Special topic: Wenchuan earthquake in Sichuan

　　　　"Disaster is command and time is life". After Wenchuan County’s "5.12" earthquake with a magnitude of 8.0 on the Richter scale, in the face of this sudden disaster, at the critical moment when people’s lives in the disaster area were seriously threatened, 18 warriors of the first batch of earthquake relief commandos from Aba Prefecture, Sichuan Province, marched on foot for more than 40 hours and more than 200 miles with dauntless heroism in the face of many difficulties such as aftershocks, landslides, harsh environment and difficult conditions.

　　　　Race against time and fight against death, 18 warriors are the first fire rescue team to go to Wenchuan County for disaster relief. They searched and rescued the trapped people for the first time; First time to repair the power plant, so that Wenchuan County resumed power supply for the first time; Send "life-saving water" to 600 million people in the disaster area at the first time; The first time they fought in the most difficult and dangerous frontier … So far, they are still fighting in the front line of earthquake relief …

　　　　Warriors who entered the disaster area walked for more than 40 hours and traveled more than 200 miles.

　　　　At 14: 40 on May 12, after receiving an urgent order from the state government, Aba Prefecture Fire Brigade led 18 officers and men, dispatched 3 rescue vehicles and special equipment led by Ye Guangyuan, political commissar of the detachment, and rushed to the Wenchuan disaster area in the epicenter. The situation along the way was dangerous, with heavy rain, aftershocks, landslides, mudslides, road deformation, and huge stones piling up … making the March extremely difficult. Ye Guangyuan’s political commissar took the lead, and Xin Ping’s chief of staff courageously took the lead, setting an example for the officers and men and taking the initiative to rush to the front of the team. The morale of the officers and men was greatly encouraged, and while clearing the road obstacles, they stubbornly advanced to the disaster area. However, the closer we get to Wenchuan, the more difficult the journey becomes. When the team goes to the Gulgou section of Lixian County (more than 90 kilometers away from Wenchuan County), the vehicles can no longer move forward. Political commissar Ye Guangyuan ordered with the courage and perseverance of a soldier: "Never delay a minute, even if you climb, you must climb to Wenchuan"! It was decided to leave three drivers, namely Xu Guorong, Liu Yang and Ye Chuntao, to stay in the rescue vehicle, and then drive the rescue vehicle to Wenchuan after the road was clear. The remaining 15 officers and men each carried more than 20 kilograms of rescue equipment and walked to the Wenchuan disaster area overnight.

　　　　It was extremely difficult to travel on foot. After 12 kilometers, aftershocks occurred again, and the mountain landslides continued along the way. The sound of flying stones was as horrible as thunder, and the earthquake disaster almost made it impossible. In addition, it was dark at night and the rain was heavy, so the officers and men had to struggle and crawl in the "forbidden area of life".

　　　　Despite the harsh conditions, the officers and men insisted on walking forward, which attracted great attention from china national radio, and conducted a live online interview with Ye Guangyuan, political commissar of the detachment. Political commissar Ye Guangyuan said: Although the rescue road to the disaster area is dangerous, it is the bounden duty and duty of fire officers and soldiers to save the lives of the people in the disaster area. If we arrive one second early, it is possible to save one more person. Even if we go through fire and water, even if we are smashed to pieces, we will make rapid progress!

　　　　Aftershocks are still happening, and stones fall from mountain to mountain, so the officers and men can’t care about their personal safety. Under the leadership of political commissar Ye Guangyuan, the expedition led by chief of staff Xin Ping charged all the way ahead. When traveling 10 kilometers away from Lixian city, people called it the "ghost gate" section, the officers and men ignored the local people’s dissuasion, and the mountain kept falling stones, which might be in danger of death at any time, and resolutely walked forward quickly. After struggling with death, the perseverance and courage of 15 officers and men finally conquered the "death gate" and passed safely.

　　　　The officers and men climbed mountains, crossed rivers and mountains, and arrived in Lixian County on foot for more than 100 hours in a row. Guo Haitao, deputy instructor of Lixian Brigade, neglected the safety of his daughter who went to school in Dujiangyan, the hardest hit area, and his wife who went to work in Wenchuan County, the epicenter, and actively accepted the orders of the superior troops and quickly joined the ranks of commandos.

　　　　Along the way, heavy rain continued, mud was everywhere, mudslides continued, and destroyed vehicles and dead people were seen in many places. The officers and men overcame hunger and fatigue in the extreme state and rushed through dozens of road breaks where boulders and mudslides rolled. The tenacious style of the officers and men and their persistent spirit of caring for the safety of the people in the disaster areas touched the people along the way. Many people sent water, drinks and guidance to lead the way. Sixteen officers and men walked more than 100 miles again despite difficulties and obstacles. At about 14 noon on May 14th, four members, Guo Haitao, Zhou Wenqiang, Li Jinguo and Ma Xiaolong, led by Xin Ping, chief of staff, arrived in Wenchuan County for the first time, and the rest of them arrived safely, winning the first victory of marching on foot and becoming the first fire rescue team to arrive in the disaster area of Wenchuan County.

