Do not forget your initiative mind benefits the people and takes the people as the center.

  "The people are only the country, and the country is better." "Governing the country is regular, and benefiting the people is the foundation." The people are the masters of history and the fundamental force to promote development.

  From the people, for the people, rely on the people. The Communist Party of China (CPC) is a Marxist political party, whose fundamental purpose is to serve the people wholeheartedly. In the course of more than 90 years’ struggle, the Communist Party of China (CPC) has never forgotten its fundamental purpose and worked hard to benefit the people.

  The Fifth Plenary Session of the 18th CPC Central Committee put forward the idea of "adhering to the people-centered development", which embodies Marxist historical materialism and the Communist Party of China (CPC)’s fundamental purpose of serving the people wholeheartedly.

  “以人民为中心的发展思想”,核心是“以人民为中心”。对此,最高领袖总书记在诸多场合予以强调。

  把人民放在心中最高位置

  “人民对美好生活的向往,就是我们的奋斗目标。”2012年11月15日,最高领袖在当选中共中央总书记后首次与中外媒体的见面会上,便以这样深情的话语表达了他对人民的感情。

  “中国梦归根到底是人民的梦”“让老百姓过上好日子是我们一切工作的出发点和落脚点”“把人民放在心中最高位置”“坚持以人民为中心的创作导向”……可以说,“以人民为中心”始终贯穿于中共十八大以来治国理政的理论和实践中。

  2015年10月,中共十八届五中全会通过了《中共中央关于制定国民经济和社会发展第十三个五年规划的建议》,指出必须坚持以人民为中心的发展思想。

  此后,在省部级主要领导干部学习贯彻十八届五中全会精神专题研讨班、中央财经领导小组第十二次会议、中共中央政治局集体学习、中央全面深化改革领导小组第二十三次会议、网络安全和信息化工作座谈会等多场重要会议上,以人民为中心的发展思想,被反复提及。

  People-centered development thought, hit the floor, led the development of China during the 13th Five-Year Plan period and even in the future.

  The Supreme Leader made an important speech at the celebration of the 95th anniversary of the founding of the Communist Party of China (CPC), pointing out that it is our Party’s unswerving goal to lead the people to create a happy life. We should conform to the people’s yearning for a better life, adhere to the people-centered development idea, focus on safeguarding and improving people’s livelihood, develop various social undertakings, increase the adjustment of income distribution, win the tough battle against poverty, ensure people’s equal participation and equal development rights, make the fruits of reform and development benefit all people more fairly, and make steady progress towards the goal of realizing common prosperity for all people.

  Analysts believe that the people-centered development thought put forward by the Fifth Plenary Session of the 18th CPC Central Committee is the value requirement put forward by the Party for the overall economic and social development at the top design level, and "people-centered" is the value core of the new development concept.

  Reflected in all aspects of economic and social development.

  Adhering to the people-centered development thought is not only a major theoretical issue, but also a major practical issue.

  The Supreme Leader pointed out that the people-centered development thought is not an abstract and abstruse concept, which can not only stay in words and stop at ideological links, but also be reflected in all aspects of economic and social development.

  In fact, adhering to the people-centered development thought is the Communist Party of China (CPC)’s unswerving pursuit since the founding of the Party. Especially in the new thought and practice of governing the country since the 18th National Congress of the Communist Party of China, the value orientation of people first and people’s livelihood is always running through.

  For example, the report of the 18th National Congress of the Communist Party of China listed "upholding the people’s dominant position" as the first basic requirement for winning a new victory in Socialism with Chinese characteristics under the new historical conditions, the outline of the 13th Five-Year Plan took "upholding the people’s dominant position" as the first principle that must be followed, and the Fifth Plenary Session of the 18th Central Committee incorporated "sharing" into the new development concept. The CCP put forward the "four comprehensive" strategic layout, emphasizing the building of a well-off society in an all-round way, and must not let difficult areas and people fall behind; To deepen reform in an all-round way, we must constantly enhance the people’s sense of gain; To govern the country in an all-round way according to law, we must strive to make the people feel fair and just; To strictly manage the party in an all-round way, we must maintain the advanced nature and purity of the party and constantly strengthen the flesh-and-blood ties with the people.

  In concrete practice, no matter the innovation-driven and energetic reform measures, or the overall planning of urban and rural areas, regions, economic society and the development of two civilizations; No matter how to control environmental pollution, conform to people’s expectations for a good ecology, or pay attention to internal and external linkage development, make a big cake and divide the cake more fairly … … All these fully demonstrate the value orientation of "people-centered" and are the concrete embodiment of adhering to the "people-centered development thought".

  Thoroughly implement the concept of shared development

  How to implement the "people-centered development thought"? An important aspect and approach is to thoroughly implement the concept of shared development.

  The supreme leader pointed out that the essence of the sharing concept is to adhere to the people-centered development thought, which embodies the requirement of gradually realizing common prosperity.

  "In the process of building a well-off society in an all-round way, adhering to the people-centered development thinking, we must take the realization of people’s happiness as the purpose and destination of development, so that all people can have more sense of gain in building and sharing development." Cai Fang, vice president of China Academy of Social Sciences and member of the faculty, analyzed that.

  In Cai Fang’s view, the way to share the fruits of development with the people requires both the government’s efforts to provide more and more adequate public goods and services and the establishment of the necessary incentive mechanism, so as to gather people’s wisdom as widely as possible, stimulate people’s strength as much as possible, and truly achieve joint construction and sharing.

  Adhering to the people-centered development thought puts forward new and higher requirements for leading cadres at all levels, which requires them not only to grasp profoundly in thought, but also to actively practice in practice, and to effectively solve practical problems that people are most concerned about, such as education, employment, pension, medical and health care, social security, etc., so that comprehensively deepening reform policies and measures can truly become measures to solve problems for the people and benefit them, so that the fruits of reform and development can benefit all the people more fairly and practically.

Cesium content significantly increased. TEPCO announced the first round of data on the discharge of nuclear polluted water into the sea.

On September 12th, local time, according to the information released by Tokyo Electric Power Company in official website, as of 12: 15 noon on the 11th, the first round of discharge of nuclear polluted water from Fukushima Daiichi Nuclear Power Plant ended, with the cumulative discharge of 7788 cubic meters in the first round.

Tokyo Electric Power Company said that after relevant confirmation and equipment inspection, the second discharge will start as early as the second half of this month, and it is estimated that about 7,800 tons of nuclear polluted water will be discharged into the ocean.

According to official data, at present, more than 1.3 million tons of nuclear contaminated water containing radioactive substances have been accumulated at the Fukushima Daiichi nuclear power plant, and it is still increasing at the rate of 100 tons per day. It is estimated that in the future, Japan’s nuclear polluted water will be discharged into the sea for at least 30 years.

Affected by the earthquake and tsunami in 2011, the cores of Units 1-3 of the Fukushima Daiichi Nuclear Power Plant in Japan melted down. This is one of the most serious nuclear accidents in the world so far. After the accident, Tokyo Electric Power Company continued to inject water into the containment of Units 1 to 3 to cool the reactor core and recover sewage.

There are three main sources of radioactive wastewater from Fukushima nuclear power plant in Japan: the original coolant of the reactor, the newly injected water for continuous cooling of the reactor core after the accident, and a large amount of groundwater and rainwater that infiltrated into the reactor.

One year after the Fukushima nuclear accident, in March, 2012, Tokyo Electric Power Company first measured the composition and concentration of radioactive substances contained in nuclear polluted water. The results at that time showed that there were as many as 64 kinds of radioactive elements with excessive concentrations.

