Bone board, Hui and Han people strike each other's body music instruments. The Hui people call it sheep incense board and sheep fan board. Popular in the vast areas of Ningxia, North China and Northeast China.

It is made of cattle and sheep hip bones, in the shape of a fan. The beef hip bone is generally about 34 cm high, 19 cm wide at the top and 6 cm wide at the bottom. The size of the sheep hip bone is slightly smaller. Five to seven small holes are drilled on the bone ridge on one side of the hip bone, and five to seven small copper bells are tied with leather strips or lead wires.

At the upper left and right corners of the fan surface, there are small holes drilled respectively, and each is tied with a thin spring wound with steel wire. The end of the spring is tied with colored ribbons or decorated with colored balls. At the bottom of the lower end of the hip bone, a small hole is drilled, and an iron ring is tied, and the ring is decorated with a colorful ribbon. Two hip plates are one pair.
