Students with Hong Kong identity cards need to take the Hong Kong Teacher Qualification Certificate when they return to Hong Kong as teachers.

Without a teacher qualification certificate, you are not qualified to engage in the teaching industry, so you can't be a teacher. However, when recruiting teachers in some areas, the conditions will be relaxed, that is, some fresh graduates can teach in schools without teacher qualification certificates, but they must obtain teacher qualification certificates within the prescribed time limit.
