CCTV News:On August 17, 2022, Shen Zhanli, spokesperson of the Emergency Management Department and director of the Press and Publicity Department, introduced at the press conference that in July, floods and hailstorms were the main natural disasters in China, and droughts, typhoons, earthquakes, geological disasters and forest fires also occurred to varying degrees. A total of 16.92 million people were affected by various natural disasters, 90 people died and disappeared due to disasters, and the direct economic loss was 28.59 billion yuan.

　　In July, the national natural disasters mainly showed the following characteristics: First, floods occurred in the north and south, local losses in Liaoning and Sichuan were heavy, floods in major rivers were generally stable, and local flash floods caused casualties. Second, there have been 10 strong convective weather processes in China, which are more than the same period of normal years. Wind power disasters are widespread and lightning strikes are more prominent. Third, the number of landing typhoons is small. Typhoon Siam is the first typhoon to land in China this year, with a wide range of influence, long duration and large accumulated rainfall. Fourth, the number of high-temperature days is more than normal, and early love occurs in Sichuan, Chongqing and Yunnan. Fifth, there were two earthquakes with magnitude above 5.0 in mainland China, and no casualties were caused.

　　In July, the national production safety situation was relatively stable, with 1912 production safety accidents and 1609 deaths. The number of accidents, major accidents, major accidents and deaths all decreased year-on-year. However, from the typical accidents, some hidden dangers are still outstanding: First, the major hidden dangers in the mining field are not well managed, and the problem of illegal mining is outstanding. On July 23, a major accident of slope collapse occurred in Gansu Baiyin Hongsheng Coal Industry Co., Ltd., causing 10 deaths, and major accidents of illegal mining in metal and non-metal mines occurred in some places, causing casualties. Second, road transport accidents are frequent, of which 7 become major freight accidents; In addition, the summer travel and play have increased, and the risk of tourist passenger transport has been concentrated. Third, frequent gas leakage and explosion accidents, illegal construction in some places leads to gas leakage, and improper maintenance and use of gas equipment in production and business premises and residential areas are prominent. Fourth, disasters and accidents caused by extreme weather are frequent, especially the safety measures in tourist attractions are not in place, which leads to tourists’ distress, and water transportation and adventure navigation operations cause casualties.

CCTV News:With the arrival of summer, strong convective weather is frequent, and lightning disasters also need attention. So how is the lightning disaster produced and how to prevent it? Let’s get to know the relevant knowledge through a set of hand-drawn animations.

Lightning is an ultra-long distance discharge process in the atmosphere. Lightning has powerful current, scorching high temperature, strong electromagnetic radiation and violent shock wave, which makes it instantly become a "wreck-it ralph", causing lightning disasters. Cloud — Lightning, that is, when there is a discharge between the cloud and the earth, will have a great impact on human activities. Lightning strike can also change into a pattern, and it can be attacked by direct lightning strike, contact voltage, side lightning strike and step voltage. Lightning electromagnetic radiation may also interfere with and destroy the computer system and its data storage.

How do I know how far this dangerous lightning is from me?

Lightning and thunder were born at the same time, but they didn’t run as fast. Light can travel about 300,000 kilometers per second, while sound can only travel about 340 meters per second. Therefore, if you see lightning and hear thunder every 10 seconds, this thunderstorm is about three or four kilometers away.

If you are not sure of the time, you can also listen to the sound to feel it. When the lightning is close, it hears a sharp crack, and when it is far away, it is a rumbling sound. Generally speaking, if thunder can be heard, it will be within 10 kilometers. When encountering lightning weather, it is best not to use the solar water heater on the roof again, because water can conduct electricity and there is a hidden danger of lightning strike.

If you can’t find a suitable and safe lightning protection place outdoors for a while, you can try to squat down, bow your head, put your feet together and tuck your knees in your hands to avoid the "step voltage" damage caused by lightning. Because, when lightning is released from the cloud to the earth, it will produce a potential field, and the closer it is to the lightning point on the ground, the higher the potential is. If the site potentials of the two feet are different when lightning strikes, this potential difference will generate a voltage between the two feet and a current will pass through. The greater the distance between the feet, the greater the step voltage.

As the saying goes: it is not advisable to get off the bus to avoid the rain, and the car entertainment should be closed; All the windows should be closed tightly, and it can’t ride a bicycle or motorcycle; Don’t walk too high with an umbrella, and remove all metal ornaments; If lightning and thunder are similar, squat down and tuck your head to avoid.

　　Covering 11 provinces and cities along the Yangtze River and spanning three major plates, the Yangtze River Economic Belt not only has outstanding ecological status, but also has great development potential.

　　In the past five years, under the strong leadership of the CPC Central Committee, the provinces and cities along the Yangtze River have made historic achievements in "jointly protecting and not developing" and promoting the overall green transformation of economic and social development. The economic development of the Yangtze River Economic Belt is generally stable and the structure is optimized.

　　Break the dilemma

　　Chemical industry is no longer "encircling the river"

　　The total length of the Yangtze River in Changzhou, Jiangsu Province is only 25.8 kilometers, but there are 84 chemical production enterprises, which are very dense.

　　In the Binjiang Chemical Industry Park in Xinbei District, Changzhou City, Gao Xiaoping, a villager from Xinhua Village, said that enterprises have invested and made local residents rich; "Chemical encircling the river" has made residents suffer from environmental pollution.

