The Dong, a Kam–Sui people of southern China, are one of the 56 ethnic groups officially recognized by the People's Republic of China. They are famed for their native-bred Kam Sweet Rice, carpentry skills, and unique architecture, in particular a form of covered bridge known as the "wind and rain bridge". The Dong people live mostly in eastern Guizhou, western Hunan, and northern Guangxi in China. Small pockets of Dong speakers are also found in Tuyên Quang Province, northern Vietnam.
The Dong are thought to be the modern-day descendants of the ancient Liáo peoples who occupied much of southern China. Dong legends generally maintain that the ancestors of the Dong migrated from the east.
Today, many Dong are assimilating into mainstream Chinese society as rural Dongs move into urban areas, resulting in intermarriage with the Han Chinese and the loss of the Dong language. However, various attempts to preserve Dong culture and language have been very successful, and improving living conditions in rural Guizhou may entice local Dong villagers to stay rather than move to major urban areas.
The Dong or Kam People are internationally renowned for their polyphonic choir singing called Kgal Laox in their own language, which can be literally translated as Kam Grand Choir in English. The Kam Grand Choir has been listed by the UNESCO as a world-class intangible cultural heritage since 2009.
