Preface

　　During the "Thirteenth Five-Year Plan" period, Beijing’s new energy vehicles developed rapidly, the energy supply capacity and service level of new energy vehicles continued to improve, and the industrial ecological system and supporting policy system were gradually improved. The "14th Five-Year Plan" period is the first five years for China to start a new journey of building a socialist modern country in an all-round way and March towards the goal of the second century. It is also a crucial period for Beijing to implement its strategic positioning as a capital city and build a world-class harmonious and livable capital. Charging and replacing facilities for new energy vehicles, including charging piles and power stations, are an important part of the Party Central Committee and the State Council to speed up the construction of new infrastructure. The development of charging and replacing facilities for new energy vehicles is an important content to promote the digital, intelligent, green and integrated development of traditional infrastructure, and to build new infrastructure. It is also an important guarantee to promote the healthy development of new energy vehicle industry and help achieve peak carbon dioxide emissions and carbon neutrality. Strengthening the construction and management of charging and replacing facilities for new energy vehicles is an urgent task to speed up the electrification of motor vehicles at present, and it is also an important measure to improve urban infrastructure, facilitate residents’ travel and promote urban low-carbon development.

　　In order to fully implement the spirit of the State Council’s New Energy Automobile Industry Development Plan (2021-2035), the National Development and Reform Commission and other departments’ Implementation Opinions on Further Improving the Service Support Capability of Electric Vehicle Charging Infrastructure, and Beijing’s Implementation Opinions on Further Strengthening the Construction and Management of Electric Vehicle Charging Infrastructure, This plan is formulated in accordance with the Beijing Urban Master Plan (2016 -2035), the 14th Five-Year Plan for Beijing’s National Economic and Social Development and the Outline of Long-term Goals for the Year 2035, and the Urban Management Development Plan for Beijing during the 14th Five-Year Plan period.

　　Implementation period of the plan: 2021-2025

Chapter I Review of Development during the Thirteenth Five-Year Plan Period

　　(1) Development achievements during the 13th Five-Year Plan period

　　During the "Thirteenth Five-Year Plan" period, Beijing attached great importance to the construction of charging piles and power stations, and the infrastructure for charging and replacing new energy vehicles made great progress. From 2015 to 2020, under the background that the number of new energy vehicles has increased rapidly from 36,000 to 400,000, the number of charging piles in the city has increased from 21,000 to 230,000, and the number of power stations has increased from 5 to 159, forming a good situation of moderately advanced pile stations and coordinated development of vehicles and piles (stations). By the end of 2020, Beijing has formed a social public charging network with an average service radius of less than 5 kilometers in the plain area of the city, in which the charging service radius of key areas such as the central city, Beijing Economic and Technological Development Zone and Yanqing Winter Olympics Area has been less than 0.9 kilometers, basically achieving the planning objectives during the "Thirteenth Five-Year Plan" period, which has played an important role in guiding, supporting and ensuring the popularization and application of new energy vehicles.

　　1. The scale of facilities is leading in China.

　　The overall scale is at the national leading level. By the end of 2020, 159 power stations and 230,000 charging piles had been built in Beijing, including 175,000 private charging piles, 29,000 public charging piles, 19,000 internal charging piles and 7,000 business-specific charging piles. Covering social parking lots, unit compounds, residential communities, as well as postal services, public transportation, rental, sanitation and other fields, it is at the leading level in the country.

　　The level of development in various fields has been continuously improved. In the case that the proportion of fixed parking spaces for private minibuses in the city is about 30%, the proportion of private self-use piles with cars is about 60%. With the strengthening of the construction guarantee of private self-use piles, the willingness of car owners with fixed parking spaces to buy new energy vehicles is greatly enhanced. The internal charging piles in the unit have become an effective supplement to private self-use piles, meeting the basic charging needs of more than 100,000 new energy vehicles, and fully solving the problem of difficult construction of charging piles in residential areas by using workplace charging. The charging efficiency of public charging piles has been continuously improved, and the proportion of fast-charging piles has increased from 33% at the end of 2015 to 65% at the end of 2020, which has promoted the full coverage of charging piles in venues in the Winter Olympics and fast-charging piles in expressway service areas. In terms of business-specific piles, public transportation, sanitation, logistics, leasing and other fields have selected and excavated their own space resources, and built a total of 654 special charging stations and 143 taxi-changing stations, which have been widely promoted and applied through cooperative construction and leasing, basically meeting the operational needs of vehicles in the public service field.

　　2. The industrial structure has initially taken shape.

　　Diversified charging and replacing market. By the end of 2020, the city has more than 170 charging facilities construction and operation enterprises, and gradually formed a diversified charging market with head enterprises such as State Grid Beijing Electric Power Company, TELD, Star Charging, Yiwei Energy and Putian New Energy as the mainstay, supplemented by small and medium-sized enterprises. The number of charging facilities of five head enterprises accounts for more than 70% of the city’s public charging facilities. 159 power exchange stations form the largest city-level power exchange network in the world.

　　Multi-featured business model. Enterprises actively explore and form a multi-featured business model. The first is the private pile sharing business model represented by Star Charging and Chinese third-class enterprises, which provides private pile installation and maintenance services for automobile enterprises and private pile sharing services for users. The second is the whole chain development model of production, sales, construction and operation of charging facilities represented by special calls and star charging enterprises. Third, large-scale operating companies such as State Grid Beijing Electric Power Company and TELECOM rely on user traffic to set up advertising spaces on the charging APP to obtain additional revenue models. Fourth, charging pile+value-added service mode, with charging network as the entrance and additional value-added services such as sales, leasing and maintenance, such as "State Grid Mall", an e-commerce platform launched by State Grid. Fifth, the new energy vehicle power exchange service ecological network formed by power exchange operators represented by AUTO and Weilai, which integrates power exchange service, battery life cycle management, power demand side response and energy storage.

　　3. Strong policy system guarantee

　　Establish an all-round policy system. During the "Thirteenth Five-Year Plan" period, Beijing has successively issued more than 20 policy documents, basically forming an all-round policy service system covering planning, construction, operation and safety management. The policy coverage ranks first in the country, and the policy synergy effect is gradually emerging.

　　Realize "three firsts" throughout the country. First, it is the first in the country to provide financial support for the construction of internal charging facilities in the unit and encourage opening to the outside world, giving full play to the integrated advantages of convenient internal charging and public services. Second, it is the first in China to implement and continuously optimize the operation subsidy policy with comprehensive operation as the main evaluation index, and guide enterprises to actively improve their operation and management capabilities, improve service efficiency and service level, and the facility failure rate continues to decline. Third, in combination with the self-discipline requirements of China Charging Alliance logo (testing, certification) evaluation and other industries, it is the first in the country to issue the management measures for safety production of charging and replacing facilities, guide charging and replacing facilities enterprises to establish and improve the safety production management system, formulate safety inspection plans year by year, and entrust a third party to carry out special safety inspections to build a solid foundation for safety.

　　Form a local standard system that adapts to the characteristics of the capital. The Standard for Planning and Design of Charging Infrastructure for Electric Vehicles (DB11/T 1455-2017) was issued, which clearly defined the planning and layout, construction site selection, allocation and construction index, site design, facility design, electrical design, energy utilization and information system of charging infrastructure, and unified the planning, design and construction standards of charging facilities. Organize the revision of the Code for Operation and Management of Electric Vehicle Charging Stations (DB11/T 880-2020), which provides practical basis for the operation service, operation safety and guarantee requirements, occupation and disposal of oil vehicles, personnel management, complaint evaluation and improvement of electric vehicle charging stations. By issuing a number of local standards and norms, the standardization and standardization of the operation and maintenance of new energy vehicle charging and replacing power stations have been promoted, and a characteristic local standard system that leads the country and adapts to the capital has been formed.

