Soda soda, as an important raw material in chemical industry, its price fluctuation has a far-reaching impact on the whole industrial chain. In recent years, the price of soda ash has been continuously depressed, which has aroused widespread concern in the market. This paper will deeply discuss the reasons why the price of soda ash is difficult to increase, and put forward the corresponding solutions.

First, the reasons for the low price of soda ash

1. Imbalance between supply and demandThe relationship between supply and demand in soda ash market is the core factor affecting the price. In recent years, with the continuous production of new capacity, the supply of soda ash has increased significantly, while the demand growth is relatively slow, resulting in oversupply in the market.

2. Cost pressureThe production cost of soda ash mainly includes raw materials, energy and labor costs. Although the prices of some raw materials have increased, the overall cost pressure has not increased significantly, making it difficult to support the upward trend of soda ash prices.

3. Substitute competitionWith the development of technology, some new materials have gradually replaced some application fields of soda ash. For example, some processes in the glass industry have begun to use other chemicals to replace soda ash, which further reduces the market demand for soda ash.

4. International market influenceThe price fluctuation in the international soda ash market will also have an impact on the domestic market. In recent years, the international price of soda ash has been in the doldrums, and the low price impact of imported soda ash makes it difficult to raise the domestic market price.

Second, the strategy to solve the low price of soda ash

1. Optimize the production capacity structureBy eliminating backward production capacity, optimizing the existing production capacity structure and reducing the pressure of oversupply in the market. The government and enterprises should strengthen cooperation, promote industry integration and enhance overall competitiveness.

2. Enhance the added value of productsEnterprises should increase R&D investment, develop high value-added soda ash products and expand new application fields, such as environmental protection and new energy, so as to enhance the market competitiveness of products.

3. Strengthen international cooperationThrough in-depth cooperation with the international market, we will expand export channels and ease the pressure of supply and demand in the domestic market. At the same time, enterprises should actively participate in international market competition and enhance brand influence.

4. policy supportThe government should issue relevant policies to support the healthy development of soda ash industry. For example, through tax incentives, subsidies and other means, reduce the cost of enterprises and enhance market competitiveness.

Third, the soda ash market supply and demand situation analysis

As can be seen from the above table, in recent years, the difference between supply and demand in the soda ash market has widened year by year, and the problem of oversupply has become increasingly serious. This directly led to the continuous low price of soda ash.

Fourth, the future outlook

Facing the grim situation of soda ash market, enterprises should actively respond to it, and make efforts in various aspects such as technological innovation, market expansion and policy support to enhance market competitiveness and promote the reasonable recovery of soda ash prices. At the same time, the government and industry associations should also strengthen guidance to promote the healthy development of the industry and ensure the long-term stability of the soda ash market.

Since the conditional listing of the first Covid-19 vaccine in China at the end of December 2020, the relevant state departments have carried out vaccination work nationwide. Among them, the vaccination work in Covid-19, a key population, is progressing in an orderly manner.

What is the current progress of vaccination in Covid-19? Why should we cover more people? Is the safety of the vaccine guaranteed? What should I do if there is an adverse reaction? With these questions, the reporter interviewed relevant experts.

What’s the vaccination situation?

-A number of vaccines have been conditionally marketed, and 74.956 million doses have been inoculated.

After the outbreak of COVID-19, China quickly deployed a number of technical routes to develop vaccines. At present, five vaccines have been approved for conditional marketing or emergency use, including three inactivated vaccines, one adenovirus vector vaccine and one recombinant protein vaccine. Vaccination is promoted in order according to key groups, high-risk groups and other groups.

According to the data of the National Health and Wellness Commission, as of March 14th, 64.98 million people have been vaccinated with Covid-19 vaccine all over the country. As of 24: 00 on March 20, the cumulative report of vaccination has reached 74.956 million doses. In less than a week, nearly 10 million people were newly vaccinated.

Wang Junzhi, an academician of China Academy of Engineering, said that the composition of inactivated vaccine is the closest to the natural virus structure, which is relatively stable, convenient to transport, and usually has a strong immune response. Generally, two injections are used for immunization, which has good safety.

The preparation process of adenovirus vector vaccine is relatively simple and the cost is relatively low. It is successfully developed on the basis of the original Ebola vaccine of adenovirus type 5 in China. The vaccine can not only effectively induce neutralizing antibodies, but also enhance cellular immunity. The adopted immunization program is one-shot immunization, which is very convenient for emergency use of some special people.

