How will the "triple pressure" affect our economy? What do you think of the 5.5% economic growth target set in this year’s (2022) Government Work Report? Where is the space and grasp for further improving labor productivity in China?

On March 9th, Bai Zhongen, member of Chinese People’s Political Consultative Conference and dean of Tsinghua University Institute of Economics and Management, accepted an exclusive interview with a reporter from The Paper (www.thepaper.cn) on the above issues. He said that consumption and investment will see good growth this year, while the growth rate of foreign trade import and export affected by cardinal utility and other factors will decline. The pressure brought by demand contraction and supply shock will continue to exist, and the expected goals consistent with the national conditions should be set for the business development of enterprises.

Bai Zhongen pointed out that setting the economic growth target of 5.5% this year is very aggressive and challenging. He suggested that special attention should be paid to investment and investment projects should be selected. In addition, it is necessary to make precise policies and provide targeted financial and financial support to enterprises affected by factors such as the epidemic.

Regarding the space for improving labor productivity in China in the future, Bai Zhongen said, first of all, we should do a good job in education, especially the basic education of migrant workers’ children, promote enterprises to increase on-the-job training, and let employees create greater value. We should also smooth the flow of the labor market and improve the efficiency of labor resource allocation.

Investment and consumption may grow well, and the growth rate of foreign trade may decline.

The Central Economic Work Conference held last year (2021) pointed out that China’s economic development is facing the "triple pressure" of demand contraction, supply shock and expected weakening. Bai Zhongen said that the "triple pressure" accurately describes the current situation in China.

Talking about the shrinking demand, Bai Zhongen said after taking stock of the economic growth data in the past two years that the growth rate of consumption and investment is lower than that of GDP, and only the export performance is outstanding.

He believes that the performance of consumption this year depends largely on the development of the epidemic: if the epidemic can be well controlled, the impact on living consumption can be reduced, and the catering, accommodation, tourism, transportation and other industries can return to normal, compared with the low base in the previous two years, consumption may achieve better growth. Bai Zhongen also believes that the government-led investment can achieve a relatively rapid growth this year, despite the effective control of the epidemic. As for foreign trade, he said that it may be very difficult to achieve a growth rate of more than 20% this year. As global production gradually returns to normal, the growth rate of foreign trade will be slightly slower than before.

Talking about supply shocks, Bai Zhongen said that some supply shocks are still there. The conflict between Russia and Ukraine has further raised the commodity prices that were already at a high level, which has brought great pressure on the production and operation of Chinese enterprises. At present, the pressure will continue to exist.

Talking about the expected weakening, Bai Zhongen pointed out that the economic growth potential of China at this stage is almost the GDP growth target of 5.5% set this year. It is unrealistic for some enterprises to hope to maintain an 8% growth rate as they did many years ago. They must accept the current development situation of China and adjust their realistic expected targets in time.

At the same time, many uncertainties faced by the external environment will also affect people’s expectations. In this regard, Bai Zhongen suggested that the formation and withdrawal of policies should allow the market more time to digest, and the general tone of "striving for progress while maintaining stability" proposed by the central government will help stabilize expectations.

5.5% is an aggressive growth target.

In 2022, the Government Work Report set the target of China’s economic growth rate at around 5.5% this year. For this goal, Bai Zhongen thinks it is a very aggressive growth goal.

"According to our research and the research of some other scholars, the current economic growth potential, that is to say, when everything goes well, our growth rate is about 5.5%." Bai Zhongen said that at present, China’s epidemic situation still occurs from time to time, and the global epidemic prevention and control is facing great uncertainty, and geopolitical conflicts have added new uncertainties. These have a negative impact on consumption growth, and uncertainty makes enterprises more cautious and unwilling to take risks when making investments.

"In such an external environment, it is actually a very challenging task to achieve a growth rate of 5.5%." Bai Zhongen said that at present, great efforts are needed to achieve this economic growth target, so the target of 5.5% is very aggressive.

Bai Zhongen said that last year’s economic growth showed a trend of high before and then low, which was partly caused by cardinal utility. In the first half of 2020, it was greatly affected by the epidemic, which contributed to the high growth in the first half of 2021. At the same time, in the first half of last year, the issuance speed of local special bonds and infrastructure investment was slow, and it began to accelerate in the second half of last year, which had a time lag effect on economic growth, so it showed a situation of high before and low after.

"This year, we all realized the arduousness of growth and set a target of 5.5%, which requires great efforts." Bai Zhongen said that because the special debt quota has been issued in advance, the growth rate of local government expenditure is increasing, and the investment growth rate has achieved rapid growth in the first quarter of this year. Regarding this year’s macroeconomic policy, he particularly emphasized that infrastructure investment and investment promoted by government organizations should play a certain role when all aspects are under great pressure, so we should pay special attention to investment and choose investment projects.

In addition, Bai Zhongen also talked about the tax reduction and fee reduction policy that will continue to be implemented this year. He said that the survival and development of many enterprises are facing great impact because of the impact of factors such as multi-point epidemic and rising commodity prices. It is necessary to find these enterprises, make precise policies, and provide targeted financial and financial support to enterprises.

To improve labor productivity, we must first do a good job in education.

In recent years, China’s total labor productivity has been continuously improved. In February this year, the Statistical Bulletin of People’s Republic of China (PRC)’s National Economic and Social Development in 2021 issued by the National Bureau of Statistics showed that the labor productivity of all employees in China last year was 146,380 yuan/person, an increase of 8.7% over the previous year.

What room is there to further improve China’s labor productivity? In this regard, Bai Zhongen said that China is not the most developed country, and there is still a big gap between the per capita GDP and the most developed countries, so it has a certain advantage of being late-comer, so the total factor productivity will grow faster than that of developed countries, and the labor productivity will also increase accordingly.

Talking about how to tap the growth space, Bai Zhongen gave three suggestions.

First of all, we should do a good job in education. He said that the growth of human capital is very important for economic growth, in which human capital is divided into two parts: the quality of labor force and the number of labor force that can be put into production. Education level has a great relationship with people’s productivity. Under the current situation of China’s labor market, we should pay special attention to education, especially the basic education for the children of migrant workers. It is necessary to fill the shortcomings and weaknesses in education, increase investment and give better education to the children of migrant workers.

Furthermore, there is still room for improvement in the efficiency of labor resource allocation, especially in the labor market. For example, he said that the development trend of one industry is declining, and another industry has just started, so the labor force should be transferred from the first industry to the second industry. Bai Zhongen suggested that the free flow of labor force should be unblocked to make the labor market run better.

In addition, enterprises should also make efforts to better provide learning opportunities for employees. We should consider making some institutional arrangements to encourage enterprises to provide employees with learning and further education arrangements, enhance the motivation of enterprises to provide skills training and on-the-job learning, and enable employees to become workers who can bring greater value.

　　Henan is an important birthplace and development place of China opera, with splendid and rich opera culture, and is recognized as the "hometown of opera". Historically, there have been more than 60 kinds of traditional Chinese operas widely circulated in Henan. Since 2006, 18 operas, including Henan Opera, Quju Opera, Yuediao Opera, Wanbang Opera and Mulian Opera, have been included in the national intangible cultural heritage list, and more than 30 operas have been included in the provincial list.

　　These non-legacy operas are the products of farming civilization, which have been active among the people for a long time. They are typical representatives of the traditional culture of the Central Plains, bearing rich cultural connotations and historical memories. After the founding of People’s Republic of China (PRC), Henan opera ushered in a new glory, and many excellent works such as Mulan’s Henan opera "Mu Guiying in command", "Chaoyanggou", Yuediao’s mourning for Zhuge Liang, and Quju’s "Juan Xi Tu" emerged, which swept the country.