　　4. Breakthrough in key technologies

　　The charging and replacing efficiency is greatly improved. The taxi-to-power station realizes rapid power exchange in 1.5 minutes, and the single-station service capacity reaches 600 vehicles/day. In the future, Science City will be the first public charging station in China with a single gun output of 360 kW, which can be charged for 5 minutes and run for 200 kilometers.

　　Some progress has been made in the integration technology of optical storage and charging. The light storage and charging integrated charging station of the Universiade Village in Haidian District of Jingneng Electric Power was completed and put into operation, realizing a new energy supply mode of three-dimensional parking+roof distributed photovoltaic+lithium battery energy storage+large charging station. Charging pile enterprises such as Putian New Energy and Zhichong Technology explore the construction of video charging integrated pile.

　　Carry out a number of key technical research. Enterprises such as Star Charging, China Merchants Sanyou, TELECOM, etc. respectively carry out research and development of charging robots and flexible charging technologies. State Grid Beijing Electric Power Company has accelerated the research and development of vehicle-network collaborative technology and accelerated the pilot demonstration of intelligent and orderly charging facilities in residential areas.

　　5. Interconnection has been continuously strengthened

　　Establish a "1+N" platform system. Relying on the public service management platform of charging facilities in Beijing, a service system of "one municipal platform +N enterprise platforms" was constructed, which promoted the integration of information and data among different platforms and enterprises, and formed a multi-level interconnection model of "government supervision and guidance+enterprise market operation".

　　Social services and industry management capabilities have been continuously enhanced. Relying on the public service management platform of charging facilities in Beijing, the functions of status inquiry, route navigation, online payment, charging quantity monitoring and safety supervision have been realized for more than 90% operating enterprises, large supermarkets, transportation hubs, P+R parking lots, park scenic spots, expressway service areas and other places in the city, providing information and data support for government decision-making, industry management and user service.

　　(2) Major issues during the 13th Five-Year Plan period

　　1. It is difficult to build charging facilities in residential areas.

　　Charging piles in residential areas have not been built according to local conditions. Some residential areas are restricted by hardware conditions such as parking, electricity, etc., or are not supported by the property, and other owners disagree, etc., and the construction of private self-use piles and community public piles is hindered. The key lies in the unclear relationship between rights and responsibilities of all parties concerned.

　　2. The utilization rate of charging facilities is low.

　　First, there are excessive advanced construction and unreasonable spatial layout of social public charging facilities in some areas, which leads to waste of social resources; Second, the electricity and parking fees of some social public charging piles are too high, and the comprehensive charging cost is much higher than other charging facilities; Third, the occupation phenomenon of non-rechargeable vehicles has not been completely eliminated, and the contradiction between parking and charging still needs to be further solved; Fourth, the internal piles of the unit and the public piles of the community are not open enough to the outside world, so it is difficult to make full use of them.

　　3. The service level of facilities needs to be improved.

　　The development mode of emphasizing construction over management in the industry leads to the need to improve the charging service level, and the increasingly diversified charging needs still need to be further met. In order to solve the basic charging demand and emergency power supply demand, and better meet the multi-dimensional demand characteristics of charging time, speed, location, price and matching, it is urgent to realize refined management and establish a new dynamic matching relationship between supply and demand.

　　4. The intelligent level of facilities needs to be improved.

　　The interconnection of charging and replacing infrastructure is mainly limited to public charging and replacing facilities, and the coverage of self-use and special charging and replacing facilities is insufficient, so the value of information and data is difficult to play. At the same time, as the core interface of transportation and energy, and the key anchor point between dynamic and static of electric vehicles, the charging and replacing infrastructure has not been interconnected with electric vehicles and parking lots, and the support for orderly utilization of facilities and full sharing of resources is insufficient.

Chapter II Development Situation

　　With the promulgation and implementation of the National New Energy Vehicle Industry Development Plan (2021-2035), the development of new energy vehicles will enter a new stage of accelerated development. As a new type of infrastructure, charging and replacing facilities will also enter an important window period of rapid technology iteration and industrial transformation and upgrading during the "14th Five-Year Plan" period, which needs to be closely combined with the strategic deployment of the national new energy automobile industry development, and be considered as a whole with the 14th Five-Year Plan of Beijing and the long-term goal in 2035. Generally speaking, the development of charging and replacing facilities during the 14th Five-Year Plan period faces three major situations: new mission, new expectation and new requirements.

　　(A) the urgent need to achieve high-quality development under the new mission

　　As one of the seven major areas of new infrastructure construction, charging and replacing facilities undertake the important mission of supporting the strategy of strengthening the country by automobiles, promoting the national new energy revolution and stimulating new kinetic energy for economic development. On the one hand, the Supreme Leader General Secretary pointed out that "developing new energy vehicles is the only way to become a powerful automobile country". As an important guarantee for the popularization of electric vehicles, charging and replacing facilities are also an organic part of China’s powerful automobile country. The "14th Five-Year Plan" of charging and replacing facilities should be planned around the high-quality development of charging and replacing facilities. On the other hand, the new energy revolution to promote the transformation from traditional fossil fuels to electrification will be carried out in depth, and the release of "New Energy Automobile Industry Development Plan (2021-2035)" has further strengthened China’s strategic determination to develop new energy vehicles; The 14th Five-Year Plan for Beijing’s National Economic and Social Development and the Outline of Long-term Goals for the Year 2035 also clearly stated that strategic emerging industries such as new energy smart cars will be vigorously developed. It is predicted that during the "14th Five-Year Plan" period, driven by the three major factors of economy, energy and environment, Beijing will accelerate the scale development of new energy vehicles, from the existing 400,000 vehicles to 2 million vehicles, and put forward corresponding requirements for the scale and quality of charging and replacing facilities. At the same time, under the new pattern of double circulation in the international and domestic markets, charging piles, as a new type of infrastructure, will be organically integrated with technologies such as 5G, big data, artificial intelligence and car networking.It will become a central node connecting automobile, energy and Internet industries, leading to the expansion of domestic demand and injecting new kinetic energy into China’s economic growth.

　　(B) Under the new expectations, it is urgent to improve the scale efficiency.

　　Charging and replacing facilities have experienced a large-scale expansion in the "13th Five-Year Plan" period, and the "14th Five-Year Plan" period will enter a new stage in which both scale and efficiency will be developed. Based on the people’s yearning for a better life, the society has also put forward new expectations for the automobile charging and replacing service. From the basic demand of "having piles to use" in the past, it has further upgraded to the quality demand of "using well", paying more attention to the charging experience in terms of charging speed and service quality. Therefore, during the "14th Five-Year Plan" period, charging and replacing facilities not only need to achieve scale growth, but also need to pay attention to the improvement of charging and replacing efficiency and service level, and strengthen the integration and coordinated development of electrification, networking and intelligent technology, so as to meet the needs of large-scale development of new energy vehicles, improve the public service guarantee ability of charging and replacing facilities, and meet people’s new expectations for higher efficiency and better experience of charging and replacing facilities.

　　(C) Under the new requirements, it is urgent to establish a digital intelligence ecology.

　　At present, China has entered a new development stage of vigorously developing the digital economy and promoting the modernization of governance system and governance capacity, which has brought important opportunities and higher requirements for the upgrading and transformation of the industry and the improvement of governance capacity. During the "14th Five-Year Plan" period, the charging and replacing facilities industry urgently needs to seize a new window of digital economy development. Based on the improvement of the interconnection level of charging and replacing facilities with big data, it will further accelerate the digital and intelligent upgrading of the industry, so as to achieve more detailed and intelligent decision support for overall planning of charging and replacing facilities, optimization of spatial layout, promotion of charging services, and efficient supervision of the industry. At the same time, it is also urgent to further deal with the relationship between the government, enterprises and consumers, build a coordinated development ecology with consumers as the core and industry-leading enterprises as the guide, covering cross-industry and cross-field integration and innovation such as charging and replacing facilities, new energy vehicles, energy supply and parking, and form a new pattern of social co-governance with multi-participation and win-win cooperation.

