If I don’t achieve something on math, I won’t get married; If you don’t promise me, I’ll be single my life, which is the portraiture of all Chen's life. Chen Jingrun, who was a math genius, but failed to be a math teacher in middle school, hence was fired by school. By the way, when you judge a teacher, its knowledge isn’t the only standard, teaching ability is more important. Finally the future mathematician was forced to sell cigarettes and lend comic strip on street. If you want to be famous, you have to be capable and also meet honorable man at the same time. Chen’s honorable man was president Wang Yanan. It was him who brought Chen Jingrun to work in Amoy University.

  Actually chance isn’t rare in the society now. The problem is that there is rarely anyone who can bear the loneliness to do its thing. Chen Jingrun wanted to use all his time to research math regardless day and night. If you want to do something on science, you have to climb cragged mountain road, then you can have hope to achieve something. I always admire those scientist and scholars who can bear the poorness to put its heart and soul to research its field. In the beautiful campus of Amoy University, swimming, dancing, loving, so many teachers enjoyed the colorful life. But all these things are none of Chen Jingrun’s business. Except for daily work, he hide himself at library or in his little room to study and research his math. No one paid any attention to him, no one understood him deeply. He guarded his uncommon holy land silently and lonely.

  In Chen’s head, there was no word insomnia. Insomnia, meant no need to sleep, then he would get up to work. No shrink, no regret, once decided a road, then went ahead without turning around. Temptation, failure, depression, just ignored all of them.

Chen just wanted a little room to research his math regardless of anything else. When he was transferred to Beijing, there was four people in the dorm. So Chen lived in the three-square-meter toilet to research his math alone for two years. He had lived in Beijing for more than ten years and didn’t even have time to visit the Great Wall. Everyone just sees the flower and smile of successful people, rarely sees hard work.

Chen could ate steamed buns with pickle for years, but I couldn’t. Human is different from machine. About a machine, you’ll receive things according to the things your input. But human is different, when you eat nice food, which doesn’t mean producing nice wisdom. Chen could achieve highly on math with so poor life.

There is also the same word. Perseverance is the only way to success. Perseverance can overcome all difficulties such as poor talent, poor life etc. Chen devoted himself to math and was single until he was 45 years old. Just because of this, people started to suspect whether he had physical problem. How many people can achieve this?

When he finally met his woman, but the woman was hesitated. Chen then said stubbornly, “If you don’t promise me, I will be single all my life.” Sometimes, love needs no sweet words at all. Finally the famous mathematician had a warm family to console his lonely soul.
