ancient Chinese struck half-tube zither, now obsolete. Early forms had five strings that appear to have been struck with a bamboo stick. The instrument was narrow and slightly convex on top, and the strings were passed over bridges (possibly movable) at both ends. Surviving examples range in length from about 93 cm to about 118 cm (36 to 46 inches). It was one of several zithers used in ancient China; others included the qin, se, and zheng, all of which have remained in use.
