Bage Diudong, a Miao fringe musical instrument. Because it is made of bark, the Han people call it the bark tube. Popular in Guangxi Zhuang Autonomous Region Longlin, Xilin, Tianlin, Napo and other parts of western Guangxi.

In the mountainous area of Guixi, surrounded by fog and green peaks, there are industrious and simple people of all ethnic groups such as Zhuang and Miao. With their diligence and wisdom, they have created rich material wealth and created a variety of national culture and art. In spring and summer, the mountains are full of green, and everything is full of vitality. At this time, no matter whether you step into the Zhuang Township with green water and mountains, or climb the Miao Village with the sea of fog and clouds, you will hear the beautiful sound like birdsong and the crisp and clear sound of the flute reverberating in the mountains. It, together with the bursts of Lin Tao and the ding dong mountain spring, form a symphony of nature, adding a lot of poetry and picturesqueness to the mountain village. But it was not some symphony orchestra playing, nor singing birds singing, but just a beautiful sound from a very simple earthen pipe. That is the folk musical instrument favored by the Zhuang and Miao people in western Guangxi - the bark pull pipe.

The tone of Bagad Diutong is crisp and high-pitched, similar to the whistle sound, and is deeply loved by young people and children of the Miao nationality. Whenever going up to the mountains for grazing or taking a break in labor, one can easily make a bagodon, which can be played for self-entertainment and to disperse fatigue. Solo pieces include "Miao Shan Huan" and so on.
