Zhengzhou Qin-making is not particularly famous, but Kaifeng has good musical instruments. You can go and have a look. All kinds of styles are ok, but it's best for someone to help you choose the guqin, with the emphasis on timbre. Yangzhou's guqin is famous all over the country. I suggest you be careful. If you buy a piano practice, it is best not to be less than 4000 yuan. Of course, if you want to use it temporarily, you can also buy a piece of paulownia, 1000 yuan or so. The new Chinese fir will not be too expensive, but at present, paulownia is the majority of the piano, and the old Chinese fir is the main Chinese fir. In fact, the quality of Chinese fir in guqin is better. If it is not paulownia or phoenix tree, there is nothing good. Paulownia is playing more and more. The sound quality of new Chinese fir will not be very good.