　　However, with the diversification of people’s leisure and entertainment methods, Henan opera, like most non-legacy operas, is inevitably affected and impacted, and gradually declines. However, after entering the new century, with tenacious vitality and rich historical details, with the joint efforts of the government and the people, Henan opera has regained its vitality and produced a number of excellent works with high ideological, artistic and ornamental value, such as Cheng Ying’s Saving the Orphan, Jiao Yulu, Hongmei in hay cutter, The Soul Girl, the Quju, the Marriage Event and the Yuediao Laozi. In particular, "Cheng Ying Save the Orphan" has been sung from the fields in Henan to the Broadway stage in the United States, and has been performed in more than 20 countries and regions. There are nearly 20 kinds of dramas transplanted in China, with more than 20,000 performances.

　　The key to the success of Henan opera lies in: always adhering to and inheriting the essence of excellent traditional culture, at the same time keeping close to the pulse of the times and real life.

　　Drama Creation: Paying Attention to Little People and Showing Great Feelings

　　In terms of material selection, Henan operas inherit and carry forward the inherent local and grass-roots characteristics, mainly paying attention to and reflecting the daily life of ordinary people, and paying attention to expressing "great feelings" with "little people", reflecting "great times" with "small stories" and presenting "great themes" with "small incisions", highlighting the brilliance of human nature and feelings of home and country in the fireworks, and exerting efforts to show the national spirit and the spirit of the times.

　　Cheng Ying’s Saving the Orphan is a model work. The play was adapted from the Yuan drama The Orphan of Zhao. On the premise of retaining the basic plot of the original play, Cheng Ying, a civilian doctor, replaced the orphan of Zhao as the protagonist, transforming the feud and struggle between nobles into a contest between justice and evil, kindness and cruelty, and explaining the national spirit of righteous people represented by Cheng Ying, such as sacrificing their lives for justice, kindness and justice, honesty and responsibility, tenacity and tenacity. The drama deeply digs and expands the cultural connotation and human nature connotation of the original drama, and looks back on historical figures from a contemporary perspective, realizing the creative transformation from traditional famous dramas to contemporary fine works.

　　Adhering to the creative concept of "attaching importance to small people and showing great feelings", Henan opera also pays attention to depicting characters with vivid and simple life details in English model dramas, reducing lofty and great English model characters to ordinary people, and revealing their life trajectory from ordinary to great, so that English models can be true, credible and sensible.

　　For example, "Red Plum under hay cutter" changes the heroic narrative mode of similar themes in the past, and starts from the small aspects of daily life, showing the course of Liu Hulan’s growth from a lively and childish, frank and stubborn country girl to a staunch and unyielding communist party person in a delicate and true way, and making her short and magnificent life vivid and tear-jerking. Since it was put on the stage, the play has performed more than 2,000 times and has been transplanted by many operas.

　　Expression: keep the old essence and create new programs.

　　On the stage presentation, on the basis of retaining the characteristics and essence of traditional art, Henan opera follows the artistic laws and the requirements of the times and constantly explores new ways of expression. This is mainly reflected in the innovative development of traditional programs.

　　Program is the essence of traditional Chinese opera art, and it is also one of the most eye-catching identity signs of each non-legacy drama. However, the traditional program is extracted from the life of ancient opera artists, which is far from modern life. Nowadays, when it is used in new plays, especially in modern plays, it is often divorced from the plot. How to make the program get rid of the "showy" performance and become a means to shape characters and promote the plot has troubled many modern drama creators. Henan opera is upright and innovative. After artistically treating the characters’ gestures in real life, it creates new programs, which can reflect modern life more flexibly and serve the plot. For example, the "cart-pulling dance" in Li Tiancheng, a village official, the "snow dance" in Chongdugou, and the "flood-fighting dance" in Jiao Yulu, etc., successfully show the specific situation of real life through the recombination and application of traditional program actions; The "paddle dance", "kiln opening dance" and "kiln losing dance" in "The Soul Girl" not only blended the dance elements in the traditional program, but also skillfully integrated into the rural life, which provided a possibility for the diversified interpretation of modern local drama.

　　In addition, Henan opera also boldly carried out the innovation of singing. For example, the musical "Faith" adjusts the singing tone of the traditional qupai, and the male and female voices adopt different modes. On the basis of the traditional qupai, a new qupai with a faster rhythm is created, which gives the audience a refreshing feeling.

　　Mode of communication: keep the main position firmly and use the media skillfully.

　　In terms of the mode of communication, Henan opera attaches great importance to the live performance in rural areas, and actively expands multi-channel and multi-form publicity and promotion to stabilize and expand the audience.

　　Live performance is the most traditional way of communication of traditional Chinese opera, which can bring the audience the most intuitive feelings and experiences, and it still has an irreplaceable position. Henan opera has always paid attention to live performances, and the government and the people hold a large number of multi-level and diversified performances every year. The vast rural areas have always been the main positions for performances because of their broad mass base.

　　In 2008, Henan Province launched a public welfare cultural performance activity of "stage art sent to the grassroots", and adopted the operation mode of "government pays the bill, the troupe performs and farmers benefit", which has been adhered to for more than ten years. Later, relying on this activity, Henan Province launched the "Action of Sending Thousands of Plays to Thousands of Villages to Help the Poor", giving priority to the viewing needs of poor counties and villages, and giving no less than 1,000 performances for the benefit of poor counties throughout the year.

　　With the advocacy and support of the government, some private theatrical troupes, represented by Little Empress Henan Opera Troupe, have long insisted on performing in rural areas. The Little Empress Henan Opera Troupe has performed more than 8,000 performances since its establishment 30 years ago, and nearly 90% of the performances are in rural areas.

　　In addition to guarding the main position of live performance, Henan opera is also actively promoted and promoted through radio, film and television, animation, museums and other ways and channels. After the rise of new media, Henan Opera has used new media platforms, such as opera professional websites, WeChat and Tik Tok, to create more diversified communication channels, which not only broadens the survival and development space of some non-legacy operas and inheritors, but also attracts more young audiences.

　　Take the live broadcast in Tik Tok as an example. According to "2023 Tik Tok Performing Arts Live Data Report Henan", in 2022, the number of live broadcasts of Henan operas increased by 109% year-on-year, nearly twice the increase of the number of live broadcasts of national operas. Among them, Henan Henan Opera has the largest number of live broadcasts among all operas in China, and the number of live broadcasts of rare operas such as Taoist drama, Dapingdiao, Erjiaxian and Sipingdiao has also exceeded one million, and there are many people in the audience.

　　The emergence of a large number of property disputes in urban residential quarters has become one of the important sources of group disputes at the grassroots level in cities, which puts forward a new topic for political and legal organs on how to further improve the ability of urban social governance.

　　The reporter of "Legal Daily" recently learned in an interview in Taizhou City, Jiangsu Province that only in Hailing District, the core city with a population of 550,000, various factors lead to the superposition of property disputes, showing the trend of complaints to administrative organs, a large number of court cases increasing year by year, and group disputes happening from time to time.

　　Since February this year, the Hailing District People’s Court has established a "3+1" property dispute mediation mechanism in cooperation with the Housing and Construction Bureau, the Town Street (Park) and the Residence (Village) Committee, which has grasped the key points of diversified solutions to property disputes. "We insist on putting the non-litigation dispute resolution mechanism in the front, creating a new mode of joint judicial and administrative resolution of property disputes, and achieved good results. In the first half of this year, there were only 45 litigation cases in court, a decrease of 84.32% compared with 287 cases in the same period in 2018. " Jiang Wei, Party Secretary and President of Hailing District Court, introduced.

