Teachers had better choose training institutions. If you go to school as a teacher, the higher authorities will give you relevant documents, which will limit your various behaviors. Well, although teachers nominally have a lot of rest time, most of their working hours are over 12 hours, and it is said that teachers can only raise their salaries through lecture experience, professional titles, publishing papers and so on. You are only responsible for teaching in the training institution, and you can arrange the other time yourself.
