It is said that teachers in many educational institutions have in-service teachers, but most of them are part-time teachers, not teachers. There is nowhere to go after graduation, so go to a training institution. You go to one and ask if the teacher is an in-service teacher, and people will definitely say yes. Think about it, there are so many teachers doing education. Most of the teachers of Only Education are on-the-job, and I also have friends in them. (Ordinary people, I won't tell him)
