No, whether it is a normal student or a non-normal student, the teacher's card is valid for life in the whole country, and there is no such provision as continuing education.

Of course, if you have time and experience, it is not bad to continue education and improve yourself.

The teacher's license will not be cancelled because you have not continued education, and your teacher qualification will not be revoked unless you are severely punished for violating the teacher's law or the law, such as serious violation of teachers' morality.
