First of all, you should apply for the clinical medicine major of medical university, and the assigned hospital can become a plastic surgeon if it has plastic surgery. Now the undergraduate course can't enter a big hospital, so it's best to continue the postgraduate entrance examination and block the doctor's degree after the master's degree. It is possible to enter a well-known big hospital. As for opening a hospital, you don't have to go to college, just have money. When you become a plastic surgeon, you can't run a hospital without money. Two different things.

If in doubt, please ask.
