The Xibe people have a long cultural tradition, and folk songs and dances are popular. You can often hear high-pitched and unrestrained hunting songs, cheerful wedding songs, field songs of productive labor and pastoral songs full of grassland flavor. When night falls on the earth, young men and women will sing duets of love songs from a distance, with beautiful tunes and beautiful words, sometimes replaced by melodious and euphemistic reed flutes.

Among the Xibe people, people often play the reed flute to entertain themselves while grazing in the wild or resting during field labor. At night, it is an inseparable close friend of young people. The young man uses the reed flute to convey friendship and love to the girl. Playing it in the silent night, the beautiful flute sound spreads far and far.
