Many viewers have entered the cinema, recalling the epic history and remembering the revolutionary martyrs.

　 　 　 　The film Crossing the Yalu River is a "panoramic, epic" major revolutionary historical work that shows the War to Resist US Aggression and Aid Korea. The film material is basically taken from a TV series of the same name "Crossing the Yalu River" which premiered in the central government at the end of last year. Forty episodes of TV series were condensed into two and a half hours of movies, which were told for the first time from the perspective of Peng Dehuai, commander and political commissar of Chinese people’s Volunteer Army. From the strategic thinking of the central leadership, the battlefield strategy of the volunteers generals, the bloody battles of the frontline volunteers and other dimensions, the epic battles in the East-West Line and five battles were reproduced, and the magnificent history was fully restored.

　 　 　 　?

　 　 　 　"When the volunteer soldiers fought in the front, the dangers we encountered were unimaginable. I am very grateful to have such a work to restore this history, so that we can feel the ruthlessness of the war through movies, feel the selflessness and greatness of the revolutionary ancestors, and be immortal. China Volunteers, the most lovely person!" Walking out of the cinema, Ms. Li, an audience in Haikou, said emotionally.

Native tree species refers to the natural distribution of trees in this area or the long-term growth of local trees. National Forestry and Grassland Administration recently released that China actively adopts native tree species and grass species to carry out afforestation and greening. At present, all the artificial afforestation in China basically uses native tree species.

National artificial afforestation basically uses native tree species.

Since 2021, National Forestry and Grassland Administration has approved 47 improved varieties of forest trees, all of which are native species. At present, 670 indemnificatory nurseries have been built in China, focusing on cultivating fine varieties and strong seedlings of native broad-leaved tree species, shrub species and high-quality economic forest species, with an additional seedling production capacity of nearly 100 million plants, thus ensuring the demand for native tree seedlings for national greening.

In promoting the construction of forest cities, National Forestry and Grassland Administration requires that native tree species should be the main species, and the utilization rate of urban native tree species should reach more than 80%, so as to increase the application of native tree species and grass seeds in urban greening.

National Forestry and Grassland Administration has instructed 29 provinces to issue a list of main native tree species, and made clear the suitable areas and suitable greening types of native tree species, which provided a basis for popularizing the use of native tree species. The "Reference List of Major Cultivated Precious Tree Species (2022)" was issued to guide all localities to actively cultivate local precious tree species.

Wangkui, Heilongjiang: Native Tree Species in Urban Greening and Forestry Engineering "Playing the Leading Role"

Wangkui County, Suihua, Heilongjiang Province, is an important commodity grain base in China and a key area for the construction of the "Three North" shelter forest system project. The local area combines urban greening with key forestry projects, afforesting according to local conditions, and building ecological barriers with native tree species.

CCTV reporter Shi Yuyu:The tree species used in the "Three North" shelter forest in Wangkui County, Suihua City, Heilongjiang Province is the native tree species Larix gmelinii, which has the characteristics of evergreen all the year round and tall trees, and can provide effective shelter for the farmland next to it.

Entering Wangkui County, a series of "landscape green corridors" came into view. Since it was incorporated into the "Three North" shelter forest construction project system, according to the long, cold and dry climate characteristics of northeast winter, the local area mainly planted native tree species with cold resistance, drought resistance and easy growth, and the utilization rate reached over 90%.

Zhang Jingbing, director of afforestation station of Forestry and Grass Bureau of Wangkui County, Suihua City, Heilongjiang Province:In the past, there was no such shelter forest. Because the wind blew our corn down, this phenomenon was called "wind scraping the ground". Now, with the shelter forest, this "wind scraping the ground" phenomenon has been greatly reduced.

After years of "Three North" shelterbelt construction, the farmland shelterbelt area in Wangkui County has reached 4,900 hectares, effectively sheltering 135,000 hectares of farmland, accounting for more than 95% of the county’s farmland area.

Not only did the "Three North" project choose native tree species, but also Wangkui basically used native tree species in urban greening. With the goal of "the city is in the forest, the road is in the green, the building is in the garden, and the people are in the landscape", the local green garden projects such as Wangkui Botanical Garden have been implemented.

Wang Shuqi, Deputy Director of Wangkui Garden Construction Service Center, Suihua City, Heilongjiang Province:The Botanical Garden covers an area of 450,000 square meters, all of which are local varieties, including spruce and Pinus sylvestris var. mongolica. It adapts to the local climate and grows vigorously.

At present, the urban greening coverage rate in Wangkui County is 40.38%, ranking first in Pingyuan County of Heilongjiang Province.

Sun Chenggang, Deputy Director of Wangkui Garden Construction Service Center, Suihua City, Heilongjiang Province:In combination with the construction of the "Three North" shelterbelt project, we adhere to the principle of respecting nature and adapting trees in suitable places, giving priority to the selection of excellent native tree species, so that urban residents can feel real benefits.

Shijiazhuang, Hebei province: strengthening scientific research and cultivation to improve the quality level of native tree species

In Shijiazhuang, Hebei Province, the research and application of local native tree species have been strengthened, new tree species and new strains have been cultivated, and the quality level of local tree species has been continuously improved.

The recent high temperature weather in North China has made the Woods in the park a good place for many citizens to enjoy the cool.

Shijiazhuang citizen Li Xupeng:The park is also tree-lined. Even in a high temperature day of more than 30 degrees Celsius, you won’t feel particularly hot and sunburned if you come here for a walk and enjoy the cool.

Shijiazhuang citizen Qiao Jing:Because its flowers in spring are very beautiful, I was attracted by this flower, and then I looked it up and found it was called a neem tree.

The neem tree mentioned by the citizens is an ancient native tree species, which was recorded in Qi Min Yao Shu in the 6th century A.D. and widely distributed in northern China.

However, in the long-term growth and development process, problems such as single variety and loose wood have also appeared in neem. In order to fully explore the excellent characteristics of this ancient native tree species, foster strengths and avoid weaknesses, a "research team for the development and application of neem germplasm resources" was established in the local area.

Tian Guoying, Dean of Shijiazhuang Agricultural and Forestry Research Institute, Hebei Province:Together with China Academy of Forestry, Hebei Normal University and other scientific research units and universities, we formed a research team to excavate and utilize the native tree species Melia azedarach, and cultivated 8 new varieties and strains successively.

Nowadays, in Shijiazhuang, there are more than 20 native tree species such as Melia azedarach, which are widely used. These native tree species have strong adaptability and resistance to the local growth environment, especially to extreme low temperature or high temperature. At the same time, it is easy to plant and has a high survival rate, which can maximize its own characteristics and meet the greening effect.

Fangchenggang, Guangxi: Casuarina equisetifolia, the "guardian of the sea", greening the city and coast.

Fangchenggang, Guangxi, located at the southernmost tip of Chinese mainland coastline, is a typical coastal city with Beibu Gulf in the south. Usually, the wind and sand in coastal cities are relatively heavy, so greening should not only pay attention to beauty, but also consider wind and sand fixation. Casuarina is an excellent tree species with three characteristics. Let’s get to know it together.

On the sea side of the West Bay in Fangchenggang City, Guangxi, rows of Casuarina trees grow along the coastline, forming a shelterbelt and a unique urban landscape. Casuarina equisetifolia is an evergreen tree of Casuarina, which is salt-tolerant and sand-resistant. It is a pioneer tree species in coastal shelterbelts and is known as a loyal "guardian of the sea".