Of these 64 radioactive elements, 21 have a half-life of more than 10 years, and some nuclides have a half-life of more than a thousand years.Carbon -14 and iodine -129 are the most harmful to human beings and marine life. The half-life of carbon -14 is about 5370 years, and the half-life of iodine -129 is even longer, about 15.7 million years (important data are shown in bold).Carbon -14 will accumulate in marine organisms, that is, fish, and the abundance or concentration of carbon -14 accumulation may be 50 times that of tritium.

On September 1st, Tokyo Electric Power Company of Japan announced that after the Fukushima nuclear polluted water was discharged into the sea, the Japanese side detected radioactive tritium for the first time in seawater sampled near the discharge port on August 31st. However, TEPCO claimed in the notification that the concentration of tritium was "completely safe".

The concentration of radioactive tritium in the seawater sampled this time is 10 Bekkerel per liter. According to the report, the staff set up 10 sampling points in Fiona Fang, 3km away from the Fukushima Daiichi nuclear power plant. The seawater from which tritium was detected this time was taken from the sampling point closest to the discharge port. The concentration of tritium in the seawater sampled at this sampling point on 24th was 2.6 Bekkerel, and the conventional analysis at that time did not reach the detection limit.

As for the sharp rise of tritium concentration in just a few days, TEPCO admitted that this was caused by the discharge of nuclear polluted water into the sea, but they insisted that this concentration was "completely safe".

In addition, Tide News reporters combed the monitoring data released by official website of TEPCO, and found that the content of cesium -137 detected in the water intake of units 1~4 was significantly higher than before.

Cesium -137 is usually one of the products of nuclear energy reaction, nuclear explosion or nuclear accident, which is harmful to human body because it emits beta particles and gamma rays. These rays can interact with human tissues and cause cell damage.

Chen Xin, a researcher at the South China Sea Institute of Oceanography, Chinese Academy of Sciences, once pointed out in an interview that from the perspective of diffusion path, Japanese nuclear pollution will affect the South China Sea, the East China Sea, the Bohai Sea and the Yellow Sea in China. The North Pacific is one of the seriously polluted areas. In fact,The world can’t escape the influence of Japan’s nuclear polluted water.

During the diffusion of radioactive elements in Japan’s nuclear polluted water, radioactive nuclear elements will not only stay on the ocean surface. "It can be said that the ocean is polluted in three dimensions." Chen Xin said that the ocean is a layered system because of the different temperatures and salinities in the upper and lower layers. For example, pouring a little oil into a glass of water is equivalent to forming a two-layer system, and it is difficult for oil to enter the lower layer. But in the ocean, through the "ocean transport belt" and the vertical water exchange process, the oil originally located in the upper layer can also enter the deep layer.

As early as 2021, the team of Academician Zhang Jianmin and Associate Professor Hu Zhenzhong from the Institute of Ocean Engineering of Shenzhen International Graduate School in Tsinghua University established the diffusion model of radioactive substances at the ocean scale from macro and micro perspectives respectively, and realized the long-term simulation of the Fukushima nuclear wastewater discharge plan.

The macro-simulation results show that the nuclear waste water will reach the coastal waters of China 240 days after discharge, and will reach the coast of North America and cover almost the whole North Pacific after 1200 days. Subsequently, the pollutants spread rapidly along the American coast to the South Pacific under the action of equatorial currents, and on the other hand, they transferred to the Indian Ocean through the northern Australian waters.

It is worth noting that although the pollutant discharge location is near Fukushima, with the passage of time, the high concentration area of pollutants will extend eastward along the 35°N line, and spread from the sea near East Asia to the sea near North America. On the 2400th day, the southeast coast of China was mainly light pink with low concentration, while the west coast of North America was basically covered with red with high concentration.

"The impact of nuclear polluted water entering the sea is not only reflected in the ocean current system, but also in the biological system. Through the cumulative effect of the food chain, radioactive substances will eventually enter the human body through seafood such as fish and shrimp." Chen Xin said.

At Syria’s request, Russian troops have been deployed. Former senior US officials: We can’t just mean to use force against Syria.

  CCTV News:The reasons for the air strikes against Syria by the United States, Britain and France are nothing new, and they are related to the "chemical weapons attack". Moreover, the "accusation of chemical weapons attack" happened just when the government forces won a key victory.

  On April 12, a group of Russian military vehicles entered the town of Donggutaduma, which was once controlled by Syrian opposition forces, through the Wafidin Pass. The Russian military said on the same day that the Syrian government has completely controlled the town of Duma. This marks the recovery of the eastern suburbs that threatened the security of the capital Damascus from the opposition in the past six years. For the Syrian government, this is a crucial victory of great significance.

  Just five days before this, on April 7, local time, a video of a chemical attack released by Syrian opposition people began to spread rapidly on the Internet. The opposition accused the Syrian government of using chemical weapons in the Duma, killing at least 40 people. This accusation was quickly echoed by western countries. On April 8, US President Trump said in Twitter that the fighters should "pay a heavy price" and point the finger at the Syrian government, Russia and Iran. On April 10, at the UN Security Council, the United States, Britain and France, which supported the Syrian opposition, jointly submitted a draft resolution on the issue of chemical weapons in Syria, while the Russian side, which supported the Syrian government, submitted two, and the three drafts were not passed.

  United States Permanent Representative to the United Nations Heili"The United States is determined to see the cruel people who dropped chemical weapons on the Syrian people pay the price. You have heard what the President of the United States said about this. During the meeting, even as we speak, important decisions are being weighed. "

  Nie Bianjia, Permanent Representative of Russia to the United Nations"We have conveyed this message to the US through relevant channels, and launching military action against Syria under fabricated excuses may lead to serious consequences. At the request of the legitimate Syrian government, the Russian army has been deployed. "

  Iran is also cheering for Syria. On April 12, the assistant of Iran’s Supreme Leader Ayatollah Ali Khamenei made a surprise visit to Damascus, where the clouds were gathering, and met with Syrian President Bashar al-Assad, saying that Iran would stand shoulder to shoulder with the Syrian government.

  Ali akbar, Assistant to the Iranian Supreme Leader"We will stand shoulder to shoulder with the Syrian government and resolutely counter the aggression against our country."

  In the Middle East, it is well known that Iran sends weapons through Syria to support Hezbollah in Lebanon. It is reported that the air strike target of the United States includes a target of Hezbollah in the rural area of Homs, Syria.

  Former CIA Director Urzay: "I think if the United States can’t just understate the use of force, there are many military facilities in Syria, and there is no reason not to kill them all. Some of them belong to Hezbollah in Lebanon, which is a terrorist organization. "

  However, the US military attack on the Syrian government was also questioned by its allies. At present, there are two main fronts in Syria. One is the eastern front of Damascus, where a suspected chemical attack occurred. The other front is in northern Syria, where Kurdish forces supported by the United States compete with Syrian opposition forces supported by Turkey.

  At present, in Mambiji, the northern front line, Kurdish armed forces are resisting 4,000 Syrian opposition armed forces supported by Turkey. The U.S. air strikes against Syria will endanger the Kurds, because the Syrian government has previously joined the camp supporting the Kurds in the north.

  Kurdish armed commander Golde: "If the Americans are targeting the Syrian government, Turkey will have the opportunity to attack us, which is a betrayal of us."

Ada: I need an award. I will definitely play Dapeng’s Sewing Machine Band.

Ada’s new work "Make a scene in Tianzhu" was released on the first day of the New Year.


                                                              Video/Ren Jie Editing/Yu Chang Photography/Yang Nan Writing/Li Xiye


Special feature of 1905 film network After more than ten years of debut, Ada has gradually become a familiar host for the national audience and transformed from a host to an actor. Although he has acted in dozens of film and television works, Ada is still modest and enterprising when it comes to the identity of an actor.