　　"Crack ‘ Chemical wai Jiang ’ We are duty-bound. " Xu Yawei, secretary of the Party Working Committee of Changzhou Binjiang Economic Development Zone, said that the number of chemical enterprises in the development zone has decreased from 84 in 2019 to 41 by the end of 2020. "Shut down and turn around, the first thing to change is the development concept."

　　Such measures in Changzhou are not uncommon in provinces and cities along the Yangtze River. In the past, petrochemical, steel, smelting and other industries gathered on both sides of the Yangtze River, with a large pollutant emission base, and wastewater, chemical oxygen demand and ammonia nitrogen emissions accounted for 43%, 37% and 43% of the country respectively. To give priority to ecology and green development, we must solve the dilemma of "chemical industry encircling the river".

　　Upstream, the original chemical factory building in Linxiang Industrial Park, Linxiang City, Hunan Province is being transformed into a logistics base. Since 2018, Linxiang Industrial Park has stopped all newly started chemical projects within 1 km of the Yangtze River coastline. By the end of December 2020, nine chemical enterprises had taken the lead in withdrawing according to the plan. In Jiujiang City, Jiangxi Province, 37 small chemical enterprises within 1 km along the Yangtze River, Poyang Lake and Xiuhe River have all closed down at the end of 2019. The chemical industry once contributed nearly one-third of the industrial output value of Yichang City, Hubei Province. In 2017, Yichang formulated a three-year action plan for 134 chemical enterprises along the Yangtze River, and proposed measures such as shutting down a batch, transforming a batch on the spot, relocating a batch to the park, and changing production to a batch. This work is now nearing completion. Hubei Province proposes to complete the customs clearance and relocation of chemical enterprises within 1 km along the Yangtze River by December 31, 2020, and promote the customs clearance and relocation of chemical enterprises within 1-15 km along the Yangtze River by the end of 2022, so as to solve the outstanding problem of "chemical encircling the river" within three years.

　　The banks of the Yangtze River, where machines roared and pipelines formed a network, are now gradually returning to peace. At the same time, new industries are rising and new kinetic energy is surging, and the provinces and cities along the Yangtze River are competing to embark on the road of green development.

　　Seek high-quality development

　　On November 23, 2020, after 10 hours of intense debugging, the 0.18 mm ultra-thin electronic glass production line of Yichang CSG Optoelectronic Glass Co., Ltd. successfully reached the standard for mass production. Guangzhou Automobile Passenger Car Yichang Branch has become a benchmark factory for energy-saving and environment-friendly intelligent manufacturing, which can produce a car every 52 seconds … …

　　After the chemical industry was changed and moved, these alternative industries quickly made up the position. At present, the output value of new materials, biomedicine, electronic information and advanced equipment manufacturing accounts for 41.9% of Yichang’s total industrial output value. According to the Ministry of Ecology and Environment, from January to September 2020, the proportion of days with excellent air quality in Yichang was 88.3%, up 21.3% from the same period in 2019.

　　Tongling City, Anhui Province, named after copper, is prosperous because of copper. With the development of the industry entering the bottleneck period, how to promote industrial upgrading and achieve high-quality development has become a new topic in Tongling.

　　"The industry needs to be transformed and copper foil needs to be developed, but we have no technology. What should we do?" For a while, Jia Jintao, the head of Tongguan Copper Foil Company, was puzzled by product innovation. Yuansheng Jin, head of high-tech department of Tongling Science and Technology Bureau, found that many copper enterprises are facing the same problem of scientific and technological innovation. "From the production of electrolytic copper to the research and development of copper foil and copper plate, improving the added value of products is the key."

　　Tongling Science and Technology Bureau included Tongguan Copper Foil Company in the application guide of key scientific and technological projects, and borrowed money from universities and research institutes. Jia Jintao said, "With the help of experts and professors, the company’s electronic copper foil stress research project has been carried out smoothly, and I am full of confidence in the next development!"

　　At present, Tongling is actively introducing deep processing projects of copper-based new materials, gradually getting rid of the primary processing stage of raw materials, and forming many industrial chains such as "plate, belt, tube, rod, wire, foil and powder". Recently, Tongling has issued a plan to promote the deep integration of copper-based new materials industry with new energy vehicles, electronic information and high-end equipment industries, and increase the added value of products.

　　Changzhou Binjiang Chemical Industry Park shut down the chemical plants within 1 km along the Yangtze River and withdrew the coastline of the Yangtze River, which gave two enterprises of Wuxi Xingda Group a "new life" in the park. Xingda Group is determined to shut down two old factories and invest 3 billion yuan to rebuild new projects in different places in the park. According to the relevant person in charge, the new plant has opened up the upstream and downstream industrial chains, which not only reduces the cost and safety risks, but also reduces the discharge of wastewater and waste gas through new processes. According to estimates, after the completion of the new project, the annual sales of the enterprise will reach 6.5 billion yuan, the annual tax payment will be about 230 million yuan, the average tax revenue per mu will exceed 1 million yuan, and the wastewater emission reduction will exceed 20%.

　　Jiujiang city put an end to "polluted" GDP and fiscal revenue. In recent years, Jiujiang has rejected more than 400 investment projects that have a negative impact on the ecological environment, leaving the development space along the Yangtze River to emerging industries led by port economy and digital economy. On the south bank of the Yangtze River and the west bank of Poyang Lake, a Poyang Lake Ecological Science and Technology City with a planned area of 158.53 square kilometers is emerging, and leading enterprises have settled in. "It turned out that attracting investment from all over the world was only an economic account. Now it is a political account, an ecological account, a social account and a long-term account." Wu Bin, director of the Office of the Leading Group for Open Development along the Yangtze River in Jiujiang, said.

