　　What are the highlights of the development of the eastern, central and western regions in the first three quarters? Which provinces have outperformed the national average in economic growth? Which provinces have faster consumption growth? Which provinces’ income levels have improved significantly? Recently, the statistical departments of 31 provinces, autonomous regions and municipalities have successively released the economic data of the first three quarters. Through this report card, we will find that China’s regional economic development is more coordinated and pays more attention to high-quality development.

　　You chase after me, and the economy is resilient enough.

　　In the first three quarters, which province had the fastest GDP growth? It is Hubei.

　　As the province most affected by the epidemic last year, Hubei recovered rapidly — — In the first three quarters, the GDP of Hubei was 3,473.156 billion yuan, ranking seventh among 31 provinces, ranking first with an increase of 18.7% compared with the same period of last year, and an increase of 6.4% compared with the same period of 2019, which was 1.3 and 5.0 percentage points faster than the first half and the first quarter respectively.

　　This steaming momentum is felt most deeply by local residents. Xu Pengcheng, a 29-year-old young man from Hubei Province, didn’t go to Guangzhou to work as usual this year. Instead, he ran a shop in Wuhan in partnership with his friends, ready to do a big job in the catering industry. "The passenger flow of various business districts and pedestrian streets in Wuhan has basically returned to the level before the epidemic. The overall situation is good, and we are particularly confident in the business prospects. "

　　Not only is the growth rate fast, but the new kinetic energy of Hubei’s economic development is strong, and the resilience of recovery and development is full. In the first three quarters, the added value of high-tech manufacturing in Hubei increased by 34.9% year-on-year. In the first three quarters, there were 19,475 construction projects in the province, an increase of 4,860.

　　Which provinces have a high total? Guangdong and Jiangsu rank in the top two, and their regional GDP both exceeds 8 trillion yuan. Among them, Guangdong reached 8.80 trillion yuan, Jiangsu 8.49 trillion yuan, and it is expected that they will all cross 10 trillion yuan in the whole year.

　　It is worth mentioning that the economic structure of various places has been further optimized. The added value of the tertiary industry in Guangdong and Jiangsu both exceeded 4 trillion yuan. The added value of tertiary industry in most provinces is higher than that of primary and secondary industries, and the tertiary industry in 23 provinces accounts for more than 50%, especially in Beijing and Shanghai, accounting for more than 70%, reaching the level of developed countries.

　　Observing the eastern, central and western regions, the performance of the central region was eye-catching in the first three quarters. In the first three quarters, among the 10 provinces whose GDP growth rate was higher than the national average, Hubei, Shanxi, Jiangxi and Anhui were all central provinces. Su Jian, director of Peking University National Economic Research Center, said in an interview with this reporter: "From the data of the first three quarters, a good situation of competing development has been formed among the central provinces. With the in-depth implementation of the strategy of the rise of central China, urban agglomerations in the middle reaches of the Yangtze River ‘ Bao Tuan ’ Development and high-quality co-construction ‘ Belt and Road ’ Driven by this, the central provinces have achieved ‘ Double promotion ’ 。”

　　Su Jian said that through the report cards of various provinces, it can be found that although the economic growth rate in the third quarter was affected by many factors, such as epidemic situation, flood and high base in the previous year, China’s economic strength, resilience and vitality remained unchanged. "All provinces have made great efforts to promote high-quality economic growth based on their own industrial structure and location advantages, and achieved good results. The regional economy is more balanced and coordinated, effectively responding to the tests of epidemic situation and public opinion. "

　　Income and consumption, the central and western regions accelerate to catch up.

　　"During the National Day holiday this year, many friends came to Xinjiang to travel." Zhang Junhui, a young man from Xinjiang, and his friends opened a folk shop in Grand Bazaar, Urumqi. On the shelves in the store, from Hetian jade to Badanmu, from Tianshan Snow Lotus to Dongbulaqin, all kinds of goods are dazzling. Benefiting from the continuous recovery of domestic consumer demand and the booming local holiday tourism, business in Zhang Junhui is good.

　　The simultaneous increase of residents’ income and consumption expenditure is the main feature of local economic recovery and growth.

　　In terms of income, the per capita disposable income of the national residents in the first three quarters reached 26,265 yuan, a nominal increase of 10.4% over the same period of last year; After deducting the influence of price factors, the real growth rate was 9.7%, which was basically in sync with GDP growth.

　　Among them, the per capita disposable income of residents in nine eastern provinces, including Shanghai, Beijing, Zhejiang, Tianjin, Jiangsu, Guangdong, Fujian, Shandong and Liaoning, continues to lead 31 provinces, which is higher than the national average. At the same time, the central and western provinces showed outstanding performance in the year-on-year growth rate of income. The nominal growth rate of per capita disposable income of residents in 13 provinces, including Tibet, is higher than the national average. Tibet, Hubei, Yunnan and Anhui in the top five are all central and western provinces, among which Tibet’s growth rate is as high as 15.27%.

　　Combing the income data of residents in recent years, we will find that the per capita disposable income of the central and western provinces has maintained a rapid growth rate. Among them, the growth rate of per capita disposable income in Tibet, Guizhou, Anhui, Sichuan, Yunnan, Chongqing and Jiangxi provinces in the first three quarters of the past three years exceeded the national average. According to experts’ analysis, on the one hand, this is related to the low per capita disposable income base in the central and western provinces, on the other hand, it is also the result of the state’s increased transfer payment to the central and western regions, the effective connection between the consolidation and expansion of poverty alleviation achievements and rural revitalization, and the implementation of relevant regional development strategies.

　　The income of rural residents grew faster than that of urban residents, and the relative income gap between urban and rural residents continued to narrow. In the first three quarters, the per capita disposable income of urban residents was 35,946 yuan, a real increase of 8.7% after deducting the price factor; The per capita disposable income of rural residents was 13,726 yuan, a real increase of 11.2% after deducting the price factor. The actual growth rate of per capita disposable income of rural residents is 2.5 percentage points faster than that of urban residents.

　　Looking at consumption again, in the first three quarters, the per capita consumption expenditure of the national residents reached 17,275 yuan, a nominal increase of 15.8% on the basis of a decrease of 3.5% in the same period of last year; After deducting the price factor, the actual increase was 15.1%.

　　Regionally, the eastern provinces have a higher level of consumer expenditure. The data shows that in the first three quarters, the per capita consumption expenditure of eight provinces, including Shanghai, Beijing, Zhejiang, Tianjin, Guangdong, Jiangsu, Fujian and Chongqing, exceeded the national average, and the above provinces were all eastern provinces except Chongqing.

　　However, the central and western provinces are catching up and speeding up in terms of residents’ consumption level, and the gap with the eastern provinces continues to narrow. Among the top five in the year-on-year growth rate of per capita consumption expenditure, Hubei, Heilongjiang, Guizhou and Xinjiang are all central and western provinces, among which Hubei and Heilongjiang rank in the top two with growth rates of 26.14% and 25.66% respectively.

　　Strive for "wonderful all year round"

　　In the fourth quarter, all localities have indicated that they will continue to co-ordinate the prevention and control of epidemic situation and economic and social development, and strive to achieve "wonderful all year round" economic recovery and development.

　　Hubei Province has made it clear that it will "sprint with all its strength" in the fourth quarter and strive to achieve "a beautiful start and a wonderful year". "The first quarter ‘ Open higher and walk higher ’ , the second quarter ‘ Half-way wonderful ’ , the third quarter ‘ Pressurize and stabilize, and the development resilience continues to appear, laying a good foundation for achieving the goal of economic and social development throughout the year. Ye Fusheng, chief economist of Hubei Provincial Bureau of Statistics, said.

　　Benefiting from the free trade port policy dividend, Hainan’s GDP growth rate in the first three quarters ranked second in the country. According to the local authorities, the implementation of major projects in the Free Trade Port will be accelerated in the fourth quarter, reaching a new level.

　　Beijing’s economic growth rate in the first three quarters surpassed Shanghai for the first time in recent years, ranking third in the country, with the new economy accounting for nearly 40% of Beijing’s GDP. Recently, the North Exchange was officially launched. As various policies and measures continue to be effective, Beijing said that it has the ability and conditions to complete the expected goals and tasks for the whole year.

　　Many experts also pointed out that although the high-quality economic development of various provinces in the first three quarters handed over excellent answers, on the whole, there are still differences in the level of economic development between different regions and different provinces. In the next step, we should continue to focus on promoting coordinated regional development.

　　In the first three quarters, the provinces whose GDP growth rate was higher than the national average were mostly the eastern provinces and the central provinces; On average, the growth rate of western provinces in the first three quarters was relatively low, which was not satisfactory.

　　"This is first of all due to the recurrence of epidemics in some provinces, which affects the local economic growth momentum. Secondly, the industrial structure in the western region is relatively simple and relatively dependent on investment. " Su Jian analysis. In addition, due to factors such as sporadic epidemics and extreme weather, the recovery of consumption and investment in some central and western provinces is relatively slow. "This reveals some bottlenecks in regional economic development, and some provinces rely more on the development model of undertaking industrial transfer and scale growth at home and abroad, which needs to be upgraded urgently." Su Jian said.

　　Su Jian believes that in the process of promoting regional coordinated development, we should continue to strengthen regional cooperation and form complementary advantages. At the same time, local governments should combine the industrial structure and resource endowment in the region, formulate differentiated policy programs, and adhere to local conditions, classified guidance, and targeted policies. In addition, we should give full play to the role of foreign markets, base ourselves on the highland of opening to the outside world in the pilot free trade zones around the country, and drive the development of surrounding areas.

