Great Wall Motor donated a pickup truck with a total value of 1.5 million yuan to help Sichuan earthquake-stricken areas.

  Recently, an earthquake of magnitude 6.8 occurred in Luding County, Ganzi Prefecture, Sichuan Province. The disaster situation touched people’s hearts. Great Wall Motor urgently donated 2 million yuan worth of money and materials to help Luding County, Ganzi Prefecture, Zichuan, Shimian County, Ya ‘an City and the surrounding disaster areas. Among them, the Great Wall pickup truck with a total value of 1.5 million yuan was donated to the China Red Cross Foundation for disaster relief materials transportation, emergency rescue in disaster areas and support for subsequent reconstruction.

  After the earthquake, roads were blocked due to landslides, gravel rolling and other reasons, and some roads became narrow and impassable. In the section where big trucks are difficult to pass, pickup trucks donated by the Great Wall can transport materials to the disaster area, support post-disaster reconstruction and enrich the shortage of local rescue vehicles by virtue of their strong passability, ability to get rid of difficulties and loading.

  The Great Wall pickup truck will also pay close attention to the progress of post-disaster rescue and tide over the difficulties with the people in the disaster areas.

  Rushing for disaster relief, empowering public welfare rescue standardization

  All along, Great Wall pickup truck has been actively practicing public welfare and shouldering corporate social responsibility while developing itself.

  Last year, the "7.20" torrential rain in Henan Province, the National Motorists’ Association of the Artillery Alliance gathered overnight, and more than 200 Great Wall cannons rushed to Henan for disaster relief, opening a life channel for more than 4,000 Zhengzhou residents. At the same time, the Great Wall pickup truck acted quickly and launched eight care policies to provide all necessary protection and services for the affected car owners and minimize vehicle losses.

  More than that, Great Wall Artillery also established the first public welfare rescue college in the industry, and launched a centralized training camp focusing on solving the actual rescue situation, aiming to stimulate the enthusiasm of Great Wall artillery riders to participate in public welfare rescue, and also to make public welfare rescue professional and standardized, so that every rescue is awe of life.

  At present, the Great Wall Gun Public Welfare Rescue College has graduated more than 110 users, greatly improving the practical skills of public welfare rescue and empowering users to standardize public welfare rescue.

  Climbing Mount Everest to protect the scientific research and help the national task

  In addition to in-depth rescue in the disaster area, the Great Wall Gun also climbed Mount Everest, crossed the desert and escorted the national scientific research with users.

  In the activities of measuring Mount Everest for three consecutive years, the Great Wall Gun in 2020 helped the country successfully complete the guarantee task of Everest elevation measurement; In 2021, the Great Wall Cannon, together with more than 300 car owners and 120 Great Wall Cannons, stood the test of rain, snow, fog and other complicated weather and gathered at the foot of Mount Everest. In 2022, the full-line pickup truck model of the Great Wall Gun once again successfully arrived at Everest Base Camp to pay tribute to the spirit of climbers.

  The Great Wall Artillery also escorted the successful completion of the scientific research task of Lop Nur, China Academy of Forestry. As the official vehicle for scientific research tasks, the Great Wall Gun, with its all-terrain off-road performance and towing rescue capability, broke through the harsh natural environment, escorted the scientific research workers all the way, ensured the successful completion of the national scientific research tasks as planned, and also contributed to wildlife and ecological environment protection.

How does "online celebrity" become "long red" after a person and a song set a city on fire?

  Reading tips

  With the popularity of social media, a "online celebrity" character and a song can often make a place a punching place for "online celebrity". However, if online celebrity wants to have lasting vitality, it must not only rely on marketing innovation, but also have the competitiveness of product content, including the uniqueness of the product itself and the value it brings to tourists.

  After Ding Zhen became popular, Litang became famous, "going north to Cao" made Cao county out of the circle, and "Mohe Ballroom" brought fire to Mohe … … The emergence of "online celebrity" destinations has brought a new direction to the tourism industry.

  Gu Huimin, a professor at beijing international studies university College of Tourism Science, told Workers Daily that tourist cities can quickly attract attention with the help of the special influence of a special person, event and music, and play a good role in publicity and promotion. Therefore, it is advisable to use the unique advantages of social media to carry out marketing. However, it is an important task for some tourist cities to change "online celebrity" into "Long Red" after its sudden popularity.