　　　　More than 40 hours of forced March is a test of perseverance and courage for officers and men. Due to the rugged road shape and fast progress, five or six blood bubbles were formed on the feet of officers and men, and two or three blisters were at least. Some of their faces were scratched by thorns, and some of their feet were cut by stones, but none of the officers and men retreated and were discouraged. Ma Xiaolong, a new soldier, carries more than 20 kilograms of mobile chain saws, and Li Jinguo, a third-phase sergeant, carries heavy rescue equipment and has been charging ahead; Zhou Wenqiang, a third-phase petty officer, took off his clothes and wrapped them in cameras and cameras in heavy rain, regardless of the dangers on the way, and collected touching pictures of officers and men in a sinister environment; Pu Decai, the vice captain of the squadron directly under the company, took the lead in carrying heavy relief equipment and took the initiative to undertake the task of observation and vigilance; With great patience and perseverance, political commissar Ye Guangyuan overcame many difficulties, such as high blood pressure and rapid physical overdraft, and kept the marching speed, and constantly encouraged officers and men in various ways, so that the troops always maintained high morale; With excellent physical quality, tenacious and courageous fighting style, Chief of Staff Xin Ping led the commandos to charge at the forefront of extreme danger. During the March, he left the danger to himself first.

　　　　Fire officers and soldiers came … Fire officers and soldiers came … Many people in Wenchuan County were filled with tears and excited after seeing the fire officers and soldiers, which made the people in the disaster area see hope.

　　　　On the evening of May 15th, three drivers, Xu Guorong, Liu Yang and Ye Chuntao, ignored the danger of flying rocks along the way, and after more than 100 hours of hard travel day and night, they also safely delivered large-scale rescue equipment and rescue vehicles to Wenchuan, providing a guarantee for earthquake relief.

　　　　To repair the power supply, the warriors soaked in muddy water for more than 10 hours.

　　　　After the commandos arrived in Wenchuan, they didn’t have time to rest for a moment. They immediately set up the earthquake relief headquarters of Aba fire brigade with political commissar Ye Guangyuan as the chief commander, and made arrangements for the earthquake relief work. And immediately received the first urgent task of Aba Prefecture Earthquake Relief Headquarters: to repair Xiazhuang Power Plant and restore power supply to important departments in Wenchuan City as soon as possible.

　　　　After the earthquake, the power supply facilities in Wenchuan County were severely damaged, which brought great difficulties to the rescue of the wounded, and the lives of thousands of injured people were dying and in danger …

　　　　Time is life. One minute earlier, it is possible to save one more life. On May 15th, the officers and men of the commando team didn’t have time to rest for a moment, and risked being crushed, crushed and buried by the collapse of rocks at any time. They walked for more than two hours and more than 20 miles and went to Xiazhuang Power Plant for emergency repair.

　　　　After arriving at the power plant, the officers and men found that the 200-meter-long diversion channel of the power plant had accumulated a lot of collapsed stones and sediment, and the mountain might collapse at any time. None of the officers and men retreated. Under the demonstration of Dai Changqing’s deputy detachment and Xin Ping’s chief of staff, the officers and men jumped into the muddy water one by one and cleaned up the blocked gravel and sediment with tools and hands.

　　　　The channel cleaning work is extremely difficult, and it is less than 20 meters per hour. In the battle, some small soldiers can only show their shoulders above the muddy water, but they still insist on fighting. The officers and men didn’t rush to take a sip of water, let alone catch their breath. Some officers and men were injured in many places during the March, and their physical strength was seriously overdrawn, but no one was bitter and tired, and they continued to fight …

　　　　After more than 10 hours of continuous fighting, the stones and sundries accumulated in the water diversion channel have been cleaned up in a large scale, and the 200-meter-long water diversion channel has been excavated with a width of 2 meters. At this time, the hands of Wang Maoneng, Guo Haitao, Pu Decai, Xu Guorong, Deng Baiwei, Tang Wenguang, Wu Wei, Yang Yi, Hu Yong, Ma Xiaolong, Li Jinguo and many other officers and men, headed by Dai Changqing, chief of staff of Xin Ping, have also become bloody. After the water diversion was successful, the first group of generators generated electricity successfully after being tested by the technicians of the power plant.

　　　　The earthquake caused the water diversion channel of the power plant to be damaged to varying degrees, and a large number of sundries were blocked at the intake gate valve, so the water diversion flow of the newly excavated channel could not meet the normal power supply, and the power supply was interrupted instantly. Under the leadership of Xin Ping, the chief of staff, the officers and men of the commandos risked the huge impact of the river to quickly clean up the debris stuck in the intake gate valve. Comrade Pu Decai volunteered to go into the water at the first time. He quickly tied a safety rope and risked his life, and most of his body was immersed in the cold and dirty river water of the river dam. After more than three hours of hard struggle, all the sundries tightly wrapped in the gate valve were cleaned up, and the water diversion flow reached the normal power supply requirements, and the power was successfully sent to Weizhou Town Power Supply Station in Wenchuan County.

　　　　It lasted until late at night, and the officers and men returned to the camp. As soon as they entered the door, the officers and men only drank a few mouthfuls and fell asleep. Hot and hot food, no one to eat, really tired …

　　　　On May 16th, after 105 hours of power interruption in Wenchuan County, the power supply of waterworks, hospitals, government headquarters, public security, fire protection and other important departments was partially restored after emergency repair by commandos and electric technicians. The tenacious fighting style of officers and men was highly praised by Xiao Youcai, deputy commander of the Aba earthquake relief headquarters and deputy governor of the state government. Deputy Secretary Chen Guihua, the executive commander-in-chief of earthquake relief in Aba Prefecture, mentioned the significance of power supply, and used three "too" for the outstanding contribution and role of fire officers and soldiers: "It’s too hard, too effective, and too good for earthquake relief".

