The drum body is flat and small, and the drum surface is octagonal. The drum frame is made of ebony, rosewood, rosewood and bone chips. Specifications vary. Usually, the drum head angle is 16.5 cm ~ 19 cm, and the drum frame is 4.8 cm ~ 5.5 cm high. One side is covered with python skin, donkey skin or horse skin, preferably small scale python skin. The edges are also inlaid with bone pieces as decoration. There is a petal-shaped through hole of begonia in the middle of the seven frames of the drum, and a pair of copper cymbals are pierced in the middle with copper nails. On the other side of the shelf, a small copper ring is installed, decorated with goose yellow or big red silk knots, and two yellow or big red silk ears hang down, indicating that there are two ears in the grain, symbolizing a bumper harvest. Small and exquisite in appearance and fine in production, it can not only be played as a musical instrument, but also has high artistic appreciation value.

When playing, put the drum surface vertically, put the thumb, index finger and middle finger of the left hand into the drum frame, hold the drum with the ring finger and little finger, and tap the drum surface with each finger of the right hand to pronounce. The tone is crisp and beautiful. There are many ways to play. In the past, there were "ten drumming methods" and "five drumming methods". Now there are sitting, beating, cushion, wheel, rubbing, knocking, beating and winnowing respectively. There is a folk saying: "Hold the moon without bias. Steady and avoid shrugging. Shake your wrist and shake your arm, and the cushion wheel should be twisted. " In the singing method, only the sitting method is used, the yang (shaking) method is used in the subterfuge part of the tune, and the techniques such as playing, pad, wheel, rubbing and knocking are used in the prelude and interlude part of the fork and melody. You can also tap the back of the drum skin with your left thumb and forefinger. In particular, the sound produced by the combination of beating the drum surface and shaking the drum body is more distinctive.
