When there are similar quality problems in the management of college teachers
Complaints can be made at different levels.
After all, university teachers are all led by the school party committee. You can complain anonymously to the principal's email address, which I think will get good results. If the actual effect is not achieved, you can complain about the glorious image of your university teachers in official website, the education department. I think your school will attach great importance to this situation, which is really outrageous. . . .
I wish you success.
