First, the epidemic in 2020 led to the return of students. 2020 is an eventful autumn. The epidemic at the beginning of the year led to industrial recession and economic stagnation for almost a year. With the gradual control of the domestic epidemic in March and April, the foreign epidemic has just begun to break out. Up to now, the epidemic situation in many foreign countries is poorly controlled, resulting in the safest country in the world. Now it's China, and it's too dangerous to stay abroad. Returning home can only guarantee your own life safety, so many international students return home.
Second, the domestic research environment and the level of scientific and technological development are close to those of foreign countries. With the progress of science and technology and the development of society, the domestic scientific research environment and the level of scientific and technological development are no longer far behind foreign countries as they were at the beginning, but catch up with each other. Therefore, a considerable number of international students now choose to return to China for development because the domestic scientific research environment and the level of scientific and technological development can provide them with a better scientific research atmosphere and place. In this case, there is no need to stay abroad.
Third, the treatment at home is better than that abroad. Because the country is now vigorously introducing talents from all walks of life, the national policy is quite friendly to many students studying abroad. For some big cows with scientific research achievements, they have offered very generous conditions such as high salary without hesitation. Therefore, many international students are attracted by the generous treatment at home and choose to return to China instead of staying abroad.
