How to tune the guzheng if it is not accurate?

The tuner is not recommended. After all, Andhadhun's tone is too rigid to listen to.

The pitch moves to the right and the pitch moves to the left.

Always hold the piano code in your hand, don't let go, don't move and let go of the audition. It's too much trouble.

Combine the first few tones to find the most harmonious sound.
