of the Jiankou Great Wall, the staff added an archaeological cleaning link before the construction, and used archaeological methods to clean up the Great Wall itself and the "one meter and one meter" on both sides to ensure that the scattered cultural relics can be more truly and completely protected. Relevant experts believe that this is an important progress in the concept of protecting the cultural heritage of the Great Wall.

　　Jiankou Great Wall Section

　　The Great Wall section of the arrow buckle is W-shaped, shaped like a full bow, while the arrow buckle at the low point is like a buttonhole for taking an arrow, which is the origin of the name "Great Wall of the arrow buckle".

　　The Jiankou Great Wall has been repaired many times. In 2006, the cultural relics department carried out emergency rescue and reinforcement for Arrow Kouguan, which was threatened by landslide. Since 2016, National Cultural Heritage Administration has successively approved four projects to repair the Great Wall with arrow buttons.

　　In 2017, the first phase of the renovation project of the Jiankou Great Wall was completed, ranging from No.146 to No.150 watchtower (Taiwan), with a total of 1003 meters. From 2019 to 2020, the second and third renovation projects were completed one after another. The second phase of the project was built from No.151 to No.154 enemy building (platform), with a length of 745 meters; The third phase is from No.122 to No.130 enemy building (Taiwan), totaling 1094 meters.

　　The first and second phases of the project are located on the west side of Jiankouguan, and the third phase is located on the east side of Jiankouguan. Before construction started this year, only 135 meters west of No.130 watchtower remained between Jiankou Pass and Jiankou Phase III, so this side wall was included in one of the 10 Great Wall rescue and reinforcement projects in Beijing this year.

　　Extended reading

　　The maintenance section is mostly located in the future open scenic area.

　　Huairou District, where the Jiankou Great Wall is located, contains 284 enemy towers (platforms). Enemy platform No.154 was called "Beijing knot" by the people, and the Great Wall of Wan Li diverged from it, and journey to the south extended to Sihai Town of Yanqing. All the way west to the direction of Juyongguan in Changping.

　　From the "Beijing knot", you can go north along No.154 enemy platform to No.169 enemy platform, which is the famous enemy platform Jiuyan Building at the junction with Yanqing. This section is also part of the Great Wall of Arrow Buckle. The west side of "Beijing knot" is adjacent to No.170 watchtower, one of the four municipal projects in Huairou District this year. If you continue to the west, you can find No.180 and No.185 watchtowers in turn.

　　The Protection and Development Plan of Beijing Great Wall Cultural Belt (2018-2035) defines the spatial layout of Beijing Great Wall Cultural Belt as "one line, five pieces and many points". Among them, the "first line" refers to the Great Wall Line, and the "five pieces" are five core group areas used to relieve the pressure of tourists in the Great Wall Open Scenic Area. The paragraphs repaired in Huairou District this year belong to the Huanghua Road group area.

　　World Heritage Committee spoke highly of the Great Wall protection.

　　At the 44th World Heritage Conference held this year, the World Heritage Committee spoke highly of the positive and effective measures taken by the China government in the protection of the Great Wall, so that the outstanding universal value of the heritage has been properly protected; At the same time, it appreciates the efforts and achievements made by the China Municipal Government in promoting the construction of the Great Wall National Cultural Park, promulgating and implementing the Master Plan for the Protection of the Great Wall, as well as in public communication and promotion, capacity building of heritage sites, special protection legislation, application of modern science and technology, international exchanges and cooperation, and easing the pressure of tourism.

The National Computer Virus Emergency Response Center and Company 360 jointly released an investigation report today (4th), revealing the relevant situation of the CIA’s use of the network to attack other countries, revealing the specific process of some typical cyber security incidents in China and other countries, comprehensively and deeply analyzing the CIA’s cyber attacks and related real harm activities, and its contribution to the United States becoming a "matrix". The release of this report will provide reference and suggestions for cyber attack victims all over the world.

The US Central Intelligence Agency (CIA) is one of the main intelligence agencies of the US federal government. For a long time, the CIA has secretly carried out "peaceful evolution" and "color revolution" around the world, and continued to carry out espionage activities.

In 2020, 360 Company independently discovered a cyber attack organization that had never been exposed by the outside world. The organization used cyber weapons tools associated with the CIA to carry out cyber attacks against victims in China and other countries. The earliest attack activities can be traced back to 2011, and related attacks have continued to this day. The targets of the attack involve important information infrastructure, aerospace, scientific research institutions, petroleum and petrochemical, large Internet companies and government agencies.

The investigation team jointly established by the National Computer Virus Emergency Response Center and 360 Company found that in the massive global cyber attack, the CIA used a large number of "zero-day" vulnerabilities, including a large number of back doors and vulnerabilities that have not been publicly disclosed so far (some functions have been verified), set up "zombie" networks and attack springboard networks around the world, and carried out attacks and intrusions in stages against network servers, network terminals, switches and routers, and a large number of industrial control equipment.

During the investigation of several typical cyber attacks in China, the joint investigation team captured and successfully extracted a large number of Trojan horse programs, functional plug-ins and attack platforms closely related to the CIA from the information network of the injured unit. These related cyber weapons have been subjected to extremely strict standardized, streamlined and professional software engineering management. At present, only the US Central Intelligence Agency strictly abides by these standards and norms to develop cyber attack weapons.

Through empirical analysis, the joint investigation team found that the CIA’s cyber weapons used extremely strict spy technical specifications, and all kinds of attack methods echoed and interlocked. Now it has covered almost all Internet and Internet of Things assets in the world, and it can control other countries’ networks and steal important and sensitive data anytime and anywhere, which undoubtedly requires a lot of financial, technical and human resources support. The American-style cyber hegemony can be seen, and the "matrix" deserves its name.

At present, the joint investigation team has provided relevant information to the public security organs in the jurisdiction where the injured units are located. This station will continue to pay attention to the follow-up progress of this matter. (CCTV reporter Li Wenjie Zhang Gang)
