Because the Dong nationality has a long history in the Chinese nation, it originated from the ancient Baiyue nationality and developed from a branch of Xi 'ou in Qin and Han Dynasties, while the Miao nationality happened in the legend of Yanhuang five or six thousand years ago, so the Dong nationality has a long history.

Dong is a minority in China, and its national language is Dong, which belongs to the Dong Shui branch of the Zhuang Dong language family of Sino-Tibetan language family. Miao ancestors first lived in the middle and lower reaches of the Yellow River, and their ancestors were Chiyou.