　　　　Don’t give up, don’t stop, the warriors are fighting at the forefront of the search and rescue of trapped people.

　　　　At 8 o’clock in the morning on the 18th, Aba Fire Fighting and Earthquake Relief Headquarters received a transfer order. Some people were buried in the earthquake behind Jiexin Garden Credit Cooperative in Wenchuan County. The rescue team has been searching and rescued for 2 days, but it still falls as follows. Zhang Fuchang, commander-in-chief and Xin Ping, deputy commander-in-chief of the earthquake relief headquarters of Aba Fire Force, quickly led the commandos and rushed to the scene for search and rescue with rescue equipment.

　　　　The officers and men found at the scene that there was a 2-storey residential building close to the mountain. The boulder and dust that had been collapsed by the earthquake were almost buried, and the search and rescue channel with a depth of more than 2 meters was dug behind the stairs of the house. Dozens of people on the scene were telling about the situation of the trapped people. According to the family members of the trapped people, the rescue team has been searching and rescuing for two days, and their whereabouts are still unknown. My wife may be buried in the toilet area, and her survival is slim.

　　　　Aftershocks keep happening, rocks fall from mountain to mountain, and time is life. The officers and men can’t care about their personal safety, let alone the danger of falling rocks from mountain, and quickly start search and rescue after readjusting the disaster relief plan. The officers and men used fire-fighting demolition and search and rescue equipment to transfer stones and dust. One hour, two hours and ten hours passed, and no signs of survivors were found in the search and rescue.

　　　　However, the officers and men still did not give up. With the joint efforts of a large number of other search and rescue teams mobilized later, they still did not stop searching, trying to get through the search and rescue channel for the first time and win the final victory of the rescue.

　　　　60,000 victims’ "life-saving water" infiltrated from the hearts of the warriors.

　　　　After the earthquake, the water supply pipe network in Wenchuan county was seriously damaged, and the domestic water and medical water for the affected people and disaster relief teams were all transported by fire forces.

　　　　Water is the source of life. Without it, everything will not survive. Water is the most needed material for human beings. Without it, human beings will also face extinction, which shows how important water is to more than 600 million people in disaster areas.

　　　　Commando officers and men took the initiative to shoulder this arduous task at the first time, transporting and supplying water to the county town and some surrounding towns and villages every day to solve the problem that people, students and disaster relief teams in disaster areas have difficulty in drinking water and using water.

　　　　The officers and men set out at 6 o’clock in the morning and returned to the team at 9 o’clock in the evening, using fire trucks to deliver water and fire hydrants to release water at fixed points. On average, more than 10 fire-fighting vehicles are dispatched every day, and more than 10 fire hydrants are opened at fixed points. The journey is more than 100 kilometers, and the water supply time is as long as 15 hours. The water supply and delivery amount is more than 500 tons, which ensures the domestic water supply of more than 600 million people in the disaster area.

　　　　When they learned that some important places were seriously short of water, the officers and men took the initiative to deliver water to them. After a medical clinic of an Air Force entered the disaster area of Mianchi Town, Wenchuan County on May 16th, due to the distance from the county seat and the large number of people gathered, the water used for medical treatment and domestic use was very tight, and the health of officers and soldiers in the medical clinic and the masses of the wounded could not be guaranteed, which brought a lot of inconvenience to the earthquake relief work. When the officers and men learned about this situation, they immediately dispatched two fire engines every day to deliver water to the officers and men of the medical clinic and the affected people regularly, so as to solve the problem of difficult water use and draught in the medical clinic. Subsequently, water was sent to health departments, medical places, schools, headquarters, disaster relief teams and other related units, which was well received by the disaster relief teams of the people in the disaster areas.

　　　　The scene of water delivery is touching. When the "water of life" flows out from the fire truck, the eyes of the people in the disaster area are moist, and the eyes of the officers and men are moist … The officers and men help the people to carry water, and the people wipe the sweat for the officers and men. The scenes truly interpret "the earthquake is heartless, and the soldiers and civilians are close to each other"!

　　　　By May 28th, the commandos had delivered more than 20,000 tons of water to the people in the disaster area and the disaster relief team.

　　　　Move the position, the warriors are still in the front line.

　　　　With the in-depth development of the earthquake relief work, the sanitation and epidemic prevention decontamination work in the disaster area has become the second battle, which is a top priority and urgent task. According to the unified arrangement of the earthquake relief headquarters of Aba fire brigade, the commando officers and soldiers continue to undertake the work of assisting the local sanitation and epidemic prevention departments to carry out sanitation and epidemic prevention decontamination in the disaster area.

　　　　On May 17, officers and men were ordered to go to the oil company to wash the open space seriously polluted by the corpse parked some time ago. After arriving at the scene, the officers and men ignored the psychological taboo and the residual smell of corpse, and risked being infected by bacteria and acted quickly. During the washing, the sewage wet the trouser legs of the officers and men, and mud splashed on their faces. However, the officers and men put all this behind them, added enough water pressure to wash them with all their strength, and after nearly two hours of hard work, they finally washed the open space with an area of 3 mu.