Recombination vaccines expressed and purified pathogen antigen protein in engineering cells by genetic engineering, and then prepared into vaccine. Different from adenovirus vector vaccine and inactivated vaccine, it is a Covid-19 vaccine developed by a new technical route with high safety.

Experts said that Covid-19 vaccine in China has high accessibility and safety, and all citizens who are willing to vaccinate can vaccinate. Under the premise that the safety of domestic vaccines is guaranteed, the public is advised to actively vaccinate domestic vaccines and establish their own immunity and protection.

Why should we cover more people as soon as possible?

-China’s vaccination rate is still relatively low, and vaccination should be further accelerated to form an immune barrier.

After the outbreak of the epidemic in COVID-19, China has taken decisive and powerful prevention and control measures, successfully curbed the further spread of the epidemic, and achieved significant strategic results in epidemic prevention and control.

"From the perspective of the whole world, all major countries regard vaccination as an effective means to finally overcome the epidemic, and they are all promoting vaccination in an all-round way." Mao Junfeng, deputy director of the Consumer Goods Industry Department of the Ministry of Industry and Information Technology, said.

Feng Zijian, deputy director of China CDC, pointed out that the epidemic situation in the world is still prevalent, but the vaccination rate in China is still relatively low, which is far from a high level of population immune protection. The entry of people or goods from high epidemic areas still has the risk of spreading in China, so vaccination should be further accelerated to form an immune barrier.

Feng Zijian stressed that even people who have been infected or vaccinated in high-prevalence countries cannot completely avoid infection. "Although the risk of illness will be greatly reduced, there is still a risk of reinfection. If it is not well guarded after entry, it may also lead to spread in China. "

He Qinghua, the first-class inspector of the CDC of the National Health and Wellness Commission, pointed out that because the epidemic situation in China has been effectively controlled, many people mistakenly believe that the epidemic situation is far away from themselves and the urgency of vaccination is not too strong. He Qinghua appealed that the COVID-19 epidemic is still prevalent all over the world, and no one can be immune to it. Vaccination is the most effective means to prevent and control the COVID-19 epidemic.

How to ensure the safety of vaccine?

—— The source and destination of vaccines can be traced, and there is a relatively mature control system.

Is Covid-19 vaccine safe? This is the public’s greatest concern about vaccines.

The reporter learned that at present, the vaccination of key populations in China is being carried out in an orderly manner, and the vaccination of high-risk groups (elderly people, patients with basic diseases, etc.) has also been implemented in some areas. Mi Feng, spokesperson of the National Health and Wellness Commission and deputy director of the Propaganda Department, said that after clinical trials have obtained sufficient safety and effectiveness data, the country will carry out vaccination for the elderly over 60 years old on a large scale.

Li Bin, deputy director of the National Health and Wellness Commission, pointed out that there are two main factors affecting the public’s willingness to vaccinate at present: First, China’s epidemic prevention and control is strong and appropriate, and some people think that the risk of infection is low, so vaccination is not needed for the time being to increase protection; Second, because Covid-19 vaccine belongs to the newly listed vaccine, some people hope to see more information about the use effect of the vaccine. Everyone is very concerned about the data on safety and effectiveness, and consider knowing more about the vaccine before vaccination.

Li Bin said that the best way to prevent COVID-19 is vaccination. Vaccination can reduce infection rate, severe disease rate and death rate; At the same time, the more people are vaccinated, the more people have immunity, which can effectively control the spread of Covid-19 among people.

"Judging from the effect of vaccine use, the Covid-19 vaccines currently used in China have been clinically studied according to the specifications, approved by the State Drug Administration, and can only be used after strict verification." Li Bin said that during the storage and transportation of vaccines, it is required to regularly detect and record the temperature, so as to ensure that the vaccines in Covid-19 are in the specified temperature environment and meet the transportation requirements. "In the process of vaccination, we have increased personnel training, requiring medical staff to strictly implement the operating rules of’ three inspections, seven pairs and one verification’, and fully guarantee the effectiveness and safety of the vaccine through standardized operations. With the comprehensive development of vaccination work in Covid-19, the number of people vaccinated is also increasing. I believe that the effect of vaccine use will be further revealed. I hope more people will actively participate in vaccination work and let the broad masses of people vaccinate as soon as possible. Let’s witness the vaccine together. Protective effect. "

What should I do if there is an adverse reaction?

The existing data show that the vaccine is safe. The public should read the contraindications carefully before vaccination.

Vaccine safety is guaranteed, so what should be done in case of abnormal reaction?

