Yu Jianchun was born in Xinyang, and his parents are hardworking farmers. When he was at school, his grades in both Chinese and foreign languages were a mess. Only in mathematics does he have a rare talent. However, the excellent results in mathematics alone can hardly save his achievements in all subjects. Moreover, at that time, China's education had not started to implement the independent enrollment system, so it was difficult for many partial subjects and eccentric talents to get better education and training.
Therefore, after the senior high school entrance examination, Yu Jianchun was not admitted to ordinary high schools. He had to choose to enter vocational high school, and there was no miracle in the college entrance examination. He was unstable, and only scored more than 300 points, far below the undergraduate admission line of that year. He entered a university to study logistics.
After graduating from college, he worked hard as a packer in a logistics company, but since he went to work, he began to regain his previous hobby, that is, mathematics, which is a headache for many people. In his eyes, math is like watching TV and skateboarding. This is a relaxing entertainment. He comes home every day, and after getting rid of the fatigue of work, he will wander in the world of mathematics.
Once in the process of studying mathematics, he stumbled upon a new algorithm that could identify Carmichael numbers. When he cracked the algorithm, he worked hard in mathematics for eight years. He wanted to share the new algorithm with others, but no one listened. Later, he was laid off by the logistics company, became unemployed, and began to run around to earn money.
Occasionally, when he has a rest in his busy work, he will visit various university campuses. Moreover, he insisted on querying the public mailboxes of university professors online and sending them emails, which recorded his speculation about carmichael in detail. At first, these mails were thrown into the sea like stones without causing a ripple.
Until one day, he received a reply from Cai Tianxin in the mailbox. Who is Cai Tianxin? He is a senior professor at the School of Mathematics of Zhejiang University. He thought that Yu Jianchun's thought was really well founded, so he specially invited him to attend the digital seminar.
A few days later, in the brightly lit lecture hall of Zhejiang University, Yu Jianchun presented his ideas to the professors in the audience. He was a little shy at first, but later he got better and better and began to interpret his number theory. The professors who listened to him nodded from time to time, and they were surprised at his identity after all. He looks simple in clothes, but he is very hidden.
According to the discussion between Cai Tianxin and several other professors, they don't agree that Yu Jianchun's research and talent in mathematics have made him gain something. Although he has never received professional and systematic training and knowledge input, many of his research results today are of theoretical significance and practical value, so that some of them have reached the master's stage.
Yu Jianchun's growing fame has disturbed the CCTV record channel. He thinks that his story can be excavated as an in-depth theme, which can prove to the greatest extent that one's efforts are endless. When a person works hard, his life has infinite possibilities. This inspirational life documentary was sent away as soon as it started broadcasting, which made more people know about Yu Jianchun's deeds.
Everyone's life will be dark, but occasionally putting a little light into darkness will actually save a person, make people live to death and welcome the light nirvana. In Jianchun's life, this light is mathematics, which brings him confidence and makes him as bold as Mount Tai as an ant.
Today, Yu Jianchun is employed by a high-tech company and becomes a data analyst. His life has changed, from an ordinary packer to a senior researcher in the company. In Jianchun's life, he used to be a worker, but he dreamed of becoming a horse and traveling around the world. Ten years of diving, has it ever been famous and fruitful? After the disaster, he finally showed his fingers and knocked on the hall of mathematics. His life can be described as a model of ordinary people's counterattack.
