Cctv newsAffected by continuous heavy rainfall, wind and hail and heavy rain occurred in Jinchuan County, Lixian County and Marcand City in Aba, Sichuan Province, and floods and mudslides occurred in many places, and many national highways were once interrupted.

　　　　　　 The reporter learned from the Emergency Office of Jinchuan County that as of June 14th, geological disasters caused by heavy rain have caused the interruption of G248 line and Jinxiao Road in Jinchuan, and farmland, water conservancy and houses in various towns and villages have been affected to varying degrees. After the disaster occurred, Jinchuan County urgently organized emergency personnel from water affairs, emergency, highway, electric power and other departments to rush to the scene, fully devoted themselves to emergency rescue and disaster relief and mass appeasement, and safely transferred 863 people. According to statistics, up to now, 1,186 households with 4,744 people have been affected to varying degrees, and the economic losses are being counted. In addition, the torrential rain also triggered mountain torrents and mudslides, which led to subgrade collapse in Dengjiaqiao section of Malcom City, National Highway 248 in Aba Prefecture, and the section of Jianbi Village in miyaluo, Lixian County, National Highway 317 was once interrupted. After urgent repairs, two sections have resumed traffic.

　　This month, when Hainan inspected and investigated, the Supreme Leader General Secretary profoundly pointed out: "Green mountains and green hills are reservoirs, grain depots, Qian Ku and carbon depots."

　　Last month, when the General Secretary participated in the voluntary tree planting activities in the capital, he stressed: "Forests are reservoirs, Qian Ku and grain depots, and now we should add another one ‘ Carbon pool ’ 。”

　　As early as during his work in Ningde, the Supreme Leader put forward the scientific judgment of "Reservoir, Qian Ku and Grain Depot", which pointed out the direction for the revitalization of eastern Fujian.

　　Consistent concept, as always, feelings, a grasp of the end of the responsibility.

　　From a city’s green development practice to a country’s green development concept, every inch of time has dyed beautiful China green. In the green mountains and green hills described by the General Secretary, there are treasure houses that benefit the people and the descendants of Zebei.

　　Contained water is the reservoir, nourishing great rivers and mountains.

　　Hainan Tropical Rainforest National Park, a dewdrop falling on bougainvillea blooms bright rose; In the Jiuqu River of Wuyishan, thousands of water drops gather into a "green ribbon", stroking the towering peaks … … Water is the source of life, the key to production, the foundation of ecology, and also the foundation for maintaining the ecosystem.

　　"An advertisement says ‘ The last drop of water on the earth is human tears ’ We must not let this happen. " General Secretary of the Supreme Leader is far-sighted and puts forward that "from the strategic height of building a well-off society in an all-round way and realizing the sustainable development of the Chinese nation, we should attach importance to solving the water security problem."

　　Water security is inseparable from the supply of boiled water. To solve the problem of water supply, we should start with water conservation and repair the damaged ecology. Rivers, lakes, forests and wetlands are green "natural reservoirs".

　　The "China Water Tower" originates from the three rivers, which is of great significance to ensure that "one river of clear water flows eastward". The General Secretary profoundly pointed out: "Areas with important ecological functions, such as Sanjiangyuan and Qilian Mountains, should not develop industrial economy, mainly to protect ecology, conserve water sources and create more ecological products."

　　Qinling Mountain, the "central water tower", is an important water conservation area in the Yellow River and Yangtze River basins. The general secretary inspected the protection and restoration of this "ecological security barrier" on the spot and planned the direction of the sustainable development of the Chinese nation.

　　The green hills are not old, and the green water keeps flowing, nourishing all things and moistening all directions.

　　Accumulate grain as a storehouse and stabilize China’s rice bowl.

　　Cang Li Shi, the world is safe. Food security is "the biggest in the country".

　　In April, in Nanfan Scientific and Research Breeding Base, Hainan, the spring breeze blows the green fields, and the rice paddy has thousands of waves.

