The Dai Ding 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.

As early as the 29th year of Hongwu in the Ming Dynasty (1936 AD), Li Sicong and Qian Guxun of the Ming Dynasty were dispatched by the imperial court to go to Baiyi (today's Dai area in Dehong) for inspection. They use instruments similar to Huqin, which are called "Huqin and the like" in their "Bai Yi Zhuan". This is the Xi Ding of the Dai people today. According to this, Dai Ding has a history of 600 years.

During the Han and Jin Dynasties, Dai Ding was historically known as "Dian Yue". In the Yuan and Ming Dynasties, it was called "Bai Yi". In the middle of the Ming Dynasty, the Dai people who were good at singing and dancing came to the mainland of the motherland to perform ethnic songs and dances. "Yunnan Tongzhi Baiyi Biography" contains: "The music in the car is made by the people in the car, using sheepskin as a long drum of three to five (chi), beat it with hands, and use bronze cymbals, bronze drums, and clapboards in between, and the Chinese The joy of (inland) is no different. When feasting in the countryside, it is fun to beat drums, play reeds, and dance (shield) boards."

Regarding the Ding, there is a legend among the Dai people in the southwestern border of the motherland: in ancient Ruili, there was a heroic and adept commander of the Dai people, Zhao Wuding. On one occasion, he used a beautiful and beautiful Ding to command the elephant herd, defeated the invading enemy, and was loved by the people.

Ding is a musical instrument often played by young Dai people when they are in love, and is known as the "love instrument" in the Dai people.
