Daiding (西玎) (pinyin: dǎi dīng) Daiding is a plucked stringed musical instrument of the Dai people. Also known as Xi Ding or Ding Xi. "Ding" in the Dai language means to play the qin, which is the general name of the stringed instruments played by the Dai people. It is popular in Dehong Dai and Jingpo Autonomous Prefecture, Simao, Lincang and other areas in Yunnan Province.

The shape is similar to erhu or banhu, with a total length of 75 cm to 85 cm. The qin barrel is cylindrical and is mostly made of locally grown dragon bamboo or coconut shells, but also gourds, wood or pottery. The outer skin of Dalong bamboo is removed, and the appearance is cut into a cylindrical or oblate shape, which is similar to coconut shells.