　　Promote synergy

　　Dancing upstream and downstream

　　Every day, Chongqing Minsheng Shipping Company has cargo ships departing from Chongqing Orchard Port, descending along the river, transshipping at Jiangsu Taicang Port and then heading for Shanghai Yangshan Port.

　　At the beginning of 2020, Chongqing Orchard Port, Taicang Port and Shanghai Port opened the "Shanghai-Chongqing Direct Express Line". "On average, it runs every day. Compared with ordinary liners, the overall logistics timeliness has increased by more than 30%." Niu Xiandan, general manager of Chongqing Orchard Port International Logistics Hub Construction and Development Co., Ltd. said that in the future, the mechanism will be innovated to reduce the waiting time for ships to wait for the gate and change ships, and the voyage will be compressed for another two to three days.

　　In Taicang Port and Yangshan Port downstream, the new customs clearance mode has also reduced the transportation time by at least two days. On November 4, 2020, 23.47 tons of red oak board arrived in Taicang Port from Yangshan Port, which is the first time that Yangshan — The first order after the formal operation of Taicang Port’s "linkage loading and unloading" supervision mode marks the comprehensive landing of customs clearance integration between Shanghai and Taiwan.

　　"Taicang Port is an extension of Yangshan Port. After the imported goods are released in Yangshan Port, they can be directly transported to Taicang Port by special barges. The export goods arrive at the wharf of Taicang Port. After the customs declaration is released, they can leave the country directly from Yangshan Port. " Vivi, Deputy Chief of Logistics Management Section of Taicang Customs, said that this mode has solved the problems of customs declaration and second arrival, which can greatly save the logistics cost and customs clearance time of enterprises.

　　The Yangtze River, a water transport artery that runs through the east and west, is a rare golden waterway in the world, and its freight volume ranks first among inland rivers in the world. In the past five years, the provinces and cities along the Yangtze River have made great efforts to promote coordinated development and add color to this golden waterway.

　　Sichuan and Chongqing have innovated the inter-provincial consultation and cooperation mechanism, established the three-level operation mechanism of Sichuan-Chongqing cooperation to promote the construction of the twin-city economic circle in Chengdu-Chongqing area, including the joint meeting of the party and government, the coordination meeting of executive vice-provincial mayors and the joint office, and promoted 31 major projects jointly implemented by Sichuan and Chongqing, with a total investment of about 556.3 billion yuan.

　　Such a mechanism is being promoted in the upper and lower reaches of the Yangtze River. The National Development and Reform Commission, together with 11 provinces and cities along the Yangtze River, established the "1+3" inter-provincial consultation and cooperation mechanism in the Yangtze River Economic Belt, and achieved a number of achievements in joint prevention and control of ecological environment, interconnection of infrastructure, and joint construction and sharing of public services. Three provinces and one city in the lower reaches of the Yangtze River took the lead in establishing a cooperation and coordination mechanism of "three-level operation, unification and separation, pragmatism and high efficiency"; Four provinces and cities of Chongqing, Sichuan, Guizhou and Yunnan in the upper reaches of the Yangtze River signed an agreement to establish an inter-provincial consultation and cooperation mechanism in the upper reaches of the Yangtze River; Jiangxi, Hubei and Hunan provinces in the middle reaches signed an agreement to establish an inter-provincial consultation and cooperation mechanism in the middle reaches of the Yangtze River … …

　　The institutional mechanism has been broken, and the multi-level consultation and cooperation mechanism framework has taken shape. The upstream and downstream of the Yangtze River Economic Belt are working together to develop a new chapter.

　　The report of the 19th National Congress of the Communist Party of China pointed out that Socialism with Chinese characteristics’s entry into a new era means the continuous development of Socialism with Chinese characteristics’s roads, theories, systems and culture, which has expanded the way for developing countries to move towards modernization, provided new choices for countries and nations in the world who want to speed up their development and maintain their independence, and contributed China wisdom and China’s plan to solving human problems. It can be said that the success of China Road is changing the inherent view of the world on the road of human social development, especially the road of modernization, and more and more showing its world significance. For China scholars, it is not only a very important political task, but also a very serious academic research.

　　Clarifying the road of China is of great significance to the development of China and the world.

　　Today, China is increasingly connected with the world. Explaining the road of China to the world is of great significance to the development of China and the world today.

　　The objective need for China to approach the center of the world stage and play a greater role. After 40 years of hard struggle and exploration of reform and opening up, China has created an earth-shattering miracle in the history of human social development. The level of social productivity has improved significantly, the people’s living standards have improved significantly, and its international influence and voice have improved significantly. Especially since the international financial crisis broke out in 2008 and China surpassed Japan to become the second largest economy in the world in 2010, China’s international status has become increasingly prominent, and it has approached the center of the world stage with a more steady and confident pace. In today’s world, China plays an irreplaceable and constructive role in promoting economic globalization, handling major international affairs and building a more just and reasonable international order. It is hard to imagine what the world would be like without China. Therefore, China needs to convey more China voices to the world, better display China’s national image, and let the world know more about China, accept China and recognize China.

