At 9: 00 on June 23, with the Xiaolangdi Reservoir discharging at a flow rate of 2,600 cubic meters per second, it marked the official start of the Yellow River water and sediment regulation in 2025.

　　On July 1st, the Yellow River will officially enter the main flood season. According to the regulations, the water level of the relevant reservoirs should be reduced to the flood limit level to make room for flood control. According to the principle of safety, controllability and overall consideration, combined with the requirements of drought resistance in the lower reaches of the Yellow River and flood prevention in the middle reaches of the Yellow River, and firmly grasping the "bull’s nose" of regulating the relationship between water and sediment, the Yellow River Water Resources Commission decided to start the implementation of water and sediment regulation in the Yellow River in 2025 by jointly dispatching Wanjiazhai, Sanmenxia and Xiaolangdi reservoirs from June 23, so as to scientifically regulate the relationship between water and sediment.

　　According to the inflow of water from the middle reaches of the Yellow River and the water storage situation of the reservoir, in order to enhance the follow-up power of water and sediment regulation in Xiaolangdi Reservoir, give full play to the water storage benefits above the limited water level of the reservoir in flood season, and minimize the impact on aquatic organisms and their habitats, this water and sediment regulation will last for about 17 days in combination with years of practical experience in water and sediment regulation, and comprehensively consider the objectives of drought resistance, irrigation and supply protection, reservoir dredging for flood season, river siltation reduction, and estuary ecological water replenishment. During the period, the joint dispatching mode of Wanjiazhai, Sanmenxia and Xiaolangdi reservoirs, with cameras of Luhun, Guxian and Hekoucun reservoirs as the tributaries, was adopted, and the maximum discharge of Xiaolangdi Reservoir was controlled at Huayuankou Hydrological Station of about 4,600 cubic meters per second. Considering the sediment discharge and siltation reduction of the reservoir and the aquatic organisms and their habitat ecology in the downstream river, the peak sediment concentration at Huayuankou Hydrological Station should be controlled not to exceed 359 kg/m3.

　　Since the beginning of this year, faced with the grim situation of drought in many provinces (regions) in the Yellow River Basin, the Yellow River Committee has thoroughly implemented the spirit of the important instructions of the Supreme Leader General Secretary on flood control and drought relief, conscientiously implemented the work deployment of the Ministry of Water Resources, made drought relief and irrigation and supply the first priority, paid close attention to the development of drought in the basin, scientifically dispatched key reservoirs in the basin, and accurately matched the domestic water demand of urban and rural areas in the basin with the irrigation demand of irrigation areas. It has launched emergency response five times, with a total water supply of 13.5 billion cubic meters, providing a strong water resource guarantee for ensuring water supply security and food security

　　Regulating water and sediment in the Yellow River is one of the important means to adjust the relationship between water and sediment in the Yellow River. Since 2002, on the basis of a lot of scientific research and experiments, the Yellow River Committee has seized the possible opportunity to continuously carry out water and sediment regulation in the Yellow River. The Yellow River water and sediment regulation will strive to achieve a win-win goal: to meet the needs of downstream irrigation and supply, and to ensure the safety of drought-resistant water use in the later period; Maintain the middle water channel in the lower reaches of the Yellow River; Realize the sediment discharge and siltation reduction of the reservoir, optimize the siltation form of the reservoir, and minimize the impact on aquatic organisms and their habitats; Implementing ecological regulation of the Yellow River and ecological water replenishment in the delta; Further explore the law of sediment transport in reservoirs, downstream rivers and estuaries.

　　The Yellow River water and sediment transfer has a large flow and a long duration. The Yellow River Committee attached great importance to it, strengthened organization and leadership, scientifically formulated plans, and made arrangements in advance. On June 15th, it sent advance notices to the management units of Shanxi, Shaanxi, Henan and Shandong provinces, the River Affairs Bureau, the Sanmenxia reservoir area, and the relevant reservoirs and power grid management units to inform the relevant situation, and to the organization and leadership, hydrological monitoring and forecasting, reservoir operation, risk investigation and emergency rescue, and wading safety.

