In the Miao area of southeastern Guizhou, the night flute is popular and popular among people. Especially young men have special feelings for it. Over the years, playing the night flute has become a signal of love between young men and women of the Miao ethnic group.

In their spare time or during the slack of farming, whenever night falls and the breeze blows, the Miao boys will come to the neighboring villages in groups of three or five, play the night flute gently, and invite the girls to come out and sing. In the initial stage of a relationship, two pairs of young men and women are usually active together, so in addition to solo performances, Yexiao often plays in unison with two pieces of the same pitch. The songs played are mostly love songs with lyrics, such as "You Fang Diao", "The Moon Has Come Out" and "You Are Sleeping Girl".

In some Miao villages in Guizhou, every night when the bright moon is in the sky and all sounds are silent, the Miao young man will bring his own night flute and come near the beloved girl's house or in front of the window, and use the flute to tell his love for his sweetheart. . The simple and euphemistic tune drifted in the night sky, as touching as fairy music. When the girl heard the boy's "invitation song", she would immediately go out to meet him. They both sat beside the bushes or on the lawn, the young man continued to play the night flute, and the girl played the bamboo reed. Popular in the fruit forests in the Rongshui area of northern Guangxi, the Miao people mostly play it when they go up the mountain to produce, rush along the slopes or sing to accompaniment, and can play it day or night throughout the year.