Zhong Yu, Head of Garden Department of Fangchenggang City Management Supervision Bureau, Guangxi:Because its root system is very developed, it has a very good protective effect on wind, and its leaves are very thin, and it is a scale leaf, so its demand for water is much smaller than that of other broad-leaved trees, so its wind-proof and sand-fixing ability is very good.

Not only that, Casuarina grows rapidly, with a height of 30 meters. Coupled with its beautiful tree shape, Casuarina is also used as a street tree and has a good performance in urban greening.

Su Xuepeng, Director of Nursery of Forest Seed Breeding Center in Fangchenggang City, Guangxi: Especially in our coastal city, if it is a seawall or a beach, this kind of Casuarina tree is really beautiful.

According to the data provided by the garden department of Fangchenggang City, at present, more than 60% of the urban greening trees in Fangchenggang City are native trees like Casuarina. Because of their strong adaptability and strong resistance to natural disasters, native tree species are gradually showing their value with the increase of dosage.

Zhong Yu, Head of Garden Department of Fangchenggang City Management Supervision Bureau, Guangxi:The salinity and alkalinity in the urban mudflats are very high, and it is very difficult to survive by planting other trees. However, if Casuarina equisetifolia is planted, it can effectively form a certain green barrier, which can effectively increase the green quantity of our coastal cities.

　　Recently, respiratory diseases have been high.

　　"Syncytial virus" topped the hot search list.

　　Some netizens asked questions.

　　"What is this?"

　　Syncytial virus is not a new respiratory disease.

　　Syncytial virus is not a new respiratory disease, and there was an anti-seasonal epidemic this summer.

　　Tang Zhichao, deputy director of the Department of Disease Control, Shunyi Women and Children Hospital, Beijing Children’s Hospital, said that respiratory syncytial virus is the most important virus pathogen that causes acute lower respiratory infection in children under 5 years old worldwide. Respiratory syncytial virus (RSV) infection is the primary cause of hospitalization of infants with viral respiratory infection, which seriously harms children’s health, especially premature infants and infants with congenital heart disease or primary immunodeficiency.

　　Children and adults can be infected.

　　Source: Yangguang. com

　　Syncytial virus is an RNA virus, which is transmitted by droplets and close contact, or by contaminated hands and objects. Patients often have upper respiratory symptoms after infection.

　　The incubation period of syncytial virus is usually 2-8.
Days, detoxification can last for 1-3 weeks. Early infection is mostly confined to the upper respiratory tract, showing symptoms of upper respiratory tract such as nasal congestion, runny nose, cough and hoarseness.

　　The typical symptoms of children infected with syncytial virus are fever, cough, stuffy nose and runny nose.

　　The typical symptoms of adult infection are very similar to the common cold, such as low-grade fever, cough, stuffy nose and runny nose.

　　Most patients’ symptoms will disappear spontaneously within 1-2 weeks, and a small number can develop into lower respiratory tract infection (i.e. bronchiolitis or pneumonia), which is more common in young infants. Clinical symptoms include cough and wheezing.

　　Gao Weiwei, chief physician of neonatal respiratory department of Guangdong Maternal and Child Health Hospital, said that syncytial virus is about 2.5 times as contagious as influenza.

　　At present, there are no syncytial virus vaccines and special therapeutic drugs on the market in China. Syncytial virus can be repeatedly infected and easily spread at home. In the absence of vaccines and effective drugs, measures such as strengthening personal protection should be taken to prevent infection.

　　The doctor reminds: Don’t overdo it and don’t "mix and match".

　　Recently, Xiao Zhao, a 16-year-old high school student, was admitted to the emergency intensive care unit for taking four kinds of cold medicines. Xiao Zhao found that she had symptoms of a cold and a little fever, so she took ibuprofen and crack at the same time. After taking the medicine, he felt that his symptoms were not obviously relieved, so he added two other cold medicines, which is equivalent to taking four cold medicines together.

　　Source: CCTV News

　　Gan Yongxiong, Chief Physician of Emergency Intensive Care Unit of Fangqiao Campus of the First Affiliated Hospital of Ningbo University: After being sent to the hospital, after our doctor’s judgment, we finally made it clear that it was acute renal failure and rhabdomyolysis, which was the effect of the superposition of these cold medicines on the kidneys.

　　The doctor reminded not to take too much medicine and not to "mix and match". Patients should pay attention to the drug instructions when taking drugs by themselves, and should not increase or decrease the types and doses of drugs at will. Even if you only take one drug, you can’t increase or decrease the dose at will. If multiple drugs need to be taken at the same time, it is best to consult a doctor in advance and take them according to the doctor’s advice. If you accidentally take too much medicine and cause discomfort, you should seek medical advice in time, inform the doctor in detail about the recent medication, and actively cooperate with the treatment.

　　In view of the recent increase in the number of outpatient and emergency departments in some places and the increase in the number of children infected with respiratory diseases, the responsible comrades of the National Health and Wellness Commission answered questions of concern to some people, especially the families of children, in an interview on November 23.

　　Q:

　　Recently, many local children’s specialized hospitals are overcrowded. What measures has National Health Commission taken to relieve them?

　　A:

　　Recently, we have continued to pay attention to the diagnosis and treatment of children susceptible to infectious diseases during the high incidence period, and guided all localities to strengthen overall planning and implement a graded diagnosis and treatment system.

　　Q:

　　Some community hospitals have recently set up inspection services for children, but some parents are worried that the lack of diagnosis and treatment capacity in community hospitals will delay their children’s illness. What should I do?

　　A:

　　National Health Commission has asked all localities to give full play to the role of medical associations, strengthen technical guidance to primary medical and health institutions, and improve the diagnosis and treatment ability of common infections and the efficiency of severe identification and referral.

　　Q:

　　Which hospitals are qualified to accept children with respiratory tract infection?

　　A:

　　National Health Commission has instructed all localities to publicize the information of medical institutions that can provide pediatric diagnosis and treatment services in the region, so as to facilitate the nearest medical treatment.

　　Q:

　　What should children do after they have a fever and cough?

　　A:

　　Large hospitals are crowded with people, waiting for a long time, and the risk of cross-infection is high. It is suggested that children with mild symptoms should first go to primary medical and health institutions and pediatrics of general hospitals. After seeing a doctor in a children’s specialist hospital, they can also be referred to primary medical institutions for follow-up treatment or home treatment through medical associations.

　　Q:

　　What conditions must the child go to the hospital for medical treatment?

　　A:

　　According to experts’ advice, children should take their children to see a doctor in time if they have ultra-high fever or persistent fever for more than three days, frequent cough affects their normal life, poor mental state or even drowsiness, increased respiratory rate or dyspnea, frequent vomiting, rash, headache or convulsions.

　　What do you think of when you mention sinkholes? Mysterious, dark, strange and exotic animals and plants. The discovery of the Hanzhong Tiankeng Group in Shaanxi, China in recent two years has attracted the attention of the world. Tiankeng Group has become another beautiful business card in Hanzhong after the Han culture of "Two Han and Three Kingdoms".

