If you are going to learn guzheng, I will give you some suggestions for your reference:
First of all, it is best to choose one-on-one teaching. About 50 yuan per hour. The advantage of one-on-one teaching is that the teacher will make a teaching schedule that is completely suitable for you according to your learning situation. An hour's study time belongs entirely to you. And if you choose one to many, that's not good. Teachers should consider the overall learning situation and relatively ignore your situation.
Secondly, choose the piano, and the price difference of the guzheng on the market is too big now. It is not recommended to buy things that are too cheap. This kind of piano has a bad timbre, which will affect your study. If the conditions are ok, you can choose a 2-3k piano. This kind of piano can be studied for 10 years, 20 years. There is no need to be too good. It's fun after all.