In this regard, Li Bin said that the state has organized general hospitals at or above the second level to be responsible for the medical treatment and protection of vaccination sites, dispatched experienced emergency personnel to carry necessary medical equipment, medicines and other on-site protection, and dispatched 120 ambulances to be on duty at the scene. Strictly train the personnel involved in medical treatment to ensure that the suspected abnormal reaction can be identified in time and immediately disposed of. Smooth referral channels, establish a green channel for treatment, and fully organize treatment.

He Qinghua pointed out that before vaccination with Covid-19 vaccine, the public must report their situation to doctors. People with allergic vaccine ingredients, angioneurotic edema, dyspnea, epilepsy or other nervous system diseases, a history of Guillain-Barre syndrome and pregnant and lactating women should not be vaccinated with Covid-19 vaccine.

Wang Huaqing, chief expert of immunization program of China CDC, said that the vaccine is an exotic antigen to human body. Due to the characteristics and individual differences of the vaccine, there may be some adverse reactions after vaccination, but the incidence of adverse reactions is generally low. Before vaccination, the public must read the contraindications carefully, and if they have a past medical history and medication history, they must give truthful feedback to the vaccinator. At present, the incidence of adverse reactions of Covid-19 vaccine is similar to that of previous vaccines, and there is no abnormality.

"The adverse reactions we are monitoring now mainly include local reactions and systemic reactions. The manifestations of local reactions are pain, redness and swelling after inoculation, and some may have induration, but these local reactions can heal themselves without treatment. There are relatively many systemic reactions, some are headaches, fatigue, and some have low fever. " Wang Huaqing said.

Wang Huaqing said that China has strict and meticulous investigation and diagnosis procedures for adverse reactions. Inoculators should seek medical treatment in time if they encounter suspected adverse reactions. In the process of diagnosis and treatment, clinicians will form a report if they suspect that it is caused by the vaccine. "If the report is a suspected abnormal reaction to vaccination and it is suspected to be related to the vaccine, we will investigate the more serious suspected adverse reactions involved in the follow-up. In the process of investigation, some cases need to be examined, and their vaccination history and the occurrence of the whole disease should be known, and finally the expert group will make a diagnosis. This requires a process and a certain amount of time, and we will continue to track and evaluate these. " (Reporter Zhang Yaxiong)

　　Cctv news In order to fully demonstrate the practice and achievements of Nanjing in promoting the modernization of social governance since the 18th National Congress of the Communist Party of China and introduce the future objectives, tasks and key tasks. On the morning of September 15th, Nanjing held the eighth news conference on the theme of "Striving for a New Nanjing and Building a New Era" — — Special session on social governance. At the meeting, Jin Nan, member of the Party Committee and deputy director of the Municipal Urban Management Bureau, introduced the practice and achievements of Nanjing in continuously promoting the rule of law, standardization and refinement of urban management in recent ten years.

　　In the past ten years, Nanjing urban management system has continuously changed its working concept, innovated its working ideas, explored its management mode, and strived to achieve a new leap and development in urban management.

　　With the "Embroidery Kung Fu", the functional quality of urban environment has been significantly improved.

　　By renovating the "small incision" to promote the "great change" of the environment, Nanjing urban management system has innovated the sanitation and cleaning mode, and the level of refinement of sanitation operations has been greatly improved. The mechanized cleaning rate of urban main roads in the city has reached 100%, and the primary and secondary roads in suburban parks have reached more than 98%. Significant progress has been made in the construction of sanitation facilities, and a number of key projects, such as Jiangbei Incineration Power Plant, have been completed and put into operation. The incineration treatment capacity of domestic waste in the city has reached 8,010 tons/day, the centralized treatment capacity of kitchen and kitchen waste has reached 2,150 tons/day, and the harmless treatment rate of domestic waste has reached 100%. The city has taken on a new look, adhered to the principle of "one lane, one policy", explored and completed the modes and mechanisms such as hierarchical management and autonomous alliance, and on the basis of retaining the historical features and texture of streets and lanes, paid attention to continuing the context and keeping the ancient as the new, and comprehensively rectified and upgraded 2,305 back streets and lanes represented by Dabanxiang and Nanhu East Road through "small-scale and gradual" micro-renovation.

　　Practicing the purpose of serving the people has significantly enhanced the happiness of the citizens.

If a child is allowed to watch these works in front of Roscoe’s Orange and Yellow, Newman’s Achilles and mondriaan’s Composition of Red, Yellow and Blue, the child will proudly say, "I can draw them too". If an adult is allowed to appreciate these works, it may not be long before they will have a helpless doubt. Is this art? Maybe turn around and watch Warhol’s Golden Monroe or Jones’s Flag.

