The genius boy who was admitted to Harbin Institute of Technology at the age of 16 has now become a "low-income household". What happened later?

Wu, a girl from China Renmin University, has never found a suitable job after graduation. Finally, she went to the mountainous area in northern Jiangxi and became the mother of six children from a destitute family, which became a hot topic of social concern. The reporter recently learned that there is also a famous student in Taizhou who is similar to Wu.

16 years old was admitted to Harbin Institute of Technology (hereinafter referred to as Harbin Institute of Technology). Since his junior year, he relaxed his professional study because of his obsession with mathematics, and finally failed to get his diploma. After returning home, he continued to indulge in his "mathematical research" for more than 20 years. Finally, he chose to give up. He has no skill and can't do manual labor. Now, he only lives on the minimum living allowance of the government in 400 yuan every month.

He, Liu Hanqing from Class 8095 of Harbin Institute of Technology, now lives in three huts with skylights in Group 5 of Shuangmu Village, Dainan Town, xinghua city, Taizhou. After the Dragon Boat Festival holiday, the reporter approached Liu Hanqing to explore the sad story of a "gifted teenager" becoming a "low-income household".

Liu Hanqing lives in this shabby house.

At present, he lives in poverty.

"400 yuan a month is enough."

One morning after the Dragon Boat Festival holiday, the reporter and his party walked about 4 kilometers east along the "Dai Nan" exit of the quiet salt expressway and arrived at Shuangmu Village where Liu Hanqing was located.

Since Liu Hanqing didn't have a mobile phone and didn't know where his home was, the reporter and his party turned to Shuangmu Village for help. Enthusiastic village accountant Song Yinfeng took us as a guide. Through several wide or narrow alleys, Song Yinfeng stopped in front of a courtyard. "This is Liu Hanqing's home."

It is the door of a quadrangle, instead of leaving an aisle between two foundation bricks, standing a wooden board on both sides of the aisle, and then crossing a wooden board, it becomes a "door" Walking into the courtyard gate, the reporter saw an old three-bedroom tile house. You can tell the age of the house from the broken plastic film on the window of the East Wing. The door of the main room is wide open, shoes, worn-out clothes, all kinds of bottles and cans ... are full of sundries, making people have nowhere to stand. There are some lights 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, the unyielding Song Yinfeng went into the house to look for it again. This time, he found Liu Hanqing sleeping in the bed in the east wing.

Liu Hanqing in front of the reporter has fair skin, a large forehead and a pair of nearsighted glasses above the bridge of the nose. Liu Hanqing said that at present he lives alone in this house, and his parents are old and live in his brother's house. In the kitchen, the reporter saw two iron pots, one with a zongzi, an egg and a little porridge in the other. Liu Hanqing said that this was left by his mother. "I will eat whatever she does. I don't eat much. "

Liu Hanqing has no job and can't do farm work. He has never been married and has no children. He can only sleep by taking valium every day. A few years ago, the government gave him a minimum living allowance, and he received a living allowance from 400 yuan every month. "Can you support yourself with 400 yuan a month's living expenses?" "I can't spend any money. 400 yuan a month is enough. " Liu Hanqing's answer was beyond the reporter's expectation.

Once he was in high spirits.

/kloc-entered Harbin Institute of Technology at the age of 0/6, and an article fascinated him with mathematics.

1980, Liu Hanqing, 16 years old, was admitted to the Department of Building Materials of Harbin Institute of Technology with an excellent score of 398.5. In the eyes of many people at that time, he was a "genius" in his teens and was extremely clever. After entering Harbin Institute of Technology, the future is limitless. The reporter learned that Harbin Institute of Technology belongs to the Ministry of Industry and Information Technology and is one of the first universities to enter the national "2 1 1 Project" and "985 Project". Many top talents in China's aerospace field are from Harbin Institute of Technology.

In the first two years of college, Liu Hanqing achieved excellent results and was well received by teachers. Liu Hanqing's fascination with mathematics is influenced by Xu Chi's reportage Goldbach Conjecture. Goldbach's conjecture was published in 1979, which caused a sensation throughout the country. At that time, Liu Hanqing was preparing for the college entrance examination and didn't take it to heart. It was not until one day of his junior year that he came across this article in the school library. By this time, the "Chen Jingrun fever" of the whole society had passed. Maybe this is an arrangement. Fate opened another door for him. He has a talent for mathematics, because this article plunged into the ocean of "number theory" and determined his own research direction: the distribution of prime numbers in natural numbers. The more he chewed, the more he felt the mystery and interest, so he decided to "do better than Chen Jingrun".