　　The discovery of the sinkholes in Hanzhong increased the number of sinkholes in China from 84 to 138, accounting for 39%, and increased the number of sinkholes discovered and confirmed in the world from 117 to 171, accounting for 31.6%, making it a well-deserved "first sinkhole group in the world". Jean Bottazzi, an internationally renowned cave explorer, praised the Shanjiayan Cave River Tiankeng in Ningqiang, Hanzhong as "the most beautiful Tiankeng in the world".

　　On March 13th, the academic seminar of Tiankeng Group in Hanzhong, Shaanxi Province, hosted by Shaanxi Geological Survey Institute, was held in Xi ‘an. Famous experts, scholars and government officials from home and abroad discuss practical issues such as the future development mode, protection and development strategy of Hanzhong Tiankeng Group, and plan the blueprint for the future road of Hanzhong Tiankeng Group.

　　The other side of the beauty of Hanzhong in Tiankeng Group

　　When it comes to Hanzhong, the mysterious, beautiful and unknown sinkholes will show another side of Hanzhong. Let the ancient Hanzhong be more aura and beautiful than the rigid and serious history.

　　What is a sinkhole? Luo Gan Zhou, director of Shaanxi Geological Survey Center, gave his own answer to this question in a relatively easy-to-understand language. Tiankeng refers to a geomorphological feature that the steep walls around it have a certain scale (generally more than 100 meters in depth and width) and develop in carbonate rock areas.

　　"It is inferred that the sinkholes in Hanzhong Tiankeng Group were formed 180,000 to 120,000 years ago, and the oldest can be traced back to 680,000 years ago. By studying the sinkholes, we can study the ancient geographical environment and climate, which can help us better understand the past. Unique terrain and special ecological environment under negative terrain are the best places for people to understand geological and climate changes. " Luo Ganzhou expressed the significance of tiankeng to the contemporary era.

　　Li Yichao, a senior engineer of Shaanxi Geological Survey Institute who has been engaged in tiankeng investigation for a long time, went deep into the bottom of tiankeng for exploration and research many times. Speaking of the exploration of the Tiankeng Group in Hanzhong, Li Yichao has endless stories. Interest and hardship coexist, and the tiankeng, which is rare on weekdays, is really charming but full of challenges.

　　"Most of the traffic in tiankeng is not very convenient. After getting off the bus, the team members have to carry more than 100 kilograms of equipment and food to walk for five or six hours. Generally speaking, we may walk for two minutes at most at a distance of more than 300 meters, but it will take more than an hour to go down the sinkhole. It takes more time to get up, it takes more than three hours to get up, and you can only get up and down with the help of lifting and rescue equipment. The degree of hardship can be imagined. Professional climbing gloves, our team members can wear out three pairs a month. It can be seen that this is difficult. The investigation is very hard, but our contribution is worth it. " Li Yichao said.

　　Luo Gan Zhou Xiang told Uncle Fang a little detail: "Once I went down the sinkhole, the road was very steep. I walked downhill for several hours, and my toenails were against my shoes. When I got back, I felt that my toenails were very painful and the color was a little black. A few days later, the toenail cover of my big toe fell off directly, which was particularly painful." Luo Ganzhou, who is over 50 years old, speaks lightly, but the dangers and pains may only be known to him.

　　Of course, the hardships are also full of fun. The light in the sinkhole is insufficient, and the darkness is beyond imagination. When two people sit face to face, they don’t move, and you may not feel anyone around you. But in the sinkhole, you can see transparent fish, meet all kinds of strange animals and plants, strange stalactites, and all kinds of strange geological structures and climate phenomena that are hard to see on weekdays.

　　Through many photos taken by investigators, it is not difficult to find that there are many spacious cave halls, mysterious and strange underground rivers, magnificent stalactites, stalagmites, edge stone dams and many other ingenious works from nature. For thousands of years, a unique primitive microclimate has been formed in the sinkhole, and the animal food chain and unique habitat in it are irreplaceable. In addition to these peculiar geological products, there are many animals and creatures, among which thousands of richness such as "Shafei Colored Grey Butterfly", "Blooming Pink Butterfly", "Elephant Cicada", "Green Scarab" and "Liliaceae Big Lily" were photographed by the respondents alone.

　　Flying cats are unique animals in Hanzhong Tiankeng. The flying cat’s scientific name is the flying squirrel, also known as "six unlike". It has a face like a fox, eyes like a cat, a rat with a pointed mouth, ears like a rabbit, paws like a duck, and a tail like a squirrel. Its wide fins between the front and rear legs can glide between cliffs and trees, with a maximum head and tail length of 1 meter and a weight of more than 7 kg. This kind of animal is very shy. It lies in the daytime and comes out at night. In addition, it is increasingly rare. It is not easy to see a living flying cat with one’s own eyes.

　　It is understood that the Hanzhong Tiankeng Group is the first tiankeng group with the highest latitude in the world discovered in the range of 32 ~ 33 north latitude. This discovery has important scientific value and fills the gap in the world karst geology research. There are 54 Tiankeng Groups in Hanzhong discovered this time, which are mainly distributed in Chanjiayan Town, ningqiang county, Hanzhong City, Xiaonanhai Town, Nanzheng County, Luojiaba Town, Xixiang County and Sanyuan Town, zhenba county. This discovery has increased the number of sinkholes in the world from 117 to 171, accounting for 1/3 of the global number of sinkholes, including 2 super sinkholes, 7 large sinkholes, 45 conventional sinkholes and 473 other geological relics.

　　Academician Yuan Daoxian of Chinese Academy of Sciences believes that the Hanzhong Tiankeng Group is located at latitude 32-mdash; — It was discovered for the first time in the range of 33 degrees, which made China moist in the tropics — The boundary of subtropical karst landform area has obviously moved northward, which has important scientific value. Reasonable protection, development and utilization of geological relics resources of Tiankeng Group will play an important role in promoting local economic development.

　　The important value of the discovery of the rare "Tiankeng Group" in Hanzhong lies in that it not only greatly enriches the tourism resources of geological relics in China and even the world, but also fills the blank of karst geology research in the world and increases the original samples of biological research. Through the study of its formation mechanism, conditions and evolution law, it will be of great scientific value to the study of paleogeographic environment and climate change in the north and south of China and even the whole world, and it will be praised by experts as a world-class "natural museum" that rewrites geological history.

　　Ambition to declare world geoparks and natural heritage

　　The geological park selected by UNESCO is a natural park with its geological scientific significance, exotic beauty and unique geological landscape, which integrates natural landscape and human landscape. The goal of UNESCO is to select more than 500 geological landscapes worthy of preservation and strengthen protection. At present, 35 geoparks in China have entered the UNESCO World Geopark Network List.

　　Whether it is a geopark or a world natural heritage, it is a leader in the global natural landscape, and its scientific significance and tourism appreciation significance are self-evident.

　　The reporter learned from different channels that at present, all parties are actively preparing for the world geopark and natural heritage declaration for the unique geological relic of Hanzhong Tiankeng Group.

　　The Hanzhong Municipal Government specially issued the Interim Measures for the Protection and Management of Geological Relics of Tiankeng Group in Hanzhong City, which made specific provisions on the scope of geological relics protection, regional management and protection measures, and legal responsibilities. Hanzhong will conscientiously do a good job in the protection of geological relics of Tiankeng Group in Hanzhong.

　　Hanzhong Municipal Bureau of Land and Resources said in a reply that Hanzhong will gradually promote the declaration of national and even world geoparks and natural heritage in due course.

