Study hard after entering the university, and you will win the opportunity to change your major if you get good grades. Generally, it needs to be ranked before the major (different schools are different).

If you want to go to graduate school, many schools pay more attention to civil engineering, which belongs to the engineering application category and the treatment is relatively better. Chemical engineering belongs to a relatively theoretical discipline, not to mention being ignored. If you want to study, you need to be very focused on academics, and you can tolerate loneliness and exaggeration. Employment is basically a theoretical research post. Of course, the salary is not high at first, but when you are older and have experience, you can get good treatment.

If you only want to study undergraduate, your major will not be too relevant to your future work. However, in order to prove their ability and serious attitude to the work unit, it is suggested that you should study hard in any major. If you are looking for a job, it is similar, mainly depending on your ability, and of course your opportunities (for example, some consulting companies just need students with chemical background).