Liu Hanqing is obsessed with "the study of mathematics". He recalled that in the craziest time, he had forgotten all about eating and sleeping. He thinks eating is a waste of time and only sleeps for two hours every day. Accordingly, he became less and less interested in the major of heat treatment, and was only fascinated by his "mathematical world". After the dean and counselor found out, they talked to him and let him base himself on his major. If you really want to learn math, you must first get a diploma. But he didn't listen to what the teachers said. When I was in senior three, I couldn't graduate because I failed many courses. Because of "love of learning", I couldn't get a diploma, which was rare at Harbin Institute of Technology and even the national universities at that time. Harbin Institute of Technology gave him a year from the perspective of caring for students. However, this year, Liu Hanqing is still studying his "number theory". "It was like being possessed." Liu Hanqing said.

Without a diploma, Liu Hanqing will not enjoy the national "package distribution work" treatment. Many of his classmates have been assigned to the Ministry of Aerospace Industry or subordinate enterprises.

1985, a farmer's father, Liu Hanqing, picked up his son's luggage from Harbin with the pole he sent to pick up his luggage when he was in college.

Crazy "chasing the number" for more than 20 years

No one realizes mental anxiety.

Liu Hanqing, who returned to his hometown, let his family down. Neighbors all thought he was crazy. One of Liu Hanqing's high school classmates, who worked as a teacher in Dai Nan, recalled to reporters the scene after Liu Hanqing left school.

"About 1987. It was also a morning. I heard about him, walked seven miles to their village and found his home. At that time, he was also sleeping. I hardly recognized him when I saw him: long hair shawl and unshaven beard. There is a rice jar near the bedside, and the cover is made of wood. On the lid are math books, poems and manuscript paper. He was in his twenties at that time. Maybe he is full of confidence in the future. Not only did he not regret his choice, but he even felt a little proud. I remember he quoted Socrates' famous saying to me at that time: a life without thinking is not worth living. After that, I visited his house many times and often invited him to live in his own house. He also cut his long hair and tidied it up. He thinks I can understand him and often tells me why I am so paranoid. He said,' number theory' is really amazing. If you put yourself into it, you will feel a great beauty and make you want to stop. Although I can't appreciate the great beauty, it's a pity for him, but to be honest, I really have full respect for his persistence. "

One day two years later, Liu Hanqing told his classmates that his research had achieved initial results. "He is isolated, how should I deal with this achievement? At that time, the United States already had the Internet. I thought of a classmate who works in the United States and asked him to publish Liu Hanqing's paper online, hoping to get the judgment of foreign experts. Soon, a Norwegian mathematician got feedback and asked questions about the third page of the paper. Liu Hanqing answered and asked American students to translate. But after that, there is no more. "

In order to verify Liu Hanqing's research results, Liu Hanqing's classmates are determined to help him find the top mathematical authority in China for identification. 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 the study of number theory for many years, and the Goldbach conjecture co-authored by 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 in Peking University. Professor Pan reviewed Liu Hanqing's paper and gave a reply a month later. "I remember the effect of Professor Pan's letter that there is an argument on the fifth page that has not been proved, and the next argument is meaningless. It means you don't have to look down any more. However, Liu Hanqing believes that it is not impossible to prove without proof, but he has no proof. "

His voice

No job, no marriage, no farm work.

"Think about your future in two years."

Liu Hanqing is 53 years old this year. More than 30 years have passed since he fell in love with number theory. He has hardly left his village these years. No job, no farm work, no marriage, no children. 10 years ago, Liu Hanqing suffered from a serious anxiety disorder and had to eat a lot of valium every day to fall asleep. It was also from then on that he gave up the study of "number theory".

"I haven't thought about looking for 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 a unit visited his home and asked him to go to work. "Later, that person didn't come again, and I didn't go." 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. He came back in less than a month, saying that the factory was noisy and needed to work at night. He was used to doing research at night. " Thirty-seven years have passed, and time has turned a gifted teenager into a low-income family today. When communicating with reporters, Liu Hanqing mentioned a classmate in the class. "Ten years ago, he was the head of a department of the space company. Perhaps, now he is a minister. " "Have you thought about the road you have traveled?" At the end of the interview, the reporter asked diplomatically. After a while, Liu Hanqing said slowly, "I didn't think about it, and I don't want to think about it now. Think about it after two years. " When he said this, his eyes looked out of the door like a "thinker".