Topic: Global Blocking of Influenza A (H1N1)

Infectious disease expert Zhang Yanping

　　　 CCTV News: Zhang Yanping, an expert in infectious disease prevention and control in China Center for Disease Control and Prevention, had an online exchange with CCTV netizens on the prevention and control of new influenza A (H1N1). Zhang Yanping answered the question that netizens are concerned about whether H1N1 is a common disease or a difficult disease. He thinks that H1N1 is an infectious disease of respiratory tract, not a difficult disease, and it can be completely prevented and controlled according to the epidemic characteristics of influenza.

　　　 Zhang Yanping said that influenza A (H1N1) is a new infectious disease, which has just appeared, and we lack a basic understanding of its epidemic law and characteristics. It has not been found in the mainland, so the information we get is the basic information obtained through the exchange between the World Health Organization or some other institutions, not to say that it is a difficult disease, because it is an infectious disease of respiratory tract, and we have a basic understanding of common influenza and seasonal influenza, which we can completely prevent and control according to the epidemic characteristics of this disease.

　　　 Zhang Yanping said that the emerging disease can be called a new type of influenza A (H1N1), and the common influenza prevalent in China can be called seasonal influenza. First of all, the two diseases have different meanings and different genotypes. In addition, infectious diseases are the same, consistent, all patients and normal people mentioned just now, and the transmission route is the same, except that the virus of influenza A (H1N1) is reported to be mainly young and middle-aged. In addition, the epidemic performance is similar. Another important feature is that our seasonal flu has a corresponding vaccine, but this new type of flu has no vaccine at present.

　　　 Zhang Yanping told netizens that the Institute of Virus Prevention of China Center for Disease Control and Prevention, where he works, is an institution engaged in the prevention and control of infectious diseases, mainly focusing on the basic structure of these viruses and the whole development. For this time, our main task is to research and develop diagnostic reagents for influenza A (H1N1), which have been developed in this respect and may be diagnosed within 12 hours if necessary.

As the "king of fruit", people still have many questions about it, such as whether it is "fragrant" or "smelly"? Does durian shell have any other use value besides pricking people? Who should eat durian carefully … Don’t worry, let’s talk about durian in this article.

Is durian fragrant or smelly?

People have different opinions on the smell of durian, which is a combination of fragrance and odor. Some people say it is super "fragrant", while others say it smells like a gas tank. If durian is baked in the oven, it may be misunderstood by neighbors as "baking shit".

Why does durian smell so special?

In fact, the normal smell of fresh durian is very sweet, accompanied by onion flavor and elegant fruit fragrance, which is very delicious. However, if the picking time is too late and the durian is over-ripe on the tree, it will emit a sulfur smell. In addition, if durian is kept in a closed environment, it will also give off a special smell.

Some people have analyzed the flavor components of seven common durians, and found that there are 58 kinds of volatile substances in durian, so it has a strong flavor. Because of the existence of esters and sulfides, durian has its own unique and strong fragrance. Among them, sulfur compounds make durian produce a unique "onion-sulfur" smell, and different contents and proportions will also make people have different perceptions and evaluations. Sulfide components are the highest in Jinfeng durian, so its smell is the most special and strong; The existence of esters makes durian have fruity aroma and pleasant smell, which is the highest among the golden pillow durian, but it will also be affected by factors such as heredity, environment (temperature, rainfall, altitude), cultivation and harvesting technology.

How about durian nutrition?

Durian is delicious, but its nutrition is really good.

-Vitamins: Durian has better vitamin content than many common fruits, such as vitamin B, vitamin E, nicotinic acid, etc.

-Minerals: Durian has good potassium and magnesium content, especially the potassium content is as high as 261 mg /100 g, which is higher than that of bananas that can supplement potassium in everyone’s mouth. Eating 100 g can meet 13% of the daily potassium demand of the general population, which is also very helpful for controlling blood pressure.

-protein: Although the quality of protein in fruit is not as good as that of meat, eggs and milk beans, in terms of content, the protein content of durian is considered as the best in fruit, which can provide 2.6 grams of protein per 100 grams, 6.5 times that of apples.

-Dietary fiber: According to the nutrition database of USDA, the total dietary fiber content of durian is 3.8g/100g, which is 1.6 times that of apple.

However, although durian is rich in nutrition, its calories can not be underestimated. The calorie per 100 grams is as high as 150 kilocalories, which is equivalent to a small bowl of rice.

How to use durian shell and durian core?

Although durian is soft inside, it is covered with armor and thorns. Most people throw away durian shells and durian cores when they eat durian, thinking that it is useless to keep these two goods.

▲ Figure: durian shell (left) and durian core (right)

In fact, they can really use it. Both the white pulp endothelium of durian shell and durian stone can be used to make soup, which can increase the flavor of soup. Durian stone can also be cooked and eaten alone. After cooking, peel off the outside and there is a small nut inside, which tastes a bit like chestnut and is quite delicious.

▲ Figure: Small nuts in durian core

In addition, durian shell and durian stone also have some nutritional value. Animal experiments show that the extract of white pulp endothelium from durian shell has certain anti-inflammatory effect; Durian stone contains vitamins, minerals and other nutrients.

How to buy a good durian?

-Look at the crack: durian will crack when it matures. Try to choose a smaller crack, which will increase the risk of pollution.

-Look at the color: With the increase of durian maturity, the durian shell will gradually turn yellow, which may be caused by the increase of β -carotene content. Therefore, choosing durian with a yellow shell means that it is relatively more mature. If the color is blue, it means that the maturity is not enough, and the taste may be worse.

-Smell: Choose something sweet and fruity, and don’t choose something with obvious odor, which may be too mature or deteriorated.

-Touching the fruit thorns: With the increase of durian maturity, the fruit thorns will gradually soften and the thorns will turn brown. If the durian thorns are blue or hard, it is not mature enough.

▲ Figure: The tip of the fruit thorn turns brown.

-Tap to listen to the sound: When the fruit reaches a certain maturity, there will be a gap between the pulp and the shell. When something is tapped on the fruit (such as the back of a knife), it will make a hollow sound.

-Variety selection: Durian with golden pillow is the largest, with more pulp, smaller seeds and high edible rate, but with thick peel and high organic acid content; Maoshanwang durian has large fruit, more pulp, thicker peel and higher soluble solids content.

How to store the durian I bought?

If durian is left too long, it will make people smell bad more easily. This is because durian is a climacteric fruit, which means that during the period from the stop of growth to the beginning of aging, the respiratory rate will suddenly increase and there will be a peak. This process will release ethylene, the respiration will rise rapidly, and the fruit will be more mature.

It was found that durian’s respiratory jump was very active at 24℃, 27℃, 30℃ and 33℃. Too mature durian is easy to rot and stink.

Therefore, in order to inhibit the degree of respiratory jump of durian during storage, it must be placed in a low temperature environment. However, because it belongs to tropical fruit, chilling injury will occur if the storage temperature is too low, especially when it is stored with skin. For example, durian with golden pillow will suffer chilling injury when it is stored at 13℃.

Therefore, if the durian is shelled, it is recommended to store it at about 15℃, and it can be stored for about 3 weeks at the longest. Because durian meat is less prone to chilling injury than durian shells, durian meat can also be peeled off separately, wrapped with plastic wrap and stored in the refrigerator. Depending on the maturity, it can be stored for up to one month, but the flavor may deteriorate if it is stored for too long, and it is best not to exceed half a month.