　　　　In the past few days, according to the requirements of the headquarters, the commandos sent rescue teams every day to wash and clean more than 20 public toilets temporarily used in Wenchuan County, creating a hygienic and clean environment for the people and rescue teams in the disaster areas, effectively curbing the occurrence and spread of epidemic and other infectious diseases in the disaster areas.

　　　　In this earthquake relief, 18 commando officers and men have withstood the test of life and death, resisted the concern for their families, carried forward the dedication of caring for everyone, and always maintained high morale and fighting style to overcome difficulties, and devoted themselves to the front line of earthquake relief. A number of advanced typical figures have emerged, such as Pu Decai, Ma Xiaolong, Deng Baiwei, Li Jinguo and Kuang Jianchong. One person was awarded a second-class merit by the firewire, another was awarded a third-class merit by the firewire, two people joined the the Communist Party of China (CPC), one person was reported to the Central Political and Legal Committee for commendation, and 18 people were all recommended as heroes of earthquake relief by the provincial public security department, becoming a sharp knife team and a team with amazing fighting capacity in the earthquake relief team of Aba Prefecture fire forces.

　　　　At present, these 18 officers and men are still at the forefront of earthquake relief, and continue to write new glories and new chapters in history with indomitable spirit and style!

　　　　Information on the first batch of 18 commandos who went to Wenchuan for earthquake relief.

CCTV News:Recently, the United States has continued to increase its military deployment in the surrounding areas of Iran. The British "Guardian" conducted a rough statistics a few days ago, showing that there are currently more than 50,000 US troops deployed around Iran.

According to the Guardian, the current US military deployment in the Middle East is: 2,500 in Turkey, 5,100 in Iraq, 1,500 in Jordan, 15,000 in Kuwait, 7,000 in Bahrain, 11,000 in Qatar, 2,500 in Saudi Arabia, 5,000 in United Arab Emirates, 4,000 in Djibouti and 200 in Oman, with a total of nearly 54,000. At the same time, the "Lincoln" aircraft carrier battle group and B-52 bombers were also dispatched to the Persian Gulf.

Some analysts believe that the main purpose of the United States at present is to attack the Iranian economy through military deterrence and severe sanctions, incite the dissatisfaction of the Iranian people, and put pressure on the Iranian government. Therefore, the possibility of a war is not great.

Rouhani made a tough voice: resistance is the only choice.

Recently, the situation in the United States and Iraq has suddenly become tense because the United States lifted the sanctions exemption for eight Iranian crude oil importers.

　Rouhani (data map)

According to CNN, the Iranian side believes that the current position of the US government on bilateral relations is "crazy" and "chaotic". On the evening of 19th, US President Trump sent a message on social platforms threatening Iran, saying that if Iran wanted to fight, it would be the official end of Iran. But then the U.S. government changed its attitude, saying that any provocative act by Iran would encounter "powerful forces", but the United States was also willing to negotiate with Iran.

According to Sputnik news agency & radio, citing the Iranian National News Agency, in response to the US remarks, Rouhani stated on the evening of 20th that all Iranian officials had reached a consensus and would stubbornly resist the US sanctions policy.

Rouhani said: "If we quit the Iranian nuclear deal just because of the provocative behavior of the United States, the United Nations and the whole world will impose sanctions on us, except the United States. I support negotiation channels and diplomatic means, but I will not accept it under the current situation. The current situation is not suitable for negotiation. We only have one choice, and that is resistance. "

Ultimate poster

1905 movie network news The annual "5.20" Valentine’s Day is the advertising day of the network fire. Today, the super sweet youth love movie will be shown in advance in 38 cities across the country, offering a sweet date for the audience three days in advance. At the same time, the film released the ultimate poster of "sugar exceeding the standard". The actors were in the world of macaroon-colored candy, and the girl’s heart was bursting with sweetness. Continues the comic book’s Secondary 2 style, and the sweet love atmosphere comes to my face.

Aspect 1: Super youth lineup, there are faces and plays waiting for you to see.

The film Strange Classmate Next Door is directed by Sh Tsukikawa and co-starred by popular Japanese actors Suda Masaki, Tao Tsuchiya, Yuki Furukawa, Yamata Yuki, Ikeda Elaiza and Hamabe Minami. Suda Masaki just won the Japanese Film Academy Award for Best Actor at the beginning of the year, which can be described as the coexistence of strength and face value. As his second film to appear on the big screen in China, and the last time he wore a student uniform, it aroused the crazy expectations of fans. Actress Tao Tsuchiya, who is known as the "Goddess Harvester", is deeply rooted in people’s hearts with her sweet and lovely image. This time, she will "harvest" the goddess soda again, which will form the most "Too Sweet CP" with Suda Masaki in history.

In addition, the audience will also see Suda Masaki and two Japanese powerful actors, Yuki Furukawa and Yamata Yuki, fighting in the same box and enjoying the experience of "hormone bursting" on the big screen. Ikeda Elaiza, who is known as the new Japanese "Otaku Goddess", and Hamabe Minami, the "Flower of Innocence", will also bring wonderful performances in the film.

