The East Campus is mainly composed of freshmen from Chemistry College, Law School, Engineering College, Environmental Sanitation College, Soft College, Medical College, Hospital, Zhongshan Medical College, Guanghua School of Stomatology and Public Health College. There are many liberal arts schools in South China, and most of them are graduate students, and most of the undergraduates are in university towns. The northern school is only related to medicine, mainly Zhongshan medicine, and of course Guanghua dentistry and public health. After sophomore year, medical students are studying in the North School, and graduate students are also in the North School. There are many affiliated hospitals near the North School. Zhuhai is newly built. Eight years before clinical practice, some biology departments were in Zhuhai. It seems that Lingnan Business School is also in Zhuhai.
I'm a medical student, so I can only give a rough idea. Some departments may make mistakes.
I hope it helps you.
