Training in teacher training centers in colleges and universities is relatively cheap, so the number of applicants is also very large. The feeling is just reading a book, and finally the scope of the teacher's painting is quite large. Personally, I think it's useless. At present, there are a lot of teacher qualification training in Tianjin, such as Xiaozhuang Academy and Ziguang Education. The main reason is that the scope offered is small, after all, it costs money!