But on the whole, contemporary art has gone further and further in the direction that people can’t understand, which will inevitably make people wonder, "Is this the natural trend of art, or is it deliberate by artists?" If we want to solve these problems, we should go back to the embryonic stage of abstract art, and perhaps we can find the reasons for all this in an artist who was regarded as a rebel pioneer at that time.

If you need to identify a person, Kandinsky is undoubtedly the best candidate. Wassily kandinsky was born in Moscow in 1866. He loved painting as a child, but it was not until he finished his legal studies at the age of 30 that he devoted himself to painting, gave up his stable professorship and went to Munich to study painting. By 1923, his presentation of color was perfect and as precise as science, and he also taught at the famous Bauhaus school. Kandinsky moved to Paris during World War II and died in 1944.

Kandinsky, together with mondriaan and Malevic, is regarded as the pioneer of abstract art, but Kandinsky is more outstanding in terms of the thoroughness of abstract painting and the study of abstract art theory. His essays on the Spirit of Art in 1911, On Form in 1912, Point, Line and Surface in 1923, and On Concrete Art in 1938 are all classic works of abstract art, which are the key to deciphering the code of modern abstract art.

However, if we want to understand the opportunity of the development of modern abstract art through Kandinsky, we should first simply trace back the artistic concept, especially the change of the concept of painting. As early as in ancient Greece, Plato thought that art was "imitation", but the imitation he said was not an imitation of nature, but a perfect "rational" imitation of his ideal thing.

Plato himself did not admire art, but his imitation theory was handed down all the way. Leonardo da Vinci once said, "The most praiseworthy painting works are those that can depict things as they are." It can be seen that in the classical period of western painting, its focus was on "object image", that is, the reaction to the painting object (real thing).

The biggest impact on painting art should be the emergence of photography technology, which makes painters feel threatened by science-since photography can perfectly reproduce objects, what direction should painting develop? At this time, a group called Impressionist painters appeared in history. They answered this question with their own exploration of works, and painting art started the modern process by them, and also started the revolution completely divorced from objects.

In Spirit in Art, Kandinsky summarized the complex ways of creating paintings into three categories:

First, the direct impression from nature is expressed in pure painting form. I call it "impressionism".

Second, it originates from the subconscious, and it is an intangible and spontaneous expression of inner character. I call it improvisation.

Third, the expression originated from slow emotional brewing has undergone almost harsh inspection and processing. I call it "constructive". In this composition, reason, consciousness and will all play a guiding role, but everything ultimately depends on feeling and has nothing to do with measurement.

The appearance of Impressionism is the beginning of the resistance to "physical images", and the result will inevitably lead to a complete betrayal of the classical imitation concept expressed by "abstraction".

Kandinsky believes that the core issue of art has changed from "how to express" to "what to express". That is, in the field of classical painting, painters pay attention to techniques, colors, perspectives, and whether objects can properly express their themes, all of which remain at the level of how to express them. When entering the field of modern art, artists go further in the exploration of the original techniques, and what to express with art is the starting point and the end point of all artistic behaviors.

"Not painting, but painting" is Kandinsky’s self-demand. Only by getting rid of the imitation of things can the painter truly enter a free expression situation, and the pure construction of pictures can reflect the "internal drive" that Kandinsky pursues. In his paintings, Kandinsky pursues the human spirit, which is the transcendence of reality, and in the transcendence, he obtains a sacred spiritual experience close to religion.

"At present, the expression of every art tends to be non-reappearance, abstraction and internal structure." By understanding Kandinsky’s requirements for art, we can understand that abstract works will inevitably appear in Kandinsky’s artistic career. Artists regard free expression as their pursuit and break the inherent form of expression as the direction of breakthrough, then the simulation of objects will inevitably be completely abandoned in the field of painting.

Of course, Kandinsky does not deny objects. He thinks that the core elements of painting are form and color, just as Picasso’s works pursue more form, while Matisse shows more colors.

As for form, Kandinsky thinks that form is the external expression of inner meaning, which aims at either depicting concrete two-dimensional objects or maintaining purely abstract entities. Therefore, the form can take two paths: pure image and pure abstraction.

However, the problem is that there is no pure object image, that is, 100% reduction of objects. Even in photographic works, there are many problems such as angles, and it is impossible to show objects purely. Therefore, Kandinsky believes that the expression of pure object images will inevitably move towards the road of "idealization" and "stylization". Just like the popular art we are familiar with, it is basically the pursuit of object-oriented style expression.