　　Four years ago, General Secretary of the Supreme Leader walked into the "Chaoyouqian" super hybrid rice exhibition field along the ridge to see the growth of rice. During his inspection in Hainan this year, the General Secretary came to Yazhouwan Seed Laboratory at the first stop, stressing: "If Chinese’s rice bowl is to be firmly in his own hands, he must firmly hold the seeds in his own hands."

　　Good ecology and abundant products. The largest breeding base in South China was built here, which benefited from the unique light and heat conditions and Hainan "has the best ecological environment in China".

　　Looking around, from the "rice fragrance along the Hailan River" in Yanbian, Jilin, to the "China Green Midou" in Jiansanjiang, Heilongjiang, and then to the "Small Jiangnan in Northern Shaanxi" surrounded by terraces in Gaoxigou Village, Shaanxi … … Yellow land, red land, black land, trip to Wan Li, feeling the same.

　　At the two sessions this year, the General Secretary mentioned "establishing a big food concept" and pointed out that "on the premise of protecting the ecological environment, it is necessary to expand from cultivated land resources to the whole land resources, and to form a modern agricultural production structure and regional layout that adapts to market demand and matches the carrying capacity of resources and environment."

　　Asking for food from forests, rivers, lakes and seas, and facility agriculture is the "China rice bowl".

　　Gather wealth as a repository and explore ways to get rich.

　　In Yucun, Anji, Zhejiang, there is a memorial stone tablet engraved with "Lucid waters and lush mountains are invaluable assets" at the head of the village. It is here that Comrade Supreme Leader first put forward the scientific conclusion of "Lucid waters and lush mountains are invaluable assets".

　　“‘ Lucid waters and lush mountains are invaluable assets ’ This is actually value-added. " Improving the ecological environment means developing productive forces. Only by giving full play to ecological advantages can we achieve high-quality development.

　　In Zhoushan Farmhouse, Zhejiang Province, the general secretary and villagers’ representatives sat together and said, "This is a natural oxygen bar, which is ‘ Beautiful economy ’ It confirms the truth of Lucid waters and lush mountains are invaluable assets. "

　　In Chagan Lake, Jilin, the General Secretary had a cordial conversation with the staff of the fishing ground, emphasizing that "green mountains and green mountains, ice and snow are all Jinshan Yinshan. Protecting the ecology and developing eco-tourism complement each other, and this road must go down in a solid way. "

　　Hearing the grass-roots representatives talking about the "Forest Symphony" in Daxinganling, the general secretary said with a smile: "The total ecological value you mentioned is the concept of green gdp, which shows that ecology itself is value."

　　Good natural ecology contains great economic value. Under the guidance of the scientific concept of "Lucid waters and lush mountains are invaluable assets", thousands of villages in Qian Qian have achieved ecological beauty, prosperous industries and rich people, and embarked on the road of green development to get rich.

　　Carbon sink as a reservoir to build a green home together

　　Many trees make a forest, lush, and a forest is a carbon storage.

　　When he participated in the voluntary tree planting activities in the capital last year, the General Secretary of the Supreme Leader pointed out that "increasing the increment of carbon sink in the ecosystem"; In this year’s voluntary tree planting activities, the general secretary once again mentioned "consolidating and enhancing the carbon sink capacity of ecosystems".

　　"Carbon dioxide emissions will peak by 2030 and strive to achieve carbon neutrality by 2060." On September 22, 2020, the Chairman of the Supreme Leader made a solemn commitment at the general debate of the 75th United Nations General Assembly.

　　Keep what you say and carry out what you do. On March 15th last year, the General Secretary presided over the ninth meeting of the Central Financial and Economic Committee. The meeting pointed out that improving the ecological carbon sink capacity, strengthening the land spatial planning and use control, effectively exerting the carbon sequestration function of forests, grasslands, wetlands, oceans, soils and frozen soil, and increasing the carbon sink increment of ecosystems. On August 23 last year, in Moon Mountain of Saihanba Mechanical Forest Farm, the General Secretary earnestly entrusted him with "bold exploration in enhancing carbon sink capacity and effectively building an ecological barrier between Beijing and Tianjin".

