[0002] Guzheng, also known as Hanzheng, Qinzheng, Yaozheng, Luanzheng, and also known as the "king of all music" and "Oriental piano", is a zither instrument among the traditional musical instruments of the Han nationality in China. It is a plucked instrument and one of the unique and important national musical instruments in China. As early as the Spring and Autumn Period and the Warring States Period, it was popular in Shaanxi and Gansu. It is often used for solo, duet, instrumental ensemble, and accompaniment of singing and dancing, opera, and folk art. During the production process of Guzheng, in order to facilitate normal drilling of the Guzheng so that its strings and other components can be installed later, a positioning device is used to limit the position of the Guzheng.
