　　Since the beginning of the year, the vast number of state-owned enterprises have made concerted efforts, worked hard and made firm progress on the road of high-quality development.

　　The General Secretary of the Supreme Leader pointed out: "We must unswervingly deepen the reform of state-owned enterprises, focus on innovating institutional mechanisms, speed up the establishment of a modern enterprise system, give play to the enthusiasm, initiative and creativity of all kinds of talents in state-owned enterprises, and stimulate the vitality of all kinds of elements."

　　Report to the 20th CPC National Congress of the Communist Party of China proposed to deepen the reform of state-owned assets and state-owned enterprises, speed up the layout optimization and structural adjustment of the state-owned economy, promote the state-owned capital and state-owned enterprises to become stronger, better and bigger, and enhance the core competitiveness of enterprises.

　　At present, the main objectives and tasks of the three-year reform of state-owned enterprises have been completed. "The twentieth Congress of the Communist Party of China has pointed out a new direction and made new arrangements for the reform and development of state-owned enterprises." Zhang Yuzhuo, secretary of the Party Committee and director of the State-owned Assets Supervision and Administration Commission of the State Council, said that the next step will be to consolidate and deepen the achievements of the three-year action, plan a new round of deepening the reform of state-owned enterprises, and push state-owned enterprises to make new and greater contributions to comprehensively promoting the great rejuvenation of the Chinese nation with Chinese modernization.

　　Improve the modern enterprise system with China characteristics and make state-owned enterprises operate more efficiently.

　　General Secretary of the Supreme Leader pointed out: "Upholding the Party’s leadership over state-owned enterprises is a major political principle and must be consistent; Establishing a modern enterprise system is the direction of state-owned enterprise reform and must be consistent. "

　　Since the launch of the three-year action, state-owned and state-owned enterprises have fully implemented the "two consistency", made great efforts to promote the strengthening of party leadership in improving corporate governance, and accelerated the improvement of modern corporate governance mechanisms.

　　— — Constantly strengthen the leading role of party committees (party groups) in "taking the direction, managing the overall situation and ensuring implementation".

　　Issue and implement the Opinions of Central Enterprises on Strengthening the Party’s Leadership in Improving Corporate Governance, and promote state-owned enterprises to comprehensively formulate the list of pre-research items … … In recent years, the leadership of the party in state-owned enterprises has been continuously strengthened, and the boundaries of powers and responsibilities of various governance subjects have become clearer.

Last year, its revenue increased by 16% year on year.

　　— — Give better play to the role of the board of directors in "setting strategy, making decisions and preventing risks".

　　On December 29th, 2022, the State Power Investment Corporation held a board meeting, which deliberated and adopted another major project investment decision. "The external directors held three meetings to study and went to the field for investigation. In response to the questions and suggestions of external directors, the management members answer questions and organize demonstrations; The chairman and the party group also fully respected the opinions and suspended the pre-research of the party group meeting before reaching a consensus. " Lu Chun, convener of external directors of State Power Investment Corporation, said. From 2020 to 2022, among the topics deliberated and adopted by the Board of Directors of State Power Investment Corporation, 15 were studied and discussed by external directors for many times, which effectively improved the ability of directors to exercise their duties.

　　Documents such as the working rules of the board of directors of central enterprises, the evaluation methods of the board of directors and directors have been issued, and 13,000 subsidiaries of central enterprises, 724 local-level enterprises and 25,000 local-level subsidiaries have established boards of directors. The board of directors should be fully completed and basically realize the majority of external directors … … A series of reforms have made the role of the board of directors as the main body of business decision-making more prominent.

　　— — Further guarantee the management’s responsibility of "seeking management, grasping implementation and strengthening management".

　　"The management team has the right to use, be motivated and secure, and the corporate governance structure operates efficiently." Li Guangqing, chairman of Shandong SDIC, said that last year, the company’s board of directors granted decision-making power to managers in 17 aspects, including project investment, asset disposal, and salary assessment of ownership enterprises, which provided better protection for managers to perform their duties.

　　At present, 97.4% of the subsidiaries of central enterprises and 98.2% of local state-owned enterprises have established management systems in which the board of directors authorizes managers.

　　The Central Economic Work Conference proposed that the modern corporate governance of state-owned enterprises with China characteristics should be improved and truly operated according to the market-oriented mechanism. The State-owned Assets Supervision and Administration Commission of the State Council stated that the next step is to strengthen the party’s leadership in improving corporate governance, improve the level of internal system construction based on the company’s articles of association, hierarchically classify and dynamically optimize the list of major business management issues in front of the party Committee (party group); We will continue to select excellent and strong external directors, accelerate the construction of a professional, responsible, standardized and efficient board of directors, and deepen the construction of the board of directors of subsidiaries.

　　Optimize the layout of the state-owned economy, and the state-owned enterprises are more powerful.

　　General Secretary of the Supreme Leader stressed: "Promote structural adjustment, innovative development and layout optimization, so that state-owned enterprises can play a leading role in the supply-side structural reform."

　　Guoneng Bio-restructuring, a leading enterprise in the field of biomass power generation in China, entered the State Power Investment Corporation, the medical institutions under China Power Construction Corporation joined the General Technology Group, and the Three Gorges Group transferred its hydropower company to CCCC … … At the beginning of the new year, the professional integration of central enterprises has continued. During the three-year operation, the overall layout structure of state-owned capital was optimized through a series of measures, such as restructuring and integration, creating a "chain length" of modern industrial chain, and promoting slimming and fitness.

　　On the one hand, the strategic supporting role of the state-owned economy is further highlighted.

