In Hangzhou, Feicheng Music School is very good. I also studied in Boiling City, but I studied vocal music and often rehearsed with the guitar teacher there. On Saturday night and Thursday afternoon, there are rehearsals of teachers' jazz bands and their impromptu performances with students. The learning atmosphere there is also very good, and the teachers are among the best experienced professional musicians in Hangzhou. I suggest you have a look. It's really nice there. Guitar, especially Mr. Zhu, is quite good.
