Generally, you won't change your major if you go there. It is estimated that this is a very strong major. There are basically two ways. If there are experimental classes, there are related categories when applying for the selection exam, and they will be automatically transferred to major categories after the school starts. The second way is to change majors after freshman year (freshmen are all studying basic courses, and science and engineering majors are not too bad), and you can apply for top percentage.