　　Build leading enterprises such as shandong energy, Shandong Port and Shandong Expressway; Separate and integrate the health, cultural tourism and environmental protection sectors scattered in other enterprises, and form regional leading enterprises such as Shandong Health, Shandong Cultural Tourism and Shandong Environmental Protection … … In recent years, Shandong has actively promoted strategic restructuring in the fields of equipment manufacturing, coal and ports. "The layout of the state-owned economy is more optimized, and the quality and efficiency are further improved. Last year, the operating income of Shandong provincial enterprises increased by 51.4% compared with 2019." Man Shengang, Party Secretary and Director of Shandong SASAC, said. According to statistics, during the three-year operation, 347 provincial state-owned enterprises in 116 groups were reorganized and specialized integration was carried out 2150 times.

　　With regard to central enterprises, since the launch of the three-year action, the State Council State-owned Assets Supervision and Administration Commission has successively promoted the strategic reorganization of four groups of seven central enterprises, newly established and accepted eight central enterprises, including China Satellite Network and China Rare Earth, and promoted more than 30 specialized integration projects of central enterprises in the fields of electric power, inspection and medical care. At present, central enterprises account for more than 70% of the income in key areas of national security, national economy and people’s livelihood.

　　On the other hand, the advantages of state-owned enterprises in taking charge of their main business have been further enhanced.

　　In the early morning of January 29th, with the "Nansha Glory" unloading the whole ship of Brazilian iron ore in Rizhao Port, the cumulative cooperative freight volume between China Mining and Brazil’s Vale, which belongs to COSCO Shipping, exceeded 100 million tons. Operating income ranks first among global shipping companies, and it carries 1/10 of the world’s shipping trade volume with 1/18 of the world’s capacity. The total assets have historically exceeded one trillion yuan. By promoting internal integration, forming scale advantages and digging deep into synergies, COSCO Shipping’s comprehensive strength and global shipping market position have been further enhanced.

　　At the foot of the Mid-Levels in Hangzhou, the former "Shili Steel City" is now a hot spot for digital economy. Since the three-year operation, Hangzhou Iron and Steel Group has promoted the shutdown and transformation of Mid-Levels Iron and Steel Base, eliminated inferior industries in an orderly manner, and developed and expanded new industries through asset packaging, investment and mergers and acquisitions. "From deep cultivation of traditional manufacturing industries to participation in the digital economy, structural adjustment has enabled the Group to achieve a new leap. Last year, the revenue of strategic emerging industries increased by 56% year-on-year." Zhang Liming, chairman of Hangzhou Iron and Steel Group, said.

　　In 2022, central enterprises realized a total operating income of 39.4 trillion yuan, an increase of 8.3% year-on-year; In the first 11 months of 2022, local supervision of state-owned enterprises realized operating income of 33.7 trillion yuan, up 8.1% year-on-year & hellip; … With the deepening of reform, the competitiveness, innovation, control, influence and risk resistance of the state-owned economy have been continuously enhanced. A few days ago, the State-owned Assets Supervision and Administration Commission of the State Council issued a notice requesting central enterprises to further focus on their main business, develop the real economy, improve the quality of effective investment and promote a good start in the first quarter.

　　Improve the innovative market-oriented management mechanism, and the state-owned enterprises will be more energetic.

　　General Secretary of the Supreme Leader pointed out: "State-owned enterprises should deepen reform and innovation and strive to build modern enterprises".

　　Since the launch of the three-year action, three system reforms have broken the ice in an all-round way, and a new type of management responsibility system with the tenure system and contractual management as the core has been basically established.

　　— — Moving away from the "iron chair", managers can go up and down.

　　All the management members of the 1471-seat enterprise signed the annual/term operating performance responsibility letter; Refine 18 specific implementation measures, put forward the goal of struggle, and clearly stipulate 7 kinds of exit situations … … Not long ago, in 2022, the "Assessment List" of COSCO Shipping Managers was announced, and the proportion of final adjustment and incompetent withdrawal reached 6.93%.

　　Capable people go up, mediocre people go down. At present, the proportion of central enterprises and local sub-enterprises at all levels that carry out the tenure system and contractual management of managers has increased to over 99.6%, covering 84,000 enterprises with a total of 220,000 people. By the end of November 2022, the proportion of managers of central enterprises and local state-owned enterprises competing for posts reached 57% and 56.3% respectively.

　　— — Break the "iron rice bowl" and employees can get in and out.

　　Anhui provincial enterprises have fully implemented open recruitment, and in the past three years, they have hired 41,400 people of various types; Chinalco Group finds out the way for the surplus staff through job-transfer training and cross-enterprise transfer and resettlement … … Through the reform, the proportion of open recruitment of new employees in central enterprises and local state-owned enterprises has risen to over 99.9%.

　　— — If you don’t engage in "big pot rice", your income can increase and decrease.

　　Performance is linked to electricity, and posts are determined by performance. In Jidian Distribution Power Company under the State Power Investment Corporation, among the power market development and marketing teams formed by more than 30 employees, each of them signed a market-oriented salary agreement, and the enthusiasm of employees was further enhanced.

　　We will continue to promote the reform of the wage determination mechanism of state-owned enterprises, flexibly use medium and long-term incentive measures such as equity incentive, dividend incentive, excess profit sharing, virtual equity, and follow-up investment, and continuously optimize the market-oriented salary distribution mechanism of state-owned enterprises. At present, the proportion of qualified central enterprises and subsidiaries of local state-owned enterprises that have carried out medium and long-term incentives has reached 94% and 88.8% respectively, benefiting 491,000 key employees.

　　The relevant person in charge of the State-owned Assets Supervision and Administration Commission of the State Council said that the next step will be to continuously deepen the reform of the three systems, fully implement the "three-energy" mechanism, push forward the examination and evaluation of reform in a normal way, and create a model of 100 households’ reform by classification.