Pure abstraction can completely exist in the art of painting. After being separated from the object, pure abstraction can give the author the maximum freedom of expression, and at the same time, it also removes the interference of the object, and painting becomes the carrier of the author’s spiritual activities completely.

Therefore, Kandinsky chose the freest, but perhaps the most risky and incomprehensible road, and expressed his inner driving force of art with pure forms, namely points, lines and surfaces, and colors. He believes that this driving force of art has three major factors: personality, style and pure art. In pure abstract works, Kandinsky showed his own personality, created his own style, and completed the pursuit of true and pure art.

In Kandinsky’s abstract works of art, he has constructed a complete set of expressions. In this world, colors are dynamic, emotional and at the same time have sounds, while points are silent words, lines are the movement of points, and surfaces are the interaction of lines. As a result, Kandinsky’s works have formed a set of expression codes with the most basic forms and colors. In other words, all abstract works are cryptic expressions, and the most interesting thing about them is that the key of this cipher is in the mind of every viewer, and everyone can unlock a Kandinsky or mondriaan that belongs to them completely, which may be the unique charm of modern abstract art..

CCTV News:Summer is hot, and the popularity of inbound tourism is also rising. More and more foreign tourists "come as soon as they speak" and experience the charm of Chinese culture for themselves.

The data shows that at present, the "144-hour transit visa-free" policy implemented in 15 provinces (autonomous regions and municipalities) and 34 ports in China is quite popular. Every travel agency with international business is full of orders, and many foreign friends want to visit China.　

Among various cities, Beijing, Shanghai, Guangzhou, Shenzhen, Chengdu, Hangzhou, Suzhou, Xi ‘an, Chongqing and other cities are favored by foreign tourists.

In order to let foreign tourists know more about China’s tourism resources and culture, Qinhuangdao City, Hebei Province has continuously enriched the format of cultural tourism to attract foreign tourists.

In Jiaoshan Scenic Area, Qinhuangdao, a delegation composed of seven Russian travel agencies started this year’s trip to China. They boarded the Great Wall, took photos, learned about the distribution of scenic spots and the guarantee of service facilities, and made a good strategy for taking a group to travel to China later.　

Data show that since the beginning of this year, overseas tourists from more than 40 countries and regions, including Malaysia, Thailand and Russia, have arrived in Qinhuangdao to enjoy a leisure tour of mountains and seas.

A number of international transit passengers passing through Guangzhou participated in a free one-day tour of Guangzhou.

The 144-hour transit visa-free policy has warmed up inbound tourism. On the morning of July 11th, many international transit tourists entered Guangzhou through this transit policy, and participated in a free one-day tour of Guangzhou, becoming the first group of tourists.

Sydney tourist Reza’s family transited to Dubai via Guangzhou. During the transit, the whole family participated in a free one-day tour of Guangzhou.

It is understood that the free one-day tour in Guangzhou covers flower city square, Guang Zhouta, Yuexiu Park and other scenic spots. Visitors can take the tour bus and enjoy lunch for free, and there are English tour guides to explain the whole journey. Combined with the 144-hour transit visa-free policy, passengers with foreign passports who transit at Baiyun Airport can sign up.

A series of visa-free policies have promoted China’s inbound tourism, and Guangzhou has become one of the most popular inbound destinations in China. In the first half of this year alone, the number of foreigners entering Guangzhou Baiyun Airport Port exceeded 2.06 million.

CCTV News:In addition to all kinds of busy shopping and short trips, many people also choose new ways to celebrate the New Year, such as watching movies, exhibitions, visiting museums and soaking in libraries. During the holidays, some large-scale exhibitions and art galleries in Shanghai, Shenzhen and other places opened normally, with the daily passenger flow of Pudong Art Museum reaching 3,000. The Dongyi Art Museum on the Bund is exhibiting 80 works by 29 masters, including Monet and Bonaire. Many citizens came to see the exhibition with their families, and some tourists also came from other places to see it.

Tourist Ms. Yang:Every time I come to Shanghai, I will find one or two art galleries to look at the paintings and enjoy them.

Ms Luan, a citizen of Shanghai:Broaden your horizons. I don’t have to go out of Shanghai, so I think it’s good.

The special exhibitions planned and launched by the major cultural exhibition halls in Shenzhen have also become a hot spot for citizens to rush to punch in. With the help of immersive rendering, image search and panoramic sound, this immersive digital experience exhibition leads the audience to experience the world of patterns in ancient buildings and collections. The audience can enjoy naked-eye 3D "digital cultural relics" up to 5.3 meters and 22 times high-definition magnified cultural relics, and feel the experience beyond the physical cultural relics exhibition.