　　China’s dedication highlights the role of a big country and contributes wisdom and strength to promoting global environmental and climate governance and jointly building a community of life on Earth.

　　"The lifeblood of man lies in the fields, the lifeblood of fields lies in water, the lifeblood of water lies in mountains, the lifeblood of mountains lies in soil, and the lifeblood of soil lies in forests and grasses. This life community is the material basis for human survival and development." At present, China’s ecological civilization construction has entered a critical period to realize the improvement of ecological environment from quantitative change to qualitative change, and the infinite value contained in green water and green mountains will be continuously released with the continuous strengthening of China’s ecological civilization construction.

On April 18th, Chery started the pre-sale, and the new car launched a total of four configuration models, with the pre-sale price range of 159,900 to 199,900 yuan. Fengyun T9 positioned a compact SUV equipped with Chery C-DM hybrid system.

At the pre-sale conference, the official said that 9.9 yuan can participate in crowdfunding or lottery if it orders. When the total order volume is less than 10,000, the listing price will be reduced by 5,000 yuan, and so on, the highest price will be reduced by 20,000 yuan.

Fengyun series is a brand-new energy sequence of Chery brand, which was officially released in November last year. At the same time, it will adopt a brand-new product Logo, and it will launch 11 brand-new models in the next two years, based on Chery Kunpeng’s super C-DM hybrid technology.

Under Chery’s new energy brand system, there are currently four new energy brands: Chery New Energy, Jietu, Xingtu and iCAR, and the Fengyun sequence in Chery New Energy has been restarted into a hybrid brand, and Xingtu’s Star Era is defined as the high-end brand of Chery New Energy.

Fengyun T9 Appearance & Interior Appreciation

As Chery’s brand-new energy sequence, we feel a strong "new energy smell" from its front face design. The front face of the new car adopts a large-area closed grille, but the traditional grille position still adds matte silver trim strips to outline the shape, which is very aura as a whole, while the air inlet for the engine is hidden under the front face.

Coming to the side of the car body, Fengyun T9 uses privacy glass in the back row, and there are not too many complicated lines in the whole car body. The shape of the traditional SUV benefits from the size and also shows its gas field.

The detailed design part, now hidden door handles, large-size wheels and so on have been given.

In terms of body size, the length, width and height of the new car are 4820X1930X1710mm and the wheelbase is 2820 mm.

The shape of the tail echoes the front face, adopting the design of penetrating taillights, with Chery’s LOGO in the center, and the whole tail seems to have a wide horizontal vision.

In terms of interior, Fengyun T9′ s style is also consistent with the current mainstream. In the center console of the car, there is a large-size floating screen with an estimated size of 15.6 inches, and it is expected to be equipped with Qualcomm Snapdragon 8155 chip, which will bring high vehicle performance and look forward to the subsequent static performance experience.

The main driving instrument also uses a separate floating screen with an estimated size of 10.25 inches.

Other features include zero-gravity seats, wireless charging function of large wattage mobile phones, ventilation, massage and heating of front and rear seats, and other comfort configurations.

In terms of power, Fengyun T9 this time is a hybrid model, with Kunpeng power, 1.5T engine, 3DHT gearbox and CDC suspension system. There will be two versions of two-wheel drive and four-wheel drive. The maximum power of the two-wheel drive motor is 165kW, and that of the four-wheel drive motor is 340kW.

In terms of battery life, the two-wheel drive CLTC has a pure battery life of 160km, and the four-wheel drive version is 150km；; The comprehensive mileage of two-wheel drive and four-wheel drive is 1320km/1100km, respectively, and the power loss and fuel consumption are 5.7L/100km.