　　To provide the world with the wisdom of China and the practical needs of China’s plan. As Comrade Supreme Leader said, "The world is so big and there are so many problems, and the international community is looking forward to hearing China’s voice and seeing China’s plan". At present, the economic recovery of major developed countries is slow, and economic and social development encounters various difficulties, which makes it more urgent for mankind to explore a better social system. The vast number of developing countries not only have similar historical circumstances to China, but also face unavoidable and unavoidable problems of governing the country, such as how to develop the economy, improve people’s livelihood and maintain stability. In contrast, the development of China has accumulated many successful experiences that are effective and worthy of long-term persistence, and won universal praise in the world. The successful practice and valuable experience of China Road show China’s wisdom, provide valuable reference experience for global governance, and set a very rare and good model for the world, especially the developing countries, to explore the development path in line with their own national conditions. As China approaches the center of the world stage, it is in such a big trend that leads the world. China scholars should enhance their confidence and ability to explain the road of China to the whole world.

　　It is necessary to clarify the prejudice and misunderstanding of China in western society. How to solve the difficult problem of realizing modernization in a populous, poor and backward country? There is no precedent in the world. China not only solved this problem, but also did it well. Today, China has made great achievements that attract worldwide attention in its modernization drive and made important contributions to world development. However, due to ideological prejudice, even for ulterior political purposes, some western forces are used to looking at China’s road and China’s development through "colored glasses", and "China’s collapse theory" and "China threat theory" are endless, and the phenomena of questioning, accusing and even attacking China are one after another. China scholars can’t turn a blind eye to this, let alone let it go. China scholars can make great achievements in clarifying prejudice and misreading. We should interpret the code of China’s development and the value of China Road through academic communication and dialogue, so as to avoid the misunderstanding, misreading and misunderstanding of China in western society to the greatest extent.

　　To clarify the road of China, we must grasp several aspects

　　To explain the road of China to the world, we must solve the problem of what to say. From the actual situation, we need to grasp the following aspects.

　　China Road is a hard-won road. The road of China did not fall from the sky, but the correct road suitable for the national conditions of China was found by the Communist Party of China (CPC) who led the people of China to go through all kinds of hardships and pay all kinds of costs. This road was formed through continuous practical innovation and theoretical exploration led by generations of the Communist Party of China (CPC) people. It is full of suffering and glory, twists and turns and victories, dedication and gains. It is the correct road that has been tested by practice and is hard-won and precious. China Road with a strong sense of history is both a historical necessity and a choice of the people. The people of China must cherish it and never make subversive mistakes.

　　China Road is a road with unique advantages. China Road has unparalleled unique advantages. For example, from the economic system, the socialist market economic system gives full play to the role of the market and the government, which not only ensures economic vitality, but also ensures macroeconomic stability, and is an advanced economic system. From the political system, China’s political party system is advanced and successful. The multi-party cooperative political party system led by the Communist Party of China (CPC) can carry forward democracy and brainstorm ideas, and at the same time can avoid the problems of continuous party struggle and low efficiency caused by the western two-party system and multi-party system. From the perspective of cultural system, Socialism with Chinese characteristics’s cultural construction not only ensures the guiding position of Marxism, but also stimulates the cultural innovation and creativity of the whole nation and promotes the prosperity of socialist culture. China Road follows the basic law of the development of human society, conforms to the trend of peace, development, cooperation and win-win, and can properly handle the major relations in economic and social development, so it has unlimited bright prospects and will surely become wider and wider.

　　China Road is a road that benefits the people. China’s road has rich connotations, colorful theoretical elements and profound China wisdom. China Road is committed to meeting people’s growing needs for a better life, enhancing people’s well-being, promoting people’s all-round development, and gradually achieving common prosperity for all people. China Road insists on rallying people’s strength, respecting people, relying on people, for people, and realizing people’s fundamental interests as the starting point and the end result. Judging from the historical process since the reform and opening up, it is precisely because our party conforms to the people’s yearning for a better life and upholds the people-centered development thought that it can fully mobilize the people’s enthusiasm, initiative and creativity to participate in socialist modernization and enable the people to enjoy more and fairer development results. As far as poverty alleviation is concerned, over the past five years, China has steadily lifted more than 68 million poor people out of poverty, and the incidence of poverty has dropped from 10.2% to 3.1%. The reason why China Road shows more and more energy lies in the active recognition, heartfelt support and full participation of the people.

　　China Road is a way to contribute to the world. In recent years, with the deepening of reform and opening up, China’s national strength has been continuously enhanced, its influence has been continuously enhanced, and its contribution to the world has been increasing day by day. "What can China Road contribute to the world" has become the "question of the times" that must be answered today. Generally speaking, China Road has made at least five historic contributions to the world: survival contribution, development contribution, institutional contribution, cultural contribution and peaceful contribution. China advocates diversity in the world, equality among countries, mutual learning among civilizations, inclusive development and mutual benefit, and promotes the building of a community of human destiny. In recent years, China’s foreign trade, foreign investment and foreign exchange reserves rank among the top in the world, contributing more than 30% to world economic growth. This is a powerful proof of China’s contribution to the world. China solved the difficult problem of modernization with Marxist wisdom and oriental wisdom, and changed the modernization mode from single choice to multiple choice, which promoted the diversity of human civilization development.

　　Enhance academic self-confidence and impress people with academic theory

　　China scholars can explain the road of China to the world clearly, instead of shouting slogans, talking to themselves and imposing on others, they must strengthen academic expression, dissemination, communication and dialogue, explain facts with academics and impress people with academic theories.