　　"In this process, we should increase investment in infrastructure, reduce the cost of regional economic cooperation, and build a growth engine of strategic emerging industries with unique characteristics, complementary advantages and reasonable structure. We will continue to promote the coordinated development of urban agglomerations and metropolitan areas in the eastern, central and western regions, focusing on areas with economic development advantages such as central cities and urban agglomerations, forming an important power source for high-quality development and driving the overall improvement of national economic efficiency. " Su Jian said.

Six departments jointly issued a new deal-
The development prospect of cross-border e-commerce can be expected

The first China International Import Expo sent a clear signal to stimulate the import potential and accelerate the development of new formats and new models such as cross-border electronic commerce. The the State Council executive meeting held not long ago decided to continue and improve cross-border electronic commerce’s retail import policy and expand its scope of application.

The Ministry of Commerce, the Development and Reform Commission, the Ministry of Finance, the General Administration of Customs, the State Administration of Taxation and the General Administration of Market Supervision recently issued the Notice on Improving the Supervision of Retail Imports in cross-border electronic commerce (hereinafter referred to as the Notice). On December 7th, the State Council held a routine briefing on the State Council policy. Li Chenggang, Assistant Minister of Commerce, Feng Jinping, Director of the Customs Department of the Ministry of Finance, and Wang Wei, Director of the Port Supervision Department of the General Administration of Customs made authoritative interpretations on relevant policies after the transition period of cross-border e-commerce retail import.

More quality and diversified consumer demand will be met.

"This policy adjustment, for consumers, means that more quality and diversified consumer demand will be better met." In response to a reporter’s question, Li Chenggang said that this is also an inevitable requirement of China’s supply-side structural reform, and it is also a requirement to adapt to the high-quality consumption of residents in the high-quality development stage of the new era.

This regulatory policy for cross-border e-commerce retail import will be officially implemented from January 1st next year. On the basis of zero tariff within the quota for the goods in the cross-border e-commerce retail import list, the import value-added tax and consumption tax will be levied at 70% of the statutory taxable amount, and the scope of goods enjoying preferential policies will be further expanded. 63 tax items with large demand will be added, and the single transaction limit of goods enjoying preferential tax policies will be raised from the current 2,000 yuan to 5,000 yuan, and the annual transaction limit will be raised from the current 20,000 yuan per person per year to 2.5%.

China is the world’s first online retail market, with the largest number of online shopping users in the world. In recent years, the development of cross-border e-commerce retail imports has shown rapid growth. According to customs statistics, in 2017, China’s cross-border e-commerce retail imports reached 56.6 billion yuan, a year-on-year increase of 75.5%.

"Cross-border e-commerce is a new format and a new model. We generally insist on encouraging the development of this format and at the same time adhering to the principle of tolerance and prudence in its supervision." Li Chenggang pointed out that after this adjustment, on the one hand, the regulatory policy is more perfect, on the other hand, the product range is further expanded, and the application of preferential tax policies is wider.

Since May 2016, China has implemented a transitional arrangement of "temporary supervision of personal belongings" for cross-border e-commerce retail imports, which has effectively promoted the stable development of the industry, but there are also problems such as unclear rights and responsibilities of all parties and unstable policy expectations. The new deal after the transition period has removed the word "temporary", which means that this new deal will be a relatively long-term arrangement, which will promote the sustained and healthy development of cross-border e-commerce retail imports.

"Cross-border e-commerce retail imports are different from general trade, mainly to meet the quality and diversified consumption needs of domestic residents, and must be directly facing consumers and limited to personal use. Based on this premise, we clearly supervise the cross-border e-commerce retail imports according to the personal use of imported goods. This is the basis of specific regulatory requirements and the most concerned issue for industry enterprises. " Li Chenggang said.

"online celebrity" goods entered the list, and 22 new pilot cities were added.

Steam goggles, household dust meters, razor blades, sparkling wine, malt-brewed beer, binoculars, electronic game machines, ski boots, roller skates … The Ministry of Finance took the lead in adjusting and improving the list of cross-border e-commerce retail imports and tax policies, adding a total of 63 tax items, mainly involving some food, textiles and clothing, shoes and boots, jewelry, small household appliances, cultural and sports supplies, fitness equipment and other commodity categories, and some "online celebrity".

"In order to meet the needs of domestic consumption upgrading, we have adjusted the list of commodities and selected some commodities with relatively strong consumer demand in recent years." Feng Jinping told reporters, "In terms of transaction limits, the single transaction limit and the annual transaction limit will be raised this time, and the camera will be increased with the increase of residents’ income in the future."

At the same time, further increase support for cross-border e-commerce and expand the scope of policy application. On the basis of the existing 15 pilot cities, the Notice extends the scope of application of the policy to 22 newly approved cities in the cross-border e-commerce comprehensive test area, such as Beijing, to further improve the regional layout, promote the development of the industry, and better meet the consumer demand of residents.

In accordance with the principle of "responsibility", the Notice puts forward specific and clear requirements for the responsibilities of all parties-cross-border e-commerce enterprises bear the main responsibility for commodity quality and safety; Cross-border e-commerce platforms must handle industrial and commercial registration in China and fulfill the responsibility of advance payment; Domestic service providers are entrusted with the responsibility of truthfully reporting; Consumers bear the obligation to pay taxes; Government departments need to monitor the quality and safety risks of cross-border e-commerce retail imports. "Further clarifying the responsibilities of all parties involved in cross-border e-commerce retail transactions will help strengthen post-event supervision and strengthen quality risk prevention and control, which will help better safeguard the legitimate rights and interests of consumers and promote the healthier development of the industry." Li Chenggang stressed.

The future prospects of cross-border e-commerce can be expected, and effective supervision will continue to improve.

According to Wang Wei, from January to October this year, the total retail import and export volume through the customs cross-border electronic commerce platform reached 111.04 billion yuan, an increase of 86%. Among them, imports were 67.18 billion yuan, a year-on-year increase of 53.7%; Exports reached 43.86 billion yuan, up by 173.9%.

"In recent years, China’s total import and export trade has been around 4 trillion US dollars. As a new format, cross-border e-commerce accounts for a relatively small proportion in the total foreign trade plate, but it has grown rapidly. From an international perspective, the future prospects of cross-border e-commerce can be expected." Li Chenggang said.

Cross-border e-commerce retail import is not only a new format and a new topic for China, but also for the whole world. Effectively supervising this new format and new model is actually a process of crossing the river by feeling the stones.

"According to the characteristics of electronic, recordable and traceable cross-border e-commerce retail import transaction information, the Notice clearly requires enterprises to establish and improve quality and safety risk prevention and control mechanisms and commodity quality traceability systems, and truthfully transmit electronic information to the regulatory authorities, and cooperate with the regulatory authorities to carry out quality risk monitoring to prevent and control quality and safety risks." Li Chenggang pointed out that for commodities and related enterprises with quality and safety risk accidents, government departments will also publicize information according to regulations to better ensure consumer safety.

Wang Wei told reporters that in 2016, the General Administration of Customs researched and formulated and released the "Announcement No.26", which clarified the customs supervision measures for cross-border e-commerce. This time, in line with the introduction of the New Deal, the Customs revised and improved the "Announcement No.26", which will be released and implemented in the near future. On the other hand, the national customs has upgraded and improved the e-commerce system according to needs to ensure the healthy and sustainable development of cross-border e-commerce.

"Cross-border e-commerce has the characteristics of rapid development, diversified commodities and rapid renewal. The Ministry of Finance will work with relevant departments to adjust the list of imported goods of cross-border e-commerce in a timely manner according to these characteristics and taking into account the development of cross-border e-commerce, consumer demand and regulatory conditions. " Feng Jinping said.(Reporter zhang yi)

First, the third generation synchrotron radiation light source with the highest energy in the world

SPring-8, a large-scale synchrotron radiation facility in Japan, is located in Harima Science Garden City, Hyogo) in Hyogo Prefecture, the center of the Japanese archipelago. It is the third generation synchrotron radiation source with the highest energy in the world. Its English name is Spring-8, which means "8GeV Super Photon Ring", that is, the output power is 8 GeV.

In 1991, under the leadership of MEXT (Ministry of Education, Culture, Sports, Science and Technology), Jaeri (Japan Atomic Energy Research Institute) and Riken (the Institute of Physical and Chemical Research) of Japan began to jointly build SPring-8. The construction cost of the first phase is about 110 billion yen, and the land is donated by Hyogo Prefecture for free. With the joint support of the county government, the county university, various research institutes and commercial enterprises, the project was completed in 1997, and the facilities were opened, which were managed by JASRI (Japan Synchrotron Radiation Research Institute), including the operation, maintenance, transformation, user service and scientific research and development of light sources. JASRI is the only statutory management organization of SPring-8, which is private and non-profit, and employs more than 1,000 employees, 80% of whom are researchers and technicians. From October 1997 to 2010, SPring-8 has built 55 beam line stations.It has served more than 100,000 people in science, industry and business circles in Japan and the world.

Spring-8 in Japan, advanced photon source APS (Argone) in Argonne National Laboratory of the United States and European synchrotron radiation facility ESRF (Grenoble) in Grenoble, France are the three largest high-energy synchrotron radiation facilities in the world.

Third, structural exploration

The accelerator of SPring-8 mainly consists of four parts:　

* injector, Linac, 1GeV；;　

* Booster, 8 GeV;

* large Storage Ring, storage ring, 8GeV, used for high brightness X-ray;　

* Small storage ring, NewSUBARU, 1.5GeV, used for medium short pulse soft X-ray.

　　1. Injector (Linac)　

The linear accelerator section is equipped with 26 3-meter-long accelerating units to accelerate the electron beam energy to 1GeV. The red part in the picture below is a quadrupole magnet used to focus the electron beam.　　