C-DM hybrid system

At present, Chery is fully turning to new energy sources, and the hybrid field relies on the Kunpeng super-performance electric hybrid-C-DM independently developed by Chery, equipped with the fifth-generation ACTECO 1.5TGDI high-efficiency hybrid special engine and the third-speed super-electric hybrid DHT.

Under this platform, it can cover a variety of vehicles and power combinations, including A-B cars, SUVs and MPVs, 5-seat, 6-seat and 7-seat vehicles. In terms of power, it covers 1.5T, 2.0T and 1.5L hybrid special engines, as well as 13DHT and 3 DTH hybrid boxes with different power and torque.

Among them, the fifth-generation hybrid engine is the latest achievement of Chery in the hybrid field, and it has the technical applications of Miller Cycle technology, 4.0i-HEC fourth-generation intelligent combustion system, HTC high-efficiency supercharger, i-LS intelligent lubrication system, i-HTM intelligent thermal management system, HiDS high dilution system and so on.

The power system can achieve the maximum effective thermal efficiency of 44.5%, fuel consumption of 4.2L per 100 kilometers and maximum power of 115kW.

In the aspect of hybrid DHT gearbox, three-speed super electric hybrid DHT and stepless super hybrid DHT are also built. Among them, the three-speed super electric hybrid DHT is based on dual-motor drive and three-speed DHT, which has the characteristics of the highest transmission efficiency of 97.6%, acceleration of 4.26s per 100 kilometers, and torque distribution before and after 0-100%.

The stepless super hybrid DHT also realizes the driving state of non-inductive variable speed through E-CVT, and also has the characteristics of pure electro-acoustic pressure level and average efficiency of 90%.

Long battery life is still popular.

The recently announced new energy penetration rate seems to have exceeded 50%, among which the sales of plug-in and extended-range vehicles with large batteries have performed well. From the perspective of car scenes, most car scenes in the city can use pure electricity and long-distance car oil without worrying about energy replenishment, which has become the mainstream car choice for domestic users.

Nowadays, the pure electric life of the vehicle is basically the same as the extended range, and there is no difference in experience. Therefore, the demand for such vehicles is still strong and will gradually replace the pure fuel vehicles. Just like Chery, it will launch 11 new plug-in models in the next two years, which shows that it has been accumulating power for a long time.

1905 movie network news The film is showing, which combines love, animation, fantasy and eco-environmental protection concepts. As a national animation film that organically integrates historical events, folklore, cultural tourism and ecological protection, the creative process behind the film is worthy of attention.

A sincere work of Xu Li for six years

The Yangtze River, the mother river of the Chinese nation, has nurtured generations of Chinese sons and daughters and nourished 5,000 years of Chinese civilization. However, over the years, affected by water pollution, overfishing and other activities, the biodiversity of the Yangtze River has continued to decline, the situation of aquatic life protection is grim, and the task of ecological restoration of water areas is arduous.

The creative team is determined to spread the ideas and values of protecting the ecological environment of the Yangtze River and guide the audience to think and reflect through animated films. Among them, the Yangtze finless porpoise, a species that is disappearing and in urgent need of protection, left a deep impression on the creative team. As the only aquatic mammal living in inland waters of China, the scientific investigation in 2012 found that the population of Yangtze finless porpoise continued to drop sharply, only 1045.

Taking endangered species as the theme, telling about its disappearance can arouse the empathy of the audience, so as to feel the urgency of protection urgently.

Realistic visits to stimulate scenario setting

In order to better tell the story of the finless porpoise, The Finless Porpoise Wind Dance sets the scene of the story in Poyang Lake, the largest settlement of the Yangtze finless porpoise at present, where about 500 finless porpoises live, and organizes the creative personnel to collect the wind several times.

In the process of collecting wind, the production team also searched for wild finless porpoises in Poyang Lake basin three times, but all failed, which also made the production team feel the urgency of protecting finless porpoises. Under the arrangement of Hubei Yangtze River Ecological Protection Foundation, the production team saw the artificially raised finless porpoise in Wuhan Baiji Dolphin Museum and photographed precious reference materials.

