At present, only Peking University, Nanjing University, Beijing Normal University and China University of Science and Technology have astronomy departments in China, and Nantah is the best in China, so the selection range is relatively small. Moreover, the astronomy department has a high admission score, so you can go to their forum or post it for detailed consultation.
If it is a postgraduate entrance examination, in addition to the above-mentioned schools, there are also some institutions such as the National Astronomical Observatory of the Chinese Academy of Sciences, the Shanghai Observatory of the Chinese Academy of Sciences, and the Purple Mountain Observatory.
