The corbel is called "Guoji" in Dong language. It is mostly used to play and sing love songs, bass playing, soft singing, and unique charm. This qin and pipa ensemble are used at weddings to convey a warm and festive atmosphere.

When playing, you can sit or stand. In the sitting position, use a slightly larger corbel, with the lower end of the case between your knees, with the piano facing forward, hold the piano in your left hand to press the strings, and hold the bow in your right hand to play outside the strings; in the standing position, use a slightly smaller corbel. , Put the end of the qin between the left shoulder and the left chest, with the qin face up, hold the neck with the left hand, press the strings with the index finger, middle finger and ring finger, and play the bow on the strings with the right hand.

This method of playing is extremely rare in the folk strings of various ethnic groups in my country, and it is somewhat similar to the posture of playing the violin. The corbel can also be played while walking.