  From "Ding Zhen Effect" to Mohe Out of Circle

  Ding Zhen has been popular for more than a year. Driven by the "Ding Zhen Effect", Litang, a small county located in Ganzi Tibetan Autonomous Prefecture, Sichuan, has become a "city of the sky" that many tourists yearn for.

  Affected by this, the local cultural tourism industry has developed rapidly. On October 8, the data released by Litang County Holiday Office showed that Litang County received 137,967 tourists during the "Eleventh" Golden Week, achieving a total tourism revenue of 152 million yuan, a year-on-year increase of 72.4%.

  According to the data of enterprise investigation, there are currently 896 catering-related enterprises in Litang County, with 287 newly registered in the first 11 months of this year, up 85.2% year-on-year; There are 151 tourism-related enterprises, with 26 newly registered in the first 11 months of this year, up 13% year-on-year.

  A person can bring a city with fire, so can a song. Because of a song "Mohe Ballroom", China is the "northernmost town" — — Mohe City, Heilongjiang Province, also made a successful exit.

  On November 17th, the 2021 Winter Tourism Bee Direction released by Ma Honeycomb Tourism and Tencent Travel Service showed that Mohe became the "online celebrity" destination in early winter with a song Mohe Ballroom. After the song was released, the search popularity of "Mohe Travel Guide" in Mahoneycomb Station increased by 166%, and the search popularity of "Mohe Ballroom" increased by 430%.

  In addition, since October 24th, more than 680,000 netizens have watched the Mohe scenery through Tik Tok live broadcast. From October 24th to November 6th, the search volume of "Mohe" in Tik Tok increased by 621% on a biweekly basis.

  Feng Guangqing, director of Mohe Municipal Bureau of Culture, Sports, Radio, Film and Tourism, said in an interview with the media that Mohe Ballroom, like the song Chengdu, can become a local cultural symbol. In the future, we plan to find a suitable location to restore the old ballroom and let this symbol continue to expand.

  The traffic password behind "online celebrity"

  There are many cases in which a song brings fire to a city. Previously, "Chengdu" with a high degree of popularity brought fire to Yulin Road and taverns in Chengdu, and "The Shepherd of Cocoto Sea" also made the beautiful scenery of Altay and Ili in Xinjiang known to more people … …

  "I just got hit by the song Chengdu ‘ Planting grass ’ I just went to Chengdu, especially that sentence ‘ Eager to take a walk in the streets of Chengdu ’ . I went to Chengdu in August last year, and I felt the amorous feelings of that city while listening to songs. It was very good. After listening to Mohe Ballroom, if it weren’t for the epidemic, I would have punched in Mohe. " Ms. Fang, who works in an Internet company in Beijing, told reporters.

  Some experts pointed out that a song can become the cultural brand of a city, and it can also make tourists know and remember the destination. At the same time, the popularity of short videos also enables more users to know more about each city through vivid and interesting content, leaving a beautiful and deep impression, and "weeding" offline through online "planting grass".

  Feng Guangqing said that short video has become a ubiquitous medium, with a huge potential customer base and a vibrant market. If the perspective of short video is human’s perspective, it will give people a sense of substitution and accomplishment. Then there is an array effect on the short video platform. Everyone shoots a punch point and spreads it repeatedly, which will make people want to imitate it.

  "One by one ‘ Online celebrity ’ The emergence of the destination relay has brought a new direction to the tourism industry, with local talents, ‘ Online celebrity ’ The huge economic effects produced by the brand began to appear. " Feng Rao, head of the Ma Honeycomb Tourism Research Center, told reporters.

  Let "online celebrity" City Become a "Long Red" City

  "online celebrity" can not be underestimated in promoting a destination and an experience, so how to cultivate "online celebrity" and make "online celebrity" a "long red" city?

  In order to cultivate a group of local cultural tourism "online celebrity" creators, in November this year, the Shandong Provincial Department of Culture and Tourism jointly launched the "Incubation of Shandong Treasure Players Project" with platforms such as Ma Honeycomb Tourism, and issued recruitment orders for cultural tourism industry practitioners in Shandong Province, such as tourism experts, tour guides, interpreters and non-genetic inheritors, as well as self-media and photographers, with the aim of creating new local tourism highlights and promoting the development of local cultural tourism industry through the local cultural tourism "online celebrity" creators.