The challenging plateau extreme environment is the most rigorous testing ground for off-road vehicles. As a representative of off-road field, Toyota Land Cruiser is famous for its long history and strong off-road ability, and is deeply loved by senior off-road players. As a new cross-country species, Dongfeng Warrior 917 not only inherits the cross-country genes of military warriors, but also incorporates intelligent electric technology, successfully opening the luxury road of hard-line cross-country. On the plateau, who is better between the two? Only after the comparison will we know!

Power system competition, whose performance is stronger?

In the off-road field, Toyota Land Cruiser has always been known for its powerful performance and reliability. It is equipped with a 4.0L V6 naturally aspirated engine with a torque of 385 Nm. However, in the plateau area, this car has encountered obvious challenges. Due to the high altitude, thin air and low air pressure in the plateau area, the engine intake of Land Cruiser is significantly reduced and the fuel combustion is insufficient. This directly led to a sharp decline in its dynamic performance, and the original strong power became soft and weak on the plateau.

In contrast, Dongfeng Warrior 917 provides more diversified power options, including pure electric version and extended range version. The pure electric version adopts a four-motor four-wheel drive system, with a horsepower reserve of up to 1088Ps, and the acceleration time of zero hundred is only 4.2 seconds, which can maintain strong power output even in the plateau environment. The extended-range model is equipped with three motors and a 1.5T range extender, with a horsepower of 816 horsepower and a CLTC comprehensive cruising range of 1,026 kilometers. Because the range extender is not directly involved in driving, the power is slightly affected by the altitude change, providing stable and sufficient power in the plateau area.

Who can provide more comfortable driving experience in suspension system competition?

Suspension system plays an important role in vehicle performance, comfort and passability. The rear axle of Toyota Land Cruiser adopts dependent suspension (integral bridge type). Although this structure can provide better bearing capacity and passability under complex road conditions, when driving at high speed under continuous potholes, the overall bumpiness of the vehicle is relatively strong, which affects the ride comfort.

Dongfeng Warrior 917 is equipped with AeroRide multi-stage intelligent adjustable air suspension from BWI Jingxi, equipped with 5-speed adjustment, supporting 150mm long-stroke suspension height adjustment, supporting 45mm downward adjustment and 105mm upward adjustment, which can realize multi-body attitude adjustment, support body height adjustment, body height maintenance, easy loading, suspension welcome function, and take into account multiple requirements of off-road, fuel economy and convenience of boarding and descending. The maximum ground clearance of 335mm can be reached in the extrication mode, which brings strong road trafficability.

Steering system competition, who can bring better handling?

Today, with the continuous innovation of automobile technology, the performance of steering system directly affects the driving experience of vehicles. The R-EPS electric power steering system adopted by Dongfeng Warrior 917 has higher steering efficiency than the common EPS system of ordinary off-road vehicles. At the same time, the R-EPS electric power steering system has stronger axial load capacity. This makes the steering system of Dongfeng Warrior 917 work stably and maintain good handling performance when it bears a large load and impact, which provides a strong guarantee for the reliability and safety of the vehicle.

In sharp contrast, the traditional hydraulic power steering system adopted by Toyota Land Cruiser. Due to the characteristics of its mechanical structure, it may increase the driver’s driving fatigue when driving for a long time or needing frequent steering operations. More crucially, in the plateau environment, the hydraulic power steering system is facing severe challenges, and hydraulic oil pipes and other components are prone to air resistance, which will directly affect the working performance of the system, resulting in slow and inaccurate steering response, and may even endanger driving safety in severe cases.

Brake system competition, braking can only play wild.

Toyota Land Cruiser is equipped with mechanical hydraulic braking system, which is famous for its stable and reliable braking torque. However, in this special environment of plateau area, due to high altitude and large temperature difference between day and night, these extreme conditions put forward a severe test for the performance of hydraulic oil. In low temperature environment, the fluidity of hydraulic oil becomes worse, which may lead to the slow response speed of the braking system, thus affecting the braking effect; However, at high temperature, the hydraulic oil pipe is prone to air resistance, which further reduces the braking efficiency. These problems not only affect the driving comfort, but also affect the driving safety to some extent.

Facing the challenge of plateau environment, Dongfeng Warrior 917 adopted a more advanced IBC hydraulic brake-by-wire system. This innovative technology directly controls the braking system through electronic signals, and accurately controls the flow and pressure of hydraulic oil, thus achieving accurate control of braking force, which significantly improves the braking effect and safety. Compared with the mechanical hydraulic braking system, the brake-by-wire system has faster response speed and higher sensitivity, and can respond to the driver’s braking instructions more timely.

Who is the more reliable travel companion in the security competition?

In the automotive field, safety has always been one of the core elements that consumers are most concerned about. Toyota Land Cruiser adopts TNGA architecture, the body is welded by laser, and the frame is mainly made of high-strength steel. This kind of steel has excellent tensile strength and yield strength, which can effectively absorb and disperse energy during collision and protect the safety of occupants in the car. In addition, the key parts of the car body, such as A-pillar, front pillar and roof beam, are reinforced with multi-layer structure and high-strength steel plate to further improve the rigidity and anti-collision ability of the car body.

Dongfeng Warrior 917, as a luxury electric off-road vehicle, adopts the technology of ultra-high-strength internal high-pressure integrated molding of longitudinal beam pioneered by non-loaded off-road vehicle in China, and uses high-pressure water medium to close the cavity for expansion, which can make the longitudinal beam stable in size, without weld, welding scale and welding slag, and welding thermal deformation. Due to the cold work hardening effect of expansion, the strength of parts is improved by 10% compared with the strength of materials. The frame structure is made of high-strength materials, and the coverage rate of high-strength materials from 600~800Mpa to 800 MPa is more than or equal to 85%. The high coverage rate ensures the strong and durable performance of the car body and ensures superior passive safety protection.

