Ding Dong is composed of a wooden pole and a wooden frame. The wooden pole is the pronunciation body, and it is mostly made of mahogany or other hard wood. The pole is 200 cm to 240 cm in length and 10 cm to 12 cm in diameter. 

Floral patterned tripod on wooden frame. In Hainan folk, the Li family often uses the local "Chai Jishen" (called kenaf tree in Hainanese) wood to make.

Each wooden bar can emit two notes in the relationship of fifths, the previous one is c1, g1, the next one is a, e1, and the upper and lower two are the harmonic intervals of the minor third. When the pitch is inaccurate, in addition to using a knife to correct the wooden pole, the ropes at both ends of the hanging wooden pole can also be adjusted. In Li villages, in addition to two wooden poles, there are three, four or five ding dongs.