　　A research report inspires new ideas of common governance and win-win situation

　　Urban property disputes are not only a livelihood issue, but also a social governance issue.

　　As early as November 2017, the Hailing District Court comprehensively sorted out and summarized the continuous high growth of property disputes in recent years, and formed the Trial Report on Property Disputes in Hailing District (2013-2017).

　　According to the report, from January 2013 to October 2017, the hospital accepted 1,936 cases involving property disputes, and the number of cases received increased from 197 in 2013 to 610 in the first three quarters of 2017 alone. The report also sorts out six trial characteristics: small litigation object, diverse forms of disputes, difficulties for owners to prove, and high failure rate of owners. Among them, the cases of property service enterprises recovering property service fees became a batch lawsuit, and the reasons why owners failed to pay property fees on time were mostly due to inadequate public management and untimely, incomplete and irregular services provided by property service enterprises.

　　Although the amount of property disputes is small, once a large number of cases are brought to court, it will often lead to owners’ dissatisfaction with property service companies, which will further aggravate the contradictions between the two sides. In some communities, owners even jointly request to change property companies. In 2018 alone, the District Housing and Construction Bureau accepted as many as 5,000 complaints about property disputes, and there were nearly 10 group disputes caused by property disputes, accounting for more than 10% of all civil and commercial cases in Hailing Court. Liu Zongkai, a member of the party group and vice president of Hailing District Court, believes that court trial is only a palliative, and strengthening source governance through joint administrative organs and grassroots organizations is the fundamental solution. Only by establishing litigation and non-litigation resolution mechanism can we treat both the symptoms and root causes and truly promote the harmony and stability of the community.

　　It is understood that after the relevant investigation report of Hailing District Court received the attention of the leaders of the district party committee and the district government, Xiao Liulin, the deputy head of the district, specifically asked the Housing and Construction Bureau to seriously study, actively dock with the court, and come up with specific measures to resolve contradictions before litigation.

　　Judicial cooperation with administration to create a new model of diversified solutions

　　Under the guidance and promotion of the Hailing District Court, it has jointly issued with the District Housing and Construction Bureau the Implementation Opinions on Joint Resolution of Property Disputes and the Code of Practice for Administrative Mediation of Property Disputes, etc., and comprehensively constructed a "3+1" mechanism for mediation of property conflicts between residential (village) committees, towns and streets (parks), housing and construction departments and judicial trials, so as to achieve layered diversion and step-by-step resolution of contradictions and disputes, and ensure that minor problems do not leave the community.

　　On June 25 this year, after more than three months of trial operation, Hailing District Property Dispute Mediation Center was formally established, and the District Housing and Construction Bureau sent two full-time mediators to be responsible for the administrative mediation of property disputes in the whole region. At the same time, 146 community mediators were selected in the whole district to mediate property disputes in their communities in time. Complex disputes that cannot be mediated by grass-roots mediators shall be transferred to the mediation center for joint mediation by full-time mediators and courts, and those that still cannot be mediated shall be transferred to proceedings.

　　"Administrative mediators are familiar with the property management of each community. The mediation scheme they provide is more in line with the objective reality, and even some problems left by developers can be solved by the way. Such mediation can often be done, and both parties can be satisfied. " Judge Gong Xiqin, the property dispute trial team of Hailing District Court, said.

　　"Under the guidance of the judge, we have successfully mediated 161 property disputes since the mediation studio was in operation for three months, and only 20 of them finally entered the proceedings." Yuan Ruiqin, the mediator, said, "In the process of mediation, we also grasped the focus and problems of property conflicts in various communities, which provided effective information for the Housing and Construction Bureau to carry out administrative work and improved the accuracy and effectiveness of the work."

　　"The establishment of the center is also the first in the whole province. This is a new measure for the benign interaction between the government and the hospital in the new era. It can effectively integrate the administrative and judicial forces, solve the contradictions and disputes in property management in a diversified way, and achieve reconciliation, harmony and the rule of law." Zhang Zhaoyang, deputy secretary of Hailing District Committee, said.

　　Insist on people-oriented and establish a new mechanism of source governance

　　It is understood that the Hailing District Court put forward the concept of "people-oriented, source governance" to the district party committee and district government, and suggested standardizing property management behavior, reducing contradictions from the source, fundamentally resolving contradictions, and speeding up the construction of the social governance first good area and the people’s livelihood happiness pilot area.

　　According to this suggestion, the Hailing District Party Committee and District Government promulgated the Ten Norms for Property Management in Hailing District, Detailed Rules for Standardized Assessment of Property Management, Pilot Work Plan of Party Construction and Property Management, Relevant Publicity Measures for Property Management Areas, and Work Plan for Audit of Property Fees, thus forming a new pattern of multi-integration, such as grass-roots organization leading by Party construction, open and transparent service finance, autonomous management of community owners, inspection and evaluation of housing and construction departments, diversified solution of contradictions and disputes, and full guarantee of judicial services.

　　"In Loudaokou, you can see the service standards, service contents and charging standards publicized on the wall, so that we can consume clearly." Grandma Wang, the owner of Hanlin Yaju Community, praised. "Standardization of property management is a good measure to really make enterprises bigger and stronger. With the owners’ grievances gone, it is not difficult for us to collect property fees." Manager Wang, the person in charge of Yintai Property, said.

　　"On the basis of promoting the openness and transparency of services, we have established a property service ‘ Red and black list ’ Evaluation mechanism, in ‘ Blacklist ’ Property companies that have appeared more than three times in the world will be interviewed for rectification. For property companies that have not changed their education, the street owners’ meeting will start the exit procedure of property projects to ensure that property companies provide quality services in accordance with the contract. " Mao Songyun, director of the District Property Management Office, introduced.

　　In order to support administrative organs to mediate property disputes in accordance with the law, Hailing Court has given full play to its judicial function, and formulated and promulgated the Guide to the Trial of Property Dispute Litigation Cases, which uses the evaluation results of administrative organs on the service quality of property service enterprises as evidence, clarifies the frequently controversial clauses in property service contracts, effectively solves the problem of "difficulty in proof" of owners and the understanding scale of mediators in administrative mediation, and realizes the seamless connection between administrative management and judicial trial.

　　"With the promotion, support and guarantee of Hailing Court, we have more motivation and confidence to carry out administrative work, and the new property management mechanism can be successfully constructed." Liu Fei, deputy director of the Housing and Construction Bureau of Hailing District, said that the complaint rate of owners dropped by nearly 20% year-on-year, and the collection rate of property fees increased by 10%.

　　"The new model of the source management of property disputes in Hailing District Court not only lightens the litigation burden of the parties, but also makes the people have more sense of gain, reduces social contradictions, maintains the harmony and stability of the grassroots, and makes contributions to improving the level of urban social governance." Xu Zhilun, member of the Standing Committee of Hailing District Committee and secretary of the Political and Legal Committee, said. (Reporter Ding Guofeng correspondent Xiao Chen Wu Jiazhen)

CCTV News:Today (November 28th) morning, the main line of the deep-middle passage of Guangdong-Hong Kong-Macao Greater Bay Area core transportation hub, a major national project, was officially completed. The Shenzhen-China Passage spans the east and west banks of the Pearl River Estuary, connects Shenzhen, Guangzhou and Zhongshan, and integrates "bridge, island, tunnel and underwater communication", with a total length of about 24 kilometers. It is planned to be open to traffic in June next year.

The deep middle passage is one of the most difficult cross-sea cluster projects in the world at present. The construction scheme of "West Bridge and East Tunnel" is adopted. The length of the submarine tunnel in the east is about 6.8 kilometers, and it is designed as a two-way eight-lane tunnel, which is the longest and widest submarine steel-shell concrete immersed tube tunnel in the world. The cross-harbour tunnel is connected with two artificial islands, the east artificial island realizes the conversion between the cross-harbour tunnel and various highways on the road surface, while the west artificial island undertakes the conversion function between the tunnel and the offshore bridge.

