The news that Wu Jihong, a girl from Renmin University of China, could not find a suitable job after graduation, and ended up living in the mountainous area of ??northern Jiangxi, becoming the mother of six children in an extremely poor family, has become a hot topic in society. Reporters recently learned that there is also a prestigious school student in Taizhou who is in a similar situation to Wu Jihong.

He was admitted to Harbin Institute of Technology (hereinafter referred to as Harbin Institute of Technology) at the age of 16. Starting from his junior year, he relaxed his professional studies due to his obsession with mathematics, and ultimately failed to obtain a diploma. After returning home, he continued to indulge in his "mathematical research" for more than 20 years. In the end, he chose to give up. He has no skills and cannot do physical work. Today, he only relies on the government's monthly subsistence allowance of 400 yuan to survive.

He is Liu Hanqing from Class 8095 of Harbin Institute of Technology. He currently lives in a three-room farmhouse with a exposed roof in Shuangmu Village, Dainan Town, Xinghua, Taizhou. After the Dragon Boat Festival holiday, the reporter approached Liu Hanqing to explore the tragic story of a "genius boy" who became a "low-income household".

Liu Hanqing lives in this dilapidated house.

He is living a destitute life in front of him

“400 yuan a month is enough”

One morning after the Dragon Boat Festival holiday, the reporter and his party walked along the Ningjingyan Expressway Exit the "South" exit and go east for about 4 kilometers to Shuangmu Village, where Liu Hanqing is located.

Since Liu Hanqing did not have a mobile phone and did not know where his home was, the reporter and his party asked the Shuangmu Village Department for help. Song Yinfeng, the enthusiastic village accountant, willingly acted as a guide and led us there. After walking through several narrow and wide alleys, Song Yinfeng stopped in front of a courtyard door, "This is Liu Hanqing's home."

It is better to say that it is a courtyard door than two piles of bricks. There is an aisle left in the middle, with a piece of wood standing on each side of the aisle, and another piece of wood across the top, which becomes the "door". Walking into the courtyard door, the reporter saw an old-style three-room tile-roofed house. The age of this house can be seen from the broken plastic film on the east wing window. The door of the main room was wide open. Shoes, shabby clothes, various bottles and cans...it was filled with debris, making it impossible to stand. There is light in several places on the roof of the east wing.

"Liu Hanqing! Liu Hanqing!" Song Yinfeng shouted for a long time, but no one was found. After waiting for more than ten minutes, Song Yinfeng, unwilling to give up, went into the house again to search. This time, he found Liu Hanqing sleeping on the bed in the east wing.

The reporter saw Liu Hanqing with fair skin, a big forehead, and a pair of myopic glasses on the bridge of his nose. Liu Hanqing said that he currently lives alone in this house. His parents are old and live in his brother's house. In the kitchen, the reporter saw two iron pots, one with a rice dumpling and an egg, and the other with a little porridge. Liu Hanqing said that this was left by his mother for him. "I eat whatever she cooks. I don't eat much."

Liu Hanqing has no job and cannot do farm work. He has never been married and has no children. He needs to eat Valium every day to sleep. A few years ago, the government provided him with a minimum living allowance, and he received a monthly living allowance of 400 yuan. "Can I support myself with a living allowance of 400 yuan a month?" "I can't spend much money, 400 yuan a month is enough." Liu Hanqing's answer was beyond the reporter's expectations.

He used to be high-spirited

When he entered Harbin Institute of Technology at the age of 16, an article made him obsessed with mathematics

In 1980, 16-year-old Liu Hanqing scored 398.5 points with excellent results With good grades, he was admitted to the heat treatment major of the Department of Building Materials of Harbin Institute of Technology. In the eyes of many people at the time, he was a "genius" as a young man, extremely smart. After entering Harbin Institute of Technology to study, his future was limitless. The reporter learned that Harbin Institute of Technology is affiliated to the Ministry of Industry and Information Technology and is one of the first universities to enter the national "211 Project" and "985 Project". Many top talents in my country's aerospace field come from Harbin Institute of Technology.

In his first two years of college, Liu Hanqing had excellent grades and was well received by his teachers. The reason why Liu Hanqing became obsessed with mathematics was that he was influenced by Xu Chi's reportage work "Goldbach's Conjecture". "Goldbach's Conjecture" was published in 1979 and caused a sensation across the country. At that time, Liu Hanqing was preparing for the college entrance examination and did not pay too much attention to it. It wasn't until one day in his junior year that he accidentally read this article in the school library. By this time, the "Chen Jingrun craze" in the whole society had subsided. Perhaps it was an arrangement in the dark, but fate opened "another door" to him. He was gifted in mathematics. Because of this article, he plunged into the ocean of "number theory" and determined his own research direction: The distribution of prime numbers among natural numbers. The more Liu Hanqing chewed it, the more mysterious and interesting it became, and he determined to "do better than Chen Jingrun."