Aspect 2: adaptation of high-sugar comics, and no discount will be given to protect the sweetness and the Soviet Union.

The film "Strange Classmate Next Door" is adapted from the Japanese super-popular girl cartoon with the same name. After its release, it was voted as one of the most successful full-action movies of the year. In the original, the feelings between Chun and Yong, which are both exciting and cautious, are very touching. As soon as the news of the real change came out, casting became the focus of IP powder. Suda Masaki’s version of Yoshida Haru has been recognized by everyone in terms of appearance and acting skills. Touching the head, knocking on the ground and dating on the roof … … All kinds of shots restored by gods make fans shout "the second dimension wall is broken, this is the spring and Yong in our hearts". Every role is set with distinctive features. Even a chicken named Nagoya is a "showman".

Aspect 3: Refreshing but not greasy, every love line is easy to knock.

Compared with the movies about campus youth, the movie "Strange Classmate Next Door" continues the comic book’s Secondary 2 style, and the plot is funny without losing the throb of love. A number of love lines are in parallel, and the confession is painful and the refusal is crisp and neat. Represented by the protagonists Yoshida Haru and Mizutani Shizuku, kissing is a way to express love, and confession is also a choice between thoughts. Without those so-called entanglements and helplessness, the expression of feelings in Strange Students Next to Me is direct and pure, refreshing and not greasy. The netizens who have seen it say that this film has cured the long-standing "confession phobia". Every emotional line in the film represents a kind of "love values". No matter whether you are in a state of "unrequited love", "lovelorn love" or "lovelorn love", I believe you can get inspiration from the film.

Aspect 4: geek friends guide, the gospel of social fear syndrome

There are also deep thoughts under the sweetness, and the film also discusses the realistic campus interpersonal relationship, which is comparable to a practical "geek" friend-making guide. In the film, Chun and Yong are both "geeks" in the eyes of students. They represent "unsociable" individuals in campus life, but with each other’s help, they learn to accept the goodwill of others and finally integrate into the collective harvest friendship.

School is like a microcosm of society, and everyone needs to establish good interpersonal relationships during their student days. In this process, people who are not sociable may suffer from difficulties in getting along with others. However, after watching the film, you will know that it may be easier to get happiness by facing your own heart and trying to open your heart and accept others.

The movie "The Strange Classmate Next Door" will be shown nationwide on May 23rd.

　　"This time, the liberalization of competition, the decline in new energy electricity prices is an inevitable trend, and it is very likely to promote a new round of industry reshuffle." On June 2nd, when talking about the newly announced wind power and photovoltaic power generation projects will adopt competitive allocation, giving priority to the construction of projects with low subsidy intensity and large slope retreat, Ningxia industry insiders from China’s first new energy comprehensive demonstration zone and the first pilot area of power auxiliary service market in northwest China said so.

　　The New Deal is bound to affect the investment enthusiasm of enterprises.

　　On May 30th, the National Energy Administration issued the Notice on Matters Related to the Construction of Wind Power and Photovoltaic Power Generation Projects in 2019, clarifying that wind power and photovoltaic power generation projects are divided into two categories: those that do not need state subsidies and those that need state subsidies. On the basis of organizing power grid enterprises to demonstrate and implement the conditions for power transmission and consumption of affordable power grid projects, priority will be given to promoting the construction of affordable power grid projects, and then competitive allocation of projects that need state subsidies will be carried out.

　　The relevant person in charge of the new energy department of the bureau said that the purpose of this move is to improve the competitive allocation mechanism of projects requiring state subsidies and reduce the dependence of industry development on state subsidies. The general orientation of wind power and photovoltaic power generation this year is to "adhere to the general tone of striving for stability, accelerate technological progress and reduce subsidy intensity, coordinate project construction and absorptive capacity, and achieve high-quality development".

　　This policy, known as "the most market-oriented policy in history", marks that the national wind power photovoltaic has entered the bidding era.

　　Since the "Thirteenth Five-Year Plan", the application scale of wind power and photovoltaic power generation in China has been continuously expanded, the technical level has been significantly improved, and the cost has gradually decreased. At the same time, however, the subsidy gap continues to widen, and some areas abandon wind, light and electricity.

　　According to the latest figures, the installed capacity of new energy in Ningxia Power Grid is about 15 million kilowatts, accounting for 49% of the generated electricity and 102% of the electricity load, making it the first provincial power grid in China where the output of wind power and photovoltaic power generation exceeds that of the whole regional network. From 2013 to 2018, the average annual growth rate of wind power installed capacity in Ningxia reached 27%, the average annual growth rate of photovoltaic installed capacity reached 40%, the average annual growth rate of new energy installed capacity reached 32%, and the proportion of new energy installed capacity ranked second in the country.

　　An expert from Ningxia New Energy Research Institute, who did not want to be named, analyzed that the fierce competition of energy investment enterprises is mainly reflected in the competition of on-grid electricity price. As soon as the electricity price drops, the return on investment will also decrease, which will inevitably affect the enthusiasm of enterprises to build photovoltaic power plants. On the other hand, it is reflected in some photovoltaic power generation enterprises, which must invest by selling power stations to digest their production capacity, which also has a great impact on their enthusiasm for building power stations.

　　The main reason is that the price of photovoltaic construction has dropped sharply in recent years, and the investment cost has dropped due to the decline in equipment prices.

