Generally, there is one book, but most of the good medical universities are merged, such as Union Medical College, Tongji Medical University, West China Medical University, China Medical University, Tianjin Medical University, Nanjing Medical University and Chongqing Medical University of Southern Medical University, but there are also two books, such as Xinjiang Medical University and Shanxi Medical University. If possible, Nanjing Medical University is a good choice, so is Southeast University.
