South West China, the exotic area, home to many minority ethnic groups. Like other parts of West China, it is far less prosperous than the eastern and southern coastal regions.
Much of the terrain is quite mountainous. Tibet and Yunnan have many very high mountains; the world's highest (Mount Everest) is on the Tibet/Nepalese border. Guizhou and Guangxi have smaller mountains, including the karst limestone terrain, with fantastically gum drop shaped hills, terraced rice fields, and many caves.