  "Local talent itself lives in Shandong and has many conveniences in content creation and output. They not only have a deep understanding of Shandong culture, but also can unlock new ways of playing in time. I hope that by incubating local high-quality creators, they will give full play to the role of spokespersons for cultural tourism and continue to export Shandong’s play inspiration. " The relevant person in charge of the Shandong Provincial Department of Culture and Tourism said.

  However, Gu Huimin pointed out that how to stay popular for a long time after a sudden explosion is an important issue facing some tourist cities.

  "Every city has its own unique image of cultural tourism, which is worthy of further exploration. It can continuously enlarge the traffic by making movies and holding brand activities to create IP." Wei Xiang, a professor at national academy of economic strategy, said that, for example, Changsha Wenheyou has made catering IP very successful, and it has almost become a landmark that must be punched when traveling to Changsha.

  In Wei Xiang’s view, for the "online celebrity" city, if it wants to become a "long red" city, it needs to integrate the cultural tourism industry into the local public service system and supporting urban infrastructure construction. By enriching the supply of cultural tourism products, telling good urban cultural stories and optimizing the consumption environment of cultural tourism, it will bring a sense of gain and happiness to local residents and form an attraction to the outside world.

  Gu Huimin said that if online celebrity wants to have lasting vitality, it must not only rely on marketing innovation, but also have the competitiveness of product content, including the uniqueness of the product itself and the value it brings to tourists. Without innovative products, exciting tourism content, high-quality service, perfect infrastructure and sound market governance, it is difficult to last only through the "online celebrity" effect.

Sodium ion power battery debut, low-cost thousand-kilometer battery life is coming?

Finally, the sodium ion battery is coming!

A few days ago, China Chemical and Physical Power Industry Association announced that from October 8 to November 7, the whole network would solicit opinions on the General Specification for Sodium Ion Batteries. This general specification is mainly applicable to automotive power batteries, energy storage and other fields. If it goes well, it is expected to be released and implemented around November.

Domestic battery companies such as Contemporary Amperex Technology Co., Limited, BYD, Huayang, Chuanyi Technology and Vico Technology have already entered the sodium ion battery market, among which Contemporary Amperex Technology Co., Limited has made continuous technological breakthroughs.

However, at present, the electric vehicles on the market are basically lithium batteries, and a few high-end models are trying semi-solid batteries and solid batteries. Do we really need sodium ion batteries?

At present, there are two kinds of batteries commonly used in electric vehicles, namely lithium iron phosphate battery and ternary lithium battery. The main difference between these two batteries is that lithium iron phosphate battery has lower cost and higher safety, but its energy density is too low. Except BYD, other car companies basically only carry lithium iron phosphate batteries in low-end models.

The advantage of ternary lithium battery lies in its high energy density, while the disadvantage lies in its slightly higher risk and cost, and it is easier to deflagrate than lithium iron phosphate battery.

However, the theoretical energy density of ternary lithium battery will not exceed 500Wh/kg, and the energy density of 21700 battery introduced by Tesla can reach 300Wh/kg, which is the limit level of current power battery. According to the calculation of power consumption of 15 degrees per 100 kilometers, the battery weight of a car with a battery life of 1000 kilometers will be as high as 500kg or more.

The charging speed of electric vehicles is far less than that of fuel vehicles. Even if the number of charging piles is equal to that of fuel guns, it is more likely to cause congestion and queuing, so car owners generally have endurance anxiety. The battery life of domestic mainstream electric vehicles is usually 450 km ~650 km, which cannot solve the anxiety of car owners.

Therefore, many car companies and battery companies have been developing solid-state batteries. The lower limit of the energy density of solid-state batteries can almost be said to be the upper limit of the energy density of ternary lithium batteries. A casual search of relevant reports shows that the energy density of the solid-state battery jointly developed by Enli Power and Softbank Company is relatively low compared with other similar products, which can reach 300Wh/kg, while the energy density of the solid-state battery developed by NASA has reached an astonishing 500Wh/kg.

It seems that everything is beautiful, except the cost is slightly higher, but we may have overlooked a problem, whether it is lithium iron phosphate battery, ternary lithium battery or solid-state battery, it is inseparable from lithium.

