At present, many schools have the problem of multi-campus, which is caused by many reasons. First, due to historical reasons, many schools were merged by several schools. The original schools were scattered in different places, and there were different campuses after the merger. In this case, several campuses are generally in the same city. Second, the needs of school development. After the industrialization of education, many schools have improved their grades and their scales have to be expanded accordingly. However, the original land area is not enough, so it is difficult to acquire land nearby, so they have to go to other places for development. In this case, different campuses may be in the same city or in different cities. Third, due to the relationship between industry and region, individual schools set up different campuses at the beginning of their school. In this case, different campuses are often not in the same city or even in the same area. Besides, there are other reasons.

Some schools have different levels of education, and different levels of education are arranged in different campuses. For example, some schools have both undergraduate and junior college students, and the undergraduate students are arranged in one or part of the campus, and the junior college students are arranged in other schools. Some schools arrange campuses according to majors, and different majors are arranged in different campuses. Therefore, the relationship between campus and academic level and specialty varies from school to school.
