There is a Eurasian musical instrument store in Yanshikou (Taihua comes out and goes to Yanshikou, upstairs 2), which not only sells all kinds of musical instruments, but also teaches them.

Not bad, it seems to be around 600 yuan. You can go at any time until you learn. Teachers are also very nice and funny, and you are not old. It is said that one of my teachers was a friend of Gou Wei in my performance in Lycra. Not bad.