According to the data of US Geological Survey (USGS), there are only about 98 million tons of lithium resources on the earth (data in 2022). Although half of the proven resources are in the hands of China enterprises, we must admit that this lithium mine resource is not enough to realize the electrification transformation of the global automobile industry. For this reason, Tesla will build its own lithium ore refining plant to improve the utilization rate of lithium ore resources.

The content of sodium ranks sixth, more than 400 times that of lithium. Rich in content and easy to mine, the cost of sodium ion battery is naturally much lower than that of lithium battery. For the sake of cost and environmental protection, sodium ion batteries are the best choice for low-cost and long battery life in low-end models.

In addition to low cost, sodium ion batteries have two advantages, that is, higher safety and better performance at low temperature. Even in the cold areas in the north, there is no need to worry that the winter temperature is too low and the battery life of electric vehicles will drop sharply.

Sodium ion battery seems to be the hope of realizing low cost and long battery life, but there is still a problem that sodium ion battery needs to solve, that is, the energy density is too low!

At the 15th Shenzhen International Battery Technology Exhibition in May this year, Tuobang released a sodium ion battery with an energy density of only 120Wh/kg, which is expected to increase to 160Wh/kg in 2025, even worse than lithium iron phosphate battery.

According to the data released by the second sodium ion battery industry chain and standard development forum held in July, the average energy density of the products evaluated by 17 sodium ion battery enterprises is only 104.1Wh/kg, which can be said to be terrible and not suitable for electric vehicles at all for the time being.

Contemporary Amperex Technology Co., Limited, the power battery company with the highest installed capacity in the world, invested heavily in the research and development of sodium ion batteries, and released the first generation of sodium ion batteries in 2021, with an energy density of 160Wh/kg. At the Shanghai Auto Show, companies such as Cherry and Chery announced that they would launch cars equipped with Contemporary Amperex Technology Co., Limited sodium ion batteries in the fourth quarter of this year, and the energy density of the second generation sodium ion batteries in Contemporary Amperex Technology Co., Limited could reach 200Wh/kg.

However, 200Wh/kg is obviously not enough to achieve 1000 km battery life and solve the anxiety of car owners. Similarly, according to the energy consumption of 15 degrees per 100 kilometers, the sodium ion battery pack with a battery life of 1000 kilometers weighs as high as 750kg. The weight of an ordinary B-class car is about 2000kg. If it is a medium-sized SUV, it is about 2500kg, and the proportion of batteries is too high.

Not only that, the battery also needs to occupy a lot of space. The energy density of the second generation sodium ion battery in Contemporary Amperex Technology Co., Limited is about 350Wh/L according to the volume, and the battery needs about 0.43 m space for 100 kilometers.

At present, some new energy vehicles adopt the skylight design because the bottom battery takes up too much space. If the traditional skylight design is adopted, the head space is likely to be too crowded. The dead weight of the battery will also affect the battery life. A car with too high weight needs a larger battery capacity to achieve the same battery life, occupying too much space and reducing the ride comfort.

The urgent task of sodium ion battery is still to improve the energy density, which is expected to reach 300Wh/kg, so that it is possible to achieve a long battery life of 1000 kilometers on ordinary models.

As far as the current situation is concerned, sodium ion batteries have the opportunity to gradually replace lithium iron phosphate batteries, and realize the tripartite confrontation with ternary lithium batteries and solid-state batteries in the future.

After the sodium ion battery is commercialized, the position of lithium iron phosphate battery will inevitably be very embarrassing, because the battery has the advantages of low cost and high safety, and all sodium ion batteries have it, and it performs better.

Chen Liquan, an academician of China Academy of Engineering, said that the cost of sodium ion batteries will be 20% lower than that of lithium iron phosphate batteries.

Xiaotong believes that in the future, the distribution of power batteries in the domestic automobile industry is likely to be dominated by sodium ion batteries, ternary lithium batteries and solid-state batteries.Among them, sodium ion batteries replace lithium iron phosphate batteries, which are mainly used in vehicles with less than 150,000 yuan, ternary lithium batteries are mainly used in high-end vehicles with 150,000 yuan to 350,000 yuan, and solid-state batteries are used in high-end vehicles with more than 350,000 yuan.

It should be noted that due to the influence of space and weight, sodium ion battery electric vehicles are unlikely to have a version with a battery life of 1000 kilometers, and the battery life is expected to be generally between 400 kilometers and 600 kilometers.

