Taiping Xiao, a musical instrument of the Miao people. It is called Zhanbendu in Miao language, and the Miao people in Baoshan area of Yunnan call it Taiping Xiao in Chinese. Regarding the origin of the Taiping Xiao, there is such a legend circulating in the Miao area of Baoshan.

In the distant era, wars broke out among the Miao tribes, and both sides suffered heavy casualties. At this time, an old Miao artist cut down a section of bamboo and made a long flute. On the night when the two armies faced off, he played a sad "Orphan Tune", which aroused the nostalgia of the soldiers on both sides and war-weariness. Putting down the guns, the war was later ended through peaceful and friendly negotiations. Afterwards, he played another lyrical "Relaxing the Heart", and the two tribes lived in harmony from then on. Because this long flute was used to bring peace in the world, the Miao people called it the “Peace flute”. Although there is no record in historical materials, it seems that the Taiping Xiao has a long history from the fact that it is spread thousands of miles away, and the names are similar and all contain the mother tongue "Zhan".