　　Enhance academic self-confidence. Comrade Supreme Leader pointed out in the report of the 19th National Congress of the Communist Party of China that after long-term efforts, Socialism with Chinese characteristics has entered a new era, which is a new historical orientation for China’s development. China scholars should firmly grasp the fundamental change of Socialism with Chinese characteristics entering a new era, build a solid ideological foundation, enhance road confidence, theoretical self-confidence, institutional self-confidence and cultural self-confidence, tell the story of China well from the historical position of the new era, and systematically explain the road of China from the height of the whole world. Where does confidence and confidence come from? The great achievements from Socialism with Chinese characteristics’s practice come from the unique advantages of looking at the world scenery. China scholars should construct China’s own academic system and discourse system, explain China’s experience and contribute China’s wisdom to the international community, and fully reflect China scholars’ academic responsibility and academic attainments. We should use China’s academic thought to tell the story of China, spread the voice of China and contribute China’s academic gift to the world.

　　Learn from academic achievements. China’s development achievements have attracted the continuous attention of the world, especially the attention of international academic circles. Overseas, there has been an upsurge of research on China, and many well-known institutions and scholars have achieved considerable positive results. China scholars should persist in not forgetting the original, absorbing foreign countries and facing the future, and deepen the study of China Road and contemporary China issues. We should not only base ourselves on the reality of our country, but also open the door to engage in research; We should not only pay attention to originality, focus on me, but also be eclectic and use it for us, actively learn from and absorb the research results of overseas scholars. For example, in recent years, the latest research results of overseas scholars on China model, China experience, China’s economic development, China’s democratic political construction and the construction of the ruling party have certain enlightenment and reference significance in terms of perspectives, methods and opinions, which can be a reference for us to strengthen academic research. China scholars should enhance their awareness of openness and international communication, insist on focusing on themselves and learn from them extensively, so as to make China’s academic discourse, academic system and academic achievements more contemporary and international, and more easily accepted by international academic circles and the international community.

　　Strengthen academic exchanges. With the development of China, the discourse power of China scholars is changing profoundly from being unqualified, soliloquizing and unable to say aphasia to being partially led. This transformation process is actually a process in which China’s academics are led by theory defense and theory explanation. To achieve theoretical guidance, express China’s words to the world, interpret China’s plan and explain China’s road clearly, we need to "go out" and "please come in", and attach great importance to academic exchanges and mutual learning. It is necessary to build an academic exchange platform, actively participate in international bilateral and multilateral academic activities, make full use of international forums, forums and conferences at all levels, establish a long-term and stable high-end academic dialogue mechanism, and improve the quality of academic exchanges; Broaden the field of academic exchanges, fully express China’s values, and advocate and enhance the community consensus on human destiny; Strengthen exchanges between think tanks at home and abroad, guide influential and convincing academic achievements to go abroad, promote overseas China studies, and let the world know China and China better.

　　Accelerate academic innovation. Time is the mother of thought and practice is the source of theory. The vitality of theory lies in innovation. China scholars should uphold the scientific attitude and method of doing scholarly research, earnestly enhance their sense of innovation, fully embody China’s characteristics, China’s style and China’s style in academic propositions, academic ideas, academic viewpoints and academic discourses, constantly summarize and refine new concepts, new categories, new systems and new expressions, effectively enhance the innovation and affinity of academic achievements, and demonstrate the responsibility of China scholars in accurately explaining China’s road. Comrade Supreme Leader pointed out: "We should focus on the major issues facing the development of China and the world, and strive to put forward ideas, propositions and plans that can reflect China’s position, China’s wisdom and China’s values." China scholars should strengthen academic accumulation, lay a solid academic foundation, cultivate academic ethics, broaden their academic horizons, pay attention to the integration of history and reality, theory and practice, and improve the explanatory power of academic achievements. Give full play to professional characteristics and academic expertise, further refine and optimize the discourse of external publicity, jump out of the pattern of interpreting the reality of China with western discourse, and strive to make more high-quality academic achievements that people who care about the road of China and the development of China love to read.

　　(Author: Socialism with Chinese characteristics Thought Research Center of the New Era, the Supreme Leader of the Central Party School)

　　 　For some time, the drought in many places in China has developed rapidly, superimposed with high temperature and heat damage, which has adversely affected the production and life of many people. A few days ago, the Ministry of Agriculture and Rural Affairs, the Ministry of Water Resources, the Emergency Management Department and the China Meteorological Bureau jointly issued an urgent notice, demanding that the relevant areas do their best to prevent and reduce disasters, go all out to win the battle against high temperature, heat, drought and harvest of autumn grain, and clearly put forward that we should do everything possible to broaden drought-resistant water sources, strengthen the scientific dispatching management of water sources such as rivers, lakes and reservoirs, and strive to ensure the demand for agricultural irrigation water.

　　 　"Thirst" cannot be delayed, and ensuring people’s water use is the top priority. Allowing rural residents to drink "safe water" and "safe water" for a long time is the basic premise of getting rid of poverty, an important content of realizing rural revitalization, and the proper meaning of protecting farmers’ rights and interests. In addition, as the saying goes: "Spring drought is not a drought, and autumn drought is halved." To prevent the autumn grain from decreasing production, we must do our best to fight drought and win the battle of autumn grain harvest.

　　 　Earlier, the person in charge of the relevant departments of the Ministry of Water Resources said that the drinking water safety situation of rural people in drought-stricken areas had been comprehensively explored, so as not to miss one household or one person. It is an urgent and important task to solve the drinking water difficulties of urban and rural residents and let the people drink "safe water" and "safe water".