Linear accelerator unit 1　

The electron beam is generated by a thermionic gun impregnated with barium and tungsten. The ion gun is located on the high-voltage board with a voltage of about 180KV. The pulse duration is 1ns or 40ns. The selected beam is focused on a buncher and accelerated to 1GeV energy with 25 accelerating cavities. Electron beam energy dispersion is reduced by energy compressor system (ECS). Then, the linear accelerator as the injector transports the electron beam to the intensifier or the NewSUBARU small storage ring.　

Some parameters of linear accelerator:

2. Booster Synchrotron

Annular, with a circumference of 396 meters. The 1GeV electron beam output from the linear accelerator will be accelerated to 8GeV in the intensifier. The blue image below shows the deflection magnet, which is used to generate synchronous radiation light; The yellow part is a six-stage magnet for stabilizing the electron beam.

Intensifier tunnel intensifier branch point (left) electron beam transport line SSBT (right)　

In FODO, the magnetic focusing structure of the intensifier, bending magnets and quadrupole magnets are alternately arranged, and the repetition frequency of injection, acceleration and output is set to 1Hz, and the harmonic number is 672. If a single beam is injected into the storage ring, an RF elimination system is installed to eliminate other electron beams adjacent to the main beam. The special timing system injects different beams according to the types of light required by each outlet station of the storage ring.　

Some parameters of the enhancer:

3. The large Storage Ring (storage ring)

The electron beam is injected into the storage ring from the transport line SSBT (left).

Huge ring with a circumference of 1436 meters. Its conventional unit consists of 2 deflection magnets, 10 four-stage magnets and 7 six-stage magnets, and its length is about 30 meters. The linear joints are located between conventional units, and are used to install plug-ins, RF accelerating cavities, beam injection systems, beam diagnosis systems, etc., with a total of 44 linear joints.　

Some parameters of large storage ring:

The large storage ring can store 8GeV electron beams for a long time, more than 100 hours. The energy consumed by synchrotron radiation is replenished by accelerating equipment installed in four radio stations around the storage ring. The constant current (top-up) injection mode effectively ensures the constant beam current intensity in the storage ring.　

Link: The 86th academic seminar of the Oriental Science and Technology Forum was held on December 7-8, 2006, with the topic of "beam orbit stability of the third generation synchrotron radiation light source".　

Dr Kouichi Soutome from Japan synchrotron radiation research institute (JASRI) gave a special report on "constant current injection and beam orbit stability of SPring-8". He first emphasized the necessity of providing users with a stable X-ray beam for precision experiments. In order to stabilize the beam position, it is necessary to restrain the beam trajectory change. He pointed out that the top-up injection mode with constant beam intensity in the storage ring can effectively ensure the stability of the synchrotron radiation light intensity. For this reason, SPring-8 has made great efforts to study the sources of various factors that cause orbit change, such as the change of magnet power supply and the vibration of vacuum chamber caused by cooling water.

SPring-8 also improves the beam trajectory correction system and the corresponding measurement system. For top-up implantation, SPing-8 adopts many measures, such as reducing the vibration of stored electron beam caused by implantation, reducing the loss of implanted electron beam, and maintaining long-term high-purity single beam implantation. Finally, he reported the stability of SPring-8 in beam orbit and the performance of top-up injection operation mode. The total current stability in SPring-8 storage ring is controlled within 0.1%, and the current intensity inconsistency of each beam is also controlled within 10%.　

4. NewSUBARU

　　NewSUBARU storage ring　

NewSUBARU, a small storage ring with 1.5GeV, is mainly used to study the application of soft X-ray in industrial field. Built in 1998, Lasti (Laboratory of Advanced Science and Technology for Industry) of Hyogo University is responsible for its operation.　

The circumference of the small storage ring is about 119 meters, and it consists of two 14-meter and four 2.6-meter straight-line sections. In the long straight section, an 11-meter-long undulator and an optical klystron free electron laser device are installed. The electron beam of 1GeV in the linear accelerator can be directly injected into the storage ring.

　　11-meter-long undulator

Some parameters of small storage ring:

Four, beam line and experimental station

SPring-8 has 22 beam lines led by deflection magnets, and up to 24 can be built. There are 26 beam lines led out by the insert, up to 34 can be built, and the length of the straight line section is 4.5 meters; There is one beam line led by the long insert, and at most four beams can be built, and the length of the long straight line section is 25m. These beam lines are generally designed within 80 meters, but 9 can extend to 300 meters and 3 can extend to 1 kilometer.　

1. Layout and classification　

The front-end assembly of the beam line is designed to withstand radiation power, reduce the thermal load of the first optical element in contact, and protect the vacuum of the storage ring in case of beam line failure.

V. Major scientific research achievements

1. Uncover the secret of the mysterious structure and movement mode of water molecules.

Water is a familiar substance, and the structure of water molecule H2O is well known. But perhaps people haven’t thought deeply: where does ice store huge cooling energy? Why is the density of water the highest at 4oC? But above or below 4oC, the water density decreases? Why is the density of solid ice less than liquid water?

Japanese scientists analyzed the structure of water and ice in SPring-8, and some new discoveries solved the long-debated problem about the nature of water. They successfully conducted Compton scattering experiment by using high-energy inelastic scattering beam line BL08W, directly observed the structure and function of ice at high resolution, and verified the accuracy of molecular dynamics simulation. This basic research result can help to develop thermal storage materials and analyze the thermal storage of new materials in the future. The paper was published in the top American science journals.

In fact, as early as 2008, scientists from RIKEN Institute of Physics and Chemistry in Japan proposed two water states with different hydrogen bonding modes by using BL17SU beam line and soft X-ray spectrum of SPring-8, as well as small angle scattering and Raman scattering.

2. Develop general-purpose plastic materials as strong as iron.

Plastic products such as plastic bags and plastic buckets have become widely used and indispensable items in our daily life because they are light, waterproof and cheap. But at the same time, it also has some disadvantages: low tensile strength, easy deformation and not high temperature resistance. They are synthesized from polymers such as polyethylene and polypropylene, and their structures at the molecular level are composed of long chains of carbon atoms. This "string" structure of polymer makes plastic products as soft as biomaterials. However, scientists have found that the tensile strength of materials will increase with the increase of polymer chain length; When carbon chains have tensile strength similar to covalent bonds of carbon atoms in diamonds, general plastics will harden, but they will not have diamond-like strength.

Distinguished professor Hikosaka of The Graduate School of Integrated Arts and Sciences (Hiroshima University) focuses on the study of polymer long chains and their structural and characteristic changes. He examined the blending phase structure of polyethylene long chain and its influence on properties by X-ray diffraction and other methods. The growth mechanism, sliding and diffusion effect mechanism of ideal polymer crystals are formulated. In 1987, the "sliding diffusion theory of polymer crystallization" was put forward.

The research team led by Professor Iwasaka and his doctoral student Kiyoka Okada, who used BL40B2 beam line in 2003-2007, observed the process of nuclear nucleation. ) From 2007 to 2010, using the X-ray scattering device of SPring-8, a new polypropylene-based plastic with strong tensile force and super heat resistance was successfully developed for the first time: NOCs(nano-oriented crystals).

The reason why ordinary plastics have poor tensile strength is because of low crystallinity. High-quality plastics are those with crystallinity of about 50%. In other words, the higher the crystallinity, the stronger the intermolecular interaction, and the stronger the tensile strength and heat resistance. When polymer molecules are regularly arranged, crystals form. Therefore, in order to improve the crystallinity, it is necessary to arrange the polymer molecules regularly as much as possible.

Professor Masamichi Hikosaka, Dr. Kiyoka Okada, holds a new type of polypropylene.

The research team led by Professor Iwasaka found a method to make polymers regularly arranged when plastics are in molten state, and proved that the crystallinity of the method is 92%. Because the structure of NOCsS looks like a real armor, it is composed of small pieces of iron plates, so the model is called "real armor" model. The tensile strength of the new polypropylene is about seven times higher than that of the ordinary plastic material, the heat-resistant temperature reaches 170°C or higher than 176°C, the light transmittance is 99%, and it is recyclable and cheap, because only one process is needed in the traditional polypropylene production process.

This wonderful new plastic material is most likely to be used in the transformation of steel body in traditional automobile industry. Although the thickness of the body will be doubled, its weight is only a quarter of that of steel.

3. Analyze the change of dynamic structure of calcium pump.

A variety of ions participate in the biological activity of organisms. Calcium 2+ ion promotes muscle movement and is one of the most important ions in organisms. It is stored in the endoplasmic reticulum of myofibrils. When calcium ions are released into muscle cells, muscles contract. At the same time, calcium ions need to return to the endoplasmic reticulum to relax the muscles. A membrane protein called calcium pump is responsible for pumping back calcium 2+ ions.

Pumping back calcium ions involves two processes: obtaining and releasing, and the structure of calcium pump changes accordingly. Chikashi Toyoshima (Institute of Molecular and Cellular Biosciences of the University of Tokyo) first discovered this structural change and analyzed the calcium pump structure in nine states.

His research results were published in the British journal Nature in 2000, 2002 and 2004. In view of this series of outstanding achievements, Professor Toyoda was awarded the Asahi Prize in 2009.

4. Discovery of new magnetic materials on meteorites

Every year, thousands of tons of meteorites fall to the earth. Although their surfaces are burnt black, their internal metal and mineral components remain unchanged, so they are called "fossils" in space. It provides powerful evidence for human beings to understand the mysteries of the solar system.