The Shenzhen Museum is exhibiting "Silk Road Art in Dunhuang Grottoes and Hexi Corridor". According to the requirements of epidemic prevention and control, only 4000 people are reserved every day, but the exhibition is full every day.

Shenzhen, Guangdong citizens:At that time, no matter the color, shape, and the degree of recovery, it looked quite shocking, and I felt that the culture of China was too extensive and profound.

Shenzhen, Guangdong citizens:Time was tight when I went to Dunhuang before, so you can enjoy it slowly at home.

Many places have also launched the "New Year in the Museum" activity, and libraries, theaters and cinemas are full of popularity. Search platform big data shows that during the Spring Festival holiday, the consumption of tourism, culture, entertainment and other services showed a rapid growth momentum, with "post-80s" and "post-90s" as the main consumers. In the top ten popular Spring Festival activities this year, watching movies is still everyone’s first choice. As of 21: 00 on February 6, the total box office of this year’s Spring Festival has broken 6 billion yuan.

　　At the foot of Rihan Mountain (Banla Mountain) in the remote Luhai, Haoletugaole Town, Xiwuzhumuqin Banner, Xilin Gol, the birch forest is slender and tall, the golden lotus is in full bloom, the grassland is fresh and lush, and the scattered yurts are full of cattle and sheep and horses. July is the tourist season, and the brain stem Baolige Gacha, the "most beautiful village" and "China ethnic minority village", is full of tourists.

　　In the interview, the local people told us that the brain stem Baolige Gacha is rich in water resources and there are many kinds of plants, including more than 100 kinds of medicinal plants and more than 30 kinds of trees. It is rich in mushrooms, bracken, yellow flowers and other specialties, and there are more than 200 kinds of wild animals, such as wild boar, hare and deer. It is one of the regions with the longest grassland culture and the most complete preservation in Inner Mongolia so far.

　　"In the past two years, the local infrastructure has been gradually improved, with 100% access to roads and 80% access to electricity & hellip; …” Mori Gendalai, secretary of the Party Committee of Haoletu Gaole Town, tells about the changes in the brain stem Baolige Gacha.

　　On this basis, the "Shepherd’s Home" has sprung up. Here, food, shelter and play are integrated, and ecological culture tour, nomadic culture tour and folk customs tour are combined to bring tourists different grassland experiences. "On the basis of developing animal husbandry, we will continue to increase the development of the tertiary industry, so that animal husbandry and tourism can develop harmoniously and complement each other." Mo Rigen Dalai said with a smile.

　　Leave the "Banla Mountain" in Xiwuzhumuqin Banner and come to the "Horizon Grassland" Wulagai. The scenery here is still intoxicating, not only the picturesque Jiuqu Bay, but also the grassland Lingquan Bulinquan and the location of the movie Wolf Totem. These scenic spots are not far apart and strung into a complete tourist route, laying a good foundation for the local development of global tourism. "Wulagai officially began to develop tourism in 2016 and experienced a process from scratch." Hu Mingkai, director of the Culture, Sports, Radio, Film and Television Tourism Bureau of Wulagai Management Zone, lamented.

　　However, the development of grassland tourism should be organically combined with grassland protection. "In the case of meeting the basic needs of tourists, it is necessary to minimize the damage to the grassland ecological environment caused by the development of tourist attractions." Hu Mingkai introduced that Wulagai attaches great importance to grassland ecological protection while developing characteristic tourism. For example, wooden trails are specially laid in Jiuqu Bay Scenic Area to prevent grassland from being destroyed by human beings; Arrange the accommodation places for tourists outside the scenic spot to prevent pollution in the scenic spot.

　　"Grassland herders eat tourist meals, and we should cherish the green mountains and waters and take good care of the blue sea and blue sky." Tara, a herdsman in Jiuqu Bay, said.

　　Smart pasture and ecological pasture bring new atmosphere to the optimization of industrial structure.

　　In a 6,000-square-meter cowshed in Hersge Ranch, Wulagai Management Area, herders are feeding hundreds of beef cattle with special formula feed. "The varieties we introduced from abroad, including Angus cattle and Simmental cattle, can only reach 250 kilograms in three years, and these cattle can reach 350 kilograms in 12 months." Hugue Gilletu, head of Hersge Green Industry Import and Export Co., Ltd. said.