West Artificial Island: A New Landmark on Lingdingyang, a "Kunpeng at Sea"

Driving in the deep middle passage with a total length of 24 kilometers, how can vehicles safely and smoothly enter the cross-harbour tunnel from a bridge tens of meters high on the sea? The artificial island in the west of the deep middle passage has solved this problem.

Viewed from the air, the West Artificial Island, which covers an area of about 137,000 square meters and is equivalent to 19 football fields, is like a Kunpeng, spreading its wings on the sea of Lingdingyang.

The most important function of the West Artificial Island is to realize the bridge-tunnel conversion. Construction started in December 2016, and it is the earliest project in the whole line. The "first son" of this deep-middle channel falling on the Lingdingyang plays a very key role in the overall stability and progress of the deep-middle channel. The position and function are irreplaceable, but where should we start to build such an artificial island on the vast sea?

Each of the 57 steel cylinders has a diameter of 28 meters and a height of 35-mdash; 40 meters, weighing 650 tons. The west artificial island of the deep middle passage is located in the sand mining area, and the stratum is complex. The construction team developed the core technology of steel cylinder foundation pretreatment, which "grinding bean curd" on the uneven and uneven foundation of the construction sea area, reduced the strength of the hard soil layer, and combined with the self-developed 12-hammer linkage hammer group with the same frequency vibration, successfully drove giant steel cylinders into the seabed rock stratum accurately and firmly, creating a world record for the rapid island formation of the west artificial island in four and a half months.

In addition to realizing the function of bridge-tunnel conversion, the West Artificial Island will also be an important place for the maintenance and management of tunnels and bridges, and this artificial island with the shape of "Kunpeng on the sea" will also become a new landmark on the Lingdingyang.

East artificial island: realizing underwater intercommunication

In order to realize the underwater intercommunication function, the deep-middle passage cannot be separated from the East Artificial Island. So how to switch between island tunnels? How to connect with the adjacent road network on the ground and realize multi-site interconnection? Follow the reporter to the East Artificial Island to continue to understand.

The artificial island in the east of the deep middle passage is located in the south of Shenzhen Baoan Airport, and connected to the submarine immersed tunnel in the west, which is the gateway project of the Shenzhen end of the deep middle passage.

Seen from the air, the T-shaped main tunnel of the East Artificial Island and the ramp tunnel bridge on both sides are like a seabird flying on the sea with its wings. Before construction started in 2017, it was still a shallow sea. The island body filled with sea sand covers an area of nearly 350,000 square meters, which is equivalent to 48 standard football fields.

CCTV reporter Li Weidai:This is a diversion point of the underwater interchange hub of the East Artificial Island of the Shenzhen-China Passage. We are now 15 meters below the sea surface. In front of me is the submarine immersed tube tunnel of the Shenzhen-China Passage. The tunnel divides into two forks here. In the future, vehicles from Zhongshan to Shenzhen will be smoothly connected with the ground road network through this Y-shaped fork.

There are four off-ramp and confluence points like this in the underwater hub of East Artificial Island, which together with the main tunnel on the island realize the diversion and confluence of vehicles.

Underwater interchange is in a relatively closed environment, which has certain influence on driving sight distance. As early as the preliminary study of the project, the professional team simulated driving in various states through professional software system, optimized the continuous partition wall at the confluence of the main line tunnel and the ramp tunnel as a column to increase the permeability, and adopted intelligent electronic safety auxiliary facilities to improve the driving safety.

Reporter’s visit: immersed tube floating installation integrated ship

The submarine tunnel part of the deep middle passage has a total length of about 6.8 kilometers and eight lanes in both directions. The immersed pipe section of the tunnel is connected by 32 pipe sections and a final joint, each of which is 165 meters long, 46 meters wide, 10.6 meters high and weighs about 80,000 tons. How can we float these "Big Macs" in place in the vast sea and install them accurately? It all depends on one core equipment, which is the world’s first immersed tube floating installation integrated ship independently developed by China.

This submerged floating installation integrated ship tailored for the deep middle passage is 190.4 meters long, 75 meters wide and 14.7 meters deep, and its deck area is equivalent to two football fields. It is a special ship for submerged construction of submarine tunnels with the strongest installation capacity, the highest sinking accuracy, the most efficient construction operation and the most advanced performance in the world. Seen from a height, it looks like a huge rectangular steel clip, holding the immersed tube firmly in the center of the ship.

The biggest highlight of the floating and installing integrated ship is that it is equipped with an automatic driving system, which perfectly solves all kinds of difficulties in floating and transporting immersed tubes out of the dock. All immersed tubes of the Deep-Middle Passage need to be docked from Guishan Island Immersed Tube Prefabrication Factory and floated to the immersed tube installation area near the West Artificial Island, which is nearly 50 kilometers long. After seven channel changes, the channel width is only 200 meters, and it passes through the busiest Lingdingyang channel in China, which will face many safety risks in the whole process.

Compared with the traditional pipe joint floating installation method, the integrated ship greatly reduces the dredging amount of the floating channel, which is more environmentally friendly and economical. Through the intelligent driving system, the installation system on the integrated ship will show its talents after the immersed tube is transported to the designated sea area.

Through the display screen, the commander accurately grasps the specific position of the immersed tube on the seabed; At the same time, the attitude of immersed tube is monitored in real time by using dynamic signal acquisition information system. With the close cooperation of several systems, the immersed tube is lowered to the foundation bed to realize the initial docking. Then, with the help of the pressure of seawater, hydraulic pressure welding is carried out, so that the immersed tube butt joint can be seamless. At present, the deep middle channel submarine immersed tube tunnel has achieved the docking accuracy of all pipe joints within five centimeters, with seven pipe joints in a row, achieving millimeter-level accuracy.

"Beidou" Helps Seamlessly Dock 80,000-ton Submerged Pipes with Needles

The immersed tube section of the deep middle passage subsea tunnel is composed of 32 pipe joints weighing about 80,000 tons and a final joint. How to ensure that these pipes can be accurately installed in place at one time on the seabed? Beidou navigation system contributed greatly.

This is the world’s first super-long, super-wide two-way eight-lane steel-shell concrete immersed tunnel. 6.8km long, it is divided into 32 pipe joints and final joints, which are installed step by step, and each immersed pipe weighs 80,000 tons.

First of all, the giant immersed tube should be transported by cable, accurately placed in the foundation groove of the seabed, and then it should be seamlessly connected with the front pipe joint from end to end, and it should be used safely for 100 years.

Under the invisible water, the installation error of 5 cm can be said to be "embroidery with needles" for immersed tubes with a length of more than 160 meters, a width of 46 meters and a height of 10 meters. If the positioning is inaccurate or the accuracy is insufficient, resulting in excessive deviation of pipe joint installation, the project will have to be completely suspended for "fine adjustment".

When the project started, it coincided with the Beidou system being put into use. In order to introduce the power of Beidou, the team repeatedly made thousands of tests and verifications on land, sea and immersed pipes, and finally formed a scheme. The Beidou satellite antenna on board and the nearby reference station cooperated to differentially locate the immersed pipes, with an accuracy of up to millimeter level.

After entering the water, the position and posture of the immersed tunnel under water are clearly displayed on the screen. Beidou’s positioning performance is stable and reliable, which makes the project progress high-quality and efficient.

China’s auto market is so rampant that no corner can be immune to it. Recently, with the intensive exposure of Equation Leopard, the pattern of hard-core off-road market has also begun to brew new changes. Although the so-called hard-core off-road has been replaced by a formalized square box, as a personalized and fashionable market segment, it is still a growth point that can’t be ignored on the road of new energy for automobiles in China. Although the cake is not very big, it is still indispensable.

