The deer flute is a musical instrument of the Oroqen, Ewenki, Daur and other ethnic groups, also known as deer whistle.

The Oroqen, Ewenki, Daur and other ethnic groups are ethnic minorities living in the northeastern Inner Mongolia Autonomous Region and the Daur and Xiaoxing'anling virgin forest areas of Heilongjiang Province. They make a living by hunting, especially the Oroqen ethnic group. He learned to hunt with his father and brother since he was a child, and people praised the hunter as a "smart hunter". For a long time, they have accumulated rich hunting experience and created a unique hunting instrument - deer flute.

According to "Heilongjiang Wai Ji": "The deer who whistles deer in Butha today are called deer. Their whistle is made of wood... Neng Xiaoyou's exhausted voice" The golden autumn season is the mating period of deer animals. In the open forest area, the females are chasing each other, which is a good time for hunting. The hunters are sucking the deer flute and blowing the flute in the forest, simulating the calls of the male deer such as red deer, moose (e) and sika deer. The deer will hear the sound, and the male deer will respond to the sound of the flute, and come to compete for the doe. The wise hunter will shoot the doe first, and then the infatuated male deer when the herd enters the ambush circle. Returning triumphantly loaded with prey.