Liu Hanqing was obsessed with "the study of mathematics". He recalled that when he was at his craziest, he reached the point where he forgot about food and sleep. Even eating felt like a waste of time and he only slept for two hours a day. Correspondingly, he became less and less interested in heat treatment and was only obsessed with his "mathematical world." After the department head and counselor found out, they talked to him and asked him to focus on studying his major. If you really want to study mathematics, you must first get a diploma. But he couldn't listen to what the teachers said. By my senior year, I was unable to graduate because I failed many subjects. Being unable to obtain a diploma because of his "love of learning" was rare at Harbin Institute of Technology and even among universities across the country.

Harbin Institute of Technology gave him one year from the perspective of caring for students. However, this year, Liu Hanqing was still studying his "number theory". "At that time, it was like being possessed by an evil spirit." Liu Hanqing said.

Without getting a diploma, Liu Hanqing would not be able to enjoy the state's "job-assignment guarantee" treatment. Many of his classmates were assigned to the Ministry of Aerospace Industry or its affiliated companies.

In 1985, Liu Hanqing, a farmer’s father, used the same pole he had used to carry his son’s luggage back to college to pick up his son’s luggage from Harbin.

Crazy "chasing numbers" for more than 20 years

No one recognizes mental anxiety

Liu Hanqing's family was greatly disappointed when he returned to his hometown. The neighbors thought he was crazy. One of Liu Hanqing's high school classmates was a teacher in Dainan. He recalled to reporters the scene after Liu Hanqing returned home after dropping out of school.

"It was probably around 1987. One morning, I heard about his situation. I walked seven miles to their village and found his home. At that time, he was also sleeping. When I saw him When he saw me, I almost didn't recognize him: he had long hair and an unkempt beard. Near the head of the bed was a rice vat with a wooden lid. On the lid were mathematics books, poetry collections, and manuscript papers. In his teens, perhaps he was confident about the future. Not only did he not regret his choice, he was even somewhat proud. I remember that he quoted Socrates' famous saying to me: A life without reflection is not worth living. , I visited his home many times and often invited him to stay at my home. He also cut his long hair and tidied it up. He thought I could understand him and often told me why he was so paranoid. . He said that "number theory" is really magical. Once you get into it, you will feel a great beauty that makes you want to stop. Although I can't appreciate the great beauty, I feel sorry for him, but to be honest, I am obsessed with him. , I am indeed full of respect."

One day two years later, Liu Hanqing told his classmate that his research had produced preliminary results. "He was in isolation from the world at the time. What should he do with this result? The United States already had the Internet at that time. I thought of a classmate working in the United States and asked him to publish Liu Hanqing's paper on the Internet, hoping that it would be published abroad. Expert judgment. Soon, a Norwegian mathematician gave feedback and asked some questions about the third page of the paper. Liu Hanqing gave an answer and asked an American student to translate it, but there was no follow-up."

In order to verify Liu Hanqing's research results, Liu Hanqing's classmate was determined to help him find the top mathematics authority in the country for appraisal. After many twists and turns, I finally found Pan Chengbiao, who is now an academician of the Chinese Academy of Sciences. Academician Pan has been engaged in number theory research for many years. The "Goldbach Conjecture" co-authored with his brother Pan Chengdong is considered to be the most comprehensive and complete monograph on this conjecture in the world. At that time, Pan Chengbiao was a visiting professor in the Department of Mathematics at Peking University. Professor Pan reviewed Liu Hanqing’s paper and responded a month later. "I remember that the main idea of ??Professor Pan's letter was that there is an argument on page 5 that has not been proved, and the following arguments are meaningless. It means that there is no need to read further. But Liu Hanqing believes that it is not impossible to prove that it is not proved, it is just that He has no proof."

His voice

No job, no marriage, no farm work

"Think about the future in two years"

Liu Hanqing is 53 years old. More than 30 years have passed since he fell in love with "number theory". Over the years, he has barely left his village. No job, no farm work, no marriage, no children. Ten years ago, Liu Hanqing suffered from severe anxiety and had to take a large amount of diazepam every day to fall asleep. It was also from that time that he gave up his research on "number theory".

“Have you never thought about finding a job in these years?” The reporter’s question made Liu Hanqing a little embarrassed. He said that a few years ago, the person in charge of the unit came to his home and asked him to go to work. "Later, that person didn't come back, and I didn't go either." Liu Hanqing's classmates told reporters that about twenty years ago, they helped Liu Hanqing find a job as a technician in a heat treatment workshop. "At that time, he was still studying number theory. In less than a month, he came back and said that the factory was noisy and had to work night shifts, and he was used to doing research at night." In 37 years, time has turned a genius boy into what he is today. of low-income households. When communicating with reporters, Liu Hanqing mentioned a certain classmate in his class, "Ten years ago, he was the director of a department of the Aerospace Corporation. Maybe now he is at the ministerial level." "As for the road you have traveled, you think about it. Have you passed?" At the end of the interview, the reporter asked politely. After a while, Liu Hanqing said slowly: "I haven't thought about it, and I don't want to think about it now. Let's think about it carefully in two years." When he said this, he looked at the door like a "thinker" ".
