If you want to be a university teacher, you must have a high degree certificate. The minimum threshold for a better university is a doctor or even a postdoctoral fellow, which is a hard requirement, while ordinary universities only need to meet the postgraduate master's degree certificate and some related examinations to be employed.
Second, becoming a university teacher requires a teacher qualification certificate.
Teacher qualification certificate is a certificate that every teacher must have. Its function is not only a certificate, but also a test of teachers' quality. Without a teacher's qualification certificate, you will not enter the professional threshold of teachers, because this is the minimum requirement and threshold for being a teacher.
Third, it is also one of the conditions for university teachers to evaluate their academic research results.
If you are a teacher, you need to know a lot about a field, so that you can do research and achieve certain research results. The deeper you know about a teacher's teaching level and his professional foundation, the better for yourself.