Masato Kotsugi, JASRI) of Japan Synchrotron Radiation Research Institute used the Photoelectron Emission Microscope (PEEM) on BL25SU beam line of SPring-8 to analyze the structure of iron meteorites. Iron meteorite is composed of α phase rich in iron and γ phase rich in nickel. Dr. Xiao Shan confirmed that there is a nano-scale mineral layer at the interface between iron and nickel, which is called Tetrataenite. However, it does not exist on the earth and will become an excellent new magnetic material. Dr. Xiao Shan further analyzed the characteristics of Tetrataenite, which is composed of 50% iron and 50% nickel, and the iron and nickel atoms are alternately arranged, which is a regular periodic crystal structure. It produces a kind of hard magnetism, that is, the magnetization direction will not change easily. Famous hard magnetic materials include permanent magnets and materials used in engines of hybrid vehicles.

Another important discovery of Dr. Xiao Shan: Tetrataenite will be a potential substitute in hard disk manufacturing. Platinum is an indispensable material for the next generation hard disk, but it is a rare metal, and its price is rising. At present, the demand for platinum has exceeded its production capacity. About 2 tons of platinum is used in global hard disk production every year. If Tetrataenite synthesized by iron and nickel can be used as hard disk material, the consumption of platinum will be greatly reduced, thus promoting resource conservation and low-cost production of hard disks.

Chiharu Mitsumata (Toho Kyu University) of Tohoku University in Japan is carrying out basic research on the synthesis of Tetrataenite.

As a result, Dr. Koyama and Professor Sanyan won the second place in Dubose-Crouse Award (international metallic graphic contest) in 2010.

　5. Successfully developed all-solid-state safety battery by nanotechnology.

Professor Hiroshi Kitagawa (Kyoto University) of Kyoto University and Dr Rie Makiura (Kyushu University) of Kyushu University have studied nano-scale silver iodide (AgI) particles. They proved for the first time in the world that it is possible to realize stable solid electrolyte at room temperature. This research achievement is highly valued because of its great development potential. The paper was published in the British scientific journal Nature Materials in May 2009.

6. the three-dimensional structures of Rab27B and Slac2-a are analyzed.

In 2004, Dr. Mitsunori Fukuda (Tohoku University) of the Graduate School of Life Sciences of Northeastern University clarified the transmission mechanism of melanin in melanocytes at the molecular level. In 2008, in cooperation with Shigeyuki Yokoyama of RIKEN Institute of Physical Chemistry, he successfully analyzed the three-dimensional structures of Rab27B and Slac2-a in BL41XU Experimental Station of Structural Biology on SPring-8. Their structural data will greatly promote the research and development of new skin whitening products and drugs to prevent white hair.

7. The new chewing gum Pos-Ca can effectively prevent tooth decay.

Dr. Tomoko Tanaka (the Health Science Laboratory of Ezaki Glico Co., Ltd.) found that calcium phosphate oligosaccharide supported the remineralization of teeth, which promoted the appearance of new chewing gum with calcium phosphate oligosaccharide (Pos-Ca).

8. Research and development of new drugs against influenza virus

Influenza virus consists of eight RNA genes, and there are two types of spike proteins on the surface of virus particles: hemagglutinin (HA) and neuraminidase (NA). Because of its simple structure, the virus cannot replicate itself. However, they can be skillfully replicated by using the replication system of human cells after invading human host cells.

HA, like a key, can invade the human body after combining with glycoprotein on the cell surface. NA plays an important role in the separation and release of progeny virus from cells, and is an enzyme that helps the virus infect other bacteria. The amino acids that make up the above two proteins are prone to mutation. So far, scientists have discovered 16 kinds of HA and 9 kinds of NA proteins. These protein are arbitrarily combined into various types of influenza viruses (H1N1–H16N9). For example, influenza A H1N1, which was prevalent in 2009, and H5N1 virus, avian influenza, which became prevalent in 1997.

Influenza virus encodes 10 kinds of proteins, among which RNA polymerase is very important in virus gene replication. It includes three subunits: PA, PB1 and PB2. When one of them is lacking, RNA polymerase loses its enzyme function and the virus cannot replicate. Therefore, if we can determine the three-dimensional structure of these three subunits, we can block the function of RNA polymerase.

In July 2008, Dr. Sam-Sam (Graduate School of Nanobioscience, yokohama city university) successfully analyzed the combined structure of PA and PB1, and analyzed the enzyme structure related to virus replication, which will accelerate the research and development of new antiviral drugs. It is not far away to realize the wish that people don’t have to worry about the flu in winter.

9. Reveal the secret of solar system formation by analyzing comet dust.

The American Stardust Project, 1999-2007) collected scattered dust samples of comet Wilder II (81P/Wild) and brought them back to Earth. It is expected that by analyzing these samples, information about the origin of comets and the entire solar system 4.6 billion years ago can be obtained.

Dr. Tomoki Nakamura (Kyushu University) of Kyushu University has conducted in-depth research on comet dust. He used the X-ray diffraction experimental device of BL37XU on SPring-8 and the synchrotron radiation facility of KEK to analyze and determine the crystal types and abundance ratio of dust. After that, Professor Akira Tsuchiyama (Osaka University) used the CT scan of BL47XU to visualize the internal structure of comet dust.

Dr. Nakamura found that "meteorite chondrules" originated from comet dust outside the solar system, so they can no longer be explained by the traditional model of solar system formation. "Meteorite chondrules" are the main components of ancient meteorites, rich in magnesium, silicon and a small amount of iron. The doctor believes that the migration of "globules" occurred in the primitive solar system composed of dust disks; However, he said that the analysis accuracy of at least 20 samples will be improved to obtain statistically significant conclusions. He will also continue to carry out comet meteorite dating and determine the migration time. It is expected that a new solar system formation model will be established soon.

10. Nanotechnology promotes the innovation of "new materials"

The shape characteristics of fullerenes discovered in 1985-containing 60 carbon atoms, like a football-have aroused widespread concern in the scientific community. In 1991, columnar carbon nanotubes were discovered. In January, 2008, Associate Professor Kitura & Hisa Nori Shinohara (Nagoya University) of Nagoya University successfully synthesized a nano-scale metal wire.

Carbon allotropes: diamonds and graphite, fullerenes and carbon nanotubes.

Pure gold is prone to oxidation reaction, but a very thin nanowire can exist stably in the air because nano-scale materials have a unique stable structure. In order to observe the internal structure of nanotubes, Associate Professor Bei Puliang conducted solid soft X-ray spectroscopy experiments at BL25SU experimental station in Spring–8. He observed that the absorption of Er by X-rays was unique, thus confirming that ErCl3 line was formed in carbon nanotubes.

Carbon nanotubes in fullerenes look like pods.

ErCL3 structural model (Er atoms in red and CL atoms in green)

Professor Tian Zhuo (University of Tokyo/RIKEN) of Tokyo University and Institute of Physical Chemistry is regarded as the most imaginative and productive polymer chemist in the world. In recent years, he took SPring-8 as an important research tool, and first successfully determined the structure of a new type of conductive graphite nanotubes. Then, he showed with solid evidence that the hydrophilicity and hydrophobicity of graphite molecules were closely connected in hydrophobic groups, forming tubular spiral molecular pairs. In addition, he also successfully designed a liquid crystal phase with short intermolecular programs. Both research results were published in the Journal American Chemical Society in 2008. In 2009, the design of "bicontinuous cubic liquid crystal materials in discoid molecules" was published on the cover of the magazine of American Chemical Society, and he also won the Polymer Chemistry Award of American Chemical Society.

11. Develop earthquake observation technology.

With the joint efforts of Tokyo Institute of Technology, Japan Agency of Marine-Earth Science and Technology and Japan Synchrotron Radiation Research Center (JASRI), it is found that the deepest part of the earth’s core is made of iron with hexagonal close-packed structure. The state of metallic iron under ultra-high pressure and ultra-high temperature conditions is similar to the state of the earth’s core simulated by ultra-high pressure and ultra-high temperature. Scientists used SPring-8 high-brightness X-ray to observe the changes of single crystal structure of metallic iron, and found for the first time that the hexagonal close-packed structure was stable under extreme conditions of high temperature and high pressure. The analysis of the crystal structure is helpful to the analysis of earthquake observation and greatly strengthens people’s understanding of the formation and development of the core. This achievement was published in the American journal Science on October 15th, 2010.

12. Analyze the gel mechanism of self-assembly from the molecular level.

Recently, a joint research group of The University of Kitakyushu and JARSI announced that the molecular structure of the solvent in the gel state was analyzed on the BL03XU Advanced Soft Materials and BL40B2 Structural Biology II Experimental Station by using SPring-8 high-brightness synchrotron radiation. The research results benefit from organogelator (low molecular weight compound). As long as 1% solvent is added to it, the whole solvent will gel, which will greatly help to prevent environmental pollution caused by offshore oil spill. The paper was published online in the October 2010 issue of Polymer Journal.

Sixth, look forward to the future

The resolution of traditional optical microscope is limited by the wavelength of light, while the wavelength of X-ray is 10,000 times shorter than that of visible light, and the resolution reaches the atomic level, which means that the three-dimensional structure of a single atom in matter can be observed. X-ray is widely used in medical treatment, life science and material science. However, the light generated by X-ray light sources (including synchrotron radiation) is not uniform and the wave fields are inconsistent. Laser can produce uniform light by using a pair of mirrors. This urges scientists to make every effort to explore a new technology to realize a mirrorless laser, that is, XFEL: X-ray Free Electron Laser (XFEL). XFEL is an X-ray that combines the characteristics of free-electron laser. It is called the most promising new light source in the future with the most scientific exploration and discovery value. It is also called "dream light source" and "new dawn of the scientific era". It has the dual characteristics of laser and radiation light, and can work in the whole X-ray band. It is much better than the third generation synchrotron radiation light source in brightness, coherence and time structure, and is internationally recognized as one of the feasible technical routes of the "fourth generation light source".

