Qin Xue Jian Bian has a lot of information, from piano body, fingering, gestures to music score, but it is two volumes, and the characters are copied by hand in traditional Chinese characters. It may seem a little difficult, and beginners are not very good at mastering it, but it is still recommended. At the same time, I think this set of books can really be used for a long time, not to say that it will end in one stage.

I don't know, I haven't seen it, but it sounds like a time-honored version. Maybe one of the two is enough.

However, it is recommended to buy one with the above, because it is written by the current teacher, which is more suitable for teaching, easy to understand and looks very clear. The disadvantage is that you need this kind of book, but it won't last long. There aren't many books.

In addition, it is recommended to have a staff member who collects scores.

The most important thing is to find a teacher. You can have a CD, but the CD can only be read, can only be imitated, and can't correct your mistakes. Your imitation may not be right. Teachers are very important.