　　During the Yellow River water and sediment transfer period, the Yellow River Committee will pay close attention to the weather situation changes, timely analyze the water and rain conditions, strengthen emergency duty and flood control consultation, strengthen real-time reservoir dispatching, strengthen project inspection and defense, ensure the smooth progress of water and sediment transfer, and ensure the safety of personnel and projects.

At 9: 22 on 25th, lawyer Li Chunguang published the latest progress of the case in his Weibo. From the bulletin, the reporter learned that the Tsinghua University school has read the previously issued "Lawyer’s Letter", and the school’s top management began to contact Zhu Ling’s parents. The lawyers’ group has also started to apply to the the State Council Legislative Affairs Office for information disclosure. At present, the Beijing police are still in communication with Zhu’s parents.

The reporter contacted Li Chunguang by telephone. He said that Zhu Lingan’s progress is quite slow. "This process is also difficult, so the progress of the case was released today, and thanks to the cooperation of other members of the lawyers’ group." According to Li Chunguang, they set up a special lawyer group for Zhu Lingan, with a total of 10 people. "Based on the requirements of the school and respecting the wishes of Zhu’s parents, lawyers will not intervene in the contact process for the time being, nor will they accept any interviews." Li Chunguang said.

19 years ago, Zhu Ling, a talented and beautiful female college student in Tsinghua, was strangely poisoned, and the case has not yet been solved. However, the talented woman in the past is now severely paralyzed and completely demented, and she can’t take care of herself.

In August this year, Li Chunguang of Yunnan Lingyun Law Firm, as the representative lawyer of Zhu Ling, sent a "Lawyer’s Letter" to Tsinghua University, officially starting the accountability procedure for the school. At present, the school has read the Lawyer’s Letter, and the senior management of the school has started to contact Zhu Ling’s parents.

Over the years, many doubtful points in Zhu Ling’s case have not been completely uncovered. The police have determined that the case was poisoned, but who did it? Why did the case finally go away? Zhu Ling’s college roommate Sun Mou, as the only suspect in the thallium poisoning case in Zhu Ling, issued a statement claiming innocence in 2005, which made the case even more confusing.

Zhu Ling’s father, Wu Chengzhi, said in an interview that Sun Wei was the only suspect.

Review of thallium poisoning cases in Zhu Ling

On November 24, 1994, Zhu Ling became ill for unknown reasons, with pain in limbs, and the cause could not be diagnosed. Later, her condition improved and she was discharged. On March 9, 1995, Zhu Ling became ill again for unknown reasons and went to Peking Union Medical College Hospital for medical treatment. On March 15th, Zhu Ling’s symptoms became worse, and facial muscle paralysis, eye muscle paralysis and spontaneous breathing disappeared.

On April 10th, 1995, Bei Zhicheng, a senior high school classmate in Zhu Ling and a student of mechanics department in Peking University, translated the illness into English and sent an e-mail for help through the Internet. Most of the replies thought that Zhu Ling was poisoned by thallium. However, Union Medical College Hospital can’t do relevant tests. On April 20th, Zhu Ling’s parents found Professor Zhenyang Chen who could do thallium poisoning test, and the latter issued a test report, thinking that Zhu Ling was poisoned by thallium twice, and determined that someone had poisoned him, and suggested taking Prussian blue for detoxification. At this time, however, Zhu Ling’s nervous system has been seriously damaged.

On the evening of April 28th, 1995, Zhu Ling’s parents reported the case to the Security Section of Tsinghua University. However, the Security Section immediately notified Zhu Ling’s roommate and asked them to protect the evidence. From April 28th to May 7th, there was a theft in Zhu Ling dormitory, and Zhu Ling’s toiletries were lost. Since then, no progress has been made in Zhu Lingan.

On April 2, 1997, the police suddenly summoned Sun, and after eight hours of questioning, Sun was taken home by his family. Since then, the police have never looked for Sun.

On December 30, 2005, Sun made a statement on the Internet claiming innocence, and some students replied with their real names or pseudonyms.

