There are many places in Guiyang, so it's hard to say which one is good. There is a relatively concentrated area under Wandong Bridge. As far as I know, the training courses of teachers Huang and Yang Yinglin are more practical. Teaching is serious and there are not many students. A teacher can't take care of too many students. Some facades have many children all day, and the effect is different. It's okay to practice a little foundation. If you really want to learn some essence, you really need to find a good teacher. Anyway, have a good visit yourself.
