What music scores do most musical instruments in China use?

Folk music is mostly simple music. If you don't consider more formal bands (mostly staff), if you are unfamiliar with staff since childhood, most people will like to use simple music. Because the range of folk music is not very wide, simple notation can also cope. But some musical instruments, such as piano and harp, have a wide range, so it is impossible to use notation. We should consider it from this level, not because there are any special rules, but because some musical instruments can use notation, and some can only use notation. As for the music said upstairs, the principles of music scores and staff in western musical instruments are similar. Guitar uses staff, but it is also based on the characteristics of guitar, combined with staff or staff. I believe that the staff is not a brand-new music. Drum has a drum score, but it is obvious that what is a line or not depends only on the difference on the surface.