On January 29, 2006, a person who claimed to be a classmate of Sun’s published an article anonymously on the Internet, disclosing the "posting outline" that Sun sent to his friends before making a statement on the Internet, instructing how to cooperate with the reply.

On May 3rd, 2013, a petition about Zhu Lingan appeared on the website of the White House, with more than 100,000 signatures. Zhu Lingan once again entered the public eye. On the afternoon of the 7th, Zhu Ling’s father, Wu Chengzhi, was interviewed by Phoenix.com at home, saying that he disapproved of the White House petition and suspected that Sun Wei was the only suspect.

On May 8, 2013, the Beijing Public Security Bureau said in a statement in Weibo that "we deeply regret that this case has not been solved" and expressed "deep understanding and sympathy" for Zhu Lingling’s personal misfortune. The Beijing Municipal Public Security Bureau said that there was no interference in the work. "Some cases are limited by the investigation conditions, and due to objective factors such as the loss of evidence, they cannot be detected in the end." Beijing police hope that the public can treat it rationally and respect the law of investigation.

Zhu Lingjia’s current situation

Status quo in Zhu Ling: Life can’t be taken care of by parents.

On November 24th, 1973, Zhu Ling was born into an intellectual family in Beijing, and she had a sister Wu Jin (a biology student in Peking University who died unexpectedly during a spring outing in Yesanpo in 1989). Zhu Ling studied piano since he was a child, and began to study guqin at the age of 15. In 1992, she was admitted to the Chemistry Department of Tsinghua University. She is versatile, not only the main member of Tsinghua University Folk Band, but also the second-class swimmer in Beijing.

Stepping into Zhu Ling’s home will make people feel that time and space have stagnated for 20 years, with simple furnishings and mottled walls. In the dim light, everything seems to stay in the 1990s. Now 39 years old, she lives entirely by her parents. The old man spends most of his time taking care of Zhu Ling and tracing the real murderer.

When it comes to her daughter’s daily life, Wu Chengzhi is rarely active: "We get up every day when we wake up and help her up. The first thing is to clean her trachea: atomize, clear phlegm, wash her lungs, then inject insulin, and then feed her breakfast spoonfuls." Rehabilitation exercise is also a compulsory course for Zhu Ling every day. Kneeling and crouching can’t be done by herself, so her parents, who are 70 years old, help together. My father stands in front, holding her knees with her daughter in a wheelchair, while her mother Zhu Mingxin holds her daughter’s waist tightly behind to prevent her from being injured. Zhu Ling’s father sighed: "I can’t do it without exercise. My calf was as thin as a stick when I was hospitalized the year before last."

Zhu Ling is hospitalized almost every year, ranging from half a month to half a year. A cold in 2011 made her stay in the intensive care unit for 10 months, costing more than 600,000 yuan. "It’s okay not to get sick, but it will cost more when she gets sick." The cold caused a lung infection and she used a ventilator, so that she can only eat liquid food so far.

In 2004, Zhu Mingxin fell down at home, three cranial and cerebral vessels were broken, and a titanium alloy was repaired by knocking on his skull. Speaking of this matter, Wu Chengzhi felt very lucky: "The doctors in the hospital are very familiar with the order. When I saw her mother, the chief doctor came from home immediately. We haven’t paid the money yet, and the doctor is already doing craniotomy, otherwise the consequences will be unimaginable. This is really a blessing! "

The optimism and firmness of the two old people are moving. In their eyes, "I can do 60 knees and squat" and "I can do better kicking today" … … Every progress of my daughter is extremely precious.

Under the care of his parents, Zhu Ling lived these years safely. But when it comes to the future, the two old people still have worries: "We are now paying attention to our diet and hope to live as long as possible. What should Zhu Ling do if we are gone?"

　　Garbage is called "misplaced resources". How to put these resources back in place? The experience of various countries shows that sorting garbage from the source can help to recycle resources to the maximum extent, solve the "besieged city" of garbage and promote sustainable development.

　　America: Classification brings transformation.