Four-wheel drive system competition, who has stronger ability to get rid of difficulties?

As we all know, the ability to get out of trouble is one of the core indexes for verifying off-road vehicles. As an evergreen tree in off-road field, Toyota Land Cruiser’s full-time four-wheel drive system has always been its proud capital, and it has won the favor of many consumers with its excellent comfort, stability and long-distance crossing ability. However, the domestic version of the Land Patrol lacks the front and rear differential locks in the four-wheel drive configuration, which makes it slightly inadequate in the face of extreme off-road conditions.

In contrast, Dongfeng Warrior 917 is equipped with electronically controlled mechanical differential lock and central virtual differential lock, which can achieve 100% mechanical locking, which not only improves the efficiency of torque transfer, but also ensures the stability and passability of the vehicle under extreme conditions. This configuration allows the Warrior 917 to face all kinds of complex terrain with ease and easily challenge extreme off-road conditions.

At the same time, Dongfeng Warrior 917 is the only vehicle in China that has passed the durability test of "National Military Standard" (GJB). After four rounds of military standard durability test, the total mileage exceeds 1 million kilometers, and the actual mileage of equivalent users is nearly 6 million kilometers, covering 99.5% of user usage scenarios. Among them, off-road working conditions, mountainous areas, mining areas and other extreme working conditions account for as much as 50%, ensuring that vehicles can maintain reliable operation under any circumstances, showing excellent reliability and durability.

With the continuous progress of science and technology, the automobile industry is undergoing changes. Dongfeng Warrior 917 has become a new dark horse in the off-road field with its advanced technology configuration and excellent performance, and has also set a new benchmark for domestic off-road vehicles. Traditional fuel off-road vehicles, such as Toyota Land Cruiser, may also need continuous innovation in technology to cope with the ever-changing market demand and environmental challenges.

　(Reporter Shu Xiaotong from the News Center of Central Radio and Television General Station, Ya ‘an, Sichuan Province) Spring is warm and sunny, and when the flowers are in full bloom in Buzhoushan, the Central Radio and Television General Station led a team to go to Ya ‘an with Guangdong Jiushun Holding Group and Zhongzhu Holding Co., Ltd. to hold a discussion on the big data intelligent cultural tourism project of "the ancient ruins of Buzhoushan", and to inspect the industry and big data industrial chain of the Economic Development Zone that has developed rapidly in Ya ‘an in recent years.

Yang Zongting, founder and chairman of the big data intelligent cultural tourism project of "Ancient Relics of Buzhoushan", introduced that more and more scholars and experts came to visit Buzhoushan, including China Academy of Sciences, China Academy of Social Sciences, National Astronomical Observatory, Central Party School, National Development and Reform Commission, Cambridge University, Columbia University, Stanford University, Washington University, etc., and CCTV News Center, Documentary Center and Central News Recording Film Studio also sent people to inspect and shoot. With the excavation of Sanxingdui cultural relics, more and more scholars believe that Kunlun Mountain and Buzhou Mountain are located in Ya ‘an, and Ya ‘an, Buzhou Mountain and Kunlun Mountain have become hot spots of public opinion.

Yang Zongting accompanied the executives of CCTV, Guangdong Jiushun Holdings Co., Ltd. and Zhongzhu Holdings Co., Ltd. to inspect Buzhoushan.

Zuo Yongzhong, president of Guangdong Jiushun Holdings Co., Ltd. introduced that "the ancient ruins of Buzhoushan" is a typical big data intelligent cultural tourism project, which is blank in China. Why do we choose Ya ‘an? Because Ya ‘an has excellent geographical environment and outstanding location advantages. It is 120 kilometers away from Chengdu and 115 kilometers away from Leshan, belonging to Chengdu’s "one-hour economic life circle". The project of "Ancient Relics of Buzhoushan" is located in Ya ‘an City, surrounded by Qingyi River in the west, north and east, and Zhougong River in the southwest, with Gongga Mountain in the west and Xiling Snow Mountain in the north. The vegetation on the mountain is good, the forest coverage rate is as high as 80% or more, and the clear spring gurgles all year round. The climate resources are superior, the air is fresh, and the maximum number of negative oxygen ions per cubic centimeter can reach 65830. Combined with the development of big data intelligent cultural tourism project, it will create a unique and original scenic spot with the theme of mountains and seas.

Geographically, Ya ‘an is a transitional zone between Sichuan Basin and Qinghai-Tibet Plateau. From a cultural point of view, Ya ‘an is a transitional zone between Han culture and Qiang and Tibetan culture. From the ecological point of view, Ya ‘an is a transitional zone between the central city and the natural ecological zone. In the past, Ya ‘an was the starting point of the ancient tea-horse road and an important node of the South Silk Road. Now, Ya ‘an has become an important intersection of the Sichuan-Tibet gateway transportation and logistics hub, the Chengdu-Chengdu Cultural Tourism Economic Belt, the Panxi Cultural Tourism Economic Belt and the Northwest Sichuan Cultural Tourism Economic Belt. Such a unique location advantage has greatly enhanced and broadened the development advantages of the big data intelligent cultural tourism project of "the ancient ruins of Buzhoushan". Especially after the high-speed railway from Chengdu to Lhasa is opened to traffic, Ya ‘an will surely become the first choice for buying houses, living, leisure and vacation, and health care in different places in Kangzang area.

