A musical instrument made of bamboo tubes by the Jino people. The shape is very similar to the high-pitched mango tube of the Dong nationality, and it is mostly made of a section of moso bamboo. Each bamboo tube is about 30 cm high and about 6 cm in diameter. The upper end is open and trimmed into an inclined plane, the bottom of the lower end is left with a bamboo joint, and a vertical gap about 1 cm wide is opened just below the inclined plane of the bamboo tube mouth. Bouchons are mostly used in warm celebrations. When hunting big beasts, they usually hit the big Bun with their mouths up, and when they hunt small beasts, they hit the little Buns with their mouths down. These bamboo slips are struck with hardwood sticks, and generally do not have a fixed pitch. The performance is usually performed in groups, and at least two people are required to strike together.

Bugu has been circulated among the Jinuo people for a long time, and has developed into groups of bamboo tubes with fixed pitch. Generally, it consists of 4 to 7 pieces, and a group of 7 is the most popular. The bamboo tubes in groups are 20 to 40 cm high and 5 to 7 cm in diameter. Played by a person sitting on the ground. The sounds of a group of 7 Bugu are listed as a pentatonic scale, with a range of (g~a1). The sound is crisp and pleasant. When welcoming the return of the hunting party, people often sing rough songs to the accompaniment of the bungu to celebrate. In recent years, Bouchou has been used for stage performances. The performer sings a group of budu with the baton, and sings together with several other singers who play budu without a fixed pitch. Groups of bungu sang the simplified melody along with the singing tune, the sound was rich, the atmosphere was warm, and it was full of strong Jino style.
In October 1980, in the National Ethnic Minority Art Festival, the Jinuo Bailazhi placed bamboo tubes of different sizes on the shelf to make five-tone bamboo tubes for solo performances. The players who hold a single bamboo tube with no fixed pitch sing the "Hunting Minor" in concert with each other, which is vivid and unique, simple and rough, with a warm atmosphere and rich Jino style.