The United States, Europe and Japan have successively developed XFEL, and raised it to the height of national strategy to deploy and implement it. LCLS(Linac Coherent Light Source, Stanford Linear Accelerator Center, USA), the first X-ray free electron laser device in the world, came out in 2009. The European Free Electron Laser Facility (European XFEL) is jointly participated by DESY of Germany and 11 other European countries. The core project is a 3.4-kilometer underground tunnel, which was officially started on July 1, 2010. It is expected to be completed in 2014 and the first scientific experiment will be conducted in 2015.

SPring-8 has already started the prefabrication and research of XFEL, and the accelerator prototype has successfully produced the first laser beam. In 2006, the XFEL project started. At present, the 700-meter-long 8GeV X-ray free electron laser device is under final construction and is expected to be put into operation in fiscal year 2011. exist

2.XFEL facilities

SPring-8′ s X-rays can produce light 10 billion times brighter than the sun, while XFEL produces light 1 billion times brighter than SPring-8, and the pulse is 1000 times shorter than the existing X-ray source. The higher brightness light source enables scientists to observe the three-dimensional structure of atoms and their ultra-fast motion more realistically.

Design parameters:

Electron beam energy: 8 GeV

Electron beam diameter: 40 um

X-ray wavelength: > 0.06 nm

X-ray peak power: 5 GW

X-ray pulse length: < 100fsec

X-ray peak brightness: 1033 photons/s/mm2/mrad2/0.1% b.w. 。

The original quality of electron beam determines the quality of free electron laser. Scientists have specially designed an ultra-high voltage thermal electron gun, which uses a single-crystal cerium-hexabromoboride cathode (CEB 6) to emit a fine, highly collimated and stable electron beam. Then, it is transported into the electron beam compression system, and the peak current will be strengthened to several thousand amperes.

The electron beam energy is rapidly increased to 8GeV by a C-band linear accelerator, and then transported into a vacuum undulator to generate intense XFEL radiation.

3. Create new technologies

Coherent X-ray imaging technology: Microscopic images of various materials at atomic level can be obtained.

Imaging process: X-ray laser → sample → coherent scattering mode → phase recovery → clear structure image.

XFEL’s ultrashort pulse can detect the ultrafast motion of matter in femtosecond.

Protein Structure Analysis: The analysis of new materials will surely lead to the birth of new functional products in biology and medicine.

Living cell biology: Real-time data acquisition will open a new way for the study of living cells.

Nanotechnology: Ultra-short wave XFEL will help to create new functional materials.

With XFEL, scientists can observe extreme phenomena in astronomy, plasma science and basic physics.

The Institute for Molecular Science, Niigata University, Nagoya University and JASRI/RIKEN of the National Research Institute of Japan jointly studied the intense ultraviolet free electron laser irradiated to argon atoms, and successfully analyzed the specific process of multi-electron emission.

In order to accurately measure the fluctuation in free electron laser, scientists analyzed all the electronic energy of argon atom irradiated by laser pulse at the speed of 20 pulses per second. They found that the absorption of electrons and multiphotons only occurs when the light intensity is very high, and clarified the importance of resonance state in multiphoton absorption. The research results show that the research of nano-science, nano-technology and material preparation can be promoted by using X-free electron laser on the basis of selecting appropriate laser wavelength and corresponding resonance conditions. The paper was published in american physical society’s scientific journal Physical Review Express on September 24th, 2010.

　　Beijing Youth Weekly reported on May 7. Becoming famous because of "Tang Priest", being controversial because of marriage, and being calm because of Buddhism-

　　Born into a family of Peking Opera, he was deeply influenced by art since childhood and naturally embarked on the road of performing arts.

　　Passing Yang Jie, the director of The Journey to the West, made him become attached to Tang Priest, and successfully shaped the role of Tang Priest in The Journey to the West, becoming the last Tang Priest to "get the true scriptures";

　　His marriage with Ms. Chen Lihua, who is ten years older than him, has caused a lot of controversy, and he laughed it off.

　　After the marriage, he quietly walked off the stage, quit the screen, and then walked out of the public eye.

　　● Yesterday reappeared.

　　On December 23rd, 1952, Zhongrui Chi was born into a family of five generations of Peking Opera in Beijing. He was deeply influenced by the art of Peking Opera since childhood. However, Zhongrui Chi failed to take the road of Peking Opera in the end, for one thing, he was 1.80 meters tall, and for another, he caught up with the Cultural Revolution in China.

　　Although he didn’t enter Beijing Opera, the artistic edification he received since he was a child can’t be lost. Zhongrui Chi took a tortuous artistic path: first he worked as a farmer in Heilongjiang Construction Corps, and then he worked as a literary and art soldier in Yunnan. After he retired, he was admitted to China Broadcasting Art Troupe. Two years later, he was sent to Shanghai Theatre Academy to go to college and became the first batch of college students after the Cultural Revolution.

　　After graduation, Zhongrui Chi came to China TV production center and became a professional actor. He has shot a large number of film and television works, playing Du Mingguang in Golden Late Autumn. The second son Huan in "Love in the Pen"; Sun Shuikang, the leader of aquatic products in This is not a misunderstanding; Characters such as Sai Shang Xiao in Harbin at Night.

　　One day in 1984, Zhongrui Chi finished filming Harbin at Night and went back to the troupe to get his salary. In the dark corridor, he almost ran into an oncoming stranger, Yang Jie, the director of The Journey to the West.

　　At that time, The Journey to the West had just filmed half of it. Xu Shaohua, the actor of Tang Priest, had to leave the crew for some reason. Without the "master", the whole crew was in a state of downtime, and director Yang Jiezheng was so anxious about it that she met Zhongrui Chi.

　　"I have to say that this is the Buddha’s edge. When I passed by in the corridor, Yang Jie decided that I was the best candidate for Tang Priest. A week after we met, I put on my cassock and rode on Bai Longma. "

　　In 1988, The Journey to the West premiered in China, and the Tang Priest played by Zhongrui Chi was unanimously recognized by the audience. The four men became the most popular stars for a time, and attracted much attention wherever they went. However, at this moment, Zhongrui Chi chose to leave. He married Ms. Chen Lihua, the richest man in China, who was ten years older than him, and retired from the entertainment industry and started a new life.

　　Our reporter takes you to visit the new life in Zhongrui Chi.

　　They had a glorious history; They may have spent your youth with you; They used to be idols of a generation … Time flies and times have changed. Now they have bid farewell to their glory and started a new life. Show you their second life by comparing them. In this issue, the character-Zhongrui Chi is recorded.

　　"Late Chief" in Luxury Palace [nowadays]

　　At 9: 00 a.m. in a spring March, we arrived at the gate of China Red Sandalwood Museum on the northwest side of Gaobeidian Bridge in Beijing’s East Fourth Ring Road. Compared with the busy and congested streets in the morning rush hour, it was particularly spacious and deserted.

　　At the gate, a big boy wearing a security uniform just pushed out the wooden box for collecting tickets. Under his guidance, we bypassed the museum in front and came to the back. We walked past a stone bridge, and there was a building with more than ten floors. The exquisite decoration of the building made people think of the word "magnificent". Upstairs, in the middle of the building, the three golden characters "Lihua Pavilion" shine in the sun.

　　Walking into the interior of Lihua Pavilion, you will immediately feel the solemnity and luxury inside, just like walking into an ancient palace: there is a wide rosewood screen facing you, a huge and beautiful crystal chandelier overhead, all doors, windows and partitions are made of wood, with couplets and carved beams and painted buildings, and two elevators are hidden behind the antique wooden door frame, which makes people have to sigh the perfect combination of classical and modern.

　　This is a modern comprehensive building with a classical appearance, with office area, hotel, gym, swimming pool, KTV and so on.

　　We were taken into a reception room on the second floor. There are three floors in the room, which are still wooden doors, wooden windows and wooden floors. The outermost room is a rosewood screen, a plush chair and a mahogany long table, the second room is a circle of sofas and coffee tables, and the innermost room is a rosewood collapse. No sooner had we settled down in the plush chair than someone came in and poured tea.

　　After sitting for a moment, with the sound of footsteps coming from the corridor and the greeting of the staff, Zhongrui Chi came in. He was in a good mental state, flushed and with a gentle smile on his face. It is still the appearance of the Tang Priest in The Journey to the West in the past, and it is still a loud and magnetic voice. The opening remarks are: "As soon as you see this rosewood museum, you will understand what I have done since I left the audience for more than ten years, at a glance."

　　Why did Zhongrui Chi, who successfully shaped the role of Tang Priest in The Journey to the West, put aside his good performing career and open the rosewood museum instead? This has to start with his marriage.

　　In a resort hotel in Suzhou, Ms. Zhang and her family booked a 2-night stay, as well as a 2-day vegetarian meal and Chinese massage. "Our family has &lsquo; Yangkang &rsquo; After a while, the relevant policies have been relaxed, and our family has not traveled for a long time, so we hope to go out for fun, but unlike before, &lsquo; Yangkang &rsquo; After that, we paid more attention to healing tourism, instead of arranging too full a trip, mainly to relax ourselves and even add some rehabilitation projects. " Ms. Zhang said.

　　Ms. Zhang’s travel choices and ideas are typical representatives of many tourists this year. CBN recently publicly conducted a questionnaire survey on "Consumer Recovery, Will You Buy in buy buy?" After collecting more than 1,200 valid questionnaires, it was found that it was asked "Which fields of goods or services would you consume?" At that time, tourism ranked first, reaching 91.24%. In other words, tourism that can satisfy people’s spiritual pleasure consumption is what most people will choose in the consumer market this year, and many tourists’ willingness to travel this year is obviously strengthened compared with previous years.

