Ma Touqin is a Mongolian folk stringed instrument. In Mongolian, it is called "Chao Er". It is a two stringed stringed instrument with a trapezoidal body and a handle carved into the shape of a horse's head, which is a favorite instrument of the Mongolian people. The body of the qin is wooden, about one meter long, with two strings. The resonance box is trapezoidal in shape, with a round and low sound, and a relatively weak volume. Legend has it that a shepherd, in memory of a pony, took its leg bone as a pillar, its skull as a tube, and its tail hair as a bow string to make a two stringed qin. He carved a horse head in the shape of the pony and placed it on the top of the handle, hence the name. In the camera, the master demonstrated the delicate process from finding materials to making, allowing us to deeply feel the charm of the horsehead qin.