In the interview, Ada said that he needed a masterpiece and an award. "I hope to be recognized by the industry so that I can announce loudly: Hey, I am an actor." At the same time, she is not in a hurry. "I won’t force myself to play a role that is particularly unlike me. I haven’t reached that skill and temperature yet."


Ada’s style is still sexy this time.

Ada said that he regarded opportunities as life. His friend Dapeng wrote in the book that when he was a newcomer, he made a program with Ada. Ada’s hard work moved him. In Pancake Man, Dapeng also used movies to let the audience see the helplessness of Ada’s efforts but being misunderstood.

In the interview, Ada revealed that he would also join Dapeng’s new film. Recently, when Dapeng announced in Weibo that the second film "Sewing Machine Band" was about to start shooting, Ada also said, "I want to go back to your 16-year-old and see that packed concert." Let people look forward to the spark of this good friend in the new movie.

The flame of the main Olympic torch is as high as eight meters, which can’t be extinguished by heavy rain.




  With an unprecedented fireworks feast at the opening ceremony of the 2008 Beijing Olympic Games, Chinese conquered the world with gorgeous fireworks last night, and the audience was amazed by the wonderful fireworks shapes. Zhao Weiping, the commander-in-chief of the Olympic opening ceremony "Bird’s Nest" and the Great Wall fireworks display implementation team, was excited and talked to reporters about the unknown story behind the fireworks.

  No paper scraps


  At 11 o’clock last night, the opening ceremony of the Olympic Games came to an end. The audience was surprised to find that there was not a scrap of paper or residue left in the fireworks display throughout the opening ceremony.


  Zhao Weiping said that this is because a new type of environmental protection material has replaced the "paper pad pressure chamber" of traditional fireworks, thus ensuring that the fireworks can be completely decomposed and burned out at the moment of lighting.

  No smell of gunpowder


  Last night, when the "Silver Waterfall" with a total length of more than 30 meters flowed down the bowl of the Bird’s Nest, it was as if a Milky Way was injected into the venue, and the passion quickly passed and surged in the venue. Fireworks were just around the corner, but the audience didn’t smell a pungent smell.


  It turned out that the fireworks placed in the Bird’s Nest were not filled with gunpowder, but instead of gunpowder, compressed air was used through the technology of "Shenzhou VI Launch", and the compressed air and fireworks were ejected through electromagnetic valves.

  How does peony bloom?


  The first climax of the "Bird’s Nest" is to interpret the whole process of peony, the national flower, from budding to blooming, and suddenly the Bird’s Nest turns into a red ocean of peony. Zhao Weiping, chairman of the national brand Panda Fireworks Company, said that the blooming process of "Peony Blossom" took only 11 seconds, but the number of fireworks was 4,845.


  Originally, in order to make the whole red peony cover the whole bird’s nest, the designer used computer three-dimensional special effects technology to draw a huge peony covering the roof of the "Bird’s Nest", and then selected 85 points on the roof of the "Bird’s Nest", each of which is responsible for emitting 3 petals, each of which consists of 29 fireworks, which symbolizes the 29th Olympic Games.


  When setting off, according to the order from inside to outside, the "flower heart" is fired, and then the innermost "petal" is fired, and then it transitions to the outermost petal in turn. When the last petal is opened, 85 points are started at the same time to volley fireworks.

  How to transfer the "Olympic rings"


  That night, five circles of five colors, red, yellow, green, black and blue, appeared in the sky, and the five circles were connected with each other, showing the Olympic rings pattern.


  Zhao Weiping introduced that the biggest difficulty in using fireworks to express the Olympic rings and other patterns is that it is difficult to control the initiation point and time interval of fireworks. The interval error of each fireworks cannot exceed 0.03 seconds, and the audience can see the circle and the five rings only when they are fired in series at a constant speed.

  "Silver Waterfall"


  How to flow into the stands


  During the opening ceremony, there was a "silver waterfall" nearly 40 meters long, like the Milky Way, which slowly hung down along the bowl of the "Bird’s Nest" and flowed into the stadium. The "Bird’s Nest" stand immediately turned into a silver hall.


  Zhao Weiping said that the diameter of the bowl of the "Bird’s Nest" is about 500 meters, more than 40 meters above the ground. This shape requires that the diameter of the "Silver Waterfall" should not be less than 500 meters and the length should not be less than 30 meters, so that the audience can be there.

  How does the "dove of peace" spread its wings?


  Careful viewers will find that a pair of snow-white wings were born on both sides of the "Bird’s Nest", flapping up and down, just like a dove spreading its wings and flying.


  Zhao Weiping told reporters that it is not difficult for the "Bird’s Nest" to give birth to "wings". What is difficult is that the wings should be flapped up and down, showing a dove of peace spreading its wings and flying dynamically. In order to make this dove of peace "smart", the researchers first improved the discharge effect of the traditional fireworks element "white tail", which has only white light and no track left by the tail passing through the air, just like the wings of the dove of peace. In order to make the wings move, the researchers calculated the flapping frequency of the flying dove of peace, so that the "Bird’s Nest dove of peace" fluttered its wings once every second on average.

  How does the "Red Flash Bird’s Nest" feel dynamic?


  A red silk thread in the night sky, passing through the "Bird’s Nest", is flashing like a red neon lamp. Under its embellishment, the whole "Bird’s Nest" is flashing, running and jumping.


  Zhao Weiping said that the first difficulty of the "Red Flash Bird’s Nest" lies in the layout. In order to cover the entire "Bird’s Nest", a launching point should be set up every five meters on each main beam; At the junction of the two main beams, a launching point is also set up every five meters, and all launching points are evenly distributed, so that the whole "Bird’s Nest" can jump in the red ocean; The second difficulty lies in the time difference control, and the fireworks at each point must be lit and extinguished at the same time.

  How to open Tianmen


  There was a scene in the opening ceremony: a magnificent arched gate appeared over the "Bird’s Nest". From closing the door and opening a crack to opening half and three quarters until the Golden Gate finally opens. Zhao Weiping said, "Opening the Tianmen Gate" is difficult to measure in the distance and angle between the ground and air. The distance between the first group of emission points and the angle with the horizontal plane must ensure that the emitted fireworks meet in the air and hand over an arch; The distance and horizontal angle between the second group of fireworks must ensure that when the fireworks meet in the air, there is just a gap, just like the door has just opened a gap, and so on. If the angle is a little bit biased, the process of opening the door cannot be vividly reproduced.

  How does the countdown work?


  9, 8, 7 … When the opening ceremony started, the first thing in the air was flashing numbers. Zhao Weiping introduced that the number nine drawn with fireworks stays in the air for no less than one second. As soon as the number nine goes out, it lights up at eight and flashes again for one second. "If the number stays even in the blink of an eye, the fireworks will not draw a countdown stopwatch.".

  The flame is eight meters high.


  Can resist ten winds.


  Olympic main torch


  Secret of combustion system


  Last night, Xu Tong, deputy commander of the torch project for the opening ceremony of the Beijing Olympic Games and director of the dispatching center of Beijing Gas Group, revealed that the flame of the main torch of this Olympic Games was accurate to 8 meters high and 4 meters wide. The main torch can resist 10 winds and 80 mm rainstorm per hour. Because the torch is also equipped with lightning protection device, it can prevent lightning strike and can "turn off without noise"


  The flame height is 8 meters.


  Xu Tong said that the torch of the main Olympic venue consists of three parts, including the torch head, gas pipeline and control system. The key to determine its shape and color lies in the torch burner, which is made up of hundreds of burning holes arranged in rows, grouped and segmented into a disk shape, forming a three-dimensional shape with a height difference of 1.6 meters together, and spiraling up.