Signing ceremony for development and investment of big data intelligent cultural tourism project of "the ancient ruins of Buzhoushan"

Yang Zongting, the initiator of the project, said that Zhougong Mountain was called Buzhoushan in ancient times, and it was recorded in the ancient Chinese historical document "Shan Hai Jing". Later, it became famous all over the world because Gong Gong was angry and could not touch Zhoushan. The "Dragon Cave" historical site recorded in China’s ancient geographical history "Taiping Universe" is located in the project area, which is the first of the eight scenic spots in Ya ‘an. There is Tianchi Lake at the top of Buzhou Mountain, which is called "Longhu Lake" by local people. There are many cliff inscriptions, eight diagrams stones, stone temples, stone beasts, stone squares and other relics in many places in the mountain. There is also an ancient scene of Longdong stone blooming on the mountain. Broken stone tablets and broken walls can be seen everywhere, with a strong historical and cultural atmosphere.

There are 5,000 mu of rest flower trees belonging to the rest family in Buzhou Mountain, and 3,000 mu in the scenic area, which were mistaken for wild jasmine by local people. The British Museum and the Royal Academy of Sciences have visited the country, and the conclusion is that the ancestral mountain of benzoin in ancient Persia spread to Persia and the whole Arabian Peninsula through the ancient Silk Road in Maiping six thousand years ago, and it grew and became a spice base for supplying the whole world. Nanshan, the president of the World Haiku Art Association, wrote "The Inscription of the Mountain of Not Being Surrounded" for the "Ancient Ruins of Not Being Surrounded", which wrote: The flower of Rest was born and raised in Sri Lanka 80,000 years ago, and the annual credit is granted in April, and the term lasts for a long time. Long-lasting fragrance, left a name in the world. Damascus, Persia, ruled the world in the Middle East, and benzoin was called the king, whose roots were traced back to Zhihu. Well, the ancestral court of benzoin incense should be inscribed with stones, so as to return the fragrance to elegance.

The ancestral hall of benzoin-the beautiful rest flower of Buzhou Mountain

Buzhou Mountain is called Shenshan Mountain, and there are still some ancient prehistoric plants such as Jin Sinan, Rest Flower, Emei Michelia, Dove Flower (Davidia involucrata), Taxus chinensis and Alsophila spinulosa. Jin Sinan, known as "Shenmu", has the functions of exorcising evil spirits, calming the nerves, expelling insects and exorcising evil spirits. It has been dedicated tribute wood for the imperial palace in past dynasties. There are countless existing animals and plants in Buzhou Mountain, such as God beast, God water, God fruit, God flower, God fish and so on. There are tens of thousands of rest flowers, yew, Jin Sinan, Emei smiling face and Davidia involucrata trees in the scenic spot. Besides, it is rich in natural green agricultural products, such as Mongolian Camellia, Tibetan tea, Tricholoma matsutake, mushrooms, yayu, yellow tangerine, loquat, cherry, bacon, jar meat, grass chicken, Duke of Zhou duck, yellow beef and so on.

Executives from Guangdong Jiushun Holdings Co., Ltd. and Zhongzhu Holdings Co., Ltd. visited Zhonghengtian SUV Automobile Factory.

Yang Zongting, the founder of Ya ‘an’s "Ancient Relics of Buzhoushan" project, loves collecting. Many of the cultural relics he collected in the local area over the past decades have attracted the amazement of experts and sinologists from Cambridge University in Britain, Harvard University in the United States and Columbia University, and some of them are even national treasures, such as the Yiji astrolabe of Buzhoushan, the remnant tablet of Buzhoushan and jade books. These discoveries have raised the importance of Buzhoushan to a higher position than Sanxingdui.

Join forces, Zuo Yongzhong and Yang Zongting shake hands in "the ancient ruins of Buzhoushan".

The folk song says, "Without Xi Wenju, there is no Bifeng Gorge". Known as the "Father of Bifengxia", Xi Wenju is also the president of China Metropolis Daily Research Association, the vice president of the World Chinese Newspaper Association, and the founder and president of Huaxi Dushi Bao. Xi Wenju thinks it is a great pity that Buzhoushan has such a good historical origin, such good natural science resources, and even the roots of Yijing and Taiji appeared here thousands of years ago, but Buzhoushan is idle in Ya ‘an. If the Bifengxia model is a bomb, then Buzhoushan is an atomic bomb! Recommended by CCTV, President Zuo Yongzhong specially hired Xi Wenju as the general consultant of the big data intelligent cultural tourism project of "the ancient ruins of Buzhoushan".

Six wonders of the mountain: one is easy to change, the other is to rest in peace, the third is the sea of clouds, the fourth is the mountain spring, the fifth is the Buddha lamp, and the sixth is Gongga.

Zuo Yongzhong, president of Guangdong Jiushun Holdings Co., Ltd. said, "Bifeng Gorge is characterized by the natural landscape environment and private capital entering the tourism development, while Buzhou Mountain is a superb embodiment of the scientific and technological level and cultural self-confidence of the ancient Shu people 5,000 years ago, and it has real objects. This is the pioneer of human scientific and technological development, and its scientific and technological achievements stand in the forefront of all mankind, spanning 5,000 years. From the perspective of civilization, this is the forerunner of guiding human civilization, which is a super bright spot and even more distinctive than Sanxingdui. What really attracts people is to restore the mythical environment of Buzhoushan, let people enter the mythical world to experience enlightenment and reproduce the grand occasion of Shanhaijing civilization, which will become a unique tourist landmark in the development of China cultural tourism in the future. "

Yang Zongting accompanied the executives of CCTV, Guangdong Jiushun Holdings Co., Ltd. and Zhongzhu Holdings Co., Ltd. to inspect Buzhoushan.

