Is it difficult for Huailai to be an extra teacher?

Not difficult. The supernumerary teacher is a substitute teacher or a private school teacher, which is relatively easy to test, but it is not difficult to get the teacher qualification certificate first. Extra teachers, also known as substitute teachers, refer to temporary teachers who have no career establishment in public schools. They are teachers employed by the government education system outside the financial allocation, that is, post teachers, that is, temporary teachers. Generally, the school recruits itself. Overstaffing means that there is no "hukou" in the unit.