  Due to the spiral shape of the torch, there is a height difference of 1.6 meters between the high and low burning points of the torch, which is very different from the flat disc burner of the torch in the past. Xu Tong said that in order to ensure the visual effect of the flame shape of the torch burning, the torch team cooperated with the overall structural modeling in the design to set up the gas supply cavity of the burning device in sections, grouped and combined, and controlled and adjusted the torch burning in sections, so that the flame shape was more consistent with the structure, thus concentrating the firepower to the maximum extent, making the flame shape complete and coherent, and the height reached more than 8 meters, which greatly enhanced the appreciation.


  Rainstorm can’t be extinguished


  In order to improve the rain resistance of the main torch


  Yes, in the design, the researchers increased the gas supply pressure, thus increasing the outlet flow rate of the burner and improving the stability of the flame under bad weather conditions. During the rain-proof test of the burning device, the lighted torch has withstood the test of "artificial rainfall" environment created by six groups of fire-fighting high-pressure water guns, ensuring that the torch still keeps normal combustion in the rainstorm weather with rainfall of 80 mm per hour, which is higher than the rainfall requirement of 60 mm per hour of the Olympic Organizing Committee.


  In addition, in order to meet the wind resistance requirements of the main torch proposed by the Olympic Organizing Committee, the torch design team installed a special wind protection device in the combustion system. The field simulated artificial wind tunnel test shows that the torch has the ability to resist the wind equivalent to 10 winds.


  Gas supply double insurance


  Xu Tong said that all the gas and electrical systems of the main torch of the Olympic Games are designed and installed in a two-way and double-insurance way, which can ensure the normal operation of the torch combustion control system. Power failure all the way will not affect the combustion of the main torch, and even the gas supply is dual-mode.


  It is reported that in order to cooperate with the opening and closing ceremony operation center to complete the torch physical test and realize the mobile emergency gas supply for the main torch, the torch team of Beijing Gas Group organized the design of special pressure regulating equipment for the pneumatic source of large-flow vehicle-mounted compressor, and the compressed natural gas will be used as the emergency standby gas source for the main Olympic venue and other urban areas.

  The 2024 government work report mentioned new energy vehicles many times. The US government recently said that it is "taking unprecedented actions" to deal with the flooding of China cars in the US market, and the new energy vehicle industry has become a hot topic of concern and discussion among the representatives of the two sessions. In recent years, the "new three kinds" of foreign trade represented by electric manned vehicles, lithium batteries and solar cells have continued to be popular, becoming a new growth point of China’s foreign trade exports and forming strong competitiveness. In 2023, the cumulative export of "new three kinds" products was 1.06 trillion yuan, which exceeded the trillion yuan mark for the first time. China has become an important promoter in promoting the transformation of world energy development and coping with climate change. The development of new energy automobile industry is of great significance for reducing pollutant emissions in the transportation field, promoting high-quality peak carbon dioxide emissions, reducing dependence on oil imports, and supporting the construction of a global automobile power. From budding to having the world’s largest new energy vehicle market, complete industrial supporting system and perfect policy support system, China has cultivated and grown a number of outstanding leading enterprises with international competitiveness, and embarked on a "new" road with innovation leading development.

  In 2023, the new energy vehicle market in China grew rapidly, with a sales volume of 9.495 million vehicles and a market share of 31.6%, up 37.9% year-on-year. Among them, new energy vehicles exported 1.203 million vehicles, up 77.6% year-on-year, and production and sales accounted for more than 60% of the global total. According to the forecast of China Automobile Industry Association, the sales volume of new energy vehicles will reach 11.5 million in 2024, which will continue to maintain a steady and positive development trend, showing an increase of more than 3%, which will be a crucial year for China’s new energy vehicle industry to further enhance its global position. From the perspective of development momentum, China’s new energy automobile industry maintains a leading position in technology and rules, which is an important kinetic energy for China’s export, investment and consumption. Judging from the competition pattern, the new energy automobile industry is a highly competitive industry in the manufacturing industry. This year, it will enter a period of deep remodeling, and the concentration of the industry will continue to increase. Improving the competitiveness in an all-round way is the way for enterprises to develop. From the perspective of internationalization, the "trade+overseas production" model will still be maintained, and it will show a rapid growth trend, gradually changing from trade-oriented to overseas investment localization development, which is the basic law of internationalization.

  The development of new energy automobile industry is not only the iterative upgrading of products, but also the innovation of industrial model.-Through the careful cultivation of the domestic consumer market, the huge market demand is transformed into the endogenous driving force for the manufacturing industry to make up the chain and strengthen the chain. After the internal circulation is smooth, it will actively promote the development of the external circulation, transforming the scale advantage of the domestic market into the global market advantage and even the standard advantage of industry development. In the future, it is necessary to expand the leading edge of the industry, promote consumption growth and enhance international influence to support the development of intelligent networked new energy vehicles.

  Expand the leading edge of the new energy automobile industry and maintain the sustained, healthy and controllable development of China’s new energy automobile industry.First, continue to strengthen key core technology research. Focusing on the fields of new energy and intelligent networked vehicles and key components, we will strengthen the forward-looking and leading patent layout and accelerate the core technology research of ultra-high performance car-level AI chips and industrial software. New hybrid technology is the focus of charging technology innovation, and pure tram companies will pay attention to the matching of hybrid technology routes. The second is to strengthen the effective control ability of the whole process of battery recycling. Establish a closed-loop management system for the whole process of power battery use, scrapping, cascade utilization, recycling and dismantling. With the increase in the export volume of new energy vehicles, more and more retired power batteries exported overseas need to be recycled. Retired lithium batteries are high-grade mobile mines. It is necessary to clarify that retired lithium batteries are not solid waste and speed up the improvement of the transnational recycling policy for retired power batteries exported to new energy vehicles. The third is to speed up the construction of intelligent networked new energy vehicle talent team. Encourage leading enterprises to participate in the whole chain of talent cultivation, deeply participate in colleges and vocational education and teaching plans, and provide internship and on-the-job training channels. Broaden and extend the identification of electric and intelligent vocational skill levels, and improve the incentive mechanism for high-skilled talents. The fourth is to deepen the reform of the assessment system of state-owned automobile enterprises. Fuel vehicles and new energy vehicles are in different stages of development, and the technology of fuel vehicles is mature, so the profit is high, and new energy vehicles are still in the growth stage. Therefore, it is beneficial to stimulate innovation vitality and improve market share by conducting a separate assessment of new energy vehicle business for automobile central enterprises, focusing on technological innovation, market share and future development.

  Promote the steady growth of consumption of new energy vehicles.The consumption of new energy vehicles is a new bright spot in China’s domestic demand growth. First, it is necessary to reduce the purchase and use costs of new energy vehicles. Continue and optimize the policies and measures for the reduction and exemption of vehicle purchase tax for new energy vehicles; The electricity consumption of public charging and replacing facilities in residential areas shall be subject to the residential electricity price, and the peak-valley time-of-use electricity price shall be implemented, and the charging service fee shall be encouraged to be reduced in stages. The second is to moderately advance the layout of charging and replacing infrastructure. Accelerate the construction of fast (super) charging and power exchange infrastructure in intercity expressways, install charging infrastructure in public parking lots, and promote the transformation of comprehensive energy stations at refueling stations. Improve the construction level of charging infrastructure in rural areas and residential quarters according to local conditions, and increase the number of rechargeable cars. The third is to implement policies and measures to support new energy vehicles going to the countryside. Promote the accelerated upgrading of automobile consumption in small and medium-sized cities and rural areas, and promote the withdrawal and trade-in of old vehicles. Efforts will be made to improve the carrying capacity of rural power grids. By speeding up the construction of county and township charging infrastructure, we will increase investment in the transformation and upgrading of rural power grids, speed up the expansion and upgrading of distribution networks, and ensure the safe and stable charging of electric vehicles in rural areas.