The most important thing about the big data intelligent cultural tourism project of "the ancient ruins of Buzhoushan" is the opportunity advantage. Sanxingdui, the splendor of the ancient Shu kingdom, has made the world know China again, and know Buzhoushan again. Shanhaijing and Shanhaijing culture are getting hotter and hotter, which brings excellent business opportunities to the Buzhoushan project. Twenty years ago, Ya ‘an was famous for Bifeng Gorge, which became the model of western development and the engine of China tourism development. The successive appearance of these advantages has provided a profound cultural support system for the recreation industry of Wenlv, an ancient country with ancient ruins of Buzhoushan Mountain with mysterious cultural background of mountains and seas, and also created unprecedented development opportunities for the recreation industry. As a national demonstration city of forest tourism, Ya ‘an has been focusing on the benchmark positioning of "Lung of Abundance and Ecological Ya ‘an" in recent years, and is making great efforts to build a medical highland in western Sichuan. The launch and implementation of the big data intelligent recreation and holiday project of "Ancient Country with Ancient Relics of Buzhoushan" in Ya ‘an can be described as a golden opportunity.

Chairman Yang Zongting introduced that the infrastructure construction of the "Old Country with Ancient Relics of Buzhoushan" project is basically available, and the 15-kilometer scenic highway has been opened for operation; The planned 20 km tourist trail, 5 viewing platforms, 12 leisure pavilions and promenades are also under construction. Every weekend and holiday, the mountain is overcrowded, and the demand for catering and accommodation is in short supply. The scenic spot urgently needs to be expanded to meet the sightseeing needs of tourists.

With the cultural relics unearthed in Sanxingdui shaking the world, people pay attention to the mysterious ancient Shu country. It turns out that many stories recorded in the Classic of Mountains and Seas took place in Ya ‘an, especially the mythical figures such as Gong Gong, Zhuan Xu, Nuwa and Dayu all lived here. In addition, from the aspects of humanity, geography, landform, vegetation, animals and so on, it is consistent with the content described by Shan Hai Jing.

In Ya ‘an City, which is close to "the ancient ruins of Buzhoushan", the inspection representatives took a group photo.

"Ya ‘an Buzhoushan Ancient Relics Country" big data intelligent cultural tourism project is led by Yang Zongting and initiated by CCTV. Together with Guangdong Jiushun Holding Group Co., Ltd., it invests 3 billion yuan to jointly build a brand-new big data intelligent cultural tourism industry demonstration zone in Ya ‘an, which does not integrate Zhoushan mysterious cultural carnival, exhibition of Shanhaijing relics, cultural tourism and medical care. Three scenic spots, Zhuan Xu Valley, Nuwa Palace and Gonggong Tribe, are planned and designed for the project. These ancient buildings provide visitors with the magical landscape of primitive ancient Shu culture, and are entertaining around the fairy tale that Gonggong fought against Zhuan Xu and was angry with Gonggong, which forms the core scenic spot of the project theme.

The scenic spot of "the ancient ruins of Buzhoushan" also includes scenic spots and sightseeing routes such as Buzhoushan Shenshan Kangyang Sanatorium, Shanhaijing Creation Resort (seven-star), the annual Ya ‘an Buzhoushan Mystery Culture Carnival (cum Shanhaijing Culture Week), Buzhoushan Yiji Museum, National Western Landmark Observatory, Shanhaijing Museum, Shanhaijing Immersed Cultural Performance Center, etc. There are float parades and immersive performances of Shan Hai Jing in the three major theme scenic spots of "Ancient Relics of Buzhou Mountain", and visitors can intuitively see the scenes of Nu Wa, Zhuan Xu, Gonggong and tourists having fun together.

Zuo Yongzhong, president of Guangdong Jiushun Holdings Co., Ltd. said, "The Bifengxia model in Ya ‘an was born 20 years ago, and the world shook. Today’s Shanhaijing Theme Big Data Intelligent Travel Project will once again become the landmark of Ya ‘an online celebrity. ‘ The ancient ruins of buzhoushan ’ The Big Data Intelligent Recreation Project is a unique idea. Combining with the landform of the hills and seas described by the mountains and seas thousands of years ago, it will create a scenic spot with the theme culture of the mountains and seas as the main theme, and provide a unique theme park for the people of the whole country. This project will become a tourist landmark in Sichuan Province and a major tourist destination IP in China facing the ancient cultural theme of overseas tourists. The fundamental difference between this idea and the Bifengxia model is that it is full of mysterious cultural impacts and eyeball effects in addition to natural landscapes, bringing fresh tourist blood and a world-famous industrial chain of mountains and seas to Ya ‘an City, which is about to rise rapidly, and bringing a new wind to the cultural tourism industry in Sichuan Province. "

Sanxingdui culture has been popular all over the world, and there is a physical ancient cultural park in Ya ‘an-"the ancient ruins of Buzhoushan", which makes Ya ‘an rise against the trend and reproduces the tourism madness of Bifengxia mode 20 years ago. At this once-in-a-lifetime historical opportunity, the big data intelligent travel project of "the ancient ruins of Buzhoushan" landed in Ya ‘an, which will greatly enrich Ya ‘an’s cultural literacy, improve its cultural genes, become a unique platform for the cultural industry of Buzhoushan, bind tourism, sightseeing, science and technology, big data and health care together, launch a complete intelligent industrial chain, occupy the highland of ancient culture, and create a leading model for the development direction of China’s ancient cultural industry and big data intelligent travel.

CCTV led a delegation with Guangdong Jiushun Holding Group to visit the Digital Planning Museum of Ya ‘an Economic Development Zone.