In addition, durian pulp can also be frozen and preserved, even if it is preserved for more than 3 months, the flavor is still good, and a durian ice cream can be harvested.

Who should eat durian carefully?

Although durian has a unique flavor and a smooth and sweet taste, not everyone can eat it. There are four types of people who must eat less or not eat durian.

-Diabetic patients: Although its GI value (glycemic index) is not very high, only 49, which is a food with low GI, its carbohydrate content is as high as 28.3 g /100 g, which contains sucrose, glucose, maltose and fructose. After eating 100 g of durian, the GL (glycemic load) is more than 10, and the range of blood sugar increase is quite obvious.

Therefore, if you have high blood sugar, try not to eat it.

-Obese people: Durian is among the best among fruits in terms of calories. Eating as much as a fist is equivalent to a small bowl of rice and nearly three times as much as apples. If you want to control your weight or lose weight, you must keep your mouth shut and eat less durian.

▲ Figure: One piece of durian meat is about 90 grams.

-Nephropathy patients: Durian is a high-potassium fruit. Nephropathy patients with hyperkalemia should try to eat less or not.

-People allergic to durian: Some people may be allergic to durian, so don’t eat it.

　　August 23 is the last day of the last day, and the dog days of 40 days are coming to an end. As the saying goes, "the heat is in the dog days", which is often the hottest period in a year. After the dog days, the summer heat is weakening. Although some parts of southern China are still in hot weather, most areas are about to withdraw from the "high temperature circle".

　　Is the high temperature abnormal this summer?

　　High temperature is a common weather phenomenon in summer. It can be defined as high temperature weather when the highest temperature on that day exceeds 35℃, and high temperature for several days in a row constitutes a high temperature heat wave.

　　It can be seen from the occurrence time of the highest temperature in various places since June this year that the high temperature weather in China has obvious characteristics of regional changes in stages. The main position of high temperature in June is located in North China, Huanghuai and other places. Under the control of warm and high pressure in the mainland, the weather in this area is sunny and sunny in partly cloudy, with strong solar radiation and strong near-surface heating, which is easy to form continuous high temperature weather; In July, with the extension of subtropical high to the west, the plum rain in the south ended, the rain belt moved northward, the rainfall in the north gradually increased, and the high temperature eased. At the same time, the subtropical high stayed in the south for a long time, and the high temperatures in Jiangnan, northern South China, eastern Jianghan and Jianghuai developed and continued.

　　Since July 3rd, large-scale high-temperature weather has occurred in Jianghuai, Jianghan, Jiangnan, South China, Sichuan and Chongqing. The high-temperature duration in Zhejiang, Fujian, Jiangxi, Hunan, southern Jiangsu and Anhui is long, and the number of high-temperature days in some areas has reached more than 30 days, and in some areas of Zhejiang and northeastern Jiangxi, it has exceeded 40 days. Among them, the high temperature in Zhejiang is extremely extreme, and 10 national observation stations have exceeded the historical extreme value of the highest temperature. The highest temperature in more than 60% of the stations has reached above 40 C, and the highest temperatures in Yiwu, Lishui and Jiande have reached 42.8 C. Hangzhou ranks first among municipalities and provincial capitals in terms of high temperature days and continuous high temperature days. The temperature of 41.9℃ on August 3rd became the highest among municipalities and provincial capitals this year.

　　The weather is getting hotter and hotter, which is also reflected in the early and more high-temperature warnings.

　　According to the "Measures for the Issuance of Meteorological Disaster Early Warning of the Central Meteorological Observatory", the high temperature early warning is divided into three levels, from weak to strong, namely yellow early warning, orange early warning and red early warning. So far this year, the Central Meteorological Observatory has issued 61 yellow warnings and 34 orange warnings for high temperature weather. From June 9 to 15, the first regional high-temperature weather process occurred in China this year, four days earlier than normal. The first high-temperature orange warning was released on June 10, 12 days earlier than the first high-temperature orange warning in 2023.

　　With the climate warming, in recent years, the national average temperature has hit record highs. According to the statistics of the Central Meteorological Observatory, the national average temperature from June 1 to August 22 this year was 22.2℃, which was significantly higher than the normal period (21.3℃), ranking second only to 2022 (22.4℃) since 1961.

　　What needs special reminder is that at present, the high temperature in some areas such as Chongqing and the middle and lower reaches of the Yangtze River continues. Up to now, Chongqing is still in the highest level of high temperature red warning. According to the forecast of the Central Meteorological Observatory, from August 24th to 27th, the hot weather will continue in Sichuan, Chongqing, southwestern Shaanxi, Guanzhong, Hubei, Hunan, Jiangxi, Anhui and other places, with a daily maximum temperature of 35.℃To 37℃, Sichuan, Chongqing and other local areas can reach 40℃To 42℃; After 28th, the high temperature weather in the above areas has eased, but the high temperature in Sichuan and Chongqing will last until the beginning of September. Please ask the public in the above areas to take measures to prevent heatstroke and reduce outdoor activities during high temperature periods as much as possible; High temperature weather will lead to an increase in electricity consumption. Please pay attention to the safety of electricity consumption and turn off the power supply of all kinds of electrical equipment before going out to prevent fire accidents caused by short circuit or fever of electrical appliances.

　　High temperature sweeps across the northern hemisphere

　　High temperature weather not only appears in China, but also affects most parts of the northern hemisphere, and it also comes earlier and stronger. At present, hot weather is sweeping across many European countries, with the highest temperature in Italy, Germany, Serbia and other countries exceeding 40℃.

　　In March this year, the World Meteorological Organization (WMO) released the Report on Global Climate in 2023. According to the report, 2023 became the hottest year since meteorological records began, and the average temperature near the surface was 1.45℃ higher than the pre-industrial level. The concentrations of three main greenhouse gases, carbon dioxide, methane and nitrous oxide, are still rising. The concentration of carbon dioxide is 50% higher than that before industrialization, and the world is in an unprecedented warming process.

　　Under the climate background of global warming, the average temperature rises, high temperature weather tends to be frequent, and extreme high temperature events increase or become the new normal. The meteorological department will strengthen the monitoring and forecasting of high-temperature weather, formulate emergency plans to deal with extreme weather, release early warning information in time, remind the public to take precautions, strengthen the publicity of popular science, make the public better understand the impact of climate change on life, take the initiative to take self-protection measures, and enhance the adaptability of the whole society to climate change.

　　Institution: The potential market space for garbage sorting is nearly 100 billion.

　　Source: TF Securities Research Report

　　TF Securities believes that garbage sorting is accelerated, and the overall space is nearly 100 billion, which directly benefits the sanitation industry. According to the standards of 20 yuan/month for urban residents and 10 yuan/month for county residents, the overall market space for garbage sorting is over 80 billion. According to the requirements of the Ministry of Housing and Urban-Rural Development, 46 cities across the country will complete garbage sorting by 2020; By 2025, domestic waste sorting and treatment systems will be basically established in cities at prefecture level and above. There are about 100 million households in 46 cities. According to the calculation of 20 yuan/household/month, the market space to be released before 2020 is about 24.2 billion.

　　In addition, while accelerating the marketization of sanitation, garbage sorting also integrates more work content into sanitation orders, and the trend of large-scale industry orders is strengthened, providing a new growth pole for the traditional sanitation industry.

　　Soochow securities predicted that in 2025, the environmental sanitation service market in China will be 468.5 billion yuan, and the space of environmental sanitation marketization will increase by 134%: the advantages of standardization, mechanization and management will promote the concentration of shares, and standardization will drive the increase of large contracts.

