So you should at least get a master's degree and have the opportunity to become a university teacher after graduation.
Uncle, when I graduated from college (30 years ago), some outstanding undergraduates in many universities stayed on campus to teach directly after graduation, and then embarked on on on-the-job graduate students. Now these people have become the backbone of college teachers.
Later, with the expansion of colleges and universities and the proliferation of diplomas, many colleges and universities, especially those in economically developed areas, and key universities, graduated with master's degrees is not enough. Originally, only doctors from domestic key universities (so-called 985 or 2 1 1) or even "returnees" from famous foreign universities were needed.
So, you know, if you only have two undergraduate diplomas, it is almost impossible for you to become a university teacher. Even if you graduate from an ordinary undergraduate course and want to be a primary and secondary school teacher in some economically developed areas, you may not have the opportunity. In a primary school in the urban-rural fringe, more than a dozen young teachers have graduated from graduate school in recent years.
Of course, if you don't have a postgraduate degree, but you have made great achievements in a certain field, you may also be specially hired as a lecturer or professor in colleges and universities.
For example, excellent writers, executives of top 500 enterprises, senior engineers of enterprises (especially those with major scientific research achievements or major inventions), super teachers among primary and secondary school teachers, doctors with superb medical skills, artists with outstanding achievements, sports world champions and so on.
For example, many literary works have won the top literary awards in China, and even writers whose works have won Nobel Prize in Literature can be employed as teachers in the Chinese Department of universities. Authors with high level of song creation are employed as teachers of the Conservatory of Music; People who have made many major scientific and technological inventions are employed as teachers by universities of science and engineering, sports world champions are employed as physical education teachers or coaches of sports teams by universities, and so on.
