Junior college can take the teacher qualification exam, primary school can take the exam, but teachers have to take the undergraduate exam. Isn't this a conflict?

College students who have obtained primary and secondary school teacher qualification certificates can apply for teacher establishment.

With these two basic conditions, you can apply for teacher establishment.
