When the erhu rubs the strings, it should touch the nails.

There are many kinds of kneading strings, and any method of generating sound waves by constantly changing the length or tension of strings can be called kneading strings. Among them, rolling is the most basic technique, which is a method of rolling strings by swinging the palm up and down to drive the first joint of fingers to flex and extend, so that the fingertips can roll evenly in phoneme to change the string length and generate sound waves.

Scrolling consists of two action processes. The first process is: raise the palm of your hand and straighten the first joint of your finger to touch the string, and then make a sound slightly lower than the pitch baseline; The second process is: lower the palm of your hand and bend the first joint of your finger, and the contact will roll to the fingertip, at which time the sound will be slightly higher than the pitch baseline.

These two processes are so reciprocating that the fingers roll evenly on the phoneme, thus making a string-kneading sound that fluctuates up and down around the pitch baseline. When rolling, the active point of the action should be placed on the back of the hand, and the palm can only move up and down, not inside and outside. The wrist is an action axis, so the wrist must not be stiff.

Erhu industry pays more and more attention to ecological environment protection;

"Gradually reducing the amount of python skin and continuously increasing the amount of bionic skin is the embodiment of social civilization and progress, and it is also the general trend." Huang Quanwu, a professional bionic leather dealer in Wuhan City, Hubei Province, said that at present, "imitation leather erhu" is mainly sold abroad, with thousands of it every year, and the number is increasing year by year. However, the current domestic market demand is relatively small, and it is believed that there will be greater growth potential in the future.

At present, there are 8 erhu production enterprises/kloc-0 in Meicun, which has formed a certain industrial agglomeration effect and has also received strong support from the local government. Zhang Xiaoming, secretary of the Party Working Committee of Meicun Street, said that it is an inherent requirement for the sustainable development of Erhu industry in Meicun to actively implant eco-environmental factors.