  Enhance the international competitiveness of new energy vehicles.China intelligent networked new energy vehicles go to sea, which is of positive significance for improving the world environment. The first is experience sharing and standard interoperability. Share experiences with the whole world, especially countries in the south of the world, use China technology to promote affordable electric vehicles to the world, and promote the interoperability between China standards and international standards, so that domestic car companies, charging facilities and third-party operating companies can have unified standards, provide better charging and driving experiences for car owners, and help achieve the goal of controlling global warming in the Paris Agreement. The second is to improve the carbon emission data management system. The EU Regulation on Batteries and Waste Batteries requires that the carbon footprint of power batteries must be declared from February 18th, 2025. It is necessary to improve the carbon emission data management system of power batteries as soon as possible, including accounting standards, industrial chain data, verification and guarantee, etc., so as to provide relevant accounting functions for countries and enterprises and effectively guide the whole industrial chain to jointly reduce emissions. Third, the car companies as a whole cooperate with each other to enhance the brand value of China. Do a good job in quality, safety, technology and marketing service system, instead of "price war", fight "value innovation war". The vicious competition of "price-fighting" will not only damage the operating efficiency of China car companies, but also make overseas markets feel less favorable and welcome to China brands, insist on high quality and good price, and constantly improve the gold content of China-made brands. The fourth is to improve the convenience of RMB cross-border settlement. Encourage banking institutions to expand the scale of cross-border RMB settlement, include new energy automobile enterprises and related enterprises in a higher level of trade and investment facilitation pilot, and simplify business procedures.

Interview with Yin Haijie: What was lost in the renovation of Harbin Daowai Historic District?

Harbin is a city with a history of only over a hundred years. Daowai District is an old city in Harbin, which was formed and developed earlier. It is also a witness to the historical memory of the city. There are not only buildings known as "Chinese Baroque", but also living carriers of Harbin folk snacks, performing arts, business and other cultures.

However, since the first phase of renovation project was started in 2007, Daowai historical block has suffered from blind renovation and tourism development. According to Yin Haijie, a professor of sociology at Harbin Institute of Technology, "the old road in people’s memory has changed its appearance, and the’ soul’ outside the road has been tottering."

About four or five years ago, Yin Haijie began to pay attention to all kinds of problems in the process of renovation of historical blocks outside Harbin. In 2014, he published a paper entitled "Cultural Mourning in the Renovation of Historical Blocks outside Harbin", which bluntly pointed out that "this renovation project, which started with the protection of historical buildings and culture outside Harbin, has gone astray in the complicated and chaotic competition for interests, and cultural protection has become neglected or too busy for all parties.

Nowadays, in the face of the rapid development of urbanization, not only Harbin, but also the protection of historical blocks all over the country is undergoing increasingly severe challenges. Therefore, The Paper (www.thepaper.cn) interviewed Professor Yin Haijie.

The PaperHow did the research topic of the renovation of historical blocks outside Harbin come into your sight?

Yin haijieI have been paying attention to Daowai Historic District for a long time, because it is the earliest developed area after Harbin opened its port. Moreover, I am from Harbin. When I was young, I liked the atmosphere outside the old road, and I often went there for a stroll when I was in college.

Harbin is a city formed by the construction of the Middle East Railway in modern times. In the 1920s and 1930s, the so-called "westernization" and "Europeanization" in Harbin were so fierce that after Zhang Xueliang came here, did he think it was still China? Then he promoted the construction of the Confucian Temple in Harbin, and wrote the Inscription of the Confucian Temple in Harbin.

After the opening of Harbin, China’s national capitalists and foreign comprador fought fiercely in this land, and in the process, China’s national capitalists did not lose to them. One of the most important things to remember is Wu Baixiang. I think he should be a figure in the history of China’s commercial development. He established a shareholder system similar to the present one long ago, and his internal management is very good.

Wu Baixiang founded the famous Tongji Shopping Mall outside the old road. My uncle used to work as a clerk in Tongji Shopping Mall. He once told me that Tongji Shopping Mall’s business area is half that of Lin Qiu Company (a Russian-run shopping mall), but its turnover is twice that of it. Tongji Shopping Mall was a very popular place in those days, and the building was also a "Chinese Baroque" style combining Chinese and Western styles. Originally, there were four mirrors at the entrance, and all passers-by had to take a photo. It was a very important landmark building in Harbin.

Chinese Baroque Architecture

About four or five years ago, I noticed some distressing things in Daowai area. One was barbaric transformation. After the workers came, all the walls were shoveled off. In fact, there were good diagrams and signs on them. Secondly, Tongji shopping mall was demolished, which is a sad thing for Harbin people.

The PaperIs the case of the renovation of the historical block outside Harbin typical in China?

Yin haijie: It should be typical. Nowadays, in the process of urbanization in the whole country, there are actually not many old cities left. I feel that the preservation of historical blocks in urban construction is a particularly urgent task. When I go abroad, in some countries, no one has the right to demolish buildings as long as they are more than 80 years old, regardless of the quality of the buildings themselves. If you want to demolish them, you must get the consent of the parliament.

But now we are very casual. When businessmen come, they can tear it down if they want. Some of them have even been listed as historical protected buildings, but they can still be torn down in some way. For example, Harbin demolished all the sites where the northeast anti-Japanese hero General Li Zhaolin was killed. It is a beautiful small building in itself. So I say that the protection of historical blocks is a very urgent task, but as a scholar, I often feel very powerless.

The Paper: According to your investigation, what forces are there in the process of rebuilding historical blocks outside Daodao?

Yin haijieI think the leading force is the government and developers, or the transformation reflects the will of a more harmonious political and business relationship. In contrast, the power of culture is too weak, and scholars like us just speak. Some old local residents are also ordinary people at the bottom of society. They have neither the right to participate in the renovation of historical blocks nor the possibility to speak out.

Overall, it is dominated by the government and implemented by developers, and the loss of culture becomes inevitable. However, a few years ago, local media and scholars also made some appeals. I am gratified that the large-scale destructive demolition has slowed down.

The PaperIt has been more than two years since your paper was published. Has the situation changed?

Yin haijie: there is basically no big change. Because Harbin wants to transform "Chinese Baroque Street" into a commercial tourist destination, it has been transformed. Now it’s called "repairing the old as before". After the merchants are moved away, the interior is renovated and then the investment is invited. This is basically the mode.

Even so, after re-inviting investment, everyone still likes it very much, because the "Chinese Baroque" building complex itself is very valuable, and the characteristics of combining Chinese and Western are very distinct. It is in contrast with another central street in Harbin, which is completely European-style, and it is two completely different cultural areas. I generally agree with this transformation. Although I haven’t given enough consideration to the loss of culture, at least the building has been preserved now.

Architectural art survived, but the living culture died.

The PaperWhat lessons do you think we should learn from this transformation?

Yin haijieAs a sociologist, I still pay more attention to the cultural characteristics of the city, which are more reflected in people’s life and management methods. Specific to Daowai District, the merchant culture here is particularly developed. Some people say that children outside will sell steamed buns at the age of 4, but this culture is not a solidified thing.

During the transformation, we should investigate all kinds of cultural elements and consider how to keep them in place. For example, food culture, the government should ask developers to find ways to make those small shops survive after the transformation. There are many snacks in Harbin outside the old road, and now there may be less than a quarter left, but even so, it can attract diners from all directions. We all hope that those "small burying shops" can survive. Their frontispiece is very small, and there are only two or three tables when they go in, but the taste they make is delicious. Like this, the government should try to help them keep their original flavor, improve their sanitary conditions and so on, and try to keep it there. But not now, as long as there is no money, you can only move away.

