The Zhuang ('dʒwæŋ,_'dʒwɒŋ; ; Bouxcuengh poːu˦˨ ɕeŋ˧; Sawndip: 佈獞) are a Tai-speaking ethnic group who mostly live in the Guangxi Zhuang Autonomous Region in Southern China. Some also live in the Yunnan, Guangdong, Guizhou, and Hunan provinces. They form one of the 56 ethnic groups officially recognized by the People's Republic of China. With the Bouyei, Nùng, Tày, and other Northern Tai speakers, they are sometimes known as the Rau or Rao people. Their population, estimated at 18 million people, makes them the largest minority in China.
The Chinese character used for the Zhuang people has changed several times. Their autonym, "Cuengh" in Standard Zhuang, was originally written with the graphic pejorative Zhuàng, 獞 (or tóng, referring to a variety of wild dog). Chinese characters typically combine a semantic element or radical and a phonetic element. John DeFrancis recorded Zhuàng was previously Tóng, , with "dog radical" and tóng, phonetic, a slur, but also describes how the People's Republic of China eventually removed it. In 1949, after the Chinese civil war, the logograph 獞 was officially replaced with a different graphic pejorative, (Zhuàng or tóng, meaning "child; boy servant"), with the "human radical" with the same phonetic. Later 僮 was changed to a different character Zhuàng, (meaning "strong; robust").
The Zhuang, Nùng, and Tày people are a cluster of Tai peoples with very similar customs and dress known as the Rau peoples. In China, the Zhuang are today the largest non-Han Chinese minority with around 14.5 million population in Guangxi Province alone. In Vietnam, as of 1999, there were 933,653 Nùng people and 1,574,822 Tày people. Recently the Tày and Nùng have been referred to as a combined Tày-Nùng minority. However these ethnonyms are a recent phenomenon and did not exist until the modern age. According to Keith Taylor, the Vietnamese terms were "categories of French colonial knowledge" used to differentiate highlanders from lowlanders. The ethnic Zhuang was a product of the "ethnic identification project" pursued in 1950s China.
