Actually, being a courier is very simple. As long as you are willing to endure hardships and have patience, you can be a good courier. There is a senior in our school who has been working in the express delivery site since his sophomore and junior year. When he graduated, he directly chose to start a business and opened his own express shop. It's getting bigger and bigger now.
There is such a courier brother, and Bian Xiao admires him. His name is Yu Jianchun. Yu Jianchun majored in animal medicine. After graduating from junior college, he worked as a packer and courier in a logistics company. Yu Jianchun, who has only a junior college diploma, has been wandering for more than ten years, working hard with both hands to make a living. He has done a lot of work, both at home and abroad, but the only constant is his love for mathematics. Every time after work, as long as he has time, he will read some books about mathematics, and he will draw inferences while reading them.
Yu Jianchun's love for mathematics is not only his own internal digestion. Every time he discovers a new problem, he will write to some scholars in the mathematics department of the university, trying to verify whether his findings are correct, but each letter has failed to get a response. Nevertheless, Yu Jianchun's love for mathematics has not been affected. He still studies mathematics whenever he has time, and writes letters to various scholars when he finds something new. In fact, Yu Jianchun was not good at mathematics when he was a child, but he was very interested in mathematics.
This kind of day lasted until the day of June 2065438+2006. Yu Jianchun, who is at work, received a reply from Professor Cai Tianxin of Zhejiang University. Yu Jianchun was surprised when he received the reply, because the letter had been sent for more than 20 days, and he thought there was still no reply. Professor Cai Tianxin invited him to Zhejiang University in his letter and invited him to introduce his research results to the students. These students are not ordinary students, but doctoral students!
When talking about sharing his research results on the platform of Zhejiang University, Yu Jianchun said that he was very nervous and his hands were shaking all the time. Fortunately, he adjusted quickly. His sharing lasted for an hour and a half, and he showed his five new discoveries in mathematics on the blackboard. Among these findings, Professor Cai Tianxin thinks that the most valuable is the judgment of "Carmichael number".
In the eyes of Professor Cai Tianxin, Yu Jianchun is different from other ordinary science lovers. When talking about Yu Jianchun, Professor Cai Tianxin said: What makes him different is his bumpy past experience, which makes him more modest, cautious and practical than ordinary people, while Yu Jianchun is more worthy of respect for his love of mathematical science and his persistence in research.
Since then, Yu Jianchun has even solved a century-old mathematical problem by virtue of his unique mathematical talent and his love and persistence in mathematics. Yu Jianchun has attracted more and more attention, and many media have made various reports on his deeds.
Yu Jianchun, who is concerned and affirmed, keeps a modest and steady attitude as always. He said that his theoretical foundation is weak and he needs more professional and in-depth research and systematic study. Such an excellent person is still so humble, and Bian Xiao really admires him more.