Hard-core cross-country domestic brands are divided into three parts.

In the current so-called hard-core off-road market, the Great Wall is still a monopoly, after all, it has the advantages of off-road family and first Mover. When the Haval series gradually declined, the tank series kept the leading position in the market segment for the Great Wall, and then the big dog series transplanted with the concept of "square box" also brought a turning point for the Haval brand. It can be said that the hard-core off-road and square box have saved the face of Great Wall Motor.

According to the latest monthly sales data, tank series vehicles occupy the mainstream share of the hard-core off-road market, of which the sales volume in November was 5,397, the monthly sales volume in November was 5,216, and the monthly sales volume in November was 4,790. The monthly sales volume of the three models was basically the same, and the price range spanned 19.98-345 thousand yuan. At the same time, the sales volume of the main box concept in November was 15,376, and the sales volume of the Haval Raptors in November was 11,012. The price of the former is 98,900-124,900 yuan, and the price of the latter is 157,800-188,800 yuan.

The Great Wall has gained a lot in the hard-core off-road market, and it will inevitably attract chasing and intercepting. The biggest fanfare is BYD. At present, BYD’s main hard-core off-road concept is to look up to the brand and Equation Leopard brand, among which Equation Leopard brand has begun to take shape in terms of sales volume. In November, the sales volume of Equation Leopard reached 6,058, and the monthly sales volume of Equation Leopard just listed reached 2,463. The price range of Leopard 5 was 239,800-302,800 yuan. Compared with the tank 300 with the same price, its market performance has been very eye-catching.

In this market segment, there is also a real old gun-Beijing Automobile. As the originator of China’s hard-core cross-country, Beijing Automobile currently owns four mass-produced models, including BJ30, BJ40, BJ60 and BJ80, among which the newly launched model has won market recognition with outstanding cost performance. In November, the sales volume of BJ30 was 6,756 and that of BJ40 was 3,993.

In terms of product layout and vehicle sales, Great Wall, BYD and BAIC have initially formed a three-point world situation in the current hard-core square box market, but this situation is unstable and more variables may appear in 2025.

Value-oriented electrification promotes market change

With the transformation of new energy sources in China, even the hard-core off-road market, which is extremely personalized, has undergone drastic changes. The so-called hard-core is formalized, and light off-road, square box and new energy have become the main selling points. Therefore, the threshold for entering this market segment is getting lower and lower, which means that more brands and products will enter this market segment.

In addition to emphasizing the square box identification of appearance, new energy and intelligence have become the mainstream development direction. In addition to the tank 300, the tank series are all equipped with the Hi4-T off-road super hybrid system, and the Equation Leopard series models are all equipped with the DMO super hybrid off-road platform. Even for Beijing Auto, the BJ series has been launched with the magic nuclear power drive version.

Hard-core cross-country used to be an area for high-end players, so the price was on the high side. With the addition of China brand, the price of hard-core cross-country vehicles has gradually declined, and the price and sales volume are obviously inversely proportional. At present, the price of high-end hard-core off-road vehicles is about 300,000 yuan, while the price is about 100,000 yuan. The square box that only sells the appearance is especially popular with consumers. For example, the starting price of Haval Dog is 98,900 yuan, and the monthly sales volume exceeds 15,000.

Therefore, under the big pattern of new energy reform, more products will enter the low-end hard-core off-road market, and the main selling points are still the personalized square box appearance and the new energy and intelligence of China brand. Chery’s iCAR brand is obviously aimed at carving up this cake. The starting price of pure electric drive is 109,800 yuan, and the sales volume in November is 4,719 vehicles, so the starting price is 99,800 yuan, and the price threshold is further lowered. Although Chery has not yet become a climate in this market segment, it is still ambitious in terms of its product strategy.

Of course, BYD is still the biggest threat to Great Wall’s leading position. Equation Leopard brand has frequently exposed Equation Leopard Titanium 3 in the near future, and this model may bring great variables to the market segment in 2025. Judging from the information known at present, Titanium 3 is a compact pure electric SUV, which continues the tough appearance of Equus. Pure electric drive brings excellent power performance, while L2 intelligent assisted driving and exclusive drone platform have become the outstanding selling points of Titanium 3 in its class. It is reported that titanium 3 is expected to be listed before June 2025, and the estimated price is 150,000-200,000 yuan.

Write it at the end

If time goes back ten or even five years, when it comes to hard-core off-road, Mercedes-Benz G, Land Rover, and will inevitably be mentioned. However, at present, this position has been gradually replaced by tanks and Equation Leopard. Although the popularity and popularity have made hard-core off-road tend to be formalized, this does not prevent more consumers and brands from enjoying it. After all, in the current automobile market, sales volume is more important than tonality.

　　CCTV News:In layman’s terms, cross-border e-commerce means "buying" and "selling" the world online. At the Central Economic Work Conference held at the end of 2023, it was put forward that it is necessary to accelerate the cultivation of new kinetic energy of foreign trade, consolidate the basic disk of foreign trade and foreign capital, and expand intermediate trade, service trade, digital trade and cross-border e-commerce export.

　　In 2023, the import and export of cross-border e-commerce increased by 15.6%.

　　In the past 2023, cross-border e-commerce has become a highlight in China’s foreign trade field. According to customs data, in 2023, China’s cross-border e-commerce import and export was 2.38 trillion yuan, an increase of 15.6%, of which exports were 1.83 trillion yuan, an increase of 19.6%.

　　The cross-border e-commerce ecosystem is accelerating.

　　At present, China’s cross-border e-commerce sales network covers more than 220 countries and regions around the world, and there are more than 200,000 independent cross-border e-commerce stations. The number of overseas warehouses exceeds 2,400, covering an area of over 25 million square meters. Third-party service providers such as logistics, payment and express delivery serve hundreds of thousands of customers around the world.

　　More than 400 garment enterprises in Tianmen, Hubei Province "ride the clouds" to the sea.

　　Textile and clothing is the traditional pillar industry of Tianmen. There are more than 10,000 clothing business entities in the city, most of which are mainly oriented to the domestic market. With the integration of cross-border e-commerce into the local clothing industry, more and more enterprises have seen business opportunities hidden overseas.

　　In Tianmen, there are more and more clothing enterprises aiming at overseas track. Two years ago, the number of local garment enterprises engaged in cross-border e-commerce business was only single digits, but now it has grown to more than 400.

　　At the beginning of the new year, this "cross-border fever" that swept through Tianmen clothing industry continued to heat up.

　　How to seize this opportunity? The local authorities responded quickly. First, the major cross-border e-commerce platforms were invited to promote investment in Tianmen to explain the entry process and operation rules for garment enterprises. At the same time, we will pay close attention to improving the industrial ecology, a cross-border e-commerce industrial park integrating raw material production, garment processing, logistics and warehousing, and the first batch of 100,000 square meters office areas will open before this Spring Festival.

　　Whenever night falls, the courier will box and ship the packages received from various garment factories. The shipment volume of this cross-border logistics station has increased from less than 20 tons per day in 2022 to 70 tons per day today — 100 tons.

　　Counting cross-border e-commerce: small packages open big markets.

　　Through the invisible e-commerce network, small parcels are continuously distributed to overseas consumers. What are the hot items? How do small and medium-sized enterprises stand in the international "C position"?

　　In 2023, 1.83 trillion yuan of goods in China were exported to all parts of the world through cross-border e-commerce, 2.3 times that of five years ago. China’s ancient craft of straw woven tote bag and Taomi water shampoo have become the hearts of European consumers. In overseas cat families, smart cat litter pots and automatic feeders from China have become new favorites. Lithium batteries and solar cells have also become hot items for global buyers to place orders.

