It's better to learn guitar or go to a special training institution. I have been to a music store, and the teacher sold the piano just after a few words. Customers always interrupt in the middle. Teaching is not very patient.

The Baroque College in Haidian District is good. The teachers are very attentive and unlimited times are free. It's okay. You can practice with everyone. I learned it there last year, and now I can watch many songs by myself. You Baidu "Baroque College" and it will come out.
