Definition

Under the strictest definition, the Yungui Plateau stretches from the Red River Fault in Yunnan in the southwest to the Wuling Mountains in Hunan in the northeast. This plateau region includes most of eastern Yunnan and most of Guizhou. It is common, however, for much of the rest of Yunnan and surrounding highland areas to be referred to as part of the Yunnan–Guizhou Plateau even where there are no plateau-like characteristics.

Under the broader definition of the Yungui Plateau, the provinces would include not only Yunnan and Guizhou but also Gulin County and the southernmost extremes of Sichuan, eastern Chongqing, southwestern Hubei, western Hunan, and northwestern Guangxi.