Talk to people and clarify the core inspiration.

In addition to collecting scenic spots, the production team also visited the frontline protection members of the local finless porpoise patrol team, teachers and students of some schools in Jiujiang, and the finless porpoise protection researchers in Baiji Dolphin Museum.

The core inspiration of the film, "the finless porpoise worships the wind", comes from the conversation with the fish keeper. "The finless porpoise worships the wind" is a folk saying. It is said that when the wind and waves come, the finless porpoise will jump out of the water against the wind and waves, so that people can judge the upcoming storm on the river surface and avoid disasters.

This legend is a very good interpretation of the interdependence between man and nature, and it also has room for further imagination. For example, the finless porpoise jumps out of the water, and the production team can artistically imagine it as a finless porpoise dancing on the river.

Carefully polish the script and give the role deep meaning.

The script of finless porpoise dancing in the wind has been polished and created for more than a year. Screenwriters, producers and directors often discuss the plot late into the night, which gives deep meaning to the three main characters in the film, namely, the heroine Jiang Ling, the male protagonist Lin Sheng and the male second black dragon, and the creative team.

Jiangling — — On behalf of finless porpoises and species in the Yangtze River, they are very helpless and unwilling to face extinction, and naturally they are very attached to the Yangtze River, which has survived for hundreds of thousands or even tens of millions of years.

Lin sheng — — On behalf of human beings, the curse given to him by the Black Dragon represents nature’s vigilance to human beings. The destruction of the Yangtze River ecology by human beings will eventually bite human beings, and human beings must start self-redemption.

The black dragon that is neither right nor evil — — Represents the laws of nature. When the Yangtze River is no longer suitable for the survival of finless porpoises, of course, nature will "take away" the finless porpoises. Of course, this "take away" will not be taken to Yunmengze like in the movie, but will be completely extinct like the baiji.

Conceptual design, restoring aesthetic national style

At the same time of script creation, the work of the art team is also carried out at the same time.The art team artistically processed the scenery of collecting wind and made a concept map. At the same time, some key scenes in the script, such as the magical underwater world, the black dragon leading the finless porpoise to Yunmengze, and the stage of dancing in the wind, were beautifully presented, which provided high-quality reference for the subsequent three-dimensional assets and lens design of the film.

In the movie, Jiang Ling, the heroine, chose the style of Song Dynasty as her usual dress. The main reason is that Hukou County, one of the filming locations, set up Hukou Garrison in the Southern Song Dynasty at the earliest, so it was set that Jiangling was the leader of the finless porpoise at that time and turned into a finless porpoise fairy. Naturally, it was set that Jiangling wore women’s costumes in the Song Dynasty.

The film "finless porpoise dancing in the wind" is being shown nationwide.

Shenzhen News Network September 18, 2023(Shenzhen Evening News reporter Li Chao Intern Yang ZhenyuPeople don’t have to go to work, they can participate in the internship online. In recent years, distance practice has been favored, and many college students practice on the sidelines while studying at school. With the beginning of the new semester, "remote internship" has once again become a hot spot for recruitment platform search. However, there are many problems in remote internship, and the problem of "selling dog meat by hanging sheep’s head" is more prominent.

question

Practice proof becomes practice proof.

The Survey of Students’ Internship 2022 released by Worry-Free Future shows that distance internship has risen among students. Among the data displayed on the homepage of the "Monk of Practice" platform, "Remote" is the first hot search word for users.

Late at night, the reporter directly hired in Boss to see that a well-known tourism platform recruited new media operation remote interns, with the salary marked as 200 to 250 yuan/day, and the job introduction marked that the salary was not calculated by the day, but calculated according to the work effect. The platform shows that the job of this position includes operating and maintaining social accounts to ensure that the account status is active; Write high-quality social platform notes and strategies; Create explosive notes and maintain an interactive atmosphere.

