中南地区
Tianzi Mountain () is a mountain in Zhangjiajie in the Hunan Province of China, close to the Suoxi Valley in South Central China. Before the Ming Dynasty, Tianzi Mountain was known as "Qingyan Mountain" because of its green stones. The mountain is named after the early Ming dynasty's farmer Xiang Dakun of the Tujia ethnic group, who led a successful local farmers' revolt and called himself "Xiang Wang Tianzi", meaning "son of Heaven" and is the traditional epithet of the Chinese emperor.