　　Cuba’s citizens are well known for free medical care, and the medical institutions in this Caribbean island country have also developed some new special medicine treatments, which have enabled many patients to find here from Wan Li, not far from all over the world. Treating intractable diseases has become another feature of Cuban medical care.

　　[Special medicine for auxiliary treatment of lung cancer]

　　CIMAvax-EGF, an adjuvant drug for lung cancer, is a unique drug developed by Cuban Center for Molecular Immunology and registered in 2008. It can strengthen the human immune system and give chemotherapy time to respond, thus improving the treatment effect of lung cancer.

　　Eduardo Osito, deputy director of the Cuban Center for Molecular Immunology, said that the research and development of CIMAvax-EGF exhausted the efforts of the first generation of scientists in the center. It is mainly composed of epidermal growth factor (EGF) and another protein P64K. Cuban medical personnel realize that EGF molecules play a very important role in the process of tumor evolution. "CIMAvax-EGF does not directly kill cells, but it can make them hungry by preventing EGF from attaching to the cell’s self-sensor," Osito said. "This correlation is the key to prevent cell growth and proliferation."

　　Unlike many other cancer therapies that have serious side effects, patients who use CIMAvax-EGF have a good tolerance to drugs. According to Osito, 30% of patients treated with this drug have significantly improved their quality of life.

　　In view of the current treatment situation of the drug, scientists believe that it is likely to have potential curative effect on cancer cells such as head and neck cancer and colon cancer that depend on EGF growth.

　　Cuba’s national medical system used this special medicine for the first time in 2012, and thousands of patients have benefited so far. At present, four countries use this medicine.

　　In January this year, Roseveare Park Cancer Institute cooperated with Cuba, and the drug began clinical trials in the United States, and it is planned to be approved by the US Food and Drug Administration (FDA) for use in the American market.

　　[Gold Award-winning Diabetes Drugs]

　　Heberprot-P is a new special medicine introduced by Cuba in 2006 for treating diabetic foot ulcers. Its appearance has saved a large number of patients from amputation.

　　The medicine is a unique product developed by Jorge Bellanga, a Cuban scientist, and the team of the Center for Genetic Engineering and Biotechnology. It contains the active pharmaceutical ingredient of epidermal growth factor (EGF) and works by direct infiltration or injection into the injured area.

　　Dr. Manuel Raisez, a member of the research team of the Center, said: "With each injection, amino acids and protein compounds can differentiate cells, and healthy and energetic tissues begin to be injected into the ulcer site. After an average of about three months, the wound is completely healed."

　　In 2007, Cuba built a clinic specializing in treating diabetic foot ulcers, but the demand far exceeded expectations. The Cuban Ministry of Health decided to start a national treatment project, and there are 458 specialized clinics at present.

　　Laissez said: "This makes our current diabetes amputation rate in the world the lowest, only 3.8%." He said that there are nearly 1 million diabetic patients in Cuba, and there are about 35,000 cases of diabetic foot ulcers every year. In 2016, only 480 cases were actually amputated.

　　Laissez and scientists from the Center have given lectures on the drug and its use in more than 20 countries, including Russia, Kuwait, Algeria, Argentina, Ecuador and Venezuela. At present, Heberprot-P has been registered in 23 countries and has been effectively used in 10 countries.

　　The implementation of this project in Cuba has been internationally recognized. It was launched to the international market 10 years ago and won the gold medal of intellectual property rights awarded by the World Health Organization.

　　[biopharmaceuticals become Cuban characteristics]

　　The research and development of new special drugs reflects the achievements of Cuba in developing medical biotechnology industry for many years. Dengue fever in the early 1980s prompted Cuba to develop Interferon；, which can stop potential viruses. In 1990, the hepatitis B recombination vaccines was developed, which almost eliminated hepatitis B in Cuba. A single dose vaccine called Heberpenta can protect against diphtheria, tetanus, whooping cough, hepatitis B and influenza B.

　　Other famous drugs developed in Cuba include Pentavalente for treating virus infection, Estreptokinasa for treating heart disease, PPG for treating cholesterol disease, Nimotuzumab for treating head and neck cancer, Eritropoyetina Human Recombinants for chronic anemia and granulocyte colony stimulating factor (g-csf) in leukemia patients.

　　Cuba has also developed many botanical drugs. The Natural Medicine Center under the National Scientific Research Center of Cuba uses palm tree fruit extract to make drugs for treating benign prostatic hypertrophy; Extracted from local wild plants in Cuba and made into drugs for autoimmune diseases; Abexol；, an antioxidant drug with anti-aging effect made from purified beeswax extract; Calcium supplement Suplecal；; Prevenox； for treating osteoporosis; PPG for controlling cholesterol level made from sugarcane extract, etc.

　　[Special medicine breeds medical tourism]

　　In the 1990s, in order to reverse the huge impact on Cuba’s economy after the disintegration of the Soviet Union, the Cuban government made great efforts to develop the tourism industry in order to obtain the foreign exchange badly needed by the country. With Cuba’s opening up to foreign tourists, tourists found that Cuba had a high success rate in treating many diseases, some of which were even better than their own countries, and medical tourism came into being.

　　Established in 1987, Cuban Medical Service Agency (SMC) mainly provides medical services for foreigners. Dr. Ianna Alvarez, director of the agency’s sales department, told reporters that SMC has signed agreements or established strategic partnerships with about 41 countries, that is to say, SMC has cooperative relations with some institutions, medical insurance companies, service export units or clinics that transport patients to Cuba for treatment.

　　Patients who come to Cuba for treatment through SMC come from all over the world, including Canada, Europe, the United States, Central America and South America. The needs of patients in Cuba are different. Many Canadian patients come to Cuba for cosmetic or plastic surgery, such as lumbar replacement, hip replacement, knee prosthesis and other treatments. Such operations need to wait for a long time in many countries; Central and South American patients come to receive nervous system treatment; Europeans mainly come to perform various eye operations and treat psoriasis, lung cancer or foot ulcers with drugs developed by Cuba …

　　Because patients come to Cuba for treatment through different channels, SMC does not have complete data, but one thing is certain, that is, the demand of international patients is increasing every year, so Cuban health authorities begin to open new foreign-related institutions and facilities in large hospitals.

　　According to Alvarez, China and Cuba have established cooperation in medical services. She said: "Because China and Cuba are far apart, it is difficult to launch a comprehensive plan for Chinese to be treated in Cuba. However, once patients have accurate information about treatment, I believe they will have high satisfaction. "

　　Alvarez said that Cuban medical services will send professionals to China to promote health care projects in the future, so that more Chinese can understand and benefit from Cuban medical services. (Ma Guihua) (special feature of Xinhua News Agency)

　　In July, Gamma Data released the "2019 China Game Industry Semi-annual Report" — — In the first half of the year, the growth rate of China Mobile’s e-sports revenue was far ahead of that of client-side e-sports games, accounting for more than 60%.

　　Earlier, the Leisure Game Market Opportunity Research Report of 2018-2019, also from gamma data, pointed out that mobile leisure game users accounted for 66.4% of the total mobile game users in the past year, but leisure games only accounted for 6.6% of the mobile game market & hellip; …

　　Thanks to the demographic dividend of China and the rapid development of mobile Internet, mobile e-sports has gradually become the main force in the field of e-sports, but mobile leisure games are still a low-lying area with huge room for growth, which seems to mean that "mobile e-sports+leisure" will become an opportunity in the development tide of e-sports and games in China.

　　In the e-sports market, female users surged.

　　In the 2019 Tatan Elite Challenge, which just ended in Qingdao, 12 teams fought for two days, attracting thousands of live audiences and over one million online audiences. It seems that the e-sports event created by a light casual game also has strong box office and market appeal.