　　 　According to the news from all sides, many places have also acted quickly. From water storage and water conservation, to water replenishment, to water supply by turns and emergency water supply in sections and districts, in order to ensure the people’s water use. In addition, from opening up new water sources, to time-sharing water supply, and then to pulling water to deliver water, relevant local departments have also introduced targeted measures according to local conditions to minimize the impact of drought.

　　 　Some implement artificial precipitation enhancement to "quench thirst" for the land; Some are "well organized" to fight drought, and "big wells, small wells, deep wells and old wells are together"; Others mobilize scientific and technical personnel to show their strength at critical moments. For example, agricultural technicians help growers to use water sources such as wells, rivers, ponds and canals to replenish water for irrigation, timely topdressing panicle fertilizer, and strengthen pest control and monitoring. Drought resistance and bumper harvest, proper measures and comprehensive efforts can achieve great results.

　　 　It should also be noted that it is difficult to achieve the expected results by individual strength alone in dealing with this drought. Farmers everywhere took action spontaneously, and their spirit was commendable. However, it is necessary to unite the group to fight drought, especially the relevant departments should organize capable personnel, mobilize the forces of all parties, and form a huge and sustained joint force to maximize the effectiveness of drought relief. In this process, we must also fight drought scientifically, spend money on the cutting edge and use our strength in critical areas.

　　 　Drought resistance is not a matter of one department, but needs multi-department linkage. The emergency notice issued by the 4 departments this time reflects this point. The water conservancy department should strengthen the scientific dispatching management of rivers, lakes, reservoirs and other water sources, the emergency department should preset emergency response forces and materials and equipment for flood control and drought relief, the meteorological department should dispatch operational aircraft to the severely drought-stricken areas in time, and the agricultural and rural departments should further improve the technical guidance for fighting disasters and harvesting crops. While completing their own work, they should also hold hands with each other and strengthen linkage to better cope with this round of drought.

　　 　China is a country with frequent floods and droughts, and has accumulated rich experience in the long-term drought relief process. However, in the face of this rare serious drought, we must not be the slightest bit careless. It should be admitted that it is not easy to do a good job in drought early warning and strengthen risk management, but it does not mean that human beings can only do nothing. We should vigorously fill shortcomings, plug loopholes, and improve drought resistance, optimize drought resistance means with the greatest strength, and introduce advanced technology to effectively reduce the harm caused by drought.

　　 　Strengthening the prevention and control of natural disasters is related to the national economy and people’s livelihood, and to everyone’s life safety. Drought is the command. We should not only make strategic preparations for "fighting against severe drought and long drought", but also try our best to refresh more effective "fighting methods" in tactics, improve the drought-fighting effect and fully protect the national economy and people’s livelihood.

Let’s take a look at the author’s summary.

OMS issue documents will have several key nodes, and the corresponding logic needs to be completed at different nodes to ensure the subsequent normal circulation of documents.

In cross-border e-commerce OMS, the key points are: logistics ordering, freezing of withholding funds, locking, release and deduction of inventory, etc. An article has been written before logistics ordering.This time, let’s talk about locking, releasing and deducting inventory..

For cross-border e-commerce overseas warehouse OMS, there are generally several scenarios for inventory locking:

1. Lock the inventory when it is created;
2. Place an order for logistics, and lock the inventory when obtaining the logistics list;
3. Lock the inventory when submitting the outbound order to WMS.

There will be different business scenarios for different customers, so the inventory locking is generally different. These three scenarios are not optional, but all three, and they should be flexibly combined.

If some customers are strict and want to occupy some inventory when creating the outbound order, they will lock the inventory after creating it.

Some customers have no special requirements for inventory locking, so the normal situation should be to lock the inventory when they get the logistics list.

There are also some customers who may upload their own logistics sheets or do not require logistics sheets, so they can set to lock the inventory when submitting the outbound order to WMS.

It is suggested that the timing of inventory locking should be made into a policy rule. Every time a different customer is introduced, the corresponding rule can be configured. If there is no configuration rule, the default node will be adopted, which can flexibly take into account the needs of different customers.

With the lock of inventory, there will naturally be the release of inventory. In fact, the locking and releasing of inventory can be divided into two groups. The first group is locking and releasing, and the second group is locking and deducting.

The inventory is locked, which means that the outbound order occupies this part of the inventory, and the system needs to mark it as locked to prevent it from being preempted by other outbound orders. So if I cancel the outbound order, I need to release the lock of this block, so the corresponding release of inventory lock actually refers to the scene where the outbound order is cancelled or intercepted.

If this outbound order is completed, the corresponding inventory needs to be deducted. At this time, the locked part will be converted into the deducted part, which is equivalent to emptying the locked quantity first, then increasing the deducted quantity (inserting the inventory flow), and finally the available inventory will remain unchanged.

Here we need to pay special attention to two issues, one is the timing of release, and the other is the quantity of release.

Regarding the timing of release, for the cancellation or interception of the outbound order, when the cancellation or interception is successful, then release it. For the normal issue of outbound order, we need to pay attention to one question:How to define outbound?

On the surface, the goods leave the warehouse, which is called outbound. However, in the actual business scenario, it may take a day or two for the goods to be picked up by the logistics provider after picking and packaging, and the outbound node will be late at this time. It may also be taken away by the logistics provider, but there is no rigorous handover action, resulting in some outbound documents not marked as outbound, so they have been in a state of waiting for outbound, and inventory cannot be deducted.