At the invitation of the Ya ‘an Municipal Government, the Ya ‘an Economic Investigation Group, led by the Central Radio and Television General Station and jointly composed of Guangdong Jiushun Holding Group and Zhongzhu Holding Co., Ltd., visited key parks such as Ya ‘an Economic Development Zone, Yayun and Sports Center, visited Zhonghengtian off-road vehicle automobile factory, digital planning hall of Ya ‘an Economic Development Zone and supporting facilities for Olympic sports events, and reached a strategic cooperation agreement with the Foreign Affairs Bureau of Ya ‘an Economic Cooperation Bureau. In the conference hall of Ya ‘an Municipal Government, leaders from Municipal Economic and Trade Cooperation Foreign Affairs Bureau, Yucheng Economic and Trade Cooperation Foreign Affairs Bureau, Yucheng Natural Resources and Planning Bureau, and Gaobao Village of Zhougongshan officiated at the ceremony. Guangdong Jiushun Holding Group and Ya ‘an Zhougongshan Tianbao Tourism Co., Ltd. signed an investment and development agreement, and Guangdong Jiushun Holding Group and Zhongzhu Holding Co., Ltd. decided to jointly invest 3 billion yuan to build and develop the big data intelligent cultural tourism project of "No Ancient Ruins of Zhoushan".

Zuo Yongzhong, president of Guangdong Jiushun Holdings Co., Ltd. believes that the big data intelligent cultural tourism project of "No Ancient Ruins of Zhoushan" will rewrite Ya ‘an’s tourism history and cultural history. Through the project of "No Ancient Ruins of Zhoushan", people will enter Ya ‘an, experience Ya ‘an and examine another Ya ‘an different from the previous one. In this historical stage of economic and technological spurt growth, integrating historical elements of ancient Shu culture such as Sanxingdui, Maiping, Jinsha and Baodun will collide to form a brand-new cultural storm, which will cause a cultural phenomenon and make Ya ‘an a brand-new world-class cultural tourism highlight.

Because of the appearance of Sanxingdui, people have a new understanding of Sichuan and ancient Shu. In particular, many mysterious things revealed by China’s ancient book Shan Hai Jing appear in Sichuan and Ya ‘an today, especially the academic voices of Wawu Mountain as Kunlun Mountain and Zhougong Mountain as Buzhou Mountain are frequent, which makes people further eager to enter Ya ‘an and Buzhou Mountain, and opens the curtain of revealing the culture of Shan Hai Jing.

　　Sina Auto News The second-generation Changan Yidong, which was listed at the end of March, must have left the deepest impression on everyone, which is the brand-new exterior design and the space practicality that has continued from the first-generation model. Yidong’s market vitality is very strong, and it has been firmly occupying an important market position in the independent A-class car camp for many years. In fact, there are not many independent models that can adhere to the complete life cycle and realize the replacement. For Changan, if the replacement of Yidong only stays in the face value and space, it seems a bit "strong outside and hollow inside". This time, we were lucky enough to come to Chang ‘an Automotive Engineering Research Institute to perform a major operation on the second generation Yidong to see what progress it has made compared with the first generation in terms of driving quality.

　　Important chassis parts of two generations of Yidong vehicles were put on the scene. Zou Yi, a senior automobile engineer in Chang ‘an, emphatically introduced the differences in suspension structure between the two generations of mobile vehicles.

　　Although they are all rear suspensions in the form of torsion beam, the second generation of escape rear suspension adopts U-O Forming closed torsion beam rear suspension from German suppliers, which is more difficult in process. The biggest feature of the new rear suspension is that it reduces the weight by 20% compared with the traditional V-shaped torsion beam on the basis of ensuring the structural strength. The reduction of unsprung weight has obvious benefits for vehicle handling performance.

　　The improvement in technology is perceptible. Touching the inner side of the cross beam of the two-generation mobile rear suspension, you will find that the inner surface of the first-generation runaway has obvious burr feeling, while the inner side of the second-generation vehicle is obviously smoother, which feels like the effect after a steel plate is bent and butted end to end.

　　Facing the domestic road conditions, the hidden danger of the rear suspension of many models is not the fracture of the cross beam, but the stress fatigue is easy to form between the transverse and longitudinal beams. The welding area between the second-generation escape rear suspension beam and the longitudinal beam has been increased, and the official introduction shows that its reliability has been improved by 380%.

　　There are also differences in the arrangement of rear suspension shock absorbers between the two generations. We see that the shock absorber of the first generation model is located in front of the shock absorber spring and has a short length; The shock absorber of the second generation model is located behind the spring and has a long length. The purpose of adopting this vertical arrangement is to improve the efficiency of isolating vibration. After all, a longer shock absorber can provide a larger compression stroke and more adjustment space, thus improving the comfort of the rear row. In fact, if you pay attention, you will find that many luxury brands C-class cars and D-class cars also use this "super-long" shock absorber and arrangement. At present, this layout method has been used in Focus, Lectra 01 and other models, and the next generation of GM models will be equipped. Independent brands have also been gradually adopted, and the second generation of Yidong is one of them.

　　In order to improve the comfort, engineers have also optimized the bushing structure of the second-generation runaway suspension, and appropriately reduced the stiffness of the bushing, which can improve the filtering ability of the suspension to road vibration and help to isolate the road from fine bumps.

　　Changan engineer also demonstrated the process of adjusting the shock absorber for us. Engineers will put the designed shock absorber prototype on the bench for testing, and the bench will compress/expand the shock absorber at different speeds of 0.05, 0.1, 0.3, 0.6 and 1.2m/s for four times to simulate the daily road conditions. In this process, the system will generate the damping data of the shock absorber to optimize the shock absorber repeatedly. We see that there are throttle plates with different sizes and shapes in the shock absorber, each with different specifications.