　　It is understood that in October 2016, the Shaanxi Provincial Department of Land and Resources has awarded the provincial geological park construction qualification of Hanzhong Tiankeng Group; According to the provincial geological park planning to complete the construction task, Shaanxi Provincial Department of Land and Resources acceptance before the provincial geological park can be named. Provincial geoparks can only be declared as national geoparks after they are officially named for two years. Hanzhong will do a good job in basic work and declare national and even world-class geological parks and natural heritage according to relevant procedures.

　　Mao Xiaochang, a senior engineer of China Geological Survey, said in his speech that the formation mechanism of Hanzhong Tiankeng Group is different from that of South Tiankeng Group, and its biodiversity is also unique. Therefore, Hanzhong Tiankeng Group has the conditions to become a world-class in terms of rarity, scientificity, aesthetics and protection.

　　How to make good use of high-quality resources in developing and protecting economically underdeveloped areas

　　Tiankeng is a unique natural wonder, unique to karst conditions. In the natural landscape, it has a series of special tourism ornamental values and sensory attributes, such as rarity, strangeness, precipitousness, grandeur, beauty and unique ecological environment. At the same time, tiankeng always coexists with caves, underground rivers, strange peaks and rocks and other tourism resources, so it is undoubtedly a special super tourism resource.

　　It is understood that Chongqing Xiaozhai Tiankeng was opened to tourists in 1999, and Guangxi Leye Dashiwei Tiankeng Group is in the process of tourism development planning. In the future, the karst tiankeng scenic spot will add a bright spot to the world tourism industry.

　　How can Hanzhong miss such a good opportunity? In May, 2017, Hanzhong Municipal Bureau of Land and Resources and Hanzhong Municipal Bureau of Cultural Relics and Tourism jointly reported the topic to Hanzhong Municipal Government, suggesting that the world-class planning units should be selected, and in accordance with the principle of "development in protection and protection in development", Hanzhong Tiankeng Group’s geological relics protection and tourism development and utilization plan should be actively worked out, combining Tiankeng tourism with new formats such as culture, leisure, recreation, sports and research, and steadily promoting the geological relics protection and tourism development of Hanzhong Tiankeng Group.

　　Faced with such world-class tourism resources, it is reasonable for Hanzhong, which is economically underdeveloped, to have the impulse to develop and utilize it. However, tiankeng resources belong to non-renewable natural heritage resources, and once improperly developed, it will bring irreparable losses.

　　At the seminar, the reporter also heard different voices, but the voice of "protection first and moderate development" still dominated. For Hanzhong, where the economic strength is not strong and the pressure of getting rid of poverty is great, how to use the resources of Tiankeng Group to promote regional economic development and promote the local people to get rich and increase their income has become the main problem faced by the politicians.

　　The reporter had a detailed exchange with the deputy county (district) governors of zhenba county, Nanzheng District and ningqiang county. The conclusion is that everyone wants to use Tiankeng resources to promote the development of county economy, but this kind of utilization must be based on strict protection, and we should avoid rough development and homogeneous development of four counties, and start with high-end tourism and take a sustainable development path.

　　Zhou Qingfu, deputy county magistrate of zhenba county, told reporters that zhenba county will make rational use of Tiankeng, a high-quality resource, publicize Zhenba’s good ecological environment advantages on the basis of strict protection and reasonable planning, develop the Chinese herbal medicine industry around the high-quality ecological environment, and build Zhenba into a high-quality health care, pension, sports and experience base.

　　Wang Jun, the deputy head of Nanzheng District, also put forward his own views on the development of Hanzhong Tiankeng Group. Hanzhong Tiankeng Group should avoid large-scale development and give priority to protection. At present, it is difficult to develop Tiankeng with the ability of counties and districts, and it is easy to cause homogenization. Tiankeng is ecologically fragile and unrecoverable, and its safety is poor, so the development of Tiankeng should take the road of high-quality development.

　　Wang Longqing, chairman of Hanzhong CPPCC, believes that Tiankeng Group is the most precious, valuable and internationally influential resource discovered in Hanzhong so far. Establishing a research base for Tiankeng Group in Hanzhong is beneficial to the investigation, scientific management and development, geological monitoring and protection of Tiankeng Group in Hanzhong. Hanzhong City should take this opportunity, rely on the scientific research base as the platform, fully support the geological exploration work of the Provincial Geological Survey Institute, make overall consideration of the construction of the research base and geological museum, as well as security measures, attract world-class high-level talents to come to China for extensive exchanges, hire international professional teams to carry out development planning, and promote the scientific research and tourism development and utilization of Hanzhong Tiankeng resources in an orderly manner.

　　Mao Xiaochang, a senior engineer of China Geological Survey, also put forward his own views on the development of tiankeng. First, priority should be given to protection, and a high-end tiankeng adventure tour can be explored under the premise of protection. Tiankeng, a tourist resource, is not suitable for large-scale development. The location of the sinkhole should explore the mode of high-end in-depth tour, and professionals can be explored to explain professional geological and geographical knowledge to tourists, so that tourists can fully feel the unique charm of the sinkhole through five or six hours of in-depth tour. In addition, we can try to involve villagers in tourism, and develop some special projects such as geological and cultural villages and towns in the periphery to promote the development of local people.

　　Facing high-quality natural resources development and protection are not contradictory opposites. If we cling to the principle of protection and don’t make rational use of it, it will only be a good opportunity to delay development. If Jiuzhaigou clung to protection and didn’t seek development, it would be difficult to achieve such great achievements in local economic development today. However, development is not a kind of quick success and instant benefit, and it is a rational development path for the protection and local development of Tiankeng Group in Hanzhong to make long-term planning and rational utilization from the perspective of future generations’ long-term development. Presenting the most beautiful side of Hanzhong to the world may be the best protection for Hanzhong Tiankeng Group.

　　Researchers at the University of Colorado recently published the latest research results in the journal Nature Earth Science, pointing out that global warming will have a far-reaching impact on the distribution of wind energy resources around the world. By the middle and late part of this century, the available wind energy resources in the northern hemisphere will be greatly reduced, while the wind energy resources in some areas in the southern hemisphere may increase sharply, and the overall wind power development potential will shift to the south.

　　1. Distribution or transfer of wind energy resources to the southern hemisphere

　　The polar regions are cold and the equator is warm, and the westerly winds prevail all the year round in the mid-latitudes of the northern and southern hemispheres, which is also called thermal wind. In this wind belt, the average wind speed is greater than other places, and a large number of wind energy resources are gathered, covering many countries in the northern hemisphere, including China. Under the background of climate change, the change of mid-latitude westerly belt will directly affect the utilization potential of wind energy resources.

　　The latest research results of the University of Colorado in the United States believe that global warming will have a far-reaching impact on the distribution of wind energy resources around the world. By the middle and late part of this century, the available wind energy resources in the northern hemisphere will be greatly reduced, while the wind energy resources in some areas in the southern hemisphere may increase sharply.