　　In 2023, in the top ten list of global shopping App downloads, China e-commerce accounts for half of the country. Behind the list, new opportunities follow. At present, the number of cross-border e-commerce entities in China has exceeded 100,000, extending from central cities and provincial capitals to second-and third-tier cities, and the number of comprehensive experimental zones in cross-border electronic commerce has reached 165.

　　It is estimated that by 2025, the transaction volume of cross-border electronic commerce in China will reach 2.5 trillion yuan, which will bring new opportunities for China enterprises and brands.

　　Expanding cross-border e-commerce exports and cultivating new kinetic energy of foreign trade

　　Cross-border e-commerce, as a new foreign trade format with the fastest development, the greatest potential and the strongest driving effect, is becoming an important development trend of international trade. All localities are also introducing affordable policies, increasing support and seizing this new opportunity.

　　Shanghai supports the joint construction and sharing of overseas warehouses, and encourages small and medium-sized enterprises of cross-border e-commerce to rent overseas warehouses to "go out to sea"; Chengdu took out "real money and silver" to attract cross-border e-commerce "chain owners" enterprises; Hangzhou encourages cross-border e-commerce enterprises to strengthen intellectual property protection; Suzhou encourages all localities to develop cross-border e-commerce industry organizations and supports the establishment of different forms of industry groups.

　　Policy support, accelerated layout of upstream and downstream enterprises, and cross-border e-commerce "going out to sea" continue to expand new channels. Looking forward from the starting point of the new year, the mobile package is an opportunity to share China’s big market, and it also contains the future of China’s close connection with the world.

　　China news agency, Beijing, January 28 th: Reunion of Taiwan Province youth Spring Festival: I hope cross-strait exchanges will be smoother

　　China News Service reporter Zhang Xiaotong

　　This year’s Lunar New Year is a reunion year that many people have been looking forward to for a long time. Taiwan Province youths who have worked hard in the mainland for many years have returned to Taiwan for the New Year and reunited with their relatives and friends. In an interview with a reporter from China News Service, they expressed their expectation that cross-strait exchanges will be smoother and more convenient in the future.

　　Zhang Yuzhong: Reunion with family and tasting hometown food

　　Zhang Yuzhong, from Taichung, Taiwan Province, is a "drifting north" youth. Two years ago, due to the epidemic, he stayed in Beijing for the Spring Festival. This year, he finally had the opportunity to return home to reunite with his family.

　　"We will post Spring Festival couplets, set off firecrackers, send red envelopes, and go to the temple for a walk, but the New Year’s Eve may be a little different. For example, in Taiwan Province, we will eat a dish called mullet roe, which is a unique food." Zhang Yuzhong said that during the Chinese New Year in Beijing, he would also have an appointment to eat Taiwanese food with friends, but the feeling of returning to his hometown to taste local food is still irreplaceable.

　　On New Year’s Eve, Zhang Yuzhong had dinner with relatives and friends at home and enjoyed a hard-won reunion. During the Spring Festival holiday, he traveled with his family. "Actually, I want to stay at home longer, but my mother is a little ‘ Be in a panic ’ Then go out for a walk together. "

　　In Zhang Yuzhong’s view, this year’s Spring Festival is particularly strong and has a sense of "global Chinese reunion". Not only did he fly back to Taiwan Province from the mainland, but many of his childhood friends also returned to their hometown for the New Year from the United States, Canada or other places, so it was rare for everyone to get together.

　　"It feels really different, plus the weather in Taiwan Province is very good, and everyone gets together and the atmosphere is great." He said that after the holiday, he would stay in Taiwan Province for a while, and then he would return to the mainland to continue his work. "I hope the flight will be smoother then," he said.

　　Guo Xueyun: I found interesting differences in wrapping red envelopes for my parents

　　Guo Xueyun, a "Taipei girl", finally returned to her family this year after several years of Spring Festival in Beijing. "It is always very happy to see my family, which is a familiar feeling. I will also go to see what convenience stores are selling in Taiwan Province and what restaurants are popular now."

　　Guo Xueyun’s flight back to Taiwan Province during the Chinese New Year was generally smooth, but because many Taiwan Province friends who worked in the mainland chose to go back to Taiwan for the Chinese New Year, the price of flights between the two sides was higher.

　　"Because my family is not a very traditional family, that is, everyone has a meal on New Year’s Eve." Guo Xueyun said, however, this year she specially wrapped a red envelope for her parents to show her filial piety.

　　"I found it very interesting that in Taiwan Province, we would give red envelopes to our parents, but it seems that this is not the case in mainland China." She also communicated with her friends and found that it is a common practice in Taiwan Province to wrap red envelopes for others after work, and to express her feelings to the elders. However, in mainland China, red envelopes seem to be mostly given to the younger generation.

　　Guo Xuejun also said that there is a strong atmosphere of Chinese New Year in Taiwan Province. During the Spring Festival, many shops are closed, there are many firecrackers outside, and the New Year’s Eve dinner is more abundant than usual.

　　She also observed some changes, including meeting more people talking about their work and life in the mainland on the street, and visiting the night market will also find vendors selling mainland snacks.

　　After the holiday, Guo Xueyun will return to Beijing. "Cross-strait relations are very close, so the demand for exchanges is also high." She said that she hopes that there will be more opportunities for young people to communicate with each other in the future, and that there will be more flights to make it convenient for everyone to travel and go home.

　　Huang Baixiang: I hope that the warm Spring Festival will be smooth.

　　Huang Baixiang, who works in financial leasing in Beijing, returned to his hometown of Kaohsiung in the New Year. He is very excited. "I am working in the mainland, and I am very happy to come back to see my parents and experience the taste of Taiwan Province. My family is also very happy to see me."

　　"The weather in southern Taiwan Province is warmer and the annual flavor is very strong. I will go to the temple during the New Year ‘ Bye bye ’ Wait. Like my family, I will also have dinner together and watch TV programs. In fact, it is quite similar to the mainland. " Huang Baixiang said.

　　Besides reuniting with his family, Huang Baixiang also met many old friends when he returned to Taiwan Province this time. "Many friends in Taiwan Province are asking when they can go to the mainland, including travel, work, etc. I see that many people are looking forward to cross-strait exchanges." He said.

　　Huang Baixiang also told reporters that the flight back to Taiwan Province was more tense and the ticket price was higher than before, but the ticket purchase process was smooth. "I hope that more flights can be opened in the future to facilitate the round-trip between the two sides. It is always a good thing to communicate and communicate more conveniently. "

CCTV News:Affected by cold air, some parts of the north have strong winds. According to meteorological monitoring, there are 7 ~ 9 gusts in central Inner Mongolia, northern Ningxia, Shanxi, western Henan, western Hebei, western Beijing, western Liaoning and central Shandong, and the local wind power reaches 10. Why is the gale in the north so strong this time? When will the gale last? Let’s look at the analysis of experts from the Central Meteorological Observatory.

Chen Tao, chief forecaster of the Central Meteorological Observatory:Generally speaking, cold air is more active in autumn and winter, which is prone to windy weather. This round of windy weather has a wide range and strong intensity, and the wind in some areas is extremely extreme in North China and Huanghuai. This time, the cold air force affecting our country is relatively strong, and there are cyclones developing in Bohai area, which will cause a large pressure gradient between high and low pressure, which will cause the air to flow in a large range and form windy weather; The second reason is that today (October 9), the turbulent mixing at high and low altitude is relatively strong and the wind speed at high altitude is relatively high. This turbulent mixing will also lead to further increase of the wind near the ground; The third feature is that there will be some valleys or canyons in some parts of North China and Huanghuai areas, which will cause the narrow tube effect of fluid and further accelerate the airflow, forming local strong winds. Today is the strongest day under the influence of windy weather, mainly concentrated in the area from North China to Huanghuai, especially in Beijing, Tianjin, Hebei, Henan and Shandong, where the wind is still relatively strong, and there will be 5 ~ 6 winds generally, and the gust wind can reach 9 or even 10 or more. On the 10th, cold air continued to move eastward, and windy weather mainly appeared in parts of the eastern part of Northeast China.