In addition, there are many performing arts cultures in Daowai historical block, such as donkey shadow play, puppet show, etc. Originally, many "circle buildings" walked into it, which was a small stage. We should consider how to keep these in place during the transformation process. I think this aspect is not enough.

I call on government departments to consider culture first, then architecture, and then commerce and tourism in the process of rebuilding historical blocks. Culture must come first, not commerce. At least this thinking logic should be changed.

The PaperCultural protection and commercial development seem to be eternal problems and contradictions in the transformation of urban historical blocks.

Yin haijieYes, in this process, cultural protection is being ignored. Only the government can do this. If the government does not act, cultural protection will become empty talk. I think this is also a very important reason why our country is now "one thousand cities on one side". In the process of transformation, administrative forces often do not consider the value of culture at all.

The PaperAs far as you can see, are there any cases that have been done well in the whole country?

Yin haijieI remember that Kuanzhai Lane in Chengdu should have done a better job.

I have only been to the three lanes and seven alleys in Fuzhou, which gives me the feeling that the facade of the lanes and alleys has only been preserved. Sometimes when the door is opened, there is a clearing, and there are no buildings left, only walls left. Of course, it is not easy to keep it like this, but such buildings are not alive.

Outside the old road, it is a bit like the overpass in old Beijing, and all kinds of performing arts culture are very developed. If the old building of the overpass is still there, but the artists are gone, then this culture will be gone, right? I think cultural protection is imminent.

Because I like the old culture myself, I want to find such a place everywhere, but now it is almost gone. Historical blocks carry cultural memories, but we have destroyed too much in urban construction, especially in the large-scale urban transformation and relocation in the 1990 s. This is our big failure.

The Paper: What about the situation abroad?

Yin haijieI lived in Japan. We know that Japanese cities were badly damaged by World War II, but Nara and Kyoto were well protected. I know a Japanese professor who likes China culture very much. He said that Nara is a small Chang ‘an and Kyoto is a small Luoyang, so he also wanted to visit our Xi ‘an and Luoyang. Later, after I took him to see it, I left in great disappointment. How can I compare with Nara and Kyoto? The historical blocks have been completely destroyed, which is really regrettable. I feel very sorry after reading it for days.

The PaperDo you think there is a conflict between the economic slowdown in Northeast China and cultural protection?

Yin haijieCultural protection can only bring long-term economic benefits, and it can only promote the economy, not lead to economic decline. It is precisely because we don’t pay attention to cultural protection that a city has no culture and vitality and will eventually decline completely. A city with culture will always exude charm.

The following is an excerpt from Yin Haijie’s thesis by The Paper:

In 2007 and 2010, the first and second reconstruction projects of Daowai Historic District were started. The location is the most concentrated and exquisite part of existing Chinese Baroque buildings, namely Jingyang Street, Jingyu Street, Nansidao Street and Nanxun Street. After the second phase of the project, the third phase of the project with a larger area will be started soon.

This massive and time-consuming renovation project has involved many stakeholders, such as the government, developers, residents, old shops and so on, and all parties have started a game from their respective positions. In this interest-oriented game space led by the government and developers, the cultural protection of historical blocks is bound to be distorted. Under the pressure of transformation and the lure of interests, time-honored brands have gradually become "stale", and the interests of residents have nowhere to stretch, so they can only make a living by forbearing. No one has noticed that this renovation project, which started with the protection of historical buildings and culture outside the old road, has gone astray in the complicated and chaotic competition for interests, and cultural protection has become a blind spot that all parties have intentionally ignored or neglected.

First, the old brand: in the gap between the system transition and the wave of development

After several historical changes, some of these old brands have moved away from their original places, some have changed their flags, some have disappeared, and more have been lost under the demolition bulldozers. At present, there are only a few old brands left in Jingyu Street, such as Lao Dingfeng, Shiyitang and Hendry Glasses, but they have all been corporatized. Only a small number of shops still maintain the business model of "front shop and back factory" in the original old house (that is, processing at the back and selling at the front, which belongs to the traditional business model of small workshop).

The author mainly interviewed the traditional time-honored shops and corporatized time-honored shops.

Keeping the traditional time-honored brands often retains the original operation mode of shops and factories in front of them, and the current leaders are still the heirs of the time-honored brands, mostly from the old employees who worked here when they were young, and bought back the state-owned shops after the reform and opening up. Some of the time-honored brands rely on traditional flavor and favorable traffic location, and their business has been very prosperous, especially recognized by some old customers.

In fact, it is difficult for such a time-honored brand to get government support and protection. In addition, because it has changed from a state-owned enterprise to a private enterprise, it still maintains the standard of tax payment when it is state-owned, which makes some shops inefficient. The owner of Donglaishun said this:

"Now I have gone to the old-age pension and the room rate, and there is no big income. The high taxes paid by enterprises like us are all coming from state-owned enterprises, and taxes cannot be avoided. If you don’t want to pay taxes like that, you have to change your brand. If you take this brand off, it will be blind for hundreds of years. "

When the old shops can still be used, most of them are still willing to maintain the status quo and maintain the business characteristics and traditional flavor of the old brands. For example, Donglaishun, Hongguang Wonton Restaurant, etc. However, there are also some well-known Laozi shops that can’t resist the temptation of interests and the pressure of government decrees, and move away from their original places and transform them into modern mass-produced hotels, such as Zhangbaopu and Fanjiyong.

Although these shops have maintained their original flavor in history, their owners often have the conservative consciousness of small merchants, are short-sighted and only care about business. The culture carried by the shops is at most a signboard for their profit, and they do not cherish the culture itself. When the author asked about the history and culture of the time-honored brand, their attitude was very indifferent. The shopkeeper in Laodu replied, "There is nothing to say, just look at the introduction and you will know everything. We will tell you those things."

For the renovation of Daowai block, most shop owners have no concern about culture, but complain that the popularity of Daowai block has dropped sharply due to the renovation of pedestrian street and the cancellation of public transportation.

After the corporatization, the managers and employees of the time-honored shops are uniformly deployed by the superior companies, and most of them are young, and they have no inheritance relationship with the responsible persons in the history of the time-honored shops. The understanding of the history and culture of the time-honored shops only stays in the written introduction, which shows that the vivid history and culture have disappeared. The current manager of Shiyitang is an elder sister in her thirties. She is at a loss about the history and culture of Shiyitang.

Q: "Do you know anything about the history of the World Hall?"

A: "I don’t understand. Look at me, I’m so young and I just transferred here (take me outside the store and just show me the old brand signs and photos of the founders posted in the window)."

Q: "Do you have any inheritance relationship with him?"

A: "No, we are all from Shiyitang Pharmaceutical Company, not the original family type."

Some time-honored brands will retain some traditional techniques and techniques, but it is generally believed that the use of advanced equipment and the standardization of corporate management are in line with the development of the times, and traditional and backward things should be eliminated.

As for the ongoing block renovation here, because these workers are not indigenous residents outside the road, they just come to work here during the day, and they are completely unaware of the block renovation and cultural protection here.

Second, residents and ordinary merchants: in the relocation storm of leaving their homes,

Most of the residents and merchants interviewed have memories of the prosperous period after the end of the Cultural Revolution in the 1970s. In retrospect, a sense of pride as an outsider is beyond words, which is enough to see the splendid past of Daowai, leaving a deep impression on people’s hearts. As for the present situation outside Daoism, most of the residents interviewed think that it is not as good as before, and it is in decline, which is very regrettable. It is very sad that a large number of historical buildings, especially some popular old shops, have been demolished, just like remembering shopping malls. During the interview, several veteran residents said:

Interviewee 1: "How many places have been divided outside this road? Hongqi, Liaohe and Xianfeng Road, which are ceramics and collective strength, are all divided by outsiders. Earlier, our place was quite lively."

