I don't know which city you are in. Beijing, Tianjin, Guangzhou, Wuhan and other big cities have relatively good training courses. In fact, as long as the place to go is qualified, the key is to see the teacher. Beijing National Training Certification Center is a very authoritative training institution, with training arrangements all over the country throughout the year.
