First of all, there are many people here who make up the numbers. I have been teaching music for many years, eight years. I have an art training class here, so many people learn all kinds of musical instruments, and I know a lot about many musical instruments, because I have opened a musical instrument shop myself.

First of all, among the plucked instruments you mentioned, Qin Qin is relatively simple, but it has been eliminated and is of little use.

Ruan, Guqin, Pipa, Yueqin, among which Ruan and Yueqin are not solo instruments and are basically used in traditional operas or national symphonies, but it is not difficult to get familiar with many national cultures, especially traditional operas. Guqin and pipa can be said to be the most difficult, especially Guqin, which we are still learning at present.

Therefore, I recommend that the introduction of guzheng is simple, but if you play a high-level tune, you need to practice hard. Guzheng is suitable for solo and practical, but it's a bit too demanding for you.

If it is smaller and simpler, I recommend cucurbit silk!