　　After recent interviews and investigations, the First Financial Reporter learned that this year, with the recovery of outbound travel and the warming of inter-provincial travel, tourism will inevitably usher in recovery and business opportunities. After experiencing the epidemic, more tourists began to favor healing tours and some extended cultural tours with experience. Of course, how to restart the outbound travel business, do a good job in the derivative projects of Dawen Travel and attract tourism professionals are also challenges that the industry needs to face.

　　90% of the respondents want to travel, and nearly 60% of the tourists have a single budget of more than 10,000 yuan.

　　In the three years since the epidemic, outbound travel has been suspended, domestic travel has been repeatedly blown, and repeated epidemics in various places have also made scenic spots open and closed. Local consumption has become the main mode of tourism in the past three years, which has given birth to some in-depth local tourism products.

　　This year, with the relaxation of relevant policies, people’s willingness to travel, which has been suppressed for many years, seems to have a "small blowout". According to the questionnaire survey of CBN’s Consumer Recovery, Will You Buy in buy buy, 91.24% of the respondents chose to have a travel plan this year. When asked whether this year’s willingness to travel has increased compared with previous years, 85.85% of the respondents said that this year’s willingness to travel has increased or at least remained the same.

　　The above questionnaire survey also shows that 60.2% of the respondents have plans for domestic travel this year, and 32.37% of the respondents plan to go both for domestic travel and outbound travel this year.

　　In terms of tourism consumption expenditure, 57.39% of the respondents have a budget of 10,000 ~ 20,000 yuan per capita for single tourism consumption this year, and 32.6% of the respondents have a budget of 5,000 ~ 10,000 yuan for single tourism consumption, accounting for 5.63% of the respondents with 1000 yuan ~ 5,000 yuan.

　　"In 2019, the tourism industry reached a relative peak. The tourism market in the past few years should have been very vigorous. However, when it encountered an epidemic, both domestic and outbound travel were hit. However, after the epidemic, people have strengthened their willingness to travel, and some spiritual pleasures have been favored by people. You see, in the consumption of Women’s Day just past, &lsquo; Yueji &rsquo; It’s a key word. Women are very particular about their inner experience when they travel. Therefore, we will see that in the process of consumption recovery this year, more subdivided products with spiritual pleasure will be released, and more themed tourist routes and accommodation products will be developed. " Cheng Chaogong, chief researcher of Tongcheng Research Institute, told the First Financial Reporter.

　　Inter-provincial tourism is heating up, and the healing market has great potential.

　　According to the tourism market data of Spring Festival, Women’s Day and other nodes this year, domestic tourism is the first to recover, and the results of the questionnaire survey of "Consumption Recovery, Will You Buy in buy buy" of CBN also show that 60.2% of the respondents have plans for domestic tourism this year.

　　"Last year’s camping was in the market &lsquo; Kill &rsquo; Out of a horse &lsquo; Dark horse &rsquo; In fact, it is also a market cultivated because everyone can only focus on local consumption. Among them, the consumption of camping, RV and related supplies increased significantly in 2022. " Yang Songbai, general manager of RV Life Home, told the First Financial Reporter.

　　According to the data of companies such as Ctrip, Tongcheng, Mama Donkey, Flying Pig, Qunar, Tuniu, Mahoneycomb and Spring and Autumn Tourism, last year, in low-risk areas, the "two-hour holiday circle" became the mainstream. Last year, the local tour orders during holidays such as "May Day" accounted for more than 80%, and most of them were non-group tourists, while camping became a "dark horse". The surrounding camping market continued to heat up during the "May Day" last year, and the popularity of "camping" related travel search increased by 117% from the previous month. At that time, the number of camping orders for flying pigs increased by over 350% month-on-month, and Hangzhou, Chengdu, Guangzhou, Shenzhen, Wuhan, Beijing, Zhuhai, Changzhou, Foshan and Chongqing ranked among the top ten cities in China as popular camping tourist sources.

　　In Yang Songbai’s view, after the rapid recovery of cross-provincial tourism this year, camping and other popular tourism projects last year can still be continued, but we must make sub-products that meet the needs of consumers. "For example, some high-quality local tourism projects can be retained, but they can be combined with inter-provincial RV camping, travel agency channel marketing and local homestays to make domestic tourism products. Nowadays, there are many young guests who like to drive by car, experience special homestays and travel freely. We must understand their needs. " Yang Songbai told the First Financial Reporter.

　　In addition to camping and RV tours, three years after the outbreak, a large number of consumers are paying more and more attention to health-related consumption, and healing tourism is one of them.

　　According to the survey results of CBN’s "Consumer Recovery, Will You Buy in buy buy?", more consumers have increased their spending in the health field this year, among which 87.18% of the respondents have a willingness to consume healthy food. It is worth noting that as many as 55.24% of the respondents are willing to participate in healing tourism this year, and 30.15% of the respondents have plans to participate in rehabilitation activities this year. It can be seen that healing tourism is a bright direction in the recovery of tourism consumption this year.

　　"The epidemic once pressed the pause button for our industry, but this year is definitely a business opportunity for recovery. There are two sides to everything. Although the epidemic situation has a great impact on the cultural tourism industry, it has also made more consumers pay attention to health care, and healing tourism has become a trend. The core products of the project "Yin Yu Shui Zhong Tian" invested and developed by us include the journey of mindfulness life, the series of trips of body and mind co-cultivation, etc. to help guests understand their physical and mental health, and also include service teams such as Chinese medicine practitioners, rehabilitation experts, health coaches and nutritionists. These holiday tourism projects combined with healing courses are very in line with people’s demand for recreational travel this year. This year, our key planning project is the Unity International Cultural Festival, to discuss with the industry how to cope with the challenges brought by the development of the times. This year, we will continue to deepen the health industry and continue to help promote the development of the big health industry. " Cao Weide, chairman of Wanbang Pan Asia Group and founder of Yinyu, said in an interview with China Business News.

　　It is precisely because of the warming of healing tourism that according to the data of Ctrip, Tongcheng, Mama Donkey, Flying Pig, Qunar, Tuniu, Mawei and Spring and Autumn Tourism, the heat of cities near and south of the Tropic of Cancer such as Sanya, Zhuhai, Xishuangbanna, Dali, Xiamen, Haikou, Tengchong and Beihai soared. Among them, the healing holiday tour in Sanya and some areas of Yunnan is the most popular. Yang Yang, general manager of Beijing Spring and Autumn Travel Agency, said that at the beginning of this year, many tourists chose to go to Sanya for "continuous recuperation", and most of these tourists were "Yangkang" tourists from North China. Spring and Autumn Tourism has also developed a variety of tourism products suitable for "Yangkang" treatment and recuperation, which directly boosted the recovery of cross-provincial tourism this year.

　　Opportunities and challenges of restarting outbound travel

　　Recently, for the tourism market, it can be said that there are frequent good news. First, it is pointed out in the government work report that restoring and expanding consumption are given priority. Increase the income of urban and rural residents through multiple channels. Stabilize bulk consumption and promote the recovery of life service consumption.

　　On March 10th, the Ministry of Culture and Tourism issued the Notice of the General Office of the Ministry of Culture and Tourism on the pilot resumption of the travel agency’s business of China citizens’ outbound teams to relevant countries (the second batch). According to the circular, starting from March 15th, 2023, the national travel agencies and online travel enterprises will be resumed on a pilot basis to operate China citizens’ outbound group tours to relevant countries (the second batch) and "air tickets+hotels" business. From now on, travel agencies and online travel companies can carry out preparations such as product release, publicity and promotion. List of countries involved in (the second batch of) outbound group tours: Nepal, Brunei, Vietnam, Mongolia, Iran, Jordan, Tanzania, Namibia, Mauritius, Zimbabwe, Uganda, Zambia, Senegal, Kazakhstan, Uzbekistan, Georgia, Azerbaijan, Armenia, Serbia, Croatia, France, Greece, Spain, Iceland, Albania, Italy and Denmark.

　　According to the survey results of CBN’s "Consumer Recovery, Will You Buy in buy buy", 32.37% of the respondents plan to travel both domestically and abroad this year. In other words, at least one-third of the respondents have the willingness to spend on this year’s outbound travel.

　　At the beginning of February this year, a number of outbound team tours started, mainly in the Southeast Asian market. The major overseas tourism bureaus have also started marketing for the China market in the near future. For example, the National Tourism Administration of Thailand originally planned to attract 5-6 million China tourists to Thailand this year, but after seeing the recent upsurge of China tourists’ enthusiasm for traveling to Thailand, it immediately raised its expected target. "In 2019, the number of tourists from China visiting Thailand was about 11 million, accounting for about a quarter of the total tourists in Thailand. According to the current good recovery momentum, we have raised our expectations. We now expect 7 million to 8 million China tourists to travel to Thailand this year." Yutasa, director of the National Tourism Administration of Thailand, recently revealed in an interview with the First Financial Reporter.

　　At the same time, Tourism Dubai, Tourism Australia, Tourism New Zealand and Tourism Singapore are all getting together for promotion.

