The problem is that you come out to find a job after graduation, which is a big problem.

However, if you go first, you can use the time of military training to find out which majors are good and which majors you prefer.

Then you can change your major. We are not very strict in South China.

Once you are ready to improve your major, you should do it as soon as possible. Although the basic courses are almost the same, there are differences after all, otherwise it will be the worst to change halfway in the future.
