Bobo, a Naxi double-reed air-sounding instrument. Naxi is also known as feeding cloth, also known as reed pipe and Bili. Popular in Lijiang Naxi Autonomous County, Yunnan Province and its adjacent areas.

Bober is composed of two parts: the pipe body and the reed whistle, with a total length of 20 cm to 24 cm. The tube body is made of bamboo, mostly made of locally grown green bamboo.

The upper and lower sections of the tube body are hollow, the tube length is 15 cm to 19 cm, the outer diameter of the tube tail is 1.2 cm, and the inner diameter is 0.8 cm. There are six or seven circular sound holes on the front of the tube body. A reed whistle is placed on the upper end of the bamboo tube. The reed whistle is a double-reed reed made of reeds after thinning and flattening. In addition, there is also a bob with a copper body, with six holes on the top, but because it is difficult to make, there are fewer users.
