China's rapid development and achievements, its integration into the world center and its leading position in the world are inseparable from the efforts of China to build outstanding talents. All the achievements made by China were built by scientists. Therefore, if China's talents settle abroad after studying abroad, it means that there is one less talent for building the country. The brain drain in China is mostly due to the poor treatment of the motherland, because a long time ago, China's comprehensive national strength was really not strong, and it was impossible to promise good living conditions. Therefore, the inventions created by scientists under difficult conditions were all based on their patriotism. But at the same time, many talents will choose to settle in other countries. Once in high flyers of Peking University, mathematical genius Zhang was one of them. He said that he would rather wash dishes in America than go back to China. How is he now?

Zhang is an out-and-out Shanghainese with good family conditions. He received a good education from an early age. When he was young, he showed amazing talent in mathematics. After the college entrance examination resumed, he successfully passed the college entrance examination, entered Peking University and became the high flyers of Peking University. He is excellent in all aspects, proficient in music and literature, and has also become the president of the student union of Peking University. Besides, he is a basketball fan. Feihang likes watching NBA, which may also be the reason.

When he was in college, his talent in mathematics showed incisively and vividly. He is very sensitive to numbers, so his tutor also saw his talent in this field. Therefore, he was a genius in the department of mathematics at that time. He always comes first in exams and never comes second. After graduating from undergraduate course, he was admitted to graduate school very smoothly. After graduating from graduate school, he unexpectedly received an invitation from a professor at Purdue University in the United States, and went to the United States to study for a doctoral degree ... During his doctoral period, he set himself the goal of cracking the Jacobian conjecture. When he graduated from the doctor's office, he announced that he had cracked the Jacobian conjecture, but because of data problems, there was a contradiction with his tutor, because his doctoral thesis was also postponed, and he did not officially graduate from the doctor until seven years later.

After graduation, he didn't receive a recommendation letter from his tutor, so he couldn't move in the United States and his life was very difficult. In the most difficult years, Peking University offered him an olive branch, which he refused. He said that even if I washed dishes in America, I wouldn't go back to China to be a teacher. It was not until a new breakthrough was made in Riemann's conjecture that he gave up, and his achievements filled a long gap. Later, it was not recognized by the world until 20 18.

Many people asked him why he didn't want to go back to China. He said that there is no learning and innovation environment in China, so he said that if he returned to China, he might not have this result. What do you think of this?