　　Using the simulation results of supercomputer, the researchers discussed the evolution of wind energy resources in two different scenarios of greenhouse gas emission in the future. The first is a medium emission scenario, assuming that carbon emissions reach the highest in the middle of this century and then remain stable; By the end of this century, the concentration of carbon dioxide in the atmosphere is about 1.5 times of the current concentration, and the global average temperature is warming by 1.1 to 2.6 degrees Celsius. The second scenario is a high emission scenario, corresponding to the development mode of slow improvement of energy structure and lack of climate response measures, carbon emissions will continue to increase, the concentration of carbon dioxide in the atmosphere will exceed the current three times by the end of this century, and the global temperature will rise by 2.6 to 4.8 degrees Celsius.

　　The results show that the wind energy resources in the northern hemisphere will be significantly reduced in both moderate and high emission scenarios, especially in the mid-latitude areas including northwest China, Siberia, Northeast Asia, the United States, Canada, Britain and the Mediterranean coast, that is, along the westerly belt of the northern hemisphere. Under the high emission situation, by the end of this century, the wind energy resources from Inner Mongolia to Northeast China will even be reduced by 10% to 20%.

　　The wind energy resources in the southern hemisphere will not change much under the medium emission scenario, but will increase greatly under the high emission scenario. Especially in the high emission scenario, by the end of this century, the wind energy resources in eastern Brazil and northeastern Australia will increase rapidly by more than 40%.

　　2. The reason is that the warming ranges of the North and South poles are different.

　　This difference may be attributed to the fact that global warming affects the evolution of wind belts in the northern and southern hemispheres in different ways. In the northern hemisphere, arctic warming and sea ice melting are a positive feedback process that promotes each other, so that under the background of global warming, polar warming is more obvious; As a result, the temperature gradient between the equator and the polar regions is weakened, and the wind speed in the mid-latitude westerly belt is reduced as a whole. Some simulation results also point out that due to the significant warming at high latitudes, the cold-warm confrontation between the north and south sides of the mid-latitude region is weakened, and the activity of the storm system is reduced as a whole, which is also a reason for the decrease of wind energy resources.

　　In the southern hemisphere, especially in high emission scenarios, Antarctic warming is not as obvious as land warming in central South America, southern Africa and Australia. The temperature gradient between this part of the continent and the ocean at the same latitude increases, which becomes the dominant factor in the change of wind belt intensity. Land warming is faster, land thermal depression is enhanced, land-sea pressure gradient is increased, wind speed is increased, and wind energy resources are increased. Except Antarctica, the southern hemisphere continent is mainly distributed in tropical and subtropical regions, so the overall increase of wind energy resources is also most obvious in tropical and subtropical regions. It is worth mentioning that in the middle and high latitudes of South America and Australia, wind energy resources still tend to decrease, similar to the northern hemisphere.

　　3. The probability of extreme gale in northern Europe has increased.

　　The confrontation between the cold and warm air masses in the north and south is common in the westerly belt, which is also called the front. If there is a small disturbance in the atmosphere, for example, one side of the air mass moves to the other side actively, and the trajectory of the air mass deflects under the action of geostrophic deviatoric force, it will induce a large-scale atmospheric vortex, which is also called frontal cyclone. From the climate point of view, the area where frontal cyclones frequently occur and pass through is the area "located on the storm track", and the average wind speed is usually larger than other areas.

　　But if you want to use wind energy, the bigger the wind, the better. Extremely violent gusts will actually cause damage to windmills. The design of windmills is generally based on the criteria such as the maximum wind that can cope with a few years (for example, 50 years), which is directly related to the statistical data of local climate background.

　　Scientists use supercomputers to simulate northern Europe. The results show that if the global climate warms, the mid-latitude "storm track" will move northward as a whole, and the number of frontal cyclones will decrease, but the intensity of a single storm will increase. As a result, the frequency and intensity of extreme winds in northern Europe will increase. This is not good news for windmills designed according to past climate data standards, and it also means that new wind farms must consider the possibility of withstanding stronger storms in the future.

　　Corresponding to the extreme wind that may increase, the extreme waves at sea will also increase. The research on the future evolution of wind and waves in the North Atlantic shows that the current "once in 20 years" big waves may appear every 4 to 12 years in 2080; The climate simulation of the North Sea in Europe shows that by the end of the 21st century, the average height of waves will rise by 5% to 8%. Because of the limited land space and greater friction resistance, offshore wind power generation is the hot direction of current development; The double test of wind and waves poses a new challenge to the construction of offshore wind farms in mid-latitude areas. However, in areas with lower latitudes, such as the Mediterranean coast, because the storm track moves northward, the wind and waves in the future climate outlook will be reduced.

　　4. Warming is a double-edged sword for high latitudes.

　　In high latitudes or arctic regions, cold weather is one of the reasons that hinder the popularization and application of wind power generation. Windmill blades are exposed to humid air with sub-zero temperature, and once they are frozen, the blades will lose their balance, the resistance will increase, the efficiency of wind power conversion will be reduced, and there are potential safety hazards. According to statistics, in Finland, 9%-45% of windmill stalling events are related to icing. Of course, the problem of icing can be overcome to some extent by designing blades that are not easy to gather ice and snow and using current heating, but it will also make the cost of operation and maintenance higher.

　　Climate warming may be good news for these areas. Supercomputer simulation results show that at the end of this century, the frost period in high latitudes will be obviously shortened and the frequency of icing will be greatly reduced, regardless of the assumed temperature rise. In some parts of Scandinavia, the icing frequency will even drop by 100%. At the same time, because the storm track moves northward, the high latitude zone will be more frequently affected by the frontal cyclone system, and the potential wind energy resources will become more abundant. As a result, some areas that are not suitable for the layout of wind farms may become new territories for opening up wind energy resources in the future.

　　Corresponding to the temperature rise, the permafrost zone in high latitudes will be reduced, which will bring both advantages and disadvantages. First, because the scope and depth of frozen soil layer are reduced, it will be more convenient to lay transmission lines and build wind farms. Secondly, if the frozen soil layer continues to melt, how to design the windmill base becomes a problem, because the stress and support relationship between the windmill and the soil will continue to change, and there will be the risk of lodging if it is slightly unbalanced. How to weigh the gains and losses, reduce risks and expand benefits depends on the wisdom of engineers.

　　Not only for onshore wind farms, but also for offshore wind farms in high latitudes, especially for the region with the fastest growing number of offshore wind farms — — For Europe. The study of future sea ice evolution shows that the number of days covered by sea ice in the North Baltic Sea and the Gulf of Bosnia will be reduced from the current 130-170 days to 0-90 days in the later part of this century, and many areas will not even be frozen all year round. However, the decrease of sea ice will make the foundation stability of offshore windmills worse, and it is more vulnerable to the damage of strong winds and waves. At the same time, rising sea level will also increase the risk that the windmill base will be flooded. However, the melting of glaciers will reduce the salinity of seawater, which will help to slow down the corrosion of seawater to the windmill base and transmission line materials.

　　Extended reading

　　The potential of wind farms such as Jiuquan may decline.

　　At present, the world’s largest wind power base is located in Jiuquan, Gansu, China. By 2012, the installed capacity of wind power has exceeded 6,000 megawatts, which is equivalent to supplying the electricity demand of the whole UK, and this figure is still rising. Gansu is located in the wind energy-rich zone in northwest China-Mongolia, with high wind speed all year round and wind energy density exceeding 150 watts per square meter. It is an ideal place for China to build wind power plants, and it has also played an important role in promoting local employment, taxation and economic development. If the climate warming continues, the potential of wind power in this region is likely to decline, and the potential of existing wind power equipment cannot be fully exerted. Many countries in the mid-latitude zone of the northern hemisphere, including China and the United States, will face the same problems, which will also add more pressure to the realization of human energy conservation and emission reduction goals.

