People of Oroqen, Ewenki, Daur and other nationalities live together in the northeastern part of Inner Mongolia Autonomous Region and the virgin forest areas of the Greater and Lesser Xing'an Mountains in Heilongjiang Province. They make a living by hunting. Roe deer, also known as roe deer, is a kind of deer, with a body length of more than one meter and a short tail, no more than three centimeters. The male roe deer has horns and often inhabits hillsides or dense forests.

Oroqen and other ethnic hunters created a small hunting musical instrument - the roe deer whistle. Every July and August in summer, when the roe deer juvenile hair is not retreating, the hunters hide in the jungle and blow the roe deer whistle that simulates the roe deer cry. The female roe deer who went out for food will quickly run back, and the wolves and black bears in the deep forest will also search for the sound and come to prey on the roe deer cubs. The hunters work together to kill roe deer, and sometimes they can also hunt down wolves and bears, which can be said to be a good harvest.

Today, roe deer whistle is not only owned by young men of the Oroqen ethnic group, but also loved by unmarried women. From spring to summer, from summer to autumn, the girls often blow the birch bark whistle in the mountains and forests and beside the creek. This ancient folk musical instrument that has been passed down from generation to generation has now become the "matchmaker" for young men and women to fall in love.
