First, after the merger of schools, such schools naturally became branch schools because they were not together before. For example, after the merger of 1999, Shanda is now divided into Yi Shan, Gong Shan South School, Shanda Old School and Shanda New School. This is the case in the North Campus of Sun Yat-sen University and Sun Yat-sen Medical College. Second, for various reasons, new campuses have been established, such as Sun Yat-sen University, and a new campus has been established in the university town. Jinan University is divided into headquarters, and the Chinese Language Institute and Shenzhen and Zhuhai campuses have their own specific reasons, such as the unique advantages of Jinan University and the policy of running schools for overseas Hong Kong, Macao and Taiwan.

Like a merged school, its independence is still quite strong. Generally speaking, after a medical college or medical university is merged into a comprehensive university, it will often be renamed as the medical college or medical department of a university. So naturally, the original campus remained relatively independent, only with a different brand. Similarly, some colleges and universities often put similar majors in one campus after integrating and reorganizing resources. On the other hand, universities often build new campuses after large-scale enrollment expansion, which will transfer some majors and freshmen to new schools. There are also graduate students and undergraduates trained in different campuses, such as Southern Medical University and Zhejiang Chinese Medicine (or Nanjing Chinese Medicine). In fact, the reason why universities are divided into campuses is to expand their scale (the headquarters cannot be filled).