Ternary lithium batteries may have a small number of models with a battery life of 1000 kilometers, but the general battery life is expected to be 550 kilometers to 800 kilometers. The battery life of solid-state battery electric vehicles is likely to be more than 700 kilometers, and there are likely to be many models with a battery life of 1000 kilometers.

Of course, these predictions are all domestic cars, and the strategies of joint venture cars and domestic cars are different, so they don’t care so much about cost performance, so there may be some completely different results from domestic cars.

Hot search! Netizen: No wonder I am so sleepy.

Nehe city Rong media center

"I’m so sleepy recently.

I want to sleep when I have a little time. "

"Am I the only one who can’t sleep these two days?"

"Not only drowsiness but also eating, is this normal?"

……

these two days

Netizens frequently discuss their abnormal state.

Sleepiness, insomnia

Oversleeping at work and not wanting to go to school.

Everyone found out that it was always like this!

This is all because of geomagnetic storms?

↓↓↓ Click to review related reports ↓↓↓

Aurora appeared in Qiqihar, like "blush". "Does the magnetic storm have an impact on the human body?"

"Will magnetic storms affect sleep?"

It has become a topic of concern to many people.

The topic # geomagnetic storm sleepiness # was once boarded.

Weibo ranks first in the hot search list.

According to the China Meteorological Bureau

Bulletin of National Space Weather Monitoring and Early Warning Center

09: 16 Beijing time on March 23rd.

Solar flare activity

X-ray flux reached its maximum at 09: 33.

The peak intensity of flare is X1.1

According to analysis

It is expected that the earth will usher in a medium-to-earth magnetic storm.

According to the news of China Meteorological Bureau, there will be geomagnetic activity on March 24th, 25th and 26th, among which a moderate geomagnetic storm or even a geomagnetic storm may occur on March 25th, and it is expected that geomagnetic activity will last until March 26th.

Under this influence, the orbital height of the space station may decrease due to atmospheric drag, and the positioning error of satellite navigation equipment will increase, and aviation flight will face the dual risks of poor communication environment and trans-polar radiation. For the public, especially homing pigeon players and aurora lovers, we should always pay attention to space weather information in the next few days.

Source/CCTV News

Geomagnetic monitoring data show that from 23: 00 Beijing time on March 24th to 23: 00 on March 25th, there were 3-hour extra-large geomagnetic storms, 6-hour moderate geomagnetic storms and 3-hour small geomagnetic storms.

This is the same as that released on March 24.

The early warning results of geomagnetic storms are basically the same.

Under the strong bombardment of this energy from the sun, the earth’s magnetic field has undergone drastic short-term changes, accompanied by numerous collisions between the earth’s atmosphere and the high-energy particles of the sun, and the result is the formation of aurora.

Wu Rui, chief service officer of Shanghai Meteorological Bureau, told reporters that high-energy particles interfere with geomagnetic storms generated by the earth’s magnetic field, which has little impact on human health, but will have an impact on mobile phone signals, navigation, satellite TV and aviation. Huang Yu, a researcher at the Purple Mountain Observatory’s solar high-energy and related physical processes research group, also said that magnetic storms have little impact on human health.

    From left to right: Zhang Xin, Network Information Security Department of Telecommunications Administration of Ministry of Information Industry; Wang Lijian, Press Office of General Office of Ministry of Information Industry; Zhu Lu, Propaganda Department of Network Bureau of the State Council Press Office.


    The three activities are introduced respectively:


    1. "Cheer for Jiangmen-10,000 reasons why I love Wuyi" SMS solicitation activity.


    On October 8, 2006, the Sixth Plenary Session of the 16th CPC Central Committee was successfully held, and "studying and building a harmonious socialist society" was the main topic of the meeting. Social harmony will become the common aspiration of hundreds of millions of people. We believe that we should also do our best to build a harmonious society, and the best way is to give full play to the advantages of mobile communication at any time, anywhere and with us, carry forward the spirit of "great love" and preach excellent folk customs. So, in a short week, we planned to launch the "Cheer for Jiangmen-10,000 reasons why I love Wuyi" SMS MMS collection activity.


    The solicitation activity lasted for half a year and was divided into three stages:


    The first stage is the short message collection stage. Through active publicity, the company mobilized more than 2.5 million local customers of China Mobile to create healthy and uplifting short messages, without limiting the number of messages sent by each customer, and regularly arranged excellent short messages to be displayed in local mainstream media.