　　The researchers pointed out that the current assessment and layout of wind power generation capacity are mostly based on past climate data statistics, but rarely consider the impact on the distribution of wind energy resources after the future atmospheric circulation changes due to human activities. The new research provides a new reference for the economy and sustainability of wind power plant layout in the future, and for decision makers to measure and plan alternative energy strategies.

Recently, one of Qian Aunt’s franchisees, the "Third Sister", broke the news on the Internet, saying that she had been losing money since she joined two Qian Aunt’s houses with an investment of 1.7 million yuan, and she was forced to close the store out of stock, so she had no choice but to speak online to defend her rights and accuse Qian Aunt of unreasonable joining policies and management problems, which caused widespread concern.

△ The Tik Tok account of "Silly Third Sister" is now "no such person"

In fact, this franchisee’s experience is not a case. On Baidu Post Bar, Tik Tok and other platforms, there are a lot of franchisees’ information about Aunt Qian.

Some people say that the store has been losing money since joining Qian Aunt, and the investment has reached 800,000 yuan. There are also franchisees who broke the news that they joined Qian Aunt, and they lost more than 200,000 yuan in two months of opening. Together with the previous investment, the overall loss has exceeded 700,000 yuan. At present, the store is in the process of transfer.

On platforms such as 58 City, you can also see a lot of transfer information about Aunt Qian. Some franchisees said that there were few transfers before last year, and some were internal transfers, but this situation has changed this year.

What happened to Qian Aunt, a star company that was robbed by capital and is expected to be listed on Hong Kong stocks this year?

Before answering this question, let’s take a look at how it started.

one

How did Aunt Qian get started?

Nine years ago, the founder of Qian Aunt opened a pork shop in a vegetable market in Dongguan. Because it advertised "No overnight meat", it affected other people’s business and was driven out of the vegetable market.

When Aunt Qian got off to a bad start in Dongguan, she moved to Shenzhen. In 2013, the first Qian Aunt in Shenzhen opened in Futian, and the slogan "Don’t sell overnight meat" quickly attracted the attention of local people. Since then, Aunt Qian has quickly opened more than 1,500 stores in Guangdong.

The rapid development of Aunt Qian has naturally attracted the attention of capital. During 2015-2019, Aunt Qian received five rounds of investment, including many star investment institutions. The latest financing took place in December last year, when Aunt Qian’s valuation reached 8.5 billion to 10 billion yuan.

△ Figure from the network

Driven by capital, Aunt Qian started a journey of crazy expansion. In November 2020, Aunt Qian entered Zhengzhou; In December 2020, he entered Beijing; In January 2021, she entered Tianjin, Fuzhou and other places: Aunt Qian is gradually moving from the region to the whole country.

According to official data, from July 2020 to February 2021, in seven months, the number of Qian Aunt’s stores expanded from 2,000 to 3,000, with an average of 142 stores opened every month.

Of course, the rapid expansion of Aunt Qian mainly depends on franchisees, and the proportion of its franchisees is close to 90%. Under the joining mode, Aunt Qian only needs to build a good supply chain, build a good model store and do a good job in attracting investment, so she can open a store quickly.

So, how much does it cost to join a money aunt?

2

How much does it cost to join Aunt Qian?

First of all, before opening a store, you need to pay the initial fee, deposit, decoration fee and so on. Each store has an initial fee of 30,000 yuan and a deposit of 40,000 yuan; The decoration fee is 200,000 to 300,000 yuan-some franchisees questioned that Aunt Qian’s decoration fee is too high, far exceeding the market price, which means that she wants to earn the franchisee’s money through the decoration fee.

Secondly, in order to ensure the passenger flow, Aunt Qian generally requires franchisees to find stores in prime locations, and the transfer fee of such stores is often as high as 100,000 yuan. Calculated, if a franchise store wants to open, the above expenses alone will reach 500,000 yuan.

Besides, to recruit a store manager, a division division and a shop assistant, franchisees need to pay Qian Dama a "service delivery fee" ranging from 6,000 yuan to 4,000 yuan and 800 yuan, and the wages of these people are calculated separately.

In this way, if you want to open a money aunt, you must have at least 550,000 yuan, which is obviously not a small number.

So, do you think you can make money by opening a business? Not really! And on the contrary, opening a business means paying more money!

Why did Qian Aunt’s franchisees lose blood?

After the store is opened, there will be a continuous brand use fee. For the income generated by franchisees before 19:00 every day, Aunt Qian should draw 1.5% of the turnover as the brand use fee.

For newly joined stores, three months before the opening of the store is the drainage stage, and Aunt Qian requires that the goods cannot be increased in price, but can only be "flat in and flat out". After the drainage, the price can only be raised after the sales amount reaches the standard set by the company, and the price increase is also strict.

Therefore, the phenomenon that money aunt is in the market is basically what franchisees throw out with real money every day. Moreover, such regulations have also caused a phenomenon: the more franchisees order after opening, the higher the cost, the more losses, and the faster franchisees may "die".

After the price can be raised, franchisees will face a very realistic problem: many people who buy meat and vegetables are aunts and grandmothers, who are very sensitive to the price. After the price is raised, they would rather go a little further to buy cheaper ones, resulting in a decrease in the passenger flow of Qian Aunt’s store, which in turn reduces the income.

△ Figure from the network

In addition, franchisees will also face increasing "involution".

There have been media reports that at the end of 2017, Aunt Qian has shortened the minimum distance of the store from 300 meters to 250 meters. In this way, the store density of Aunt Qian has increased, and the brand has started, but the regional protection has also weakened, the competition of franchisees has also intensified, and the profitability has naturally declined.

According to Qian Aunt’s franchisee, in the past, Qian Aunt asked for at least 1,500 households to choose a community, but now many communities can open stores as long as four or five hundred households. This kind of traffic simply cannot support the normal operation of a store. What’s more exaggerated is that two money aunts have been opened in many communities, and the internal competition is fierce, which has aroused the dissatisfaction of franchisees.

According to analysis, the reason why Aunt Qian wants to open stores intensively (for example, in Guangdong, the base camp, there are nearly 1,000 stores in Shenzhen and Guangzhou alone) is because of financial pressure to rush to the market; The more stores it opens, the more it earns under the condition of ensuring a certain net interest rate, but it just passes on the costs and sacrifices to franchisees.

Therefore, for Qian Aunt’s franchisees, the investment of 550,000 yuan to open a store is only the beginning, and the continuous loss is the normal state of many franchisees.

Franchisees are dissatisfied with Aunt Qian and these six points.

According to the Dining Book, in addition to the above, franchisees are mainly dissatisfied with Aunt Qian in the following aspects:

First, there are too many "must-haves". Aunt Qian has certain products in every store. These "certain products" are unified in the whole region, but the problem is that there are a large number of "certain products", and some "certain products" are not hot-selling goods. Many stores simply can’t sell them out, and the products that can’t be sold out will be discounted, which will eventually cause losses for the stores. Take beef as an example. Some franchisees said that Aunt Qian’s beef is not a hot commodity, and his daily loss in beef is as high as that in 200 yuan.

