Also known as eagle flute or eagle bone flute, Tibetan, Tajik, Kirgiz edge air-sounding musical instruments, called Dangja in Tibetan.

It is a self-entertainment wind instrument favored by Tibetan youths. It is mostly played for self-entertainment during grazing or field work in summer.

Hemudu culture (about 7000 years ago). In 1973, there were dozens of bone flutes unearthed at the Hemudu site in Yuyao, Zhejiang Province, among which two pieces (7.1 cm in length at the top and 5.31 cm in length at the bottom) were collected by the Zhejiang Provincial Museum. Made from the middle of the limb bones of birds. The tube has one to three round holes, and some have a limb bone inserted into the inner cavity, which is similar to the bamboo whistle of modern children's musical instruments. Some bone flutes can still play simple tones. They are the distant ancestors of the flute and flute instruments in later generations.
