Lie is a folk musical instrument that is deeply loved by the Lahu people. Men and women, old and young, often carry it with them. They are not restricted by time and place. Whether they are working in the mountains or returning to the village after work, they can play while walking when they are happy.

Young men and women are more partial to Liedu. In the quiet night of the cottage, whenever the young man is looking for a girl to have a romantic relationship, he will go to the girl's room and blow the Liedu, and the girl will come out to meet.

Well-known pieces include "Working Tunes", "Walking Tunes", "Chasing Little Birds" and "Chuan Girls Tuning". Famous folk musicians include Yang Laowu, Mengman District, Menghai County.
