After graduating from middle school in China, he was forced to drop out of school because he could not afford the tuition. Back to my hometown, while helping my father to work, I continued to study and teach myself tenaciously. Soon, he contracted typhoid fever and was dying. He stayed in bed for half a year, but after his illness, he left a lifelong disability-deformity of the left leg joint and limping. He was only 19 years old at that time. In that confused, confused and almost desperate day, he thought of Sun Bin behind Sun Tzu's Art of War. "The ancients can still be physically and mentally disabled. I'm only 19 years old, so there's no reason to give up. I want to replace my imperfect legs with a sound mind! " Young Hua is so tenacious in fighting against fate. During the day, he dragged his sick leg, endured severe joint pain and worked with crutches. In the evening, he taught himself late into the night under the oil lamp. 1930, his paper was published in Science magazine, which alarmed Professor Xiong Qinglai, head of the Department of Mathematics of Tsinghua University. Later, Tsinghua University hired Huawei as a teaching assistant. On the campus of Tsinghua University, where famous artists gather, Hua served as a teaching assistant in the Mathematics Department. He also taught himself English, German and French in four years and published ten papers. By the time he was 25 years old, he was already an internationally renowned young scholar.

When encountering difficulties and setbacks, people with self-esteem and self-confidence can constantly strive for self-improvement, overcome setbacks and failures, and succeed in setbacks and failures. People who lose their self-esteem often give up and degrade themselves when they encounter difficulties and setbacks. People who lack confidence, when encountering difficulties and setbacks, first think that they are dying, thus giving up their efforts. Therefore, it is impossible for people without self-esteem and self-confidence to succeed in their careers.