Interviewee 2: "This is really a bit extinct. Now there are few old brands outside the road, and the best ones outside the road are the same ones. "

Interviewee 3: "Tongji was the most popular in the early days, but it hasn’t been good since it was finished." Oh, my God, you didn’t even know about the old classmate earlier. Wow, it’s so beautiful. Once you go in, it’s like walking around the stairs. The thing of collecting money is like this. After that, you buy tickets and come back. When I was a child, I loved to go there and look in the mirror when I was finished. "

Interviewee 2: "Tongji’s manager (who stripped Tongji’s shopping mall) should be shot. If there is a classmate now, he can’t even open a shop. It’s a museum, and no one can enter, so he has to put a gun to it. The haha mirror at the door is sold for ten yuan (angry). "

A sea of people’s Tongji shopping mall

The newly-built Tongji Shopping Mall after being demolished has no trace of history (from the author’s field visit and shooting)

In the eyes of these ordinary people, the protection and planning of Daowai historical blocks is a matter for the government, and the people are powerless before the will of the government, so some people express helplessness and indifference. A small tailor shop owner in his fifties said this:

"Now it’s not what ordinary people want. The government has its own plan, and it can do whatever it wants. The ordinary people don’t seem to have any effect. You are looking for residents to investigate now, and you can’t find anything. "

In the interview, the author found that these old residents outside Daodao are very concerned about the housing problem. After understanding, it was found that the government wanted to move the residents here to Qunli (located in the outer suburbs of Harbin) in order to plan the tourist attractions outside Daodao as a whole, because the residents did not want to "change from city people to country people" and unanimously opposed it. Several 60-and 70-year-old Daowai residents complained about the government’s relocation:

"People don’t want to go, so let’s join forces. Where is the collective strength? It seems to be Acheng, far away, going to the countryside. This is not the Cultural Revolution, and people have not made mistakes. This is a good person."

However, the real historical buildings outside Daodao (that is, the "circle building") have extremely poor living conditions after the residents moved out. They are dilapidated due to years of disrepair, and there is no water supply and heating. The aging circuits and wooden structures often cause fires. Among the residents who did not cooperate with the relocation, the young and economically qualified residents abandoned their old houses and left their homeland to buy houses and live elsewhere; The elderly residents who have no economic strength and poor physical strength have to stay in these old houses, and their miserable life has never been asked again. Because of the low rent, most of the idle old houses are occupied by migrant workers who do small businesses, and they usually pay less attention to the use and maintenance of the houses, which aggravates the fire hazard of the old houses. An aunt who lives in an old circle building said this:

"In recent years, the rich are not living here. Nobody cares about this street. It’s all old wires that are always on fire. And the renters here are all from the countryside, and they don’t pay attention. But we have to pay attention, or where to live. "

The current situation of "circle building" in disrepair (from the author’s field visit and shooting)

The old buildings facing the street are covered with traces of fire (from the author’s field visit)

Residents reported that the number of the original residents in Daowai Old Street has been reduced by more than half. After the shops closed in the evening, the merchants who did business also returned to live elsewhere. At night, there was no one in the streets and lanes, which became what people called "ghost towns" and "dead cities".

The basic livelihood of ordinary people has not been solved. How can we talk about the historical and cultural protection of metaphysics? "House" has become the biggest pain in the hearts of the residents here. They have no choice but to regard it as the price that the block transformation has made them bear innocently, so most residents are very disgusted with the protection of baroque buildings here. As for these historic buildings, residents don’t care about their historical and cultural values, and they don’t understand that the government spends a lot of money to repair these impractical buildings.

"If you appeal, just tell us about it, we want to solve the problem of food and clothing, but we want to give us a big house on the spot outside the road. As for anything in their country, we don’t want to know. It has nothing to do with us. It has to solve our problems. "

"What’s the point of protecting it, college students! Some buildings should be torn down, or people will be killed. You can earn money in Gai Lou and solve the difficulties for the residents. You are the whole Baroque, really! My opinion is that we shouldn’t do baroque here. If we repeat it, we should rip it all off and build a tall building. It’ s great, guarding the riverside, you can look at the riverside when you are tall. This building has to sell more pieces. "

"Chinese baroque is no matter how good it is. It is an object left over from history. It is impossible for ordinary people to undertake this matter. You will give ordinary people a spacious house, which is stronger than anything else."

Third, the government and tourism developers: in the joint operation of power and capital,

During the investigation, the author found that all the areas involved in the first phase and the second phase of the Chinese Baroque Block outside Daowai were developed into commercial projects, Erdao Street was building a pedestrian street, and Sandao Street had been developed into a film and television base and a modern leisure area with eight themes.

Zeng Yizhi, a senior reporter and editor of Heilongjiang Daily and a member of the China Cultural Relics Society, summed up the renovation project of Daowai Historical District in his blog post: "The first and second renovation projects of Chinese Baroque moved a large number of indigenous residents to the outer suburbs on the grounds of’ emergency rescue of dangerous houses’ for the sake of overall planning, and moved many old shops away from their original places by means of monetary compensation. The separation of people and houses has forced the original commercial and residential blocks to be changed into commercial and financial land. "

For the original historical buildings, in the first phase of the Chinese Baroque project started in 2007, the plane layout of Nanerdao Street and Nansandao Street, which are within the core protection scope of historical and cultural blocks, was completely changed, some old buildings were demolished and newly built, and the rest buildings were only left with the facade facing the street, and the buildings in the courtyard were completely demolished. The second phase of the project is still repeating the same mistakes. During the implementation process, not only many historical buildings within the core protection scope were destroyed, but also many century-old hutongs were not spared in the construction control zone. Many Daowai residents also expressed their indignation at the government’s massive demolition of historical buildings in interviews:

"This transformation method is wrong. Everything is business and money. What is this called protection? This is making money! We used to be all such buildings outside the road, but now we don’t have them. All the really good ones have been smashed, and now we think of protection. "

For the indigenous residents and shops, as reflected in the above interview, in order to develop commercial projects, the government moved all the indigenous people in this area to the vicinity of the ceramic market near the port authority on the grounds of "reconstruction of dangerous houses". It is understood that in this area, dangerous houses only account for 9.47% of all houses. The merchants are relocated by monetary compensation, but the difference between compensation and relocation is too high, which makes it impossible for those merchants who have been operating here for many years to move back.

However, in fact, the current situation of government investment promotion is not optimistic. It is understood that the first phase of the project has never been rented out. The author visited and found that there are still many vacant rooms on both sides of the unfinished pedestrian street in the second phase, and the existing businesses only entered under the preferential policy of rent-free in the first two years.

The investment reception center and the renovated vacant houses on the pedestrian street are attracting investment (from the author’s field visit and shooting)

Besides, these old shops, which have been recruited again, have not only moved away from the original site, but also transformed from small shops that were traditionally operated into modern mass-produced hotels, and the old flavor no longer exists. In order to expand publicity and increase interests, these cultures have become worthless victims. When talking to a section chief about the present Zhang Baopu, she said:

"Now these things (referring to the newly opened old-fashioned restaurants on the pedestrian street) can’t be eaten, and they are put on this street. In fact, they are well-known, but in fact, the original old taste is wrong. Then what do you mean by old taste? You used to eat it, but now it tastes different. If you haven’t eaten it before, it will be the same if you come for the first time now, won’t it? Nowadays, mass production is definitely different from before, and it will be even worse if tourists are invited to make group meals. However, the original old shop is too broken, and the business philosophy is not good. The benefits are definitely not so good. "

To sum up, the government and developers take the development of commercial tourism as the guide to rebuild historical blocks, and the overall environment of the blocks is destroyed. At the same time, the real historical buildings-the vacant houses after the residents moved are unprotected and repaired, waiting for bulldozers to repeat the old dreams of history in the stormy weather. The coexistence of people and houses can inherit the living historical context, and now the historical block without people and houses has become a dead street. All this, in turn, makes the government’s investment promotion process difficult and bitter.