Aunt Qian has requirements for suppliers and the amount of goods they buy every day, and they can’t be returned after 12 noon. In this case, if you are not sure about the purchase quantity, it will easily lead to inventory, and the inventory will be discounted, and a discount will consume profits.

Second, the purchase price is too high. It is understood that Qian Aunt earns the most money from pork, but its pork price is about 20% higher than the normal price of foreign mining. In addition, Qian Aunt’s dishes in many places are purchased from nearby vegetable markets and then sold to franchisees at a higher price, which makes many franchisees unbearable.

Third, the fine is unreasonable. First, according to the regulations, franchisees can only purchase goods from headquarters. Once they are found to purchase goods from outside, they will be fined 20,000 yuan. Second, Aunt Qian has strict regulations on the goods that can’t be sold out, and she can’t sell them overnight, not even eggs. The franchisee "Sanjie" at the beginning of the article, her employee was fined once for selling eggs overnight.

Interestingly, after the "Three Sisters" exposed Qian Aunt on the Internet, Qian Aunt’s South China area adjusted the fine amount the next day, and the fine amount directly dropped from 20,000 to 10,000 yuan.

Fourth, increase the amount privately. According to the franchisees, many stores of Aunt Qian have been "privately added", and no matter whether the store wants it or not, it will be added to the store privately. During the Dragon Boat Festival, many stores suffered great losses because of selling zongzi. Some stores bought two zongzi, but when they received the goods, they received more than 20 pieces, which could not be sold at all.

Fifth, order less. It is understood that the daily order quantity of the store is between 300 and 400 pieces. After being delivered to the store, the franchisee can’t check them one by one at the first time, which will cause losses. For example, four watermelons were ordered, but only three were actually delivered. This kind of scene is more common, and it also gives many franchisees a headache.

Sixth, internal corruption. According to a franchisee in Shenzhen, Qian Aunt’s shop was recommended by the company, and the price was also negotiated by the company. Finally, the rental price for the franchisee was 28,400 yuan/month, and later the franchisee directly negotiated with the landlord for 20,000 yuan/month (the price to be transferred). Because the rent of the store was raised, Aunt Qian’s development department also charged a "tea fee" of 14,000 yuan, and the franchisee had to pay the company a "site selection fee". The practice of "eating at both ends" in the development department makes franchisees very speechless.

There is not much time left for aunt Qian.

In the final analysis, the reason why franchisees don’t make money is due to the blind expansion of Aunt Qian. Its supply chain in many places is not perfect, and the cost for franchisees is too high.

Guangdong is Qian Aunt’s base camp, and there are enough stores here to form a scale effect, so that Qian Aunt has bargaining power on the upstream, which can reduce costs and leave profit space for franchisees. But in other places, this model has encountered challenges.

Aunt Qian’s crazy expansion in the country seems to be a lot, but on average, in every city, the number is not much. In this case, the bargaining power is limited when purchasing from local suppliers, and the cost cannot be suppressed. The cost can’t be suppressed, but to ensure its own profit space, it can only be passed on to franchisees.

Of course, in the base camp of Guangdong, Aunt Qian is not completely "safe". According to franchisees, many stores in Guangzhou and Shenzhen have closed this year. In the 58 cities of Guangzhou and Shenzhen, you can also see a lot of information about the transfer of Aunt Qian-the crazy expansion of Aunt Qian has begun to have an impact on her base camp.

Aunt Qian made money and gained the reputation of consumers, but many franchisees suffered miserably. This is a model that violates the basic laws of business. This irrational, inconsistent interests and unable to achieve a win-win model is doomed to be unsustainable.

All the rapid expansion is based on the premise of profit. If Aunt Qian expands crazily for listing, but regardless of whether the franchisees are profitable, there will be big problems. This kind of expansion is "stepping on the body of the franchisee", so even if it can finally go public, it is also a bloody listing.

It is reported that at present, there are franchisees who are preparing to go through legal procedures and file a lawsuit with Aunt Qian.

The time left for aunt Qian may really be running out.

　　In recent years, with the description of real life and the restoration of hot spots of the times, realistic works often detonate social topics and enjoy high ratings. Among them, the industry drama that reveals the inside story of the industry and tells the story of the workplace is a hot topic, covering many types of industries such as finance, lawyers, real estate, brokerage and public relations, but it is still a minority that can truly present the industry ecology and break through the expression boundary. Recently, the public relations industry drama "Emergency Public Relations", which was broadcasted on CCTV-8 and Youku platform, achieved a breakthrough.

　　As the saying goes, "amateurs watch the excitement and experts watch the doorway". From the perspective of watching the excitement, the work with gorgeous appearance and rich content is often the type targeted by industry drama creators, and public relations is one of them. Public relations, in the public’s cognition, is often well-dressed, complicated, powerful and mysterious. Public relations industry dramas seize the public’s curiosity, often start with hot events that focus on disputes and multi-party games, create story scenes with strong conflicts and strong dramatic reactions, and devote themselves to showing the decisive strength and resolute action of public relations people, thus mobilizing the audience’s enthusiasm for watching. For example, last year’s hit public relations industry drama "Perfect Relationship" started with the star derailment event that netizens are most keen on watching, showing how public relations people can help artists avoid being tracked by reporters in a short time, give the best plan, coordinate the relationship among the three, and finally calm down the whole process of public opinion crisis. The whole process is both exciting and realistic, and it is very enjoyable to watch. However, after watching it, how to dig deep into the industry and show the doorways of the workplace is often overlooked, which is why domestic industry dramas are often criticized for being vain and ungrounded.

　　Domestic public relations industry, as a new industry with the development of China’s modern economy, has gone through 40 years of initial and development before it came out of the misunderstanding of colored glasses. Behind it, countless public relations people fought day and night to vindicate it. The efforts and struggles behind them, their ordinary and greatness need to be presented more in public relations dramas, and there are more stories to be seen in this industry. Taking the story of crisis public relations expert Lin Zhongshuo as an incision, Emergency Public Relations tells the hardships behind his game with all parties and the resolution of the crisis, showing the ideal light of "Lin Zhongshuo" sticking to purity and justice and keeping the pulse at the bottom line, and opening up a new height of public relations type TV drama creation.

　　First, the integration of small details and big events makes the story more credible. Good details are the nectar of the story, which can expand the connotation of the story. Emergency Public Relations mostly involves big brands and big events, but in creation, it pays great attention to the control of details, thus reducing the sense of distance and strangeness between the public relations industry and the public and making it more sensible. For example, in the second case of the play, a middle-aged man who was under the pressure of supporting his family died of cancer, and the fact that he had been overworked under the wolf culture for a long time was also exposed, but he was dismissed because he could not meet the KPI requirements. Subsequently, an article by WeChat official account, Anxiety of the Quasi-Middle Class, triggered further fermentation of public opinion, and the content of this article, for example, caused a sensation in reality many times, which made the audience feel strongly substituted. Many netizens even discussed hot topics such as 996, 007 and middle-aged unemployment in the barrage area, just like the debate scene. There are many details like this. For example, every time a crisis occurs, netizens who seem to copy Weibo’s comments comment on the scene, such as various workplace concerns. Lin Zhongshuo joined the company as an airborne leader, and his colleagues who were forced to transfer to other departments were dissatisfied. Some colleagues clamored that they would rather leave their jobs than enter the new department, while savvy colleagues said: We are just surprised. Come and find out the situation. Others are making trouble, which has nothing to do with us. Netizens commented, "It’s too real. Who installed a camera in our company?" These vivid details pave the way for the conflict trend of every major event, which makes the play have a real sense of modern workplace.Characters are also more representative.