　　Traditional animal husbandry is overloaded with grazing, which brings damage to grassland ecology and is not conducive to the sustainable development of animal husbandry. What impressed Hugue Gilletu was that when he first came to the management area three years ago, the grazing time here was six to seven months, but now it has been shortened to three months. "Now in mid-July, many cows are still locked up, just to protect the grassland ecology."

　　Not only that, the company also provides local herdsmen with improved cows (bulls), embryos, frozen semen, technical training, mechanical equipment, order recovery of calves, procurement of high-quality pasture, etc., and has established a joint mechanism of sharing interests and risks with herders, which has led to the development of standardized scale farming by cattle farmers in the surrounding areas and even the whole alliance, and promoted the income of herders.

　　On the prairie, there are not only ecological pastures, but also many smart pastures.

　　In Saihantala Gacha, Mandula Town, Sunite Zuoqi, Xilin Gol League, 50-year-old Baolidao Bater, like most herders on the grassland, often rode horses or motorcycles to drive livestock to graze in his early years, and went out for a whole day. However, he never dreamed that he could now sit at home with his mobile phone in front of the screen and manage more than 600 sheep.

　　In the new energy room of Bater’s home in Baolidao, the shepherd only needs to click the mouse, and the high-definition images such as the position of the flock and the passing vehicles can all appear on the smart TV screen. In addition, the mobile smart ranch App can also remotely control the switch of the sink, so that herders don’t have to go to the pasture to feed the cattle and sheep. "Nearly 10,000 yuan of complete equipment, after government subsidies, can be installed for only 2,000 yuan." Baolidao Bater said.

　　Nowadays, more and more herders use "smart grazing" like Bater in Baolidao. Chen Xiaogang, deputy director of the Finance Bureau of Sunite Zuoqi, introduced that with the support of the financial modern agricultural development project funds, the Banner Finance Bureau intensified the construction of smart animal husbandry, and developed and built a comprehensive service platform for sheep traceability big data in Su Nite. The project covers 7 Sumu towns and 49 Gacha in the whole banner, and the relevant supporting facilities have been completed nearly 80%, which has provided services for 430 herders and 195,000 animals.

　　After bidding farewell to the days of "chasing sheep" and grazing, Baolidao Bater used his spare time to run a Mongolian restaurant. "Once the mobile phone monitors that the moving speed of the flock is abnormal or beyond the grazing range, the system will call the police and I will drive back from the restaurant in time." Baolidao Bater said with alacrity.

　　Grassland herders enter urban communities and start a new model of home-based care for the elderly.

　　In Dabu Hillert Community, Bayanchagan Sub-district Office, Xilinhot City, waves of songs and piano sounds came from Aiqile Herdsmen’s Pension Park. In the park, some old people are rehearsing and dancing, some are playing the piano and singing, some are playing chess and cards, and some are cutting paper, embroidering and practicing calligraphy.

　　Huang Decai, a 62-year-old Mongolian man, lived in Aiqi Paradise three years ago. Compared with living in his own yurt, it is much more convenient here. For example, every morning, the restaurant will prepare breakfast. After dinner, you can have tea and chat with the old people in the park in the leisure square, or go to the activity center to exercise. "Almost all the herdsmen who used to live in the same village with themselves have come here, and the neighbors are familiar with them."

　　What makes Huang Decai more satisfied is the convenient medical service here. "If you are not feeling well, make a phone call and the medical staff will come, next to the hospital and pharmacy." Huang Decai said through the window, pointing to the opposite building.

　　Aiqile Herdsmen’s Pension Park has a total construction area of 30,000 square meters and 990 designed beds for the aged. Health service stations, activity centers, restaurants, supermarkets and other hardware in the park are fully equipped, forming a comprehensive service system for the aged that can meet the needs of the elderly, such as food, clothing, housing and transportation. The park was officially opened in September 2014, and 495 households and 828 elderly people have moved in, realizing that 70% of the elderly in the pastoral area of Sumu Town have moved to the city to provide for the elderly.

　　Li Xiaoyu, director of Bayan Chagan Sub-district Office, told me that in addition to the convenience and guarantee of food, clothing, housing and transportation, there are frequent community activities in the park every year. For example, carry out traditional folk activities such as offering sacrifices to fire and Aobao in off-year and competitions with national characteristics such as Galaha, Mongolian chess and Nadam conference; Encourage the production of handicrafts in the park, hold handicraft sewing competitions, set up exhibition areas in the comprehensive service center, and promote and sell handicrafts in the park as tourist commodities. "It enriches the spiritual and cultural life of herders, and the original ethnic customs make everyone get in, stay and be happier." Li Xiaoyu said.

