Yes, you are right. The academic level of many university teachers is extremely average. Teachers over 45 years old, in particular, have little understanding of this major. You know, these people enter colleges and universities, which is the upsurge of going to sea. Only those who have no skills will become teachers, not to mention masters and doctors. Even undergraduates can stay in school as teachers.
2. Teachers' income is low and they can't concentrate on their majors.
3. The design of school system makes university teachers completely divorced from social reality.
Ask any university teacher what the employment situation of students in his university is this year. What is the average salary? There is a 90% chance that he doesn't know. It makes no difference whether you teach well or not. It is the general trend to muddle along, and it is the dream of university teachers to engage in relations and transfer to administrative posts.
