Difference between erhu bow and banhu bow

Haha, I'll answer you, I'm a student of both majors. First of all, the erhu bow is thinner, and the banhu bow is relatively thicker. This refers to the shaft of the bow. Then there is not much difference, in fact, although it looks almost the same, but pull the erhu and plate beard when our hand strength is not the same, the plate beard requires more power.
