2. The specific reasons are as follows: the first cello is rarely played directly with fingers, and the wheel finger of pipa is the most difficult to learn. When touching the wheel finger, you should also pay attention to the strength of the whole hand.

3. Because cello and violin are different in size, chord arrangement and chord length, their playing methods are also different from those of China and violin, and they are played between their legs, so the range of physical activity is smaller than that of pipa, which is easier to control.

The cello has only four strings, while the pipa has five or seven strings or more. Melody is wider than cello, which is difficult to master.

5. Cello is relatively mainstream, pipa is relatively small, and the cost of cello training is relatively low.