Later, the reporter tried to deliver it late at night and got a quick reply. After writing a 400-word little red book travel guide post as required, he entered the post briefing. At the briefing meeting, the position clearly defined as a remote internship in the recruitment information became a part-time job. The enterprise stressed that it would receive a practice certificate instead of an internship certificate after completing a part-time job for three months. Late at night, the reporter questioned this and got the reply that "this job is a long-distance part-time internship, and it can only be proved by practice". The company did not further explain the mismatch of positions.

experience

The operation of new media has become a "real water army"

Although the actual harvest of the post is different from the job description, the actual work content is consistent with the job requirements, both of which are operating new media accounts.

During the reporter’s experience late at night, it was found that the key nature and matters of his post were deliberately concealed by the recruitment company. The actual work was not to become a member of the company’s official account operation as imagined, but to operate a personal account, and to publish posts with the nature of dark and wide water army in the personal account, and to become a high-quality real-life water army of the company by raising a personal account.

The specific task is to write a drainage post every day with a personal account according to the specified content template, embed the content of drainage and advertising for the enterprise, such as "20% discount coupon for fuel", etc., and embed the new drainage code (6-7 Arabic numerals) generated by each person in the background every day into it to attract and guide users to search for the drainage code and place an order. The audience of the post thinks that what they see is real sharing, but they don’t know that it is a drainage advertisement carefully organized, packaged and approved by the enterprise.

survey

Internship salary is out of reach.

In addition to attracting students in the name of long-distance internship in large factories, the project also set up a detailed incentive mechanism to stimulate students to publish high-quality drainage content.

The recruitment staff of this position said that the salary settlement rule is "basic posting salary+post-breaking reward+new guest reward", and the key indicator is the number of customers, and the monthly salary can reach 8,000 to 10,000 yuan. However, when the reporter experienced it late at night, he found that it was not easy to reach the salary standard. In addition to writing a basic drainage post every day, he also needed four posts with more than 5,000 likes every month, and at least 400 new customers were recruited and the order was completed to reach the monthly salary of 8,000 yuan.

In order to achieve higher salary, distance interns need to constantly improve the quality of drainage posts and attract as many new customers as possible. Lin Lin, a student of "Remote Internship", said that he sent 16 drainage posts in July, which took about 3 hours every day, but he only got a salary of 942 yuan a month. In addition to the traffic harvest, the platform also passed on the risks such as current restriction and titles brought by drainage and darkness to the interns. Lin Lin’s account has been restricted and banned by the platform because of the required drainage and advertising posts. "This time it is 7 days, and the next time it will be 14 days," she said.

popularize law

Unworthy "remote internship" involves illegal activities.

For such "remote internship" positions, Tong Xin, director of Guangdong Guanghe Law Firm, believes that false job introduction is suspected of violating the law. When employing workers, the employing unit shall truthfully inform the workers of their work contents, working conditions, working place, occupational hazards, safety production conditions, labor remuneration and other information that the workers require to know, and shall not publish false recruitment information. If the published recruitment information is untrue or illegal, they will face relevant penalties. Found this situation, have the right to complain and report to the administrative department of labor security.

Tong Xin said that the company set up a long-distance internship position, and recruited college students with conditions such as opening internship certificates and supporting back-tuning, as an act of the company’s real-life water army to drain the darkness, even if it truthfully informed the work-related information, it violated public order and good customs.

At the same time, the enterprise’s recruitment of college students as high-quality real-life water army in the name of new media operation remote internship is suspected of violating many laws and regulations, such as Advertising Law, Regulations on Ecological Governance of Network Information Content, Regulations on Management of Internet Users’ Public Account Information Service, and infringing on consumers’ rights and interests, which is not conducive to the construction of clear network space and fair competition in the market. Traffic fraud involves violations of many administrative, civil and criminal regulations.