　　In fact, the Tatan Cup has been born for four years, and the popularity of "Ball-Ball Battle" is behind it.

　　As a casual game produced by Giant Network, official data show that there are more than 500 million users, 10 million daily activities and 150 million monthly activities, and the gender ratio of players is close to 4 to 6 (35% women and 65% men); In terms of age, 40.08% of the players aged 18 to 24, and 33.07% of the users aged 13 to 17 & hellip; …

　　The rise of "Ball Fight" has indeed caught up with the fast lane of China mobile e-sports development — — It was launched in mid-2015, which is earlier than many popular mobile games, but the precise positioning is probably more worthy of attention.

　　In the e-sports game market, especially on the mobile side, the scale of female users has surged.

　　Public data shows that from 2013 to 2018, the number of female players has increased from less than 80 million to 290 million.In the past, there were high barriers to heavy games, which made light games that focused on "leisure" just needed by the market. Its "popularization", such as relatively simple rules and operation, was not only more suitable for covering young people of all ages, but also met the needs of the rapidly growing group of female players.

　　In fact, not only female players, but also professional players in Tatan Classic, which is a difficult scene to see in other e-sports events.

　　Leisure+animation, the future industrial direction

　　Of course, there is still a long way to go from a popular game to a traditional e-sports event.

　　On the one hand, it benefits from the high stickiness of mobile e-sports users. According to the survey, the proportion of mobile e-sports users playing games every day is as high as 43.1%, and the proportion of playing games every week is also 25.3%, among which the proportion who are willing to watch events online is as high as 67.2%.

　　In addition, industry insiders also analyzed that while the competition of heavy game e-sports is intensifying, leisure e-sports built around light games is expected to become a "single product" in the market. Since 2016, Giant Network has successively launched a series of subdivided events such as BPL Professional League, Tatan Cup Elite Challenge, CEST Campus Challenge and BUC City Challenge, and deeply cultivated leisure e-sports.

　　It is worth mentioning that while maintaining the attributes of the game, leisure e-sports emphasizes the social functions in e-sports games.

　　According to statistics, "Ball Battle" creates a community online through team battles, seasons, leaderboards and other settings. On average, each player has 15+ friends, and the platform generates more than 12 million private messages every day, with a cumulative upload of more than 100 million selfies.

　　In terms of offline events, the Tatan Cup is closer to the carnival, with diverse scenes such as band performances, players meeting, audience interaction with the event presented together.

　　With the increasing social needs of young people, mobile e-sports has become a social product to some extent. According to the 2018 China Leisure Mobile Game Industry Report released by iResearch, 82% of leisure mobile game users said that they need to meet social needs in the game.

　　Producer Wu Meng has also said that social attributes will help game products to extend their life cycle. In fact, for leisure e-sports with weak antagonism, socialization is not only empowerment, but also its lifeline.

　　At present, giant network’s e-sports are actively seeking cross-border and circle-breaking. The previously launched "Journey" series has joined hands with the classic animation "Huluwa" to implant Huluwa elements in e-sports games. At present, the serial comics "Xingyun Brigade" and the virtual idol "Tatan" related to "Ball Fight" are also officially launched … …

　　Judging from the industry and market forecast, leisure, animation and massively multiplayer online e-sports and games still have considerable potential in the future.

In October, 2021, the sculpture of "Big Guitar" beside Binjiang Leisure Square in Ji ‘an, Jilin. The pictures in this article are all Matt diagrams.

I will leave Dandong for Ji ‘an along the Puyi Palace in Dandong.

On August 9, 1945, the Soviet army entered the northeast, and Puyi went to Ji ‘an from Xinjing (now Changchun), the capital of the puppet Manchukuo, to prepare to flee to Japan through Korea, and he would spend 10 days in his life. There have been many such days before, and there will be more later.

On August 13th, Puyi stopped at Dalizigou Mining Institute of Dongbiandao Development Co., Ltd. near Linjiang in the north of Ji ‘an. On the 15th, Japan surrendered, and on the evening of 17th, in the miners’ canteen, Puyi announced his abdication for the third and last time in his life, and the Kantian dynasty of Manchukuo ended. On the 19th, Puyi arrived in Fengtian (present-day Shenyang) through Tonghua, was arrested by the Soviet troops who occupied the airport by air at Dongta Airport, and then was escorted to Chita (present-day capital of post-Baikal Territory of Russian Federation).

Five years later, when the Korean War broke out, the advance team of volunteers first entered North Korea from Ji ‘an for reconnaissance. Ji ‘an county was established in 1902, taking the meaning of "Your Majesty acceded to the throne, saved the world and set up an China" in Biography of Historical Records and Sima Xiangru. In 1965, in order to take care of North China’s national sentiment, the South Korean government renamed Ji ‘an Ji ‘an. In 1985, Ji ‘an was under the jurisdiction of Tonghua City, and in 1988, Ji ‘an established a city (county-level city).

coach

There is no direct train from Dandong to Ji ‘an, only a 4320 train from Dandong to Tonghua, which leaves the next day. Although the scenery along the train is wonderful, it doesn’t match my travel time, so I choose to take a long-distance bus instead.

In the era when high-speed rail is becoming more and more convenient, long-distance buses are becoming rare in first-and second-tier cities, but in small cities and rural areas, they are more convenient and flexible modes of transportation. Now high-speed railway station is far away from the urban area, and most of the long-distance bus stops are still in the city center. When passing through the mountainous areas of villages, long-distance buses will stop at any time according to the needs of passengers, which is an irreplaceable function of trains.

I like listening to drivers and bus captains chatting on long-distance buses. They will pay attention to the recent increase in vegetable prices, the situation in the Taiwan Strait, the poor economic development and employment situation in Northeast China, and finally the topic will always fall on their bus operation.

During my trip, there were only single-digit passengers at the starting station, and villagers occasionally hitchhiked during the four or five-hour journey, and the fare was only a few dollars. I understand that drivers have to carry a lot of goods to earn a little hard work. Apart from a small amount of personal express delivery, many of those goods are ingredients and engineering items in village shops along the way. As these buses are fixed trains, pulling goods is the main income of those drivers.

Our bus passed Hunjiangkou Bridge halfway, which is the confluence of China-Korea border and Liaoning-Jilin border. Hunjiang is the ancestral home of the Jurchen people in Jianzhou, once called Tongjiajiang. Tong Jia is a Manchu surname. The Tong family was originally a prominent family of Han people in Liaodong, and they had a good relationship with Jurchen. Emperor Kangxi’s mother and imperial concubine were both from Tong Jiashi. He ordered Tong Jiashi to be changed from the Eight Banners of Han Dynasty to the highest yellow flag.

"Big Guitar" Sculpture

In this city, which is famous for its world cultural heritage on the border between China and North Korea, I have to look for a very new landmark first: the "big guitar" sculpture.

In the movie Sewing Machine Band, the cement guitar sculpture in a fictional rock park exists as a symbol of idealism. This movie, with the theme of rock band, takes place in Ji ‘an, and the local people also know the shooting scene. But maybe it’s just because the director himself is from Ji ‘an. The rock capital in the movie has nothing to do with Ji ‘an in reality. The driver was also confused when I asked if there was a local band performance venue and asked if I was a KTV or a bar resident.

I walked to the riverside leisure square by the river, and a huge guitar sculpture was set up next to the square, but not the one in the movie. The guitar sculpture in the film was demolished in the plot. Later, the Ji ‘an municipal government suddenly realized the influence of this film and felt that it might attract young artists to travel here, so it really built a "big guitar" sculpture.

In October, 2021, next to Binjiang Leisure Plaza in Ji ‘an, Jilin, the landmark building "Big Guitar" sculpture in the night.