　　According to the expert, the initial formation price of 20 yuan was the highest per watt, and last year it was reduced to the lowest value, 1.6 yuan per watt. "This also means that the electricity price has reached a low level. The lowest electricity price in Ningxia in the past two years was 0.55 yuan. Now, if competition is liberalized, it is estimated to reach about 0.35 yuan, which is basically close to parity Internet access." He said frankly.

　　Follow the plan and make active adjustments at the same time.

　　Ningxia is rich in wind energy and solar energy resources. Since it was approved by the National Energy Administration in 2012 as the first comprehensive demonstration zone of new energy in China, the solar material and equipment manufacturing industry has entered a stage of rapid development, and a complete industrial chain including silica, industrial silicon, polysilicon, solar cells and components, solar power stations and so on has been built.

　　According to Ningxia 2015 — Planning of Photovoltaic Park in 2020, Ningxia will invest more than 100 billion yuan in photovoltaic industry in five years, and will take the lead in creating a development model of "park-oriented, intensive and large-scale" new energy projects in the country, and build 10 large-scale photovoltaic parks and related supporting industries through centralized planning.

　　"The biggest dilemma faced by photovoltaic power generation enterprises is that the state subsidized electricity fee is not in place, resulting in a shortage of cash flow. The income from electricity sales by enterprises can only be recovered from the benchmark electricity price, and most subsidies cannot be recovered. " The expert revealed.

　　According to reports, up to now, the state-subsidized electricity fee in Ningxia has only been replenished until March 2017, and the two-year state-subsidized electricity fee has not been put in place, resulting in a very tight cash flow of photovoltaic power generation enterprises, and many enterprises have been forced to transfer.

　　In the face of the introduction of the New Deal, Zhang Yongding, a professor at the School of Business of Yinchuan University of Energy, bluntly said that "it is a catfish effect, which will better play the role of the market in allocating resources". Based on his working experience in enterprises and years of teaching research, he said that the state used financial subsidies and other incentives to increase the proportion of renewable energy in the whole energy structure, but the effect was not very good, and some enterprises did not play their due role with subsidies. The introduction of competition mechanism now is to promote the rapid development of the industry.

　　Wang Linling, an associate researcher at the Institute of Comprehensive Economics of Ningxia Academy of Social Sciences, also believes that enterprises should follow the national strategic planning and make corresponding adjustments in time. But at the same time, he hopes to have a step-by-step adjustment process, so that enterprises can gradually adapt. After all, this policy has a certain impact on the investment enthusiasm of enterprises.

　　"Leading photovoltaic power generation to reduce costs, subsidize and achieve parity has risen to the national strategic level. We will take active measures to deal with and cooperate, and hope that the state can help enterprises get out of the predicament and develop healthily, by going up one flight of stairs." The person in charge of a photovoltaic power generation company in Ningxia said that from its own point of view, it is to strive to reduce the cost per kilowatt; To put it further, it is to strive for Ningxia power grid not to limit electricity, otherwise it will cause great trouble to the "breakthrough" road of photovoltaic power generation.

　　In 1897 Kechuang City, Erqi Factory, the former site of the "Erqi" strike in Changxindian, Fengtai District, a special exhibition called "Centennial Follow-up" is going on. Precious exhibits and historical materials, such as the "foreign" railway tracks more than 120 years ago and the payroll of railway workers in Changxindian a hundred years ago, show the vigorous workers’ movement in Changxindian area in the 1920s and the century-long development course of railway construction in China.

　　Eight modern buildings remain in the former site of the "February 27" strike.

　　Walking into the 1897 Kechuang City of Erqi Factory, there are several European-style buildings scattered around the central lawn. The unique triangular mountain flowers and round ventilation window on the gable are unique. These old buildings with a hundred years of history are the modern architectural remains of Erqi Locomotive Factory.

　　The history of Erqi Locomotive Works can be traced back to 1897. As a part of Lubao Railway, the Qing government set up a simple small factory on the north side of the west bank of Lugou Bridge that year-Lugou Bridge Machinery Factory of Lubao Railway. In 1900, under the coercion of western forces, the northern end of Lubao Railway was extended to Qianmen and renamed Jinghan Railway. The original Lugouqiao Machine Factory of Lubao Railway was moved to Changxindian and renamed as "Changxindian Machine Factory of Jinghan Railway". The earliest batch of industrial workers in Beijing was born here, which is one of the birthplaces of modern industry in Beijing, and it has become the starting point and model of combining Marxism with the workers’ movement in China in the changing historical process. Mao Zedong once commented, "The China Workers’ Movement started from Changxindian Railway Factory."

　　In 1966, the factory was renamed as "Beijing Erqi Locomotive and Rolling Stock Factory", which was named after "Erqi" for the first time. Since then, Erqi Factory has continued to operate until it stopped production and transformed in 2018.

　　Today, there are still 8 modern architectural remains in Erqi Factory, including 7 office buildings and 1 production workshop. Among the office buildings, 6 are French style buildings and 1 is Belgian style buildings. As a whole, the building is built with fair-faced brick walls, with two slopes covered with iron tile roofs, modern doors and windows decorated, triangular mountain flowers on the upper part of gables, decorative lines around the feet, and a circular ventilation window in the center. The production workshop is a typical modern workshop building form.