How WMS defines outbound will affect when OMS deducts inventory, so this piece needs to be combined with business to explore an optimal solution. If the "delivery" is too early, the time period for customers to intercept the delivery will be very short, and the actual goods will not go out, but they cannot intercept the delivery, which will increase losses in vain; If "outbound" is too late, it is possible that some outbound documents will be marked as overtime outbound, which will affect the rating of platform stores.

Regarding the quantity released, for overseas warehouses of cross-border e-commerce, there is basically no so-called partial outbound or multi-batch outbound, and most businesses are issued in a single order and completed at one time. So don’t expand here, just make a reminder.If the issue quantity does differ, it is necessary to ensure that the actual available inventory quantity is accurate in consideration of the locked quantity, and the difference can be adjusted by some exception handling methods.

In-transit inventory is a link that is easily overlooked by everyone. Sometimes, I even feel that this data is useless, and then I forget that there is such a thing when designing some logic.

I’ve been looking for information about in-transit inventory on the internet for a long time, and it turns out that many articles seem to be shallow or complicated, which makes it particularly uncomfortable to understand.

Here, I would like to sum up how the in-transit inventory in overseas warehouses of cross-border e-commerce is generally used within my personal knowledge. It is only my personal opinion, so please pay attention to dialectical treatment.

If you want to simply understand the in-transit inventory, it is enough to analyze it directly from the two most common ways to produce the in-transit inventory. They are:

1. Allocation is on the way;
2. Purchasing is on the way.

Transfer in transit is the in-transit inventory generated in the process of transferring from warehouse A to warehouse B. For warehouse a, the goods have left warehouse a, so the inventory of warehouse a has been deducted; For warehouse B, the goods are on the way to transport, but they have not been put into storage yet, so they cannot be counted as available inventory, but only in transit.

There are many similarities between purchase in transit and transfer in transit, both of which are sent from one place to another. It’s just that the purchase involves some settlement problems with external suppliers, so it’s a little troublesome. For the warehouse that is about to receive the purchased goods, the goods are still on the road and have not been put on the shelves, so it can’t be counted as available inventory, but only in transit.

In-transit inventory can estimate the inventory in the future for a period of time to guide the sales decision; In-transit inventory will also occupy the cost of capital, so the financial department will pay attention to and attach importance to this piece of data.

For cross-border areas, because the process of stocking goods to overseas warehouses (the first journey) takes a long time, the controllability of in-transit inventory is particularly important for sellers. In addition to counting the actual available inventory of each overseas warehouse, we also need to pay attention to this part of the inventory in the process of stocking, and make an inventory plan in time.

For OMS, the definition of in-transit inventory generally refers toAfter the receipt document is submitted to the warehouse, but before the warehouse receives the goods, the total inventory in this period of time..

If the warehouse is actually put on the shelves, the in-transit inventory will be converted into available inventory. If the actual receipt of goods in the warehouse is less than the forecast quantity, but the receipt document is forced to end, then the inventory in transit needs to be reduced accordingly. Because the receipt document has been closed, the in-transit inventory should be converted into available inventory according to the actual quantity on the shelves, and the extra part should be invalidated and released because it can no longer be put on the shelves.

Schematic diagram of inventory change in transit

For OMS, it is important to pay attention to the number of SKUs whose receipt status is submitted between shelves. This part needs to dynamically adjust the number of in-transit inventory according to the actual number of shelves fed back by the warehouse, and finally pay special attention to some nodes of differential receipt and differential shelves.

In OMS outbound, the logistics ordering and rule engine are the most complicated, and the locking and releasing of inventory is the most basic requirement, so I didn’t write anything too deep, just briefly summarized and reviewed the past project experience.

In fact, the logic of locking and releasing the inventory is the same as that of withholding fees from the issue document. After locking the inventory, the corresponding fees will be frozen, and after releasing the inventory, the frozen fees will be released or deducted accordingly. It’s just that the content involved in billing is partial and the content is miscellaneous, so I won’t talk much here.

And the inventory on the way is because there are really too few online materials, so I made a fool of myself again and output some of my own shallow views and opinions.

I hope this article can help you. See you next time!

　　Liu Yurui, Chief Reporter of Jimu News

　　On January 7, Xiaoman (a pseudonym), a 2-year-old girl from Liaocheng, Shandong Province, was still receiving treatment in the hospital.

　　A month ago, Xiaoman and his uncle attended the wedding banquet in the village. Unexpectedly, after returning home, Xiaoman showed symptoms of poisoning, and the hospital diagnosed it as tetramine poisoning.

　　While treating Xiaoman, he reported the case to find the murderer. But as a result, Xiaoman’s father couldn’t figure it out.

　　The police said that this was a criminal case of intentional homicide. The suspect is Xiaoman’s uncle.

　　Receipt of acceptance

　　Candy at the wedding banquet

　　Xiaoman lives in Chenmiao Village, Douhutun Town, Liaocheng City, Shandong Province. At the age of 2, she is deeply loved by her elders.

　　On December 9, 2021, Mr. Hua (a pseudonym), a villager in the same village, held a wedding banquet, and Xiaoman’s uncle took her with him.

　　Xiaoman was treated in the hospital.

　　Xiaoman’s father told Jimu journalist that an old man gave Xiaoman a candy that day. About 20 minutes after Xiaoman ate it, she developed symptoms of physical discomfort, and her uncle took her home. Unexpectedly, after returning home, Xiaoman began to have convulsions, foaming at the mouth, blue face and other symptoms, and was then sent to the Pediatric PICU of Liaocheng People’s Hospital for rescue.

