China's Tusi Chieftain Sites apply for inclusion on the 2015 World Heritage List this March. The representative sites consist of Yongshun Tusi Site in China's central Hunan Province, Tangya Tusi Site in Hubei Province and Hailongtun Site in Guizhou Province. The Tusi Sites are unique to the Tusi system, a self-ruled political system adopted by feudal Chinese emperors to manage ethnic minority regions by allowing local tribal leaders to rule their tribes on the basis of both the empire's law and local customs.