　　"The further relaxation of outbound travel will inevitably play a positive role in the recovery of the tourism market this year. But we must also see the challenges faced by the recovery of the outbound travel market. For example, compared with domestic travel, outbound travel needs to go through a series of procedures, which are different according to the requirements of different countries, and some visa reservations need to be queued. Three years later, the local docking personnel in many outbound destination countries have also undergone great changes. For example, many local Chinese restaurants in Europe and America have switched to other formats, so it is very difficult to make a group meal of Chinese food now, and it is necessary to find a local catering business again. Local tour guides should also be re-docked. Moreover, many hotels in Europe have to book half a year or more in advance, and it is not easy to get a lot of rooms at once. The route of outbound group tour should also be redesigned, and the conflict between Russia and Ukraine has also led to various cost increases in some European tourist destination countries. International flights have not fully recovered, and these factors will make it take some time for some long-distance outbound travel in Europe and America to recover. To restart the docking of ground connection resources, we can foresee that the prices of some outbound travel products may double due to fewer flights and rising local costs. " Gu Wei, assistant general manager of Shanghai Airlines Tourism Group, spoke bluntly to the First Financial Reporter.

　　According to the questionnaire results of CBN’s Consumer Recovery, Will You Buy in buy buy, 57.39% of the respondents’ per capita spending budget for a single trip this year is 10,000-20,000 yuan, while 32.6% of the respondents’ per capita spending budget is 5,000-10,000 yuan. Judging from this, the per capita spending budget of the consumers interviewed this year is not low, even higher than in previous years.

　　Tourism enterprises pay attention to creating scenes and recruiting talents again.

　　In view of the positive recovery of tourism consumption this year, major tourism enterprises, scenic spots, hotels and other operators are gearing up. After three years of epidemic, most of the tourists are very sober and professional in this process &mdash; &mdash; Pure low price does not attract too many consumers, but to create attractive and cost-effective products.

　　"In the past, when people talked about tourism, especially group tours, it seemed that the cheaper the better, and this once caused many tourism disputes. Now what we see is that consumers are also mature, and everyone’s requirements for high cost performance of products are prominent. So what we need to do is to integrate the resources of scenic spots and major tourist destinations, and work with them to create some new products that meet the needs of consumers. This year, we will have plans to cooperate with some regional tourist attractions or local tourism-related operators to develop projects. We can participate in investment or act as operators, instead of the past travel agencies blindly serving as organizers to send tourists. " Liu Ning, director and president of Shanghai Jinjiang Tourism Holdings Co., Ltd., revealed in an interview with China Business News.

　　This is also confirmed in the questionnaire survey of CBN’s Consumer Recovery, Will You Buy in buy buy? In the questionnaire, what elements can promote consumption? Most respondents said that it was not low price, but high cost performance accounted for 93.9%, high-quality goods accounted for 90.85%, and value-added space accounted for 86.47%. It can be seen that the goods with high cost performance are the ones that consumers are most willing to spend money on, while the low price factor accounts for only 4.93%.

　　The Shanghai Tourism Industry Association revealed to the First Financial Reporter that in order to make more subdivided products and cost-effective products, it is necessary to pay attention to the creation of derivative scenes of Dawen Travel. For example, in the past, tourism was purely a trip, but now many tourism products can be combined with catering and culture, and some high-quality immersive experience projects and script projects can be created as consumption scenes of Dawen Travel. Of course, this kind of project development needs the cooperation of professional planning and cultural tourism resources.

　　Nowadays, Ctrip, Tongcheng Travel, Mahoneycomb, etc. are all strengthening cooperation with tourism destination resources, hoping to gather offline scenic spots, accommodation and other partners for common development. For example, recently, Tongcheng Travel announced that it intends to acquire Tongcheng Tourism at a total cost of no more than 700 million yuan. This is an attempt and layout of one-way travel in the leisure tourism and holiday market under the background of strong recovery of the tourism industry. At the end of December last year, Tongcheng Travel announced that it would acquire Tongcheng International Travel Service and promote the deep integration of its tourism and holiday business. The proposed acquisition of Tongcheng Tourism is a continuation of Tongcheng Tourism’s leisure tourism and holiday market. If this intentional acquisition can be achieved, it will effectively supplement and extend the existing business of Tongcheng Travel and deepen the control over the upstream core resources.

　　It is noteworthy that due to the three-year epidemic, some travel agencies and upstream and downstream partners still face problems such as resource shortage, and they urgently need support from traffic, technology, data and capital to seize the new opportunities of industrial rejuvenation. How to jointly promote the development of digital intelligence in the industry is a problem that should be considered.

　　In addition, the talent plan is also worthy of attention. Many tourism industry feedback, three years since the epidemic, many tourism practitioners have changed careers, this year’s consumption recovery, tourism recovery process needs a large number of professionals to help, which requires recruiting suitable candidates from college graduates and mature talents. Just recently, 10 companies, including Ctrip, announced the joint launch of the "Travel Mulan Plan", which plans to provide more than 20,000+jobs for women in 2023. Sun Jie, the co-founder of the plan and CEO of Ctrip Group, said that this move is to better meet the business growth demand in the first year of tourism recovery, and at the same time help more women get equal opportunities for development in the workplace.

　　Cheng Chaogong estimates that domestic tourism can be restored to 70% ~ 80% in 2019 this year, while Southeast Asia tourism in the outbound tourism market may be restored to about 70% ~ 80% in 2019. Of course, everything depends on the actual development of the market.

Text/Li Changfeng Wu Wei China Patent Technology Development Company

In the era of knowledge economy, whether it is the change in the proportion of intangible assets among the 500 companies in the Standard & Poor’s Index of the United States, or the frequent patent wars on smart phones and a large number of patent acquisitions in recent years, it shows that patents have become an important asset of enterprises, a key factor of production, a protagonist of trade, a sharp weapon of competition, and a source of power to drive enterprises to last forever. By comparing and measuring the scale and quality of patent portfolio owned by enterprises, we can clearly and accurately analyze their technical strength, innovation ability and even competitiveness.

The patent strength rankings based on a series of objectively quantified patent statistical indicators, such as the Wall Street Journal Patent Scorecard, the IEEE Patent Strength Scorecard, and the Thomson Reuters Top 100 Innovative Institutions Ranking, provide a common comparison stage for all kinds of innovative entities at the technical level, which will cause great repercussions after each release. For the public, we can learn about the technology leaders and innovation benchmarks in the industry, while for enterprises, the shortlist is an excellent publicity. The following is a brief introduction to the above three categories of leaderboards based on the public information on the Internet.

I. Patent Scorecard of The Wall Street Journal

(1) Introduction

The Wall Street Journal (WSJ) publishes the technical strength rankings and stock market data of companies and research institutions in a certain industry in the form of PatentScorecard in the financial & investment column every Tuesday, and the same content is subsequently published in the market data center section of the online website of The Wall Street Journal. The patent scorecard mainly focuses on the patents in an industry, and the statistical indicators involve patent authorization, industrial influence, R&D intensity, technical intensity, scientific intensity, etc., and ranks the institutions in an industry according to technical intensity and scientific intensity, and gives the comparative results of patent strength after comprehensively considering the scale and quality of patent portfolio, and the statistical results are updated every 13 weeks. The patent scorecard covers 18 industries, including aerospace and national defense, automobiles and transportation, biology, chemistry, consumer electronics, personal consumer goods, comprehensive industries, electronic devices, energy and environment, food and beverage and tobacco, heavy industry equipment, industrial parts, raw materials, information technology, medical devices and services, pharmaceuticals, semiconductors and communications. While giving the ranking results of patent portfolio, The Wall Street Journal also correlated the patent scorecard data with Dow Jones financial data, and gave the comparative results of the industrial influence, R&D intensity, patent authorization, stock market and the overall level of an industry.

The data of the patent scorecard of The Wall Street Journal is provided by The Patent Board. The Patent Committee actually belongs to ipIQ Company (ipIQ refers to intellectual property, intelligence quota; Now it is renamed ip IQ Global Company), and its predecessor is CHIresearch. Founded in 1968, CHI has been devoted to the research and analysis of scientific and technological innovation indicators, and has created a series of patent indicators, especially the precedent of statistical analysis of patent citations. CHI’s patent index system is introduced and adopted in the American Science and Engineering Index compiled and published by the National Science Foundation of the United States and the Patent Manual in the OECD series of science and technology index manuals. CHI is an absolute international leader in the field of patent measurement, and the patent scoreboard is its distinctive research achievement and has been registered as a trademark. In November 2004, CHI Company was merged and renamed ipIQ Company.

The patent scorecard was first published in BusinessWeek magazine on August 3rd, 1992. Before 2007, the patent scorecard was published in Businessweek and MIT’s Technology Review every year. Since 2007, The Wall Street Journal and the Patent Committee have become partners and regularly publish patent scorecards in The Wall Street Journal in the form of patent portfolio rankings.

In addition to publishing the ranking results of industrial patent portfolio in cooperation with The Wall Street Journal, the Patent Committee also published The Global Patent Scorecard, The Patent Board 500 Scorecard and the University Scorecard.

(II) Main indicators

Patent scorecard indicators include four aspects and six indicators:

1. Quality: including technical strength and industrial influence indicators. Technical strength is the overall evaluation result of an institution’s patent portfolio strength by combining quantity and quality factors, and it is one of the ranking bases of patent portfolio. Industrial influence refers to the influence of an institution’s patent portfolio on subsequent technological innovation, which is calculated by the cited data of patents.

2. Quantity: The index of patent authorization refers to the number of American patents granted in a certain institution during the statistical period.

3. Science: including indicators of scientific intensity and research intensity. Scientific intensity is used to measure the extent to which enterprises use scientific research results to construct their patent portfolios, and it is also one of the ranking criteria of patent portfolios. Research intensity refers to the number of patents whose scientific relevance is higher than the industry average in an institution’s patent portfolio.

4. Speed: innovation cycle index, which is used to measure the old and new degree of the existing technology on which the patent or patent portfolio is based.