　　These eight modern architectural remains of Erqi Locomotive Works were selected as the seventh batch of "National Key Cultural Relics Protection Units" in 2013, which is one of the former sites of the "Erqi" strike in Changxindian, Fengtai District. After the dismantling of the manufacturing industry of Erqi Locomotive Company in 2018, these modern architectural remains are in an idle state. At present, Fengtai District Cultural and Tourism Bureau has organized and started the structural inspection of cultural relics buildings, and the repair work will be carried out later.

　　Precious historical materials reproduce the railway workers’ movement a hundred years ago

　　In the auditorium of the factory, which was built in 1933, the special exhibition "One Hundred Years of Follow-up" is under way. Entering the special exhibition hall, a train "drives" head-on. This is a set based on the first generation locomotive of "Mao Zedong". The hammer and caliper on the front of the locomotive are the symbols of workers. The ground under the locomotive is covered with glass plates, and there are two rails under the glass plates. These two railway tracks have a lot of origins: one was made in 1896 and the other was made in 1897, when they crossed the ocean to Beijing and were used to build the Lubao Railway.

　　There is a historical photo of Zhang Zhengui in the exhibition, which is the image of Changxindian Railway Station when it was completed in 1899. Mao Zedong, Deng Zhongxia and other revolutionary movements in Changxindian all got off here.

　　In the exhibition, there is also the wage table of Changxindian Locomotive Works at that time, that is, the "salary" list. At that time, the factory was very strict with the management of workers, and implemented a "big week" working system, that is, one day off every two weeks, going to work at 6 am and leaving work at 6 pm every day, excluding lunch breaks. Ordinary workers had to work 11 hours a day, but their wages were only a few cents, and it was difficult for these ordinary workers to get all their wages. However, foreign factory directors and employees work 8 hours a day and take a day off every week, but their wages are several times, dozens of times or even higher than those of workers.

　　At that time, apart from the double oppression and exploitation of imperialism and warlords, the foremen also set up many unreasonable regulations privately, such as fines for drinking water and speaking during working hours, and the foremen used the money exploited by the workers to build houses for the workers to live in collectively, and forced the workers to join in for dinner, which was called "Guo Gang". There are twenty or thirty people to fifty or sixty people in each "pot gang", and at most 70 people live in three rooms. After layers of exploitation, workers get very little salary.

　　Before and after the May 4th Movement, in order to find the knowledge and truth of saving the country and strengthening the country, a large number of aspiring young people went to France to work and study. Why did the preparatory class for studying in France choose to be established in Changxindian? It turns out that Changxindian Railway Factory was built and managed in the French, which has the foundation of learning French and can also provide opportunities for work-study.

　　After the May 4th Movement, railway workers in Changxindian began to accept the influence of new ideas. In March, 1920, Li Dazhao, Deng Zhongxia and others secretly established the Marxist Theory Research Association in Peking University. Shi Wenbin and Ge Shugui, railway workers in Changxindian, were members of the Marxist Theory Research Association. In order to publicize Marxism to workers and awaken their class consciousness, the communist party early organization in Beijing put forward the slogan of "Go among the workers". After the establishment of the Beijing communist party Group at the end of 1920, Li Dazhao sent Deng Zhongxia and others to Changxindian to consult with Shi Wenbin and other workers to organize a labor cram school. Changxindian labor tutorial school is known as the rising place of "Red Star in the North" and has trained a group of backbones for the workers’ movement. In the second half of 1921, Shi Wenbin, Wang Jun and Kang Jingxing joined the Party and became the first batch of workers in Changxindian, party member.

　　The old factory area, which has witnessed the vigorous workers’ movement for a hundred years, has been transformed into a science and technology city with a new format. Under the leadership of the Communist Party of China, China’s railway industry has also developed vigorously, and its independent innovation ability has been continuously enhanced, and it has made one remarkable achievement after another.

　　Transformation of Erqi Old Factory Building Embracing New Business Form

　　The history of Erqi Factory has continued from modern times to this day. The present 1897 Kechuang City of Erqi Factory was transformed from a century-old factory. Walking in the factory, I saw the boring machine turned into a waterfall fountain, the waste industrial iron drum turned into a black-and-white cow, the small crane became a road flag, and the shovel head and valve were painted with different colors to become tropical fish and bouquets.

　　In addition to these amazing landscapes under the arrangement of waste instruments and tools, the whole factory has bid farewell to the old appearance of industrial production and become a brand-new urban living space.

　　Here, we can see a new space with industrial style and fashionable style inside, and Building N16 is one of the representative works. It used to be a factory building with an area of more than 600 square meters and a height of 10 meters. After careful design, it was transformed into a three-story space with a usable area of more than 1,200 square meters. It has a large-scale ladder "classroom" that can accommodate more than 120 people at the same time, a shared reading area, and a multi-functional conference room, office and living room that can accommodate 30 to 100 people.

　　Factory buildings have been transformed into incubators, cultural and creative spaces, restaurants and bars, children’s entertainment spaces and shopping spaces, enriching people’s lives in Changxindian and even the west bank of Fengtai section of Yongding River. The 1897 Science and Technology Innovation City of Erqi Factory has injected a strong vitality into Changxindian and led a new way of regional development. (Sun Ying)

1905 movie network news　On September 8th, the film "The Big Leftover Marries" held a signing ceremony for the heroine in Beijing, and it was announced that Ada would join the film as the heroine. It is understood that Ada will play a bass player in the film, and he will be specially slimmed down to conform to the role image. Ada said that he can’t avoid the problem of age. Now, if he wants to be close to the role, he must first slim down.

