Hello, here's the thing There are differences in training schools in this area, and there is no uniform charging standard. If you want to study semi-permanently, it is recommended to go to a regular school, choose some schools whose formal learning ability suits you, and choose schools according to your own budget. However, there are many schools, so you can't register blindly by online information. It is recommended to have a certain understanding and learn more about the teaching atmosphere, teachers, school environment and so on.
