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.

Bob is the ancient Bili. According to legend, in 1253 AD, when Kublai Khan, the ancestor of the Yuan Dynasty, marched south to Dali, Yunnan, Bobo was brought to Lijiang by a Mongolian band accompanying the army, and it has been passed down among the people to this day.

This instrument was called the head pipe in the Song Dynasty, and it was the main wind instrument in Jiaofang Dale and drum music. "The History of the Yuan Dynasty, Records of Rites and Music" states: "The instrument of Yan music has a head tube, with bamboo as the tube, rolled reed leaves as the head, and seven orifices." The shape of the Naxi Bobo today is roughly consistent with the head tube recorded in the Yuan history.