Second, the IEEE patent strength scorecard

(1) Introduction

On October 23rd, 2013, IEEE SPECTRUM published the 2013 IEEE (American Institute of Electrical and Electronics Engineers) Patent Power Scorecard. Patent strength scorecard is the result of objective and quantitative analysis of American patents of more than 5000 leading companies, academic institutions, non-profit organizations and government agencies around the world, which involves aerospace and national defense, automobiles and parts, biomedicine, chemistry, communication network equipment, communication network services, computer equipment and storage, computer software, computer systems, comprehensive enterprises, electronic products, government agencies, medical instruments, scientific instruments and semiconductor equipment manufacturing. The patent strength scorecard ranks according to the patent strength index, which comprehensively considers the quantity and quality of the patent portfolio, among which the patent quality is

It is reflected by the indicators related to patent growth, technological influence, technological originality and technological diffusion. As the scale of patent portfolio weighted by quality is adopted as the measurement basis, the technical strength of an institution can be measured as a whole, which is the best barometer to measure the technical R&D and innovation strength of various institutions. The list is published once a year, and the list in 2013 is the seventh release. The 2012 patent strength scorecard list was also published on Forbes website.

The patent strength scorecard is provided by 1790 Analytics. The founder of the company is Dr. Anthony Breitzman, who used to be the vice president of CHI and a world-renowned expert in science and technology assessment. Dr. Anthony Breitzman founded 1790 Analytical Company after he left CHI. Dr Patrick Thomas, head of patent analysis business and Chip D&rsquo, head of business development; Angelo is a former CHI researcher.

(II) Main indicators

The patent strength index in the IEEE patent strength scorecard is a comprehensive index after combining the number of patents and their growth, technical influence, originality and popularity. Its calculation formula is: patent strength index = number of patents × patent growth index × corrected technical influence index × technical originality index × technology diffusion index. Taking the patent strength index in 2012 as an example, the meaning of each parameter is:

1. The number of patents refers to the number of patents granted in the United States in 2012.

2. Patent growth index, which is used to reflect the patent activity of an institution, and then reflect the innovation activity of an institution. The calculation method is: the number of patents granted by an institution in the United States in the latest year (2012) divided by the average number granted each year in the previous five years (2007-2011).

3. The corrected technology impact index reflects the influence of an institution’s patent portfolio on the subsequent technology development. The calculation method is as follows: first, calculate the basic value of the technology impact index, and then correct it according to the self-citation rate (to eliminate the influence of extreme self-citation). The basic value of technology impact index refers to the number of times that all authorized patents of an institution were cited by all authorized patents in the United States in the last year (2012) in the first five years (2007-2011), divided by the average number of times that all authorized patents in the same period and in the same field as the patent portfolio of the institution were cited by all authorized patents in the United States in the last year.

4. The technical originality index reflects the breadth of the patented technology (i.e. cited patents) cited by an institution’s patent portfolio. Generally, improved inventions tend to refer to existing technologies from a single field, while important original inventions tend to combine patented technologies from different fields to form new inventions.

5. The technology diffusion index, also known as the technology popularization index, is similar to the technology originality index, but it reflects the breadth of the patented technology (i.e. cited patents) cited by an institution’s patent portfolio. The greater the technology diffusion index, it means that the patent application of an institution is popular, which has a large impact on the subsequent technological innovation.

Third, Thomson Reuters Global Top 100 Innovative Institutions Ranking

(1) Introduction

Thomson Reuters’s "Top 100 Innovative Institutions in the World" is the ranking result of the most innovative institutions in the world based on a series of patent indicators, which is published by Thomson Reuters Intellectual Property and Technology Division on its website. It has been published once a year since 2011 and has been published three times so far. According to the data of the top 100 innovative institutions in the world in 2013, according to the number of institutions on the list, there are 46 institutions from North America (45 from the United States and 1 from Canada), 32 institutions from Asia (28 from Japan, 3 from South Korea and 1 from Taiwan, China) and 22 institutions from Europe (including 12 from France and 4 from Switzerland). Although China leads the world in the number of patent applications, none of China companies are on the list due to the lack of patent quality and technical influence.

(II) Main indicators

The selection method of Thomson Reuters’s "Top 100 Global Innovation Institutions" is based on four criteria:

1. The total number of patents refers to the number of DWPI(Derwent World Patents Index) basic patents of an institution in recent three years. This basic patent refers to the patent that publicly released a new technology for the first time in the DWPI patent family.

2. The success rate of patent authorization refers to the number of patents published by an institution in the last three years divided by the number of patents authorized in the last three years.

3. The globality of patent portfolio refers to the number of four-party patents owned by an institution. The Quartet refers to China National Intellectual Property Administration, China, the European Patent Office, the Japanese Patent Office and the United States Patent and Trademark Office.

4. Patent influence based on citation refers to the number of times an institution’s patents have been cited by others in recent five years (excluding self-citation).

summary

Comparing the above three rankings comprehensively, the common point is that, while reflecting the scale and activity of innovation through patent quantity data, it is more important to introduce patent quality data such as technical influence, diffusion, originality and globalization to reflect the benefits of innovation, thus truly and reliably reflecting the comprehensive technical strength and innovation ability of enterprises. Patent ranking itself is only a means of comparison and a yardstick to measure innovation output. Its real strength lies in highlighting that innovation is the core factor driving development in the era of knowledge economy. Take the top 100 innovative institutions in the world as an example. For three consecutive years, the listed institutions are better than those involved in the Standard & Poor’s 500 Index in various indicators: the annual share price growth is 4% higher, the market value-weighted sales growth rate is 2% higher, and the new job growth rate is 0.81% higher. At the top of the wave, these listed companies are deducing realistic cases of innovation-driven development to the society with objective and detailed data.

　　BEIJING, May 16 (Xinhua) Title: Guqin producer in Guangxi farmhouse: Going to Taiwan Province to bring his craft back to his hometown.

　　Author Liu Juncong Huang Lijie

　　In a field manor in Liujiang District, Liuzhou City, Guangxi Province, firewood for cooking by the fireside is sizzling. At this time, Wei Xing held a brush and skillfully painted the guqin blank with "big paint" over and over again. This is a natural paint made from plants, and only the traditional guqin production will go through this important process step.

　　Born in 1985, Wei Xing is a guqin producer who has been studying guqin production for more than three years. She studied guzheng in the Conservatory of Music at the university, and never imagined that she would get involved with the guqin one day and become the inheritor of the production skills of this ancient musical instrument.

　　In the 2008 Olympic Games, an ethereal guqin piece "The Legacy of Taikoo" echoed over the "Bird’s Nest" Stadium, attracting the attention of the whole world, including Wei Xing, who just graduated from college. "At that time, I was fascinated by its unique timbre. Before the song of the Olympic Games was played, almost no one knew guqin, and many people would mistake guqin for guzheng, so it was very difficult to learn it. " Wei Xing said.

　　As a last resort, Wei Xing at that time could only teach himself to play guqin with the help of relevant textbooks. With the rapid development of playing skills, Wei Xing became more and more fond of this ancient instrument. In 2015, while visiting relatives in Taiwan Province, Wei Xing met Lin Lizheng, a well-known local guqin producer. This coincidence made guqin completely change Wei Xing’s life.

　　"At that time, I wanted to worship Master Lin as a teacher and learn the production process of Guqin. But master Lin watched a girl film of mine, but he didn’t agree anyway. In the end, it was a long time before the master reluctantly accepted me as an apprentice. After I really got started, I discovered that guqin production is not an easy task. " Wei Xing said.

　　Wei Xing said that the production of guqin should strictly follow the tradition and the process is complicated. Just the process of painting surface polishing needs to be polished step by step and repeatedly by hand. "The key point of this process is not to use force, but to polish it gently. Brothers and sisters joked that they should’ not eat for three days’ before starting polishing, so the intensity is just right. " Weixing laughed.

　　The tedious and boring production process, coupled with the master’s high-standard production requirements, made this girl who had left her hometown once think of giving up. However, an extremely harsh rebuke from the master made Wei Xing’s psychological defense completely collapse.

　　"At that time, I immediately wanted to pack my bags and go home. But then I calmed down and thought about it carefully. If I don’t learn this skill, then this instrument is very likely to be lost in the future. " With the comfort of brothers and sisters, Wei Xing picked up the carving knife again. "Learning to make guqin is also tempering and practicing, which has taught me meditation." She said.

　　Three years later, Wei Xing bid farewell to his master and classmates, and returned to his hometown successfully. Wei Xing, who had a "garden dream" since childhood, rented a farmhouse quadrangle in the suburbs of Liuzhou and engaged in guqin production in a beautiful and secluded environment every day. She said that it takes one to two years to make each guqin. At present, she has completed a number of customized guqin works, and the price ranges from 10,000 yuan.

　　It is understood that the history of guqin can be traced back to the pre-Qin period, and it has a history of at least 3,000 years. Its timbre is low and its aftertaste is long. As a musical instrument with high cultural status in ancient China, Guqin has been a bridge for many scholars to exchange ideas since ancient times, and it is known as "scholars never withdraw their harps and instruments without reason".

　　After years of silence, Guqin has once again attracted the attention and love of China people, and has gradually become one of the teaching subjects in major music colleges in recent two years. "The domestic environment is slowly getting better, and more and more people are beginning to learn about this ancient musical instrument from me. I am glad to see that it has not been forgotten." Wei Xing said.

　　At present, Wei Xing has also opened guqin playing classes for adults and teenagers, so that more people can feel the charm of the voice of the ages. "Everyone likes it very much, and I will try my best to teach them playing skills. I don’t want this instrument to be lost in our generation." Wei Xing said. (End)
