"Can China people become teachers in foreign universities after studying abroad?"
It is not easy to answer the question whether this is the case. But at least in Japan. And the professor. Almost without exception, I studied undergraduate, master, doctor, researcher, teaching assistant and lecturer in Japan. . . Yes
Europe and America don't understand, at least in Japan, university teachers = scientific research, don't care how you attend classes, only care about what scientific research results you have. The same is true of doctors. The requirement for doctoral graduation is that the first author's two papers must be published in global authoritative magazines, which means that you must design your own experiments, complete the analysis and summary, and publish them in global authoritative magazines in this field. It is even harder to get a doctorate. I haven't got my salary yet, so I have to bear a lot of mental pressure. Oh, beside the point. In a word, if you choose this road, you will devote yourself to scientific research all your life. Embarrassed, there are scientific research tasks every year. Most of our professors don't have holidays, so they are under great pressure.
"I don't know what are the chances of becoming a foreign university teacher after studying abroad? What major is easier to stay and teach! Which country has the highest probability of studying and teaching? "
This is not good. According to the probability, becoming an overseas professor means having a very bad position, and it also means giving up something of equal value. If you major in science and engineering, I don't know this country.
Generally speaking, the professional knowledge is very poor, and there are outstanding scientific research achievements in the undergraduate master's degree, which can withstand the hard work of doctors, and the chances of staying in school are very low, almost zero.