The "big guitar" in the movie is made of concrete, and its appearance and tone are relatively calm. Now, in order to cooperate with the light show, it has been changed into a pure white and more modern shape, and its position has also changed. At night, there is no rock music performance in Binjiang Leisure Square, only a square dance that is uniform and not lost to Arirang on the other side.

In October, 2021, Ji ‘an, Jilin, was the riverside leisure square at night, and in the darkness in the distance was North Korea on the other side of the Yalu River.

In 2004, 43 sites (42 in Ji ‘an) of Koguryo’s royal city, tombs and noble tombs were listed in the World Cultural Heritage List. The city of Ji ‘an is completely attached to the Koguryo site. The former Koguryo Capital Domestic City happened to be in the core block of Ji ‘an City.

With Goguryeo Ruins Park as the center, the ruins of domestic cities are all over the city, surrounded by the ruins of gates, city walls, turrets and drainage culverts. The city wall made of rectangular stones is surrounded by wooden fences, and there are many old people exercising beside the drainage culverts of the west city wall. Next to the Wenmen of Dongcheng wall is Ji ‘an Morning Market, but the Goguryeo Ruins Park in the center of the city itself has no ruins, and it is purely a fitness and leisure park.

Walking along the city wall is like walking in a big park, because many sites are in residential areas. It is also a rare experience to touch the world cultural heritage as soon as you get downstairs.

In October, 2021, Ji ‘an, Jilin, was the site of Koguryo National City in the urban area.

Wandu Mountain City Fortress

The next morning, I arrived in Marudo Mountain City. At that time, it was cloudy and slightly cold, which was very suitable for climbing mountains. The taxi driver told me that I didn’t have to go into the mountains, so I just had a look outside by car. That was probably the aesthetic fatigue of their locals.

In the eyes of people who don’t understand, there are no large-scale architectural remains in this mountain. It seems that there is nothing to see, just a pile of stones and graves. But people who know it will know that Marudo Mountain City is a fortress of repeated tug-of-war between Koguryo and the Central Plains regime in Liaodong and the northern part of the Korean Peninsula, from the Han Dynasty to the Tang Dynasty.

October, 2021, Ji ‘an, Jilin, Koguryo Marubu Mountain City Site.　

After the Han Empire conquered Weiman Korea, it set up four counties in Liaodong, and named the place where the native nationalities in Northeast China lived as Koguryo County, which was under the jurisdiction of Xuantu County. In 37 BC, Go Jumong, the prince of Fuyu (an ancient nation who lived in the northeast of China from the Han Dynasty to the Tang Dynasty), was pushed away and established an independent country, Koguryo, in Zubenchuan, which is now Wunv Mountain in Huanren, Liaoning Province, which is referred to as Juli in Chinese classics. In AD 3, Koguryo moved the capital to the domestic city, which is now Ji ‘an, and built Wei Na Yan City as the acropolis on the mountain, echoing the domestic city. This echo of two cities on the mountain and below is the characteristic of Koguryo city, and the ancient cities on the Korean peninsula also have this design, which is a defense habit in war-prone areas.

In 197 AD, Gongsun Du, the Eastern Han Dynasty Liaodong satrap, attacked Goguryeo, and the present Marubu Mountain City was expanded and renamed by the 10th King "Mountain King" to resist Gongsun Du’s invasion. Goguryeo joined forces with the Cao Wei regime to fight against the Gongsun family, but soon after, the two sides turned against each other. From 244 to 245 AD, Wu Qiujian, an assassin from Youzhou of the Cao Wei regime, went on an expedition to Goguryeo and destroyed Marubu Mountain City, but Goguryeo soon rebuilt the city.

In 311 AD, during the reign of Meichuan King, Goguryeo was in a strong position in the northern part of the Korean Peninsula and began to counterattack. By the time of Guangkai King, it occupied all the land east of Liaohe River. However, at this time, China entered the great division period from Wuhu Sixteen Countries to the Southern and Northern Dynasties, and new opponents appeared one after another. The first confrontation with Goguryeo was the Qianyan regime. In 342 AD, Murong Mu, the founding monarch of Qianyan, attacked Goguryeo and destroyed the Marubu Mountain City again. Fortunately, at this time, there are only 30 years left before the most ambitious monarch in Koguryo’s history succeeded to the throne, and Koguryo is about to enter its heyday.

I got off and walked to the foot of Marudo Mountain. For a long time, it was forgotten in the wilderness because of the blockade outside the customs. Until 1906, when the road was built, the "Buqiujian Ji Gong Monument" was discovered. The inscription recorded the historical facts of the expedition to Koguryo mentioned above.

The mountains in the east, west and north of Marudo Mountain City are steep, with broad and gentle flat land in the middle and low terrain in the south. The city wall is built on the cliff in the south and surrounded by a moat. I am the only one in the whole Marudo Mountain. The layout in the mountain city is very simple, and the number of buildings is not much. The palace is the center, but only the cornerstone remains, as well as the watchtower and the garrison station.

October, 2021, Ji ‘an, Jilin, Koguryo Marubu Mountain City Site.　

There is a small lotus pond in the mountain city. There is a story about this lotus pond. In 28 AD, the Han Empire attacked Goguryeo, and the third monarch of Goguryeo, King Dawu, stuck to Marubu Mountain City. The Han army hoped to make Goguryeo surrender by siege. King Dawu caught a carp from the lotus pond and wrapped it with aquatic plants and sent it to the military camp of the Han army. When the Han army saw the carp and aquatic plants, they thought that there was enough water and food in the city to be besieged, so they withdrew.

Walking out of the mountain city, I came to the Koguryo cemetery at the foot of the mountain. I was too relaxed and happy along the way. The mountains in the distance fluctuated and birds echoed, and there were tombs nearby.

In October, 2021, the Koguryo aristocratic tombs at the foot of Marudo Mountain in Ji ‘an, Jilin Province.　

Koguryo advocates thick burial, and the exterior of the mausoleum is piled into a cone with multiple layers of stones. In this cemetery, we can see the characteristics of Koguryo’s tombs in different historical periods: some of them are lined with strips of stones at the bottom and covered with gravel; Some of them are built directly with large stone strips; There is another kind, which is closer to Han tombs, that is, mounds.

Koguryo people believe in natural polytheism, so the murals in the tombs here mostly depict the gods of the sun and the moon. Later, Buddhism was introduced to Koguryo from the Central Plains, and Koguryo began to believe in Buddhism. Koguryo civilization influenced the whole Northeast Asia in later generations. It can be said that this mountain is the land of Longxing in Northeast Asia.

Haotai tomb and Changshou tomb

After leaving Marudo Mountain City, I went to two tombs in the urban area: Haotai Mausoleum and Changshou Mausoleum, which were developed as the core scenic spots of Koguryo Ruins in Ji ‘an. King Haotai and King Changshou were father and son. During their reign (AD 391-491), Koguryo’s national strength reached its peak.

Haotai Mausoleum is a small scenic spot, mainly visiting tombs and tombstones. When I entered the cemetery, the first thing I saw was the famous monument of King Hao Tai. The huge monument was covered by a glass wall room, but I could walk in and visit it. The full name of this monument is "The Monument to King Haotaiwang, whose land is wide open in Guogang", which records Koguryo’s founding history, King Haotaiwang’s life achievements and information about the laws and regulations of grave keepers, the most important part of which is the story of King Haotaiwang’s conquering everywhere during his reign.

In October, 2021, Ji ‘an, Jilin, the monument of King Haotai in Koguryo remains scenic spot.

Haotai Aric Tan De was born in an era of crisis in Koguryo. Shortly after his birth, his father, Koyilian, was killed in a battle with Baekje. Baekje was ambitious for the control of the Korean Peninsula. At this time, the Houyan Murong family who occupied Liaodong often threatened Koguryo. King Haotai, who succeeded at the age of 17, faced the risk of being attacked by both the north and the south.