　　Second, individuals and groups reflect each other, showing the complex humanity behind multiple games. Public relations, also known as public relations, also means that it involves both individuals and the public as a whole, and is closely related to everyone in society. How to show the complexity of human nature behind it is the key to the deep development of the play. As a crisis public relations agent, Lin Zhongshuo should safeguard the interests of customers, but at the same time he also insists on justice in his heart. As a media person who upholds justice, Xu Wenwen also needs to consider that one of her articles may become a knife that hurts people. Lawyer Yuan Wei often has conflicts between truth and jurisprudence. The public, too, was able to avenge the victims in anger yesterday, but it may also change its direction in tomorrow’s changing information and become the perpetrators of cyber violence. "Emergency Public Relations" presents the struggles and thoughts of different individuals and groups in one case after another, and also makes the off-screen audience further reflect on themselves, how to make their own choices and whether their ideas are objective enough before complicated situations. For example, the third case of the play. The case revolves around the sexual assault of a guest in Diyun Hotel by a waiter. Through investigation, Lin Zhongshuo found that behind it was a "rape performance" made by his competitor Fang Li and Yizhuang Hotel. His assistant tracked down the actress in this incident. The actress was upset because of the public opinion of the incident and thought of her ideal decision to be an actor. However, the actor in this incident would rather admit sexual assault than confess because the other party paid off his gambling debts.Considering that the incident has no room for change, in order to calm the crisis as soon as possible, Lin Zhongshuo and Diyun Hotel can only choose to bear the consequences of the incident, and the relevant responsible persons voluntarily resign and strengthen further rectification. Among them, the incident is not without a chance to make a comeback. Xu Wenwen wanted to reverse public opinion through interviews with actresses, but she chose to give up considering that the fate of an actress was ruined. Lin Zhongshuo’s assistant found evidence that Fang Li and Yizhuang Hotel joined forces, but this incident would affect her good friend’s ability to stand in the industry from now on, and Lin Zhongshuo also gave up. In this incident, human nature is facing many tests, and finally it can only seek a compromise balance. The proposition left to the public is that if public opinion is more rational, there may be better choices. "This drama is a panoramic observation of social events from the perspective of crisis public relations industry, such as domestic violence, hotel safety accidents, lack of emotional education, cyber violence, etc., which is more or less connected with the social hotspots I usually pay attention to. We hope to guide the audience to look at and discuss these hot events rationally, get some insights, and make some changes in action. "As Huang Xiaoming said in an interview, changes in groups will give individuals more possibilities.

　　Third, the industry is related to industry values, and the ideals and beliefs of the workplace are tapped. The significance of the existence of industry drama is not limited to telling some dramatic stories, but should show the values and professional ideals that the industry should have and give everyone who works hard in ordinary posts a sense of identity. This is the energy that industry drama should have. This is also the reason why "Emergency Public Relations" is different from ordinary public relations dramas. The whole drama has always been committed to the transmission of industry values. At the beginning, the play put forward the meaning of public relations. "What’s the point of public relations if it only considers the interests of customers and doesn’t consider the public interests?" In the first incident, international airlines ignored the rights and interests of customers and blindly pursued interests. Facing this incident, reporter Xu Wenwen mentioned the issue of values in a conversation with Lin Zhongshuo. If everyone ignored the positive values for the benefit, what would the world be like? In the end, due to the high profile and interest-oriented values of international aviation, Lin Zhongshuo gave up this customer, and also guided Xu Wenwen to attack international aviation from the perspective of monopoly, and finally made it withdraw from the Asia-Pacific market. In the second case, the corporate wolf culture was criticized for overemploying people. General manager Hua made no apologies for the dismissal of middle-aged employees, and even accused the employees’ families of extortion after their death from cancer, which made public opinion stunned. Lin Zhongshuo tried his best after the notice of termination was issued by General Manager Hua, and finally persuaded him to withdraw the charges against his family members by showing General Manager Hua that it was not easy for middle-aged employees to take care of their relatives.All this has long gone beyond the scope of public relations, but this is the humanistic care that public relations people should have. As the opposite of the drama’s values, Fang Li has dealt a fatal blow to many enterprises through unfair competition by unscrupulous means for profit, but he has sold clients’ stocks through securities lending and illegally made profits. Therefore, both his father-in-law and his former boss look down on him. His existence highlights the value of people like Lin Zhongshuo, and further emphasizes the importance of a sense of justice and responsibility in the workplace. I believe that with the development of the plot, he will also be reviled.

　　360 lines, all lines are wonderful. I believe that with the breaking of high-quality industry dramas such as Emergency Public Relations, more creators will be awed by the creation of industry dramas, respect the ordinary persistence of everyone in the workplace, show every effort behind success, and light a beam of light for those who are struggling silently.

　　Cctv news(Reporter Xu Hui) Recently, a netizen in Gaoyi County, Shijiazhuang City, Hebei Province released a video, saying that the yield of 280 mu of wheat he planted was reduced or even completely lost, which was suspected to be related to the use of pesticides by a company before planting sweet potatoes. According to "Gaoyi released" WeChat WeChat official account news, on June 3, Gaoyi County Agriculture and Rural Bureau released "Gaoyi County’s information bulletin about" a company planted sweet potatoes in Gaoyi, causing no wheat harvest ".

　　According to the report, on May 29, a video of "A company planted sweet potatoes in Gaochun, causing no wheat harvest" was spread on the Internet. The Gaoyi county government attached great importance to this and instructed the county agricultural and rural bureau to invite experts from the agricultural industry in Hebei Province to form an expert group to conduct investigation and verification quickly. The survey results are hereby notified as follows:

　　1. According to the field survey, among the 1,500 mu of wheat, 1,240 mu is growing normally, and 260 mu is growing poorly, among which 100 mu is dwarfed and dotted without ears. According to the yield analysis of the plots with poor growth by the expert group, the area with dwarf plants and no spikes in patches is 194.74kg/ mu, while the other areas are 326.46 kg/ mu. Reasons for low yield: in some areas, the sand layer below 45cm is the whole body, which leaks water and fertilizer, and the ability of water and fertilizer conservation is poor; Extensive field management and insufficient water and fertilizer supply; The measured plot plants are dwarfed, and their growth is inhibited.

　　2. Samples were taken from the wheat with poor growth and the dried sweet potatoes stored in farmers’ homes, and Hebei Taistin Testing Technology Service Co., Ltd. was entrusted to detect pesticide residues. The results showed that all the samples submitted met the requirements of GB2763-2019 "Maximum Residue Limits of Pesticides in Food".

　　3. After visiting and investigating villagers and sheep farmers nearby, no sheep died or had any adverse reactions after eating sweet potato leaves, and the village committee did not receive any relevant reports.

　　4. The soil pesticide residues in plots with obvious dwarfing and growth inhibition have been sampled by the Agricultural Products Quality and Safety Supervision Bureau of Hebei Provincial Department of Agriculture and Rural Affairs, and are being tested, and the results will be announced to the public in time.
