Can graduate students from Guangdong University of Foreign Studies become university teachers? (It is not necessarily a school with two majors, but a college. )? )

I don't think so. Now all these places need a "local tyrant certificate", not only the graduate diploma, but also the place where you graduated from undergraduate course, which is what you said: 2 1 1, 985 school. There is also the need to see high school. If you are an ordinary high school graduate, it is not necessary. So it is difficult to be a high school teacher now, let alone a university teacher. You can only try this. You may be lucky to get in.
