Can a Korean PhD graduate return to China and become a teacher? Is it really the only way to become a teacher? I am majoring in accounting in the Department of Business and have a master's degree.

What kind of teacher do you want to be? It is very difficult to get into university now. You should look for one a year before you graduate with your PhD. It is basically impossible to find good schools in big cities. , unless your family is very powerful. Otherwise, there is no problem of location at all. I recently heard a university president say this to a student looking for a job. It's a luxury car. But now their school is full. Can't stop. Want it very much. But he was asked to find another job. Very funny and realistic. You need to look for it early. Originally, there was no need to go to school or graduate school for accounting majors.