    The second stage is the short message audition stage. The company adopts the popular PK method, and the excellent SMS is selected by the public through SMS voting. The weekly award, monthly award, championship and other awards are all selected by the public. It can be said that our excellent short messages are "from the masses, to the masses".


    The third stage is the short message dissemination stage. The company will review and display the excellent short messages selected by the public, invite relevant experts to comment and summarize, and mobilize readers to disseminate excellent short messages. At the same time, the company also displays and publicizes short messages at bus stops in major streets of the city. By the end of the activity in March 2007, more than 80,000 customers had participated and 100,000 short messages had been collected. The activity received a warm social response. Under the extensive publicity of major media, "Cheering for Jiangmen" has become a beautiful cultural landscape, and "red jokes" have spread all over the hometown of overseas Chinese.


   Featured red paragraph works:


    "Ode to Jiangmen" shows Baishui Guifeng, and Yamen scolds Shi Xiong. China said that Jasper is more exquisite. The red joke "139 * * * 8777" was personally sent by Li Wei, our vice mayor in charge of science, education and culture in Jiangmen, which gave us great encouragement and support! Unfortunately, due to work reasons, Vice Mayor Li can’t be present today to share his creative experience with you.


    "Here are beautiful scenery, outstanding people and harmonious society. Ten years after I came here, I have fallen in love with this hot land! 134 * * * 2277 "is the first short message we collected. Its creator, Mr. Tan, came to Jiangmen from Guangxi more than ten years ago to start a business, and has regarded the hometown of overseas Chinese as his hometown. Our activities gave him a platform to express his thoughts, so he responded quickly.


    "Cheer for the New Eight Scenes in the Hometown of Overseas Chinese" East Lake is rippling with clear water, and birds of paradise attracts visitors. Goose Guifeng is nostalgic, and when Chuan Dao likes to fish. Diaolou beautiful scenery and garden paintings, fairyland hot springs looking for elegant poems. I can’t help loving my hometown, so don’t hesitate to applaud. (Note: the names of the new eight scenic spots are embedded in the poem) 135****1726 "The creator of this red paragraph is Mr. Lin Liang, an old friend of our company. Why do you say he is our old friend? Because from the very beginning of the activity, he paid close attention to us and gave us suggestions, suggestions and suggestions in various ways. What moved me in particular was that after sending the red paragraph, he was worried that we would not receive it in time, so he made a special trip to the company from Xinhui and personally delivered the red paragraph. The sincerity of the elderly not only moved us, but also made us realize that we should not only hold this activity, but also do it well!


    2. Seminar on "Jiangmen Contemporary Spirit"


    100,000 short messages triggered a heated discussion in the whole city. We quickly communicated with the Propaganda Department of the Municipal Party Committee and the Municipal Federation of Literary and Art Circles, and found that these 100,000 short messages reflected all aspects of Jiangmen people’s contemporary humanistic spirit and folk customs from different angles, which should be systematically discussed and summarized. So, on April 20, 2007, we held a grand seminar on "Jiangmen Contemporary Spirit". This is the first time to discuss Jiangmen spirit through such specific activities as "Cheering for Jiangmen" after Jiangmen’s reform and opening up.


    The seminar invited experts and scholars in history, sociology and mass communication to discuss the contemporary Jiangmen spirit displayed by people living in Wuyi area in the new fashion of contemporary harmonious society. The Jiangmen spirit, which is "inclusive, pragmatic, enterprising, sentimental and innovative", has once again inspired the spirit of unity and struggle of all the people in the hometown of overseas Chinese. Major local media have widely reported the activities in major time periods and major pages, and the social response has been very enthusiastic.


    3. Book publishing and new book release conference of "Wuyi Nine Chapters"


    The successful holding of the seminar "Jiangmen Contemporary Spirit" made the people in the hometown of overseas Chinese understand the deep meaning behind the short message "10,000 reasons why I love Wuyi". Inspired by the provincial company’s compilation of "Red Pieces" into a book, with the support of the municipal party committee and municipal government, we decided to select the excellent short messages of "Cheering for Jiangmen" into a book and named it "Wuyi Nine Chapters". "Nine Chapters of Wuyi" is divided into nine chapters, which include celebrities’ elegant traces, beautiful scenery, feelings of overseas Chinese in their hometown, and the new look of ancient cities. At the same time, it shows the folk customs such as dragon dance, three rivers, floating stones and singing songs in water towns.