　　Soon the results came out, and the medical certificate issued by the hospital showed that Xiaoman was poisoned by tetramine. According to the data, tetramine was listed as a banned pesticide by the former Ministry of Agriculture and Rural Affairs as early as 2002 because it is highly toxic to humans and mammals and can cause secondary poisoning and environmental pollution.

　　Hospital diagnosis certificate

　　"The test results show that the content of tetramine in Xiaoman’s blood reached 876ng/ml." Mr. Man said that he immediately called the police.

　　Subsequently, after nearly 20 days of repeated transfer treatment, Xiaoman’s condition gradually stabilized. "My wife is a temporary teacher in kindergarten, who is mainly responsible for taking care of the safety of children." Mr. Man said that such a thing happened to his children, which was a great blow to his wife.

　　Xiaoman’s previous photos

　　The suspect is an uncle.

　　The filing notice shows that Dongchangfu Branch of Liaocheng Public Security Bureau has filed a case for investigation on December 10, 2021. The journalist noticed that the name of the case on the notice of filing was "12.09 intentional homicide".

　　At 9 o’clock on the evening of the 7 th, the journalist contacted the police investigating the case. He said that the case has been characterized as a criminal case, and the specific details are inconvenient to disclose.

　　Mr. Man recalled that on December 9, after Xiaoman was sent to the hospital, he found the candy wrapping paper that she had eaten that day in her daughter’s bag. "I gave the candy paper to the criminal police, and later they told me that there was something wrong with the candy." Mr. Man said.

　　The next day, the police found Mr. Man and told him that he had found the monitoring of the wedding banquet scene at the time of the incident. "I saw an old man acting suspiciously." Mr. Man said that he recognized it at that time. This is his uncle who lives near his home, that is, Xiaoman’s uncle.

　　"At that time, we couldn’t believe it, because even if we had contradictions, it was just trivial things." Mr. Man said that his family and uncle had a small dispute because of the trend of water pipes before, but he never thought that these were enough for him to poison Xiaoman.

　　Notice of filing

　　At present, the case is still under investigation by the local police. Xiaoman has been transferred to Shandong Provincial Hospital for rehabilitation treatment. "Now I can open my eyes." Mr. Man said that the previous treatment has cost nearly 150,000 yuan, and the future treatment of Xiaoman is conservatively estimated to need 100,000 yuan.

　　Mr. Man told reporters that the doctor also said that Xiaoman may not be able to fully recover. "There is a little hope, and we also want to try it." Mr. Man said.

1905 movie network news On the third day of the film’s release, it received a lot of praise. It is reported that the film is directed by, starring,, starring,,,,,, Sun Yue, Liu Tianzuo,, Zaza, Pan Youtong, Gao Dabo, Yang Dapeng and Ma Dianbin. It is a comedy love movie in which the hero and heroine meet each other when they are down and out, and the sparks of love are sparked in mutual healing. Laughter and tears are intertwined, which will make adults encounter family love difficulties, dreams and reality.

Jia Bing Liu Yan deducts the healing system, focusing on the fireworks in the street.

The movie "Bei Er Likes You" mainly tells the story of a talented chef Gong Bao (played by Jia Bing) and a rock-and-roll fan Quinn (played by Ada) who meet by chance and are also trapped in reality, and the healing love story from knowing each other to falling in love. The film dares to go against the trend, starting with a very life-like background and focusing on the love story between adults. Adult love is not so much a vigorous collision of passions as a search for resonance in dullness. Gong Bao and Fan Quinn met at each other’s most difficult moment. From the moment Gong Bao said "I decided to stay and help you", their fate was tightly tied together.

In addition, the film also starts from the little things that happen to ordinary people, and portrays everyone’s image in a three-dimensional and vivid way. A series of contrasting characters, such as the father (Yang Xinming), who is unwilling to be flexible and firmly committed to his wife, and the timid apprentice (Yu Yang), make the film closer to life and reality. Some media workers said after watching the movie that "the fireworks in the movie are very strong, just like the story that happened at our doorstep". Some people also wrote on social media: "No one is perfect, everyone in the movie has a selfish side, and it is precisely because of this that the protagonist in the story is like you and me in life, and the story is like happening around us."

　

Deeply analyzing the plight of adults, the story is full and resonates.

The film’s portrayal of the love between the man and the woman is not superficial, but also digs deep into the plight of adults, showing many social problems faced by adults and giving the film a deeper practical significance. Gong Bao (Jia Bing) is full of talents and dreams, but he can’t display them, so he has no choice but to hide in the deep alley; Van Queen (Ada) struggled for his dream for ten years, but it was hard to get anything, so he had to compromise with life. The two are unfortunate, and to others, living with them seems bleak; Fortunately, they met each other and supported each other to tide over the difficulties.

Another highlight of the film "Bei Er likes you" is that it expresses the hardship of life and the warmth of ordinary love in the form of comedy. Laughter and tears, relaxation, so that the audience can be cured after reading, and at the same time trigger thinking and resonance for life. A movie lover said after watching it: "Movies always make people laugh after crying and quarreling, as if to tell us that’ it doesn’t matter, the unpleasantness will always pass, and don’t forget to smile when it is difficult’". Another audience member said in an interview after watching the movie: "In the movie, Jia Bing confessed to Ada that he said’ Come with me, ok’, just because there was no flowery rhetoric, which set off the realism of the movie.". The pertinent evaluation has also aroused more people’s desire to watch movies, and they have expressed their desire to watch this healing film with their lovers.
