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 Liu Yue chewed, the more he felt that it was full of mystery and fun. He was determined to "do better than Chen Jingrun".
Liu Hanqing reached the level of obsession. At the craziest time, he forgot to eat and sleep. 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. 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. 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.
Liu Hanqing, who returned to his hometown, let his family down. Neighbors all thought he was crazy. He said that a few years ago, the person in charge of a unit visited his home and asked him to go to work. About twenty years ago, someone 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.
Liu Hanqing now lives in three farmhouses with skylights in Group 5 of Shuangmu Village, Dainan Town, xinghua city City, Taizhou City. I have no skills, I can't do manual labor, I have a job, I can't do farm work, I have never been married, I have no children, and I can sleep only after eating 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. Now, he only lives on the government's monthly minimum income in 400 yuan.
