In the early days, banhu used silk strings, which could not be pulled without a cap. In modern times, with the advent of Tsunami, it began to gradually break away from the finger cap. But you can't rub your fingers against the string for too long. The author played Banhu in a troupe and performed outdoors in winter. The steel string cut his fingers and dug into his flesh. The tape was stuck, and even the tape sank into the flesh. When pulling Banhu, apply some talcum powder on your fingers to make the situation better. The time should not be too long. As time goes by, some small calluses will form on the tips of the fingers, and the situation will be much better.

Some advanced repertoire cannot be fully performed with finger hats, but for example, when playing banhu in some local troupes, it is best to bring it with you, because in that environment, playing banhu takes too long, which is difficult for your hands. It can't stand that kind of torment. This is also called making up for the loss.
