The following is my understanding of the beginner erhu:

1. Long, short, continuous, sudden, shaking, jumping and throwing, arranged in an orderly manner.

2. The piano body is stable and slightly tilted to the left, which is conducive to stable operation.

3. The wrist is lifted horizontally and flexibly, and the string is held on the piano barrel.

4. Wrap the piano in your left hand and be natural.

5. Erhu intonation is difficult to master, and the interval relationship should be clarified.

6. The beat of notes should be accurate and the change of length should be clear.