　　For example, there are 28 different schemes of throttle plate in the above picture, and its working state and deformation can affect the flow of damping oil, and then affect the performance of shock absorber. Although the shock absorber does not directly reflect the "soft and hard" parts of a car suspension, these small differences can determine the final driving experience of a car. In fact, few domestic independent brands can independently develop, test and adjust shock absorbers like Changan, and most of them directly send the requirements to suppliers for them to do.

　　After the chassis suspension is developed, the vehicle will be handed over to KC test bench to verify the suspension and steering motion characteristics. The cost of the test-bed is about 20 million yuan, which can quantitatively simulate the load and wheel state parameters of the suspension under various road conditions or body postures. It takes 2 days for each prototype to be put on the shelf, collect data, and then complete a set of tests, in which the collection time of complete KC data takes 4 hours. Of course, it is impossible for a car to go through KC test only once, and the comprehensive performance of the chassis system needs to be adjusted and verified repeatedly. This process is extremely cumbersome.

　　For front-drive vehicles, vehicles tend to understeer during intense driving. It is impossible for a car to have no understeer at all, and engineers can only minimize this trend. In the second generation, the toe-in gradient of the wheel was optimized, and the relative positions of the internal and external mounting points of the steering gear were modified, which can slow down the trend of understeer to a certain extent, and then improve the handling stability of the vehicle in corners.

　　Chang ‘an has his own thoughts on driving DNA. For example, in terms of steering transmission ratio, the second generation of escape has not only pursued the feeling of comfort. Compared with the first generation model, its steering line angular transmission ratio is reduced from 3 laps to 2.83 laps. Most cars and SUV models on the market need about 2.8~3 laps from left to right, and sports-oriented models will take about 2.5 laps. From the change of the transmission ratio of the second-generation freewheeling steering, we can also see that Chang ‘an is not satisfied with "good driving", but should work hard in the direction of "fun+good driving".

　　For the adjustment of EPS electric power steering carried by the second generation Yidong, Changan uses a set of "robot" system that can quantitatively control the steering wheel angle and speed, and measure the steering wheel torque and body roll angle in real time. Engineers will set up different test forms, such as sine input, sweeping and catching up, to test the roll degree of the vehicle, the response speed of the steering wheel and the reliability of the steering motor respectively. It is worth mentioning that the second generation of escape has improved the power of EPS steering assist motor, so that the ease of use and reliability of the vehicle in extreme handling are more guaranteed.

　　In addition to the steering transmission ratio just mentioned, the steering force feel is also an important item in EPS adjustment. Engineers showed us two different forces used in the test, namely, extremely light and heavy. During the test drive, you can really feel the different performances of the vehicle under two kinds of dynamics. In the extremely light mode, the steering feel of the vehicle is almost zero, and it begins to respond when it touches the vehicle lightly; In the heavier mode, the steering power is obviously reduced, and the arm will be tired when rubbing the car and turning around at low speed. The engineer said that the steering power directly affects the communication between a car and the driver, and it is not advisable for the steering wheel to be too light or too heavy. Therefore, EPS should be adjusted in combination with factors such as vehicle positioning and suspension calibration, so as to achieve stability and give people some driving pleasure.

　　In April this year, the second generation Yidong achieved a braking performance of 35.6 meters in a public test, which is known to friends who know a little about cars-similar to many luxury brand sports-oriented models. This time, Changan engineers analyzed some reasons behind this achievement for us.

　　In this pie chart, we can see that the braking performance of a car excludes environmental factors, and the factors related to the vehicle itself include axle load, calipers, body posture, tires, ABS and friction materials. The second generation of escape is mainly optimized for the thermal stability of the brake system and the formula of the brake shoe.

　　Through CAE simulation analysis, the influence of different caliper fluid requirements on pedal stroke is simulated, and then the thermal stability of brake disc at different temperatures is simulated. Simulation analysis can greatly improve the efficiency of research and development, so that engineers can take as few detours as possible.

　　Of course, only simulation analysis is not enough. Chang ‘an also has its own braking system laboratory. For example, this is where the brake pedal strength and master cylinder pressure are tested. Why are the brake pedals of some models "soft" at the initial stage, and it is necessary to step on the vehicle deeply before the braking force is obviously released? This is the key issue. Generally speaking, there is a certain gap between the pedal and the master cylinder pressure, that is, the empty position of the brake pedal, but excessive defecation in the empty position will delay the release of braking force and even cause safety hazards. Although the second-generation Yidong 35.6-meter 100-kilometer braking performance is not directly related to fine adjustment, we can also see from here that Changan’s control over the details of driving experience is quite in place.

　　In terms of braking materials, the second generation Yidong has optimized the formula compared with the previous generation. The main improvement aspect is to control the thermal decay of the brake as much as possible when it is above 500℃, and reduce the sensitivity of the brake to pressure and temperature. In other words, in the future, car owners can use the brake pedal to control the speed more confidently when they are driving downhill on a mountain road for a long time, and the vehicle is not easy to "stop" because the temperature of the brake system is too high.

　　In the past, independent brands were still making efforts in terms of large space and high configuration, striving to win the favor of consumers with low prices and high allocation. With the domestic auto market becoming more and more mature, the car buyers have a deeper understanding of cars, and improving the internal quality of vehicles has become a hard bone that manufacturers have to chew. Two generations of Yidong, the first generation of models gain a foothold with high cost performance, and the second generation of models will inevitably improve their driving quality. You really can’t just look at the configuration list when buying a car in the future. If you don’t get in the car and drive it, it’s hard for you to know its inner beauty.
