The mang tube is a single-reed gas-sounding instrument of the Miao, Dong, Shui, Yao and other ethnic groups, also known as the earth tube, the mang tube, and the reed tube.

When playing, depending on the size of the awn tube, the playing method is also different. The bass mango should be played standing up, the resonator should be placed obliquely on the ground, the player should support the body with his left hand, and play with his right hand holding the reed pipe. You can play and dance.

The sound of the mango tube is thick and strong, and the weak tone is round and soft. When the double bass mango is played, the sound is like an overwhelming sound, rolling in, and its sound can be heard from miles away.

As a bass instrument, the mangou is used in the ensemble of the reeds, and it is often combined according to the size, which is called the mango team. The large-scale mango team consists of eighteen to twenty-four mangoes, which are divided into five groups: double bass, bass, tenor, alto and treble. Each group has three to five mangoes, and their pitches differ in order Octave, from A1 to a2. The reed team composed of the mang tube team and the big and small reeds together form the reed band. The continuous long sound emitted by the mango tube makes the sound of the whole band plump and deep, with distinctive national characteristics. The mango tube is often used in the reed ensemble or as the accompaniment for the reed dance.

In the folk of the Miao and Dong nationalities, they often play the trumpet during festivals, weddings and funerals, when building a new house or during slack farming. The bass and double bass mangoes are mostly played by men, while the soprano and alto mangoes can be played by both men and women.
