Xinghai Park has compound vibration. The teacher is very good, but the tuition is a bit expensive. Gospel video stores also have teachers, which can be cheaper. I am familiar with the first one, and I met the second one when I went to the music store. Personally, I think I can trust you. There are many musical instruments in Dalian, but I am not familiar with them, so there is no conclusion. Alto and the like are old brands in Dalian, so it's better to know more about them. As for the cheaper ones, I think it may be that the teachers' own ability is limited, and some even lack professional ability (some self-study has become very powerful, but you may not be able to tell the difference without learning something). So novices may take detours and delay their youth. Do more research ~