Here are the 15 diet questions and answers you care about most about losing weight!

  The hot summer is the season for young people to "show off their figure". It is not bad to lose weight in March and April when they have poor appetite and sweat a lot in summer. But when it comes to losing weight, you must also have many questions. Losing weight is always unsuccessful. What is the problem? There are many controversial topics about diet to lose weight. Today, I will pick out 15 most frequently discussed issues to help you reduce this fat clearly.

  1. Can Pu ‘er tea and green tea lose weight?

  If drinking Pu ‘er tea and green tea can reduce weight, it is estimated that Chaoshan area is thin, but it is not.

  Tea contains a lot of tea polyphenols, catechins and some trace elements, which is a very healthy drink and can protect cardiovascular and cerebrovascular diseases. A small amount of caffeine in tea plays a role in improving metabolism. It is really good to drink tea during weight loss, but it is not recommended to buy tea polyphenols products to lose weight in the market.

  2. Can coffee reduce weight?

  If sugar or cream is added to coffee, the calories are not low, and even black coffee without sugar can only temporarily improve metabolism.

  Although coffee can promote weight loss, it contains caffeine, which is not suitable for everyone, especially for people with poor caffeine metabolism.

  3. Can enzymes lose weight?

  Enzymes are actually enzymes, and good quality enzymes have a good effect on regulating intestines, such as constipation. Then why do many people feel that they have lost weight after eating enzymes? Because after the intestines are healthy, more intestinal waste will be excreted. There will be some garbage left in our intestines. If there is more garbage, you will naturally lose a few pounds.

  Moreover, when you drink enzymes, the merchants will ask you to cooperate and eat less food. The total calories are reduced, and the weight loss is normal, just taking advantage of the deficit of total calories.

  4. Can you use food to lose weight?

  Generally speaking, if you lose weight through diet, you will lose weight all over, and you will not lose weight alone. But the body is like a very precise instrument. If you have more fat on your waist, it will tend to lose more fat on your waist.

  However, if you have a need for local shaping, it is still recommended that in addition to diet and the guidance of sports coaches, the effect will be better.

  5. Can you eat spicy food to lose weight?

  In fact, the heat of pepper is not high, and it can also accelerate metabolism. But why do so many friends still ask? That’s because most foods with Chili peppers are accompanied by a lot of oil.

  For example, Sichuan hot pot and Hunan cuisine are typical representatives. Pepper is not the problem, oil is the reason.

  6. What should I do if I lose weight during the physiological period?

  First, don’t eat spicy food, and secondly, don’t eat cold food, such as lemon, watermelon, pear, etc.

  Menstruation needs more nutrients such as protein and iron, which can increase the proportion of red meat and animal blood;

  Eating more miscellaneous grains and increasing the intake of B vitamins will help alleviate emotional problems;

  Dairy products, laver, bean products, kelp and other foods help to increase the intake of nutrients such as calcium and magnesium and relieve dysmenorrhea.

  7. Will losing weight lead to hair loss? What should I do?

  Improper weight loss can really cause hair loss.

  First, iron deficiency can cause hair loss. Check whether you eat less meat because of weight loss, especially red meat rich in iron.

  Second, insufficient intake of protein can also cause hair loss. When protein deficiency is serious, hair will become thin and dry. Increase the intake of meat, eggs and milk beans.

  Third, trace elements such as manganese and zinc are insufficient. Meat and nuts are good sources of trace elements. Insufficient calcium intake, fat metabolism is more than usual during weight loss, and more ketone bodies are produced, which requires calcium ions to balance.

  In order to avoid hair loss, usually eat more dairy products and soy products, and pay extra attention to supplementing vitamins and minerals during weight loss.

  8. Can you recommend some diet food?

  In fact, there is no absolute diet food, and there is no "negative calorie food". For example, cucumber is low in calories, but it is far from enough to consider calories only. It is more difficult to lose weight after malnutrition.

  If you always stare at some "diet food" to eat, it will definitely cause malnutrition in the long run. Hair loss, anemia, delayed menstruation and poor sleep followed.

  9. How to distribute three meals a day is better?

  It is suggested that the ratio of 30% for breakfast, 40% for lunch and 30% for dinner be allocated.

  Eat "good" breakfast. Choose foods that are easy to absorb and digest, rich in protein and less greasy, such as eggs, bean products and dairy products. In addition, it is more perfect to eat appropriate fruits and staple foods, plus a handful of nuts.

  Have a full lunch. The quantity of protein should be matched with vegetables reasonably. Eat less or avoid high-fat food.

  Eat less for dinner. Choose light foods with high dietary fiber content, such as vegetables, soups and porridge. Staple food can be reduced appropriately.

  10. What foods are absolutely inedible?

  Unless you are sick, there is no food that you must not eat. Just because of losing weight, it is not recommended to eat some foods with high calories or too fast sugar rise. The details are as follows: animal skins, fat meat, frying, cakes, bread, drinks, candy, wine, excessive salad dressing, greasy hot pot sauce, thick soup, etc.

  11. Why do you get fat when you drink?

  First of all, among all the nutrients, three productivity nutrients (protein, carbohydrate and fat) can provide energy. Where 1g protein =4kcal, 1g carbohydrate =4kcal and 1g fat =9kcal. However, each gram of ethanol produces 7kcal of heat, second only to fat.

  Secondly, alcohol metabolism needs to pass through the liver, and the metabolism of the liver is slow, so fat is naturally easier to accumulate.

  12. Are there any ways to reduce appetite?

  You can use some tips to reduce your desire for food. For example, drink a glass of water and soup half an hour before meals. When eating, eat foods rich in dietary fiber, such as vegetables, to increase satiety. Chew slowly when eating, use small portions of tableware, and visually "cheat" the brain.

  13. Can I have a midnight snack when I lose weight?

  You can eat it, but the following points should be noted:

  First, choose foods with low fat, low calorie, high nutritional value and easy digestion, such as milk, soybean milk, miscellaneous grains porridge, vegetable soup and fruits.

  Second, avoid indigestible foods, fried, high-fat, sweet, spicy and irritating foods.

  Third, try not to eat for 3 hours before going to bed. It takes at least 2-3 hours for food to empty from the time it enters the stomach. Going to bed after eating, food still stays in the stomach, which not only affects fat loss, but also imposes a burden on the stomach.

  14. Can you lose weight by eating oats?

  Oats can’t lose weight, but why do oats always appear in the list of foods that must be eaten to lose weight?

  That’s because oats are rich in β -Dextran can make us feel full and reduce our food intake. And oats can help delay the rise of blood sugar after meals, make blood sugar more stable and reduce insulin resistance.

  15. What foods should I eat less during weight loss?

  The following types of food are recommended to be eaten less:

  Animal skin. Everyone knows to eat less fat, but animal skins are often easily overlooked. In fact, animal skins contain higher fat content.

  All kinds of sauces. Salad sauce, cream sauce, hot pot seasoning, etc. are high in calories, so it is easy to eat too much while dipping in the sauce.

  Soups. In particular, the broth contains a lot of animal fat, and it is even more inappropriate for uric acid is too high people to drink too much.

  Processing food, beverages, cakes, sweets, etc.; Fried food, hamburgers, French fries, fried chicken, etc.