Director Zorro said that when she was writing the script for this film, she hoped that the older girl who played rock could fly against the wind. He introduced that he wrote a story about a girl who failed in life: "I think when I write a script every day, whether I want to find a sad actor or a beautiful actor, but I always have a sunny role in my mind. Finally, I chose Ada. "

Ada revealed that he knew director Zorro more than ten years ago. At that time, she was the host of the music festival, and Guo Guide was a musician. Zorro had hoped to cooperate with Ada in music, but it was not until now that she became attached to movies. Ada said that he was very moved after reading the script, because although the film was a comedy, it was warm and lively. Zorro also hopes that Ada can use laughter to interpret the sad side of the characters in the film.

When talking about the identification with the heroine, Ada said that she can speak for the failed life because she is willing to pay the price for all her decisions: "But I don’t think I have a failed life because I have the endurance to make any decision." She also revealed that in order to play the bass player well, she also learned from her friend Dapeng. In the movie, there will also be a little egg why Ada didn’t join the sewing machine band.

According to reports, the movie "The Big Leftover Wedding" will start at the end of September 2020 and is scheduled to be officially released on November 11, 2021.

　　Efficacy and function of green teaDrinking green tea often has many benefits. According to the latest report of British "Reuters News Network", a large-scale new Japanese study published in American Journal of Clinical Nutrition found that the elderly who often drink green tea are more flexible and independent than other elderly people. The effects and functions of green tea are as follows:

　　1. Sun protection

　　Recently, a study in the United States pointed out that catechins in green tea have a strong antioxidant function. After skin care products containing green tea are applied to the skin, even if they are exposed to the hot sun, the peroxides that cause sunburn, relaxation and roughness of the skin can be reduced by about 1/3. This proves that the ingredients in green tea have sunscreen function.

　　2. Radiation protection

　　For the busy people, the easiest way to resist computer radiation is to drink 2 ~ 3 cups of green tea and eat an orange every morning. Because tea is rich in provitamin A, it can be quickly converted into vitamin A after being absorbed by the human body. Vitamin a can synthesize rhodopsin, which can makeeyeYou can see things better in dim light. Therefore, green tea can not only eliminate computer radiation, but also protect and improve eyesight.

　　3. Reduce blood fat

　　Drinking tea can reduce blood lipids and cholesterol, and make the body lighter. This is because of the comprehensive coordination of phenolic derivatives, aromatic substances, amino acids and vitamins in tea, especially the comprehensive effect of tea polyphenols, theanine and vitamin C, which can promote fat oxidation, help digestion, reduce fat and lose weight.

　　4. Anti-halitosis

　　Green tea contains fluorine, in which catechin can inhibit the action of cariogenic bacteria and reduce the occurrence of dental plaque and periodontitis. Tannic acid contained in tea has bactericidal effect, which can prevent food scraps from breeding bacteria, so it can effectively prevent bad breath.

　　5. Anti-aging

　　Antioxidants contained in green tea help to resist aging. Because of the process of human metabolism, if it is over-oxidized, it will produce a lot of free radicals, which will easily age and cause cell injury. SOD (Superoxide Dismutation) is a free radical scavenger, which can effectively remove excess free radicals and prevent the damage of free radicals to human body. Catechins in green tea can significantly improve SOD activity and scavenge free radicals.

　　6, antibacterial

　　Studies have shown that catechins in green tea can inhibit some bacteria that cause human diseases, and at the same time, it will not harm the proliferation of beneficial bacteria in the intestine, so green tea has the function of whole intestine. Studies have shown that tea polyphenols can eliminate excessive harmful free radicals in the body, and can regenerate efficient antioxidant substances such as α-VE, VC, GSH and SOD in the human body, thus protecting and repairing the antioxidant system, which has significant effects on enhancing the body’s immunity, preventing cancer and preventing aging.

　　7, prevent stomach trouble

　　A study shows that drinking more green tea can prevent chronic gastritis and gastric cancer. The study found that the longer people drink green tea, the lower the rate of chronic gastritis and gastric cancer, and the rate of gastric cancer of people who love green tea is 48% lower than that of people who don’t like tea.

　　8. Cancer prevention

　　Green tea can inhibit some cancers, but its principle is limited to the inference stage. Drinking more tea is bound to have a positive encouraging effect on preventing the occurrence of cancer.

　　9. Promote digestion

　　Recent research reports show that green tea can help improve indigestion, such as acute diarrhea caused by bacteria, and drinking a little green tea can alleviate the condition.

　　Experts specially remind: the fresher the tea, the better. Nutritionally speaking, the nutrients of the freshest tea are not necessarily the best, because the so-called new tea refers to the tea that has been picked for less than a month. Because these tea leaves have not been placed for a period of time, some substances that have adverse effects on the body, such as polyphenols, alcohols and aldehydes, have not been completely oxidized. If you drink new tea for a long time, you may have uncomfortable reactions such as diarrhea and abdominal distension.