Xu Wen, Special Reporter of Light: Professor Song, after you returned to China in 2000, you worked in Changchun Institute of Optics, Fine Mechanics and Physics of Chinese Academy of Sciences (hereinafter referred to as Changguang Institute) and established a research team to study the basic physical problems of rare earth nano luminescent materials. In 2007, you returned to your alma mater, School of Electronics, Jilin University, and your direction changed to focus on nano-luminescence and photoelectric devices. What makes you have such a unique academic track? What factors have had an important impact on your research orientation and academic direction?

Song Hongwei: Academic transformation should not only consider the change of academic microenvironment, but also take into account the development trend of macro environment. First of all, as far as I am concerned, I have to adapt to the changes in the academic environment. When I worked in Changguang Institute, my department was the Key Laboratory of Excited State Physics of Chinese Academy of Sciences (now the State Key Laboratory of Photonics and Applications), and my research direction has always been the "orthodoxy" and "mainstream" of the laboratory. After coming to Jilin University, my laboratory is the State Key Laboratory of Integrated Optoelectronic, and its academic orientation is fundamentally different from the previous laboratory, so adjusting the academic direction is an inevitable choice to adapt to the new academic environment. It’s like a player moving to a new team. If he doesn’t change his style to adapt to the new tactical system, he will risk being reduced from a main player to a bench player. On the other hand, the study of rare earth luminescence and spectroscopy that I have been engaged in began in the 1960s, and it is a somewhat ancient subject. I have always compared it to a classical beauty, and beauty is beautiful, but there are some vicissitudes on her face. For example, CRT and PDP display technologies have always occupied the main position in the display field in the last century, but in this century, with the prosperity of liquid crystal display, they gradually withdrew from the historical stage, and the corresponding rare earth CRT/PDP fluorescent materials naturally lost their original market. If I stick to the countryside in my research, it is tantamount to Don Quixote riding a burly horse and holding a pike to challenge the windmill. After several generations’ efforts, the School of Electronics of Jilin University has formed a traditional advantage in the research of optoelectronic devices.Such as orGaNic electroluminescent devices, gan semiconductor light emitting devices, etc. When I lay out and plan my academic direction, I should not only consider the knowledge background and research foundation of my team, but also consider absorbing the essence of the Institute of Electronic Technology for my study and use, and also consider the differences and complementarities with its existing direction. Based on these factors, I position my team’s academic direction as a new type of nano-semiconductor (such as perovskite) light-emitting and photoelectric devices based on rare earth doping.

Xu Wen, a special correspondent of "Light": Lead halide perovskite materials have recently become the star materials in the photoelectric field. In 2017, you first reported the rare earth-doped lead halide perovskite luminescent materials in the world, which solved the problems of low efficiency and small absorption coefficient of actual quantum cutting luminescent materials; You further used it to improve the efficiency of solar cells, and broke the highest record of efficiency improvement [Ref. 1-2], which caused great repercussions at home and abroad. Why did you think of such a topic? What are your expectations for the future development of this material, and what challenges will the next research face?

Song Hongwei: Quantum-tailored luminescence is a physical concept put forward in 1970s. It refers to a nonlinear luminescence process in which a luminescent substance emits two photons in cascade from a high-energy state through an intermediate state (which can be real or imaginary) under the excitation of high-energy photons. In theory, the quantum efficiency of luminescence can reach 200%. At first, the driving force of research mainly came from finding efficient mercury-free fluorescent lighting materials and PDP display materials. In the 1990s, some scientists proposed to apply quantum clipping luminescence (mainly 988 nm luminescence of Yb3+) to crystalline silicon batteries to improve their photoelectric conversion efficiency, and the research in this field continued until the new century. However, the previous research has not found an ideal material that can be applied. The main reason is that people have been trying to achieve this goal by using the energy transfer process between rare earth ions (such as Pr3+ and Yb3+, Tb3+ and Yb3+), which is restricted by the small absorption cross section and narrow band of rare earth ions 4f-4f transition. In 2013-2014, I also arranged a doctoral student to study the quantum tailoring luminescence between Tm3+-Yb3+ and Er3+-Yb3+ in NaYF4 matrix, but I soon realized the problem and voluntarily withdrew from the position, because I didn’t find a strategy to solve the problem at that time. In 2017, we realized the doping of rare earth ions in CsPbCl3 quantum dots, vaguely feeling that its absorption cross section is high, phonon energy is low, and the energy band is basically matched with Yb3+.(More than twice the transition energy of 7F5/2-7F7/2), have you found the only thrill? So I asked Zhou Donglei, a doctoral student at that time, to try, and this attempt actually succeeded. The material we invented can efficiently convert photons in the ultraviolet to blue light region (300-450 nm) to the ideal response region of crystalline silicon battery, successfully avoiding the energy loss of the battery caused by thermal effect, and improving the photoelectric conversion efficiency of the battery by 20%, far exceeding other fluorescence conversion technologies, comparable to the laminated battery technology, and its method is simpler, cheaper and quite practical. As Professor Gamelin of Washington University, who followed us in the related research, said in the special comment of Science (April 22, 2019): "For solar energy conversion, this combination of materials is almost exactly what you want". Because of this, Professor McGehee of Stanford University, an authoritative scientist in the field of perovskite research, commented: "This is one of the most exciting results I’ve seen in a long time". Personally, I think it is a pity that such a nearly perfect fluorescence conversion material and technology is buried in the laboratory and discarded.I hereby call on this research to attract the attention of the domestic government, capital and photovoltaic industry, and push it to industrialization as soon as possible with the joint efforts of many parties. If we don’t have such a strategic vision, although we are original, we will gradually be surpassed by the United States (it took Gamelin research group only one and a half years to follow our results, attract the attention of American academic and business circles, win prizes, get fund support and even register a company). If it is a challenge, this is the biggest challenge we are facing at present. Of course, on the road of industrialization, we will also face problems such as how to solve the stability of materials and how to realize large-scale, large-scale and low-cost preparation, but these are just stepping stones in the way forward.

Xu Wen, a special correspondent of Light: In 2020, you realized rare earth ion electroluminescence in perovskite nanocrystals for the first time [Ref. 3]. What do you think is the future prospect of rare earth electroluminescence in perovskite nanocrystals, and in which industries will it stand out? What difficulties will it face?