    The book is prefaced by Mayor Wang Nanjian himself. In the editing process, we specially invited the Propaganda Minister and Vice Minister of the Municipal Party Committee and the Chairman of the Municipal Federation of Literary and Art Circles as general consultants, and invited professors from the Chinese Department, Philosophy Department and History Department of local universities and experts from the Municipal Federation of Literary and Art Circles as consultants, which integrated expert wisdom. As a tangible contribution to building a "famous cultural city" in cooperation with the municipal government, Wuyi Nine Chapters was praised by the Jiangmen Municipal Party Committee and Municipal Government as "a banner for building a" famous cultural city ",a business card for Jiangmen’s external publicity, and a picture showing folk customs", which was well received by the leaders of the National People’s Congress, the provincial party committee and the government at all levels in Jiangmen, and was recognized by international counterparts such as NTT DOCOMO in Japan.


    In addition, in the process of publishing the book, it coincides with the sprint stage of Kaiping Diaolou and villages applying for world cultural heritage. The Five Cities and Nine Chapters not only vividly shows Jiangmen’s historical background, folk customs and contemporary spirit with the handwriting of 100,000 people, but also guides healthy social public opinion by means of information technology, making contributions to the success of applying for the world heritage.


       4. Experience of "Cheer for Jiangmen" theme series of "Red Duanzi"


    The great success of the theme series of "Cheer for Jiangmen" can not be separated from the strong guidance and support of the Jiangmen Municipal Party Committee and Municipal Government, from the momentum promotion and spiritual inspiration of the "Red Piece" activities of provincial companies, and from the support and cooperation of the people in the hometown of overseas Chinese. In addition, Jiangmen Branch also summed up several experiences and insights:


    First, give full play to the advantages of mobility and fulfill corporate citizenship responsibilities.


    Jiangmen Branch of China Mobile Guangdong Company, as a leading communication enterprise in Jiangmen, has been actively exerting the advantages of "anytime, anywhere and with you", not only ensuring urban construction and optimizing investment environment with high-quality network and services, but also promoting the construction of "a famous cultural city" by means of informationization. The theme series of activities of "Cheer for Jiangmen" aims to achieve "zero distance" communication between citizens and the government by building an information platform for the public to communicate anytime and anywhere. We believe that excellent corporate citizens should bear such social responsibilities and make contributions to urban development and progress.


    The second is to carry forward the spirit of the times and help build a harmonious society.


    Building a harmonious society is the main theme of today’s times. On the one hand, the theme series of "Cheer for Jiangmen" mobilized the public to "talk about harmony" and "praise harmony", on the other hand, it "spread harmony" and "praise harmony" by downloading and forwarding short messages, which closely conforms to the spirit of the times and the will of the people.


    At the same time, young people are the future of the motherland. The "Cheer for Jiangmen" activity attracts young people to create and spread red jokes by themselves in the form of SMS and MMS, which are popular among young people. In the "Discover the Beauty of Diaolou" activity, more than 20,000 primary and secondary school students sang about Diaolou and praised their hometown, which promoted the innovation of youth education and helped to promote young people to establish a healthy and upward outlook on life and values.


    Third, combine the culture of the hometown of overseas Chinese and innovate the means of cultural propaganda.


    Wuyi, the hometown of overseas Chinese, has outstanding people and profound cultural heritage. The activity closely revolves around the spiritual culture and folk customs of the hometown of overseas Chinese, and at the same time, it grasps the characteristics of "rapid dissemination and real-time sharing" of online culture, innovates cultural propaganda means, occupies online culture with excellent cultural products, spreads the characteristic folk customs and humanistic feelings of the hometown of overseas Chinese, and dispels the discordant voices, which is warmly welcomed and positively responded by the public.


    Through this activity, Jiangmen Branch of China Mobile Guangdong Company deeply realized that network culture is an important part of socialist culture, and the innovation of network culture content and mechanism represented by "Red Duanzi" is a useful attempt and exploration to implement the spirit of promoting the great development and prosperity of socialist culture in the 17th National Congress. In the future work, Jiangmen Branch will continue to carry forward the good experience and good practices of this activity, cheering for urban homes, cheering for a better life and cheering for a harmonious society!
