I don't know when it started. Studying abroad has become a necessary process for intellectuals to improve themselves. For many people, studying abroad is like coating a layer of gold on the basis of your original knowledge, which will make you different from others in an instant. In today's China, families with enough money will support their children to study abroad for a period of time, and even families without enough money will fully support their children to study abroad. I have to admit, those who have stayed in school sound much better than those who have not. But at the same time, the life safety of international students abroad is also very worthy of our attention.

In 2008, a China math genius was found dead under the scaffolding of a church next to the University of Chicago. The news made many people feel very sad and sad at that time, and they mourned the math genius one after another. However, after investigation, the American police even said that the math genius chose to commit suicide because of depression. Obviously, this explanation is unbelievable to all China people. At one time, many people speculated that it was fabricated by the United States. In fact, mathematical geniuses should have been framed a long time ago.

Ren Wei, 1982, a native of Guizhou, has been a clever boy since childhood. Ren Wei, who originally lived in Guizhou, followed his parents to live in Shanghai in order to make a living. In primary school, Ren Wei participated in all kinds of mathematics competitions on behalf of the school, and always achieved excellent results. With such excellent math scores, Ren Wei's parents soon understood Ren Wei's math talent. Originally, parents who were not rich, in order to make Ren Wei give full play to his talent in mathematics, tried their best to work despite the difficulties in life, so that Ren Wei could have better learning resources and get better academic results. Ren Wei, who is gifted in mathematics, is a scholar who has won a prize, and she is soft. At the age of five, she won the first prize in the Olympic Mathematics Competition held in Shanghai. At the age of nine, Ren Wei had already entered high school. After graduating from high school at the age of fifteen, he decided to study abroad under the consideration of his family and Ren Wei. Ren Wei chose the University of Chicago.

During his school days, Ren Wei's talent in mathematics was fully exerted. During his undergraduate and postgraduate years, he was studying' grey mathematics'. Ren Wei's mathematical talent has played a great role in the study of' grey mathematics', so Ren Wei's research has also made considerable achievements and attainments. Ren Wei has always maintained a serious and down-to-earth attitude in the research process. Ren Wei knows that' grey mathematics' can be applied to military science and technology, so this research is very important for China. Ren Wei is different from most international students. While others are thinking about how to settle down better in a foreign country, he is preoccupied with how to serve the motherland after his studies. Ren Wei was very happy when he learned from his teachers and classmates that he could go back to China.

However, the tragedy happened in the happiest period of Ren Wei, and Ren Wei died at the University of Chicago. This is a very sad news. Everyone has left, and the official news has come out. Whether it is true or not, we can't pursue it. We should learn from it, and partners who study and live abroad must protect themselves.