King Haotai showed his superb strategic mind at this time. He pretended to surrender to Hou Yan to the north to avoid confrontation, and first solved the threat of Baekje in the south. King Haotai led the army to defeat Baekje many times and established his absolute superiority on the Korean Peninsula. At this time, Houyan was facing the attack of the newly rising Northern Wei Dynasty, and Goguryeo no longer obeyed Houyan. After defeating Houyan’s attack in a row, Wang Faqi fought back and occupied Liaodong. During this period, Japan began to intervene in the situation on the Korean Peninsula, and Baekje tried to form an alliance with Japan. King Haotai attacked Baekje again and drove Japanese forces out of the Korean Peninsula.

Go along the path after the monument to the Great King, and you will come to the foot of the tomb. Haotai Mausoleum looks not high from the flat ground, but it has a large area, surrounded by gentle slopes, and the terrain is open, and there is a step that can walk to the door of the tomb. Different from the tomb in Han Dynasty, the tomb is set underground, with a sealed mound above it, and the tomb of Haotai Mausoleum is at the top of the tomb.

In October, 2021, Ji ‘an, Jilin, the Haotai Mausoleum in Koguryo Ruins Scenic Area.　　

I walked up the steps to the tomb and came to the door of the tomb. The opened tomb was built with large strips of stone, but the top and the outside of the tomb were surrounded by broken stones, and some stones were scattered at random, which was different from the tomb of his son Changshou Wang that I saw behind me. Perhaps it took too much energy to dig stone tablets, so the tomb itself was a bit ordinary.

Walking down from Haotai Tomb, I went to Changshou Tomb. Perhaps in order to build a tourist city, although Ji ‘an has a small urban area, it has introduced a developed shared electric car. Except Marudo Mountain, other scenic spots can be visited by electric car, which is very convenient.

Changshou Mausoleum is located 1.5 kilometers east of Haotai Mausoleum, which is called "Oriental Pyramid" in tourism propaganda. Tourism propaganda is always misleading. When a mausoleum is called the Oriental Pyramid, people will inevitably compare it with the pyramids in Egypt. In fact, the mausoleum is not very tall, but it looks like a pyramid.

In October, 2021, Ji ‘an, Jilin, was the tomb of Changshou in Koguryo Ruins Scenic Area.　

Walking in front of the tomb of Changshou, it is not difficult to find that the construction technology of this tomb is obviously more advanced and advanced than that of Haotai Tomb. The tomb of Changshou Mausoleum is built into a square cone by huge stone strips layer by layer, and there are seven steps step by step. A huge tombstone is placed around the tomb and pressed on the outer wall to offset the outward force caused by the weight of the stone above and protect the tomb from collapse. As far as the building itself is concerned, there is obviously no connection between this mausoleum and the Egyptian pyramids. The volume difference between the two is too great, and the mausoleum is completely piled up by large stones and needs lateral protection, which is different from the Egyptian pyramids.

In AD 413, the 19-year-old son of King Haotai, Changshou Aric Lian, ascended the throne. He reigned for 78 years and died at the age of 97. In ancient times, a long-lived old man was regarded as a human being, and a long-lived monarch was a symbol of the prosperity of the country.

The Longevity King continued the expansion policy of his father, King Haotai. In order to contain the gradually powerful Northern Wei Dynasty, Goguryeo supported the Beiyan regime. When Beiyan perished, Goguryeo’s army covered the evacuation of clans and people in the Longcheng of Beiyan National Capital. In the year before the Northern Wei Dynasty launched a war of subjugation against Beiyan, Changshou Wang sent envoys to visit the Northern Wei Dynasty to request the imperial edict. Later, although Goguryeo supported Beiyan, it caused dissatisfaction in the Northern Wei Dynasty. However, with the death of the last monarch of Beiyan, the two sides reconciled, and Goguryeo not only accepted the conferment of the Northern Wei Dynasty regime, but also accepted the conferment of the Southern Liu and Song Dynasties, maintaining a stable and balanced relationship between the North and the South.

During the Southern and Northern Dynasties, the Central Plains regime began to take "Korea" as the abbreviation of Koguryo, and Koguryo gradually took "Korea" as the official title. In order to prevent the invasion of the Northern Wei Dynasty and suppress Baekje and Silla better, in 427 AD, Changshou Wang moved the capital from Ji ‘an to Pyongyang. When he captured Baekje and occupied the Hanjiang River Basin on the Korean Peninsula, Goguryeo’s territory reached its peak.

Ride an electric car from Changshou Mausoleum and return to the city center, passing through some small aristocratic tombs along the way. There used to be a mural exhibition hall here, but it is no longer open. Tomb murals can be seen in Koguryo Museum. In 1997, the Koguryo Mausoleum in Ji ‘an was stolen, and the director of Ji ‘an Korean Cultural Center was also involved. Many murals were smuggled to South Korea, and some were destroyed in the excavation. Later, some China scholars discovered Koguryo cultural relics when they visited the museum in South Korea, and asked for them in vain.

Special tenderness

The Yalu River in Ji ‘an is very narrow, and people who are good at swimming come from the other side for dozens of times. At six o’clock in the evening, there was no one on the street in Ji ‘an. Looking across the bank, the North Korean side was more pure black.

During the day, the taxi driver took me to the port, opposite the city of Manpu, North Korea. The cement factory aided by the Soviet era was still working in the thick smoke, and the mountain was bare. The driver said that North Korea was worried that someone would escape, so it cut down all the mountains to facilitate surveillance.

In October, 2021, Ji ‘an, Jilin, Manpu City, North Korea, on the other side of Yalu River, the border river between China and North Korea, was a cement factory aided by the Soviet era.

Ji ‘an always gives me a different flavor from other cities in Northeast China, especially neat and orderly. Cars always give way to pedestrians, and even the morning market is very regular. Breakfast stalls and other stalls selling vegetables, meat and aquatic products, and mountain products specialties have their own positions and are clearly separated. At a certain moment, such a civilized scene gave me the illusion of acting. Looking at the neatness and order of Ji ‘an, I wonder if this norm is also the ideal state that the other side of the river yearns for.

In October 2021, Ji ‘an, Jilin, was a morning market in the urban area.

But not everyone appreciates this specification. A taxi driver told me that the city’s economic situation is not good, and the real estate development that has been heated up around North Korea’s reform and opening up has always been a dream. After the epidemic, basically only tourists from the province came. What doesn’t match the high-level world cultural heritage is the lack of entertainment services that can retain tourists’ consumption. Moreover, the history of Koguryo is relatively unpopular, and many tourists just stop by to see the ruins and go to other places to stay. When the government was unable to develop the economy, it began to attach importance to the construction of civilization. Although the local people enjoyed cleanliness and order, they also had a tired response.

In this way, what I see is more like "we are very happy here, and only happiness is allowed."

In October 2021, Ji ‘an, Jilin, when night fell, there were no people on the street.

But in my feelings as a foreigner, Ji ‘an has a special gentleness. Perhaps because of the vigorous development of tourism construction, its public service facilities are completely high-level even compared with first-tier cities, with clean streets, clean and adequate public toilets, clear and perfect tourist guide signs, and Koguryo Museum with unique appearance. This public museum is charged, which is rare. The advantage is that there is no reason not to open on Mondays, which is more convenient for tourists to arrange their time.

In addition, the natural environment here is very pleasant, with mountains and rivers, warm in winter and cool in summer, and long T-shirts in late autumn during the day. No wonder Koguryo built the capital here. This place is very suitable for literary and artistic creators to move in for a short time, concentrate on their work, climb mountains when they are tired, and walk by the river.
