It seems that the four schools you mentioned are all two. If you go to a second school, your major is really important. First of all, you should like it yourself, at least you can learn it. Secondly, if this school is an ace major, the teaching staff will be good. Otherwise, other majors are not serious and feel like gangsters. Really bad, really a waste of your youth!
Let's talk about Changzhou University again. There are two campuses, Wujin Campus and Baiyun Campus. The Institute of Chemical Engineering and other hospitals are located in Wujin Campus, which is far from the urban area, but the transportation is convenient. Half an hour from downtown! But the environment is good, it is a new campus, the facilities are relatively new, the accommodation conditions are good, and chemical industry is also very fast in our school!
There is only one mechanical engineering college in Baiyun campus, which is quite old. My classmates live there during the holidays. It is said that the windows are all like in the 1990 s, which seems quite miserable! I just wandered around the campus. It's very small! Like high school! But it's better to be professional!