　　It is learned that Aiqile Herdsmen’s Pension Park adopts market-oriented operation, and the service center signs occupancy agreements with elderly people who are willing to stay and meet the requirements, and each household charges 300 yuan every month; At the same time, the government also provides policy support and subsidizes large-scale maintenance, maintenance and operation in the park, which effectively reduces the economic burden of the elderly living in pastoral areas and reduces the cost of the elderly living in cities.

　　"We are still exploring this old-age care model. In the future, we plan to further improve hardware facilities and innovate old-age care services, so that old people can have a sense of gain, happiness and security here." Tang Guiju, director of Xilinhot Civil Affairs Bureau, said.

Cervical cancer is one of the common malignant tumors that seriously threaten women’s health all over the world. At present, the prevention and control of cervical cancer in China is facing the problem of low coverage of screening population, especially in areas with low health resources, and it is difficult to achieve early detection and early treatment of cervical cancer with weak primary screening technology. How to improve the level of cervical cancer screening in areas with low health resources? What role can digital technology play? Distinguished professor Qiao Youlin, School of Medicine and Public Health, Peking Union Medical College, accepted an interview with a reporter from CCTV.

Cervical cancer is different from other cancers. It has a state of precancerous lesions, which can last for 10 years or more. Qiao Youlin said that if the precancerous lesion state is found through high-precision screening, it is simple and cheap to treat at this time, and good treatment results can be obtained.

With the progress of science and technology, the time of cervical cancer screening is gradually advanced. Initially, there were no cytologists and high-tech HPV detection technologies in areas with low health resources. At that time, our obstetrician put acetic acid on the cervix, and if there was any lesion, there would be a white lesion, which was called acetic acid white staining test. Later, it was improved to cytological examination, and whether cytology has changed with a microscope made the diagnosis more accurate. Further development, to use molecular biology methods to check the nucleic acid of the virus. In this way, it can be detected when the virus has just been infected without causing cytopathy. Qiao Youlin said that it is precisely because the World Health Organization has seen that cervical cancer has a vaccine and that screening technology has improved that we can eliminate cervical cancer. .

Each country has its own regulations for defining the age of cervical cancer screening. Generally, the age of government-led screening in our country is defined as 35 to 64 years old. Qiao Youlin said that if ordinary people want to go to the hospital for examination by themselves, they can have a cytological examination at the age of 25. If it is HPV testing, you can do it at the age of 30.

The World Health Organization proposes that cervical cancer should be eliminated globally, and adult women aged 35 -64 should be screened regularly. At present, there are two plans in China: one is to check once every three years and use cytological methods to detect; One is to check once every five years, using HPV detection technology. Qiao Youlin said that adult women between the ages of 35 and 64, if they check every three years, need to check 10 times in their lifetime; If you check it every five years, you only need six checks in your life. In 2019, the state decided to include the "two cancers" screening of cervical cancer and breast cancer in the scope of basic public health services. Qiao Youlin said that it is difficult to implement the policy in areas with low health resources. One is the lack of financial resources, and the other is that the improvement of health service capacity is not so fast. To eliminate cervical cancer in areas with low health resources, it is necessary to find a simpler, easier to operate and more efficient detection technology.

At present, HPV detection technology is being promoted in areas with low health resources. This technology is based on machine detection, which only needs sampling, and the machine produces the results, so it is not necessary to rely on doctors to look for a needle in a haystack under a microscope. Qiao Youlin said that he hopes to train the staff of maternal and child health hospitals in areas with low health resources in three years and teach the grassroots to master this technology, so that the screening of cervical cancer can be continuously promoted.

At present, the most difficult thing in cervical cancer screening is colposcopy biopsy, which is the bottleneck of secondary prevention of cervical cancer, that is, early diagnosis and treatment. Qiao Youlin said that our team is developing an artificial intelligence-based colposcopy biopsy assistant tool with the Health Pratt & Whitney Laboratory of Tencent’s Sustainable Social Value Division. It can be clear where to biopsy, and obtaining accurate biopsy point information will make doctors more confident. Qiao Youlin has been working in the front line of disease prevention and treatment, especially cancer prevention and treatment for a long time. He said that he deeply felt the great changes brought by digital technology, such as the simplest physical examination. You need to know who you are looking for and whether this person meets the conditions for physical examination. Intelligent management of the crowd and dynamic management according to individual’s specific health status make the prevention of diseases more refined and the health service more refined, and the cost-effectiveness is also cost-effective.
