guzheng

The guzheng or gu zheng (, pronounced ), also simply called zheng (, gu means "ancient"), is a Chinese plucked zither. It has 18 or more strings and movable bridges, and the modern guzheng usually has 21 strings and bridges. The picks (called "DaiMao") used by performers to play guzheng are often made out of the shells of hawksbill turtles.