Song Hongwei: In the past, there was a view that rare earth ions were not suitable for electroluminescent materials. The main reason for this is that the luminescence of rare earth ions mainly comes from 4f-4f transition, with low spontaneous emission rate and long luminescence life. Under the action of electric field, due to the continuous collision between injected carriers and lattice, the non-radiation transition process of materials will be intensified, which will cause the luminescence quenching of rare earth ions. In 2020, we took CsPbCl3:Sm3+ quantum dots as the luminescent layer and adopted an inversion structure, which initially realized the electroluminescence of rare earth ion Sm3+ in perovskite, and its luminescent color can be effectively controlled from red light to white light. The direct result of this work is to provide a new idea for the field of quantum dot LED(QLED) lighting and display to obtain different colors and stable luminescence through doping. Considering that rare earth ions have rich transitions, especially in the near-infrared and mid-infrared regions, such as Er3+, Tm3+, Pr3+, etc., which are beyond the reach of perovskite bulk materials, and these emission wavelengths are just in the optical communication window, if effective electroluminescence can be realized, it will undoubtedly have very important application value. At present, the electroluminescence of perovskite-doped rare earth materials still faces two major difficulties: the first difficulty is the common problem of electroluminescence of perovskite materials-the stability problem, especially to solve the device failure caused by ion migration under the action of electric field, which is a huge challenge. The second difficulty is the low radiation transition rate peculiar to rare earth ions.In fact, let’s review the development history of organic electroluminescence, which is earlier than QLED luminescence. It is not difficult to find that in the early work, the electroluminescence research of rare earth complexes and precious metal complexes was neck and neck, and even rare earth complexes electroluminescence was more popular because of its narrower emission line and higher color purity. However, because of its low radiation transition rate, it gradually lags behind precious metal complexes in luminous efficiency and brightness. In the electroluminescence of rare earth doped perovskite materials, this problem still exists and can not be ignored. So how to solve this problem? In fact, the research in the fields of surface plasmon physics and microcavity structure design and preparation has made rapid progress in recent 10 years. With the help of this achievement, we can improve the radiation transition rate of rare earth ions through local light field regulation, thus solving the problems of low radiation transition rate and fluorescence quenching under the action of electric field.

Xu Wen, a special correspondent of Light: You switched from rare earth luminescence research to perovskite solar cell research around 2014. In just a few years, you have published many heavyweight papers in related fields, especially in solving the stability and spectral expansion of perovskite solar cells [Ref. 4-6]. What unique advantages do you think can be brought to materials and devices by doping, spectral conversion and heterogeneous combination of organic and inorganic materials? What are the research limitations or technical bottlenecks to realize practicality or industrialization?

Song Hongwei: By December 2020, the best photoelectric conversion efficiency of certified single-junction perovskite solar cells has reached 25.4%, while the efficiency of perovskite and monocrystalline silicon laminated cells has exceeded 29%, which has made rapid development. At present, the primary problem that restricts the industrialization of perovskite is not the photoelectric conversion efficiency, but the long-term stability of perovskite batteries and the cost of preparation and use. Because perovskite materials are seriously degraded under the conditions of water, oxygen and ultraviolet light, the service life of devices is greatly limited. This year’s key special plan of the Ministry of Science and Technology supports the research plan of perovskite solar cells with a service life of 10,000 hours, which shows how urgent and important it is to solve the service life problem for practical application. In the past, our research on solving the life problem of perovskite battery mainly focused on the following three aspects: first, the ultraviolet light in the solar spectrum was converted into visible light by fluorescence conversion to improve the illumination stability of solar battery; second, the tolerance factor and structural stability of perovskite materials were improved by doping rare earth ions and transition metals; and third, the water transport structure was introduced into perovskite battery through the design of carrier modification layer to improve the water resistance of the device. Up to now, the reported photoelectric conversion efficiency of the battery is 22.16%, and the long-term service life can reach 5000 hours. In the research of improving the photoelectric conversion efficiency of perovskite batteries, we have been committed to achieving this goal by expanding its spectral response range to the infrared region.One method is to convert infrared light, which is difficult to be used by traditional perovskite materials, into visible light, which is then used by perovskite batteries. However, this method is limited by the luminous efficiency and absorption cross section of upconversion materials and can only be realized in concentrator batteries at present. Another method is to introduce organic heterojunction with infrared response into perovskite battery to expand the spectral response range. At present, we can extend the spectral range of this laminated battery to 950 nm, and the photoelectric conversion efficiency can reach 21.55%. Although this has reached the best level of research on p-i-n battery at present, it is not an ideal result due to many factors. The ideal result at least exceeds the efficiency of single-junction perovskite battery. It should be said that the concept of this battery is advanced, but there are still many problems to be solved on the way forward. In the future, the stacked structure of perovskite and organic heterojunction is likely to be another very important stacked battery besides silicon and perovskite, because it may not only break through the efficiency limit of perovskite single-junction battery, but also have significant advantages in flexibility and wearable devices.

Hao Zhendong, reporter of Light: Mr. Song, you have been studying the up-conversion luminescence of local Light field for many years, especially in your work published in Light in 2020 [Ref. 7], which makes the up-conversion luminescence of rare earth increase by four orders of magnitude by using cascade effect; Through the core-shell structure design of upconversion nanocrystals and further combination with perovskite, multi-wavelength narrow-band near-infrared detection is realized. The selective detection of wavelength is realized by frequency modulation excitation. Can this design and control strategy be extended to other rare earth luminescence systems? What new ideas and opportunities do you think the new rare earth luminescent and perovskite composite devices can provide for the development of selective narrow-band photoelectric detection materials?

Song Hongwei: Rare earth ions are rich in species and energy levels, and have produced rich transitions, from deep ultraviolet region to mid-infrared region. In fact, the coupling of rare earth ions with perovskite and other semiconductor photoelectric materials may produce many unexpected results in photoelectric detection. For example, by using the coupling of rare earth ions with 4f-5d transition, such as Ce3+, Pr3+ and Eu2+, with perovskite and other semiconductor materials in high energy state, a new photoelectric detector or high-energy scintillator detector with super-strong solar blind zone deep ultraviolet detection capability and even super-strong high-energy ray detection capability can be developed; Using the rich infrared transitions of some rare earth ions and their coupling with some emerging photoelectric materials (such as Er3+, Ho3+, Tm3+, etc.), many new types of narrow-band infrared photodetectors with special bands can also be developed, which have important applications in military and national defense fields. Rare earth is an important strategic resource in China, and it is also an important research treasure house. With the saturation of traditional research fields and the advent of the information age, the focus of future rare earth research and application development is likely to gradually shift from the traditional fields of magnetism and optics to the photoelectric field. Here, I hope that our younger generation of rare earth researchers will seize the opportunity, get out of the solidified thinking, bravely move forward and March into the unknown field.

Hao Zhendong, reporter of Light: Teacher Song, can you share with young scholars how to become an excellent researcher based on your research experience?

Song Hongwei: This is a matter of different opinions. First of all, I want to say that I am a person who "follows my feelings". My hobbies in college were writing poetry and playing chess, and my academic performance was only in the middle, so I don’t think my experience may have universal reference value for young people. Here I would like to share some spiritual things: a person’s life is a long journey, and so is the road to scientific research. Many times, when we walk, our hearts are confused and our steps are confused. So I said, to be an excellent researcher, the first thing is to "persist": persist in learning new knowledge and an ignorant curiosity. Nie Luda, a Chilean poet, said: "I will always walk on the sandy shore, between the mud and the foam. Although the climax will erase my footprints and the waves will blow away the foam, my heart will always be with the ocean and the sandy shore." The heart of our researchers is to be with science forever. Secondly, as an excellent researcher, you should have full confidence. Our ancient Li Bai said, "I am born to be useful" and "If I go out laughing, will my generation be Artemisia?". Our poet Kitajima said, "I tell you, the world, I don’t believe it. Even if there are 1000 challengers under my feet, I will be the 101st". Newton, a scientist, said, "Give me a lever, and I will move the whole earth." I hope our young scholars will always believe in themselves and believe that they can create great miracles in science and technology. Finally, the avenue is invisible, the sound is loud and the sound is loud, and all the laws of nature,Are hidden in darkness and shadows, just like dark matter. Therefore, as an excellent researcher, we should spread our wings of thought, just as Mr. Dai Wangshu wrote in his poem: "I think, so I am a butterfly. After ten thousand years, the light call of a small flower will shake my gorgeous wings through a dreamless and wakeful cloud."