　　When it comes to new york, it is difficult to associate this attractive international metropolis with a garbage city with sewage and stinking air. In fact, before the end of 19th century, new york was one of the dirtiest cities in the world. At that time, the streets of new york were littered with garbage, mosquitoes and flies danced wildly, and the foul smell made many residents never dare to open the window. Poor sanitary conditions became a hotbed of various diseases.

　　It was not until the appearance of health engineer George Welling that new york saw hope. In 1895, as the street sanitation commander, Wei Lin established the first garbage recycling and sorting system in new york history, put forward a series of regulations and specific measures for producing soap and agricultural fertilizer from food waste, and called on the whole people to pick up brooms to clean the streets.

　　Thanks to the joint efforts of the whole people, new york has gradually got rid of the dirty environment and established a more systematic and perfect method of garbage sorting and recycling. According to the latest law in 1989, new york residents must sort their garbage before they throw it away. Recyclable garbage is divided into two categories, paper and cardboard are one category, and metal, glass and plastic products are another category, which must be put into garbage bins of different colors respectively.

　　In recent years, new york has been exploring more detailed waste sorting methods, trying to recycle food waste separately and use it for biogas power generation and composting. The local government believes that increasing garbage recycling will not only help to purify the environment, but also save a lot of government expenses.

　　Japan: Close to the Extreme Classification

　　As a densely populated city, Tokyo, Japan, was once plagued by garbage siege and environmental pollution. At the end of 1970, the Japanese parliament completely revised the Cleaning Law and enacted the Waste Disposal Law to curb waste discharge and properly classify, keep, collect, transport, regenerate and dispose of waste.

　　With the long-term efforts of all walks of life, the urban environment in Tokyo has been greatly improved, and the garbage classification has become more detailed and complicated. Combustible garbage, noncombustible garbage, kitchen waste, metal garbage and plastic garbage … … The fine classification makes it not so simple to throw garbage.

　　For example, a cigarette box needs to be discarded in three categories: the plastic film wrapped outside is plastic garbage, the box is combustible garbage, and the aluminum foil at the seal is metal garbage.

　　Many garbage collection points can be seen in the streets and residential areas of Tokyo. These collection points are all posted with delivery instructions, which introduce the classification method and collection time of garbage in the form of pictures and texts, such as when to discard what garbage seven days a week. If you miss the specified time, you can only wait until the next collection day to lose it. If you want to throw away large pieces of garbage such as bicycles and wardrobes, you need to apply by phone in advance and buy treatment vouchers. The price of each piece ranges from several hundred yen to thousands of yen. If you throw away garbage at random, you will be fined or even imprisoned.

　　Germany: the details are constantly optimized

　　In Germany, domestic waste is roughly divided into non-recyclable waste, packaging waste, paper waste, biological waste, electronic waste, glass waste and so on, and their destination is trash cans with different colors.

　　Germany also promotes the recycling of beverage bottles by setting a deposit. For example, a 1.5-liter bottle of ordinary mineral water costs 0.19 euros, but an additional deposit of 0.25 euros is required for plastic bottles filled with water. You can only get the deposit back after the bottle is returned by the bottle collector in the supermarket.

　　With the participation of families, schools and other sectors of society, German children learn the method of garbage classification from an early age and take it as a natural thing. The waste treatment plant will also let people know more about waste sorting and its importance by organizing visits.

　　Garbage sorting and recycling has also spawned new business models, such as garbage management companies. Different kinds of garbage have different disposal fees. If recyclable garbage such as plastic packaging and paper products is put into a bucket of non-recyclable garbage, higher disposal fees will be paid. Garbage management companies can help people reduce the cost of garbage disposal as much as possible.

　　For example, entrusted by the community manager, the staff of the garbage management company will go to the community every three to five times to reclassify some misclassified garbage, and provide regular consultation activities to popularize the knowledge of garbage recycling to residents and help people classify garbage more accurately. Although residents have to pay part of the expenses of the management company, with the sharp reduction of garbage disposal fees, residents have not only saved money, but also contributed to environmental protection.
