Kham
Kham (Wyl. khams), often translated as Eastern Tibet, is one of the three main provinces of Tibet (the others being Ü-Tsang and Amdo). Traditionally, it is said to cover the area known as the 'four rivers and six ranges' (Tib. chushi gangdruk). The 'four rivers' are the Manchu, Dzachu, Drichu, and Ngulchu. The 'six ranges' are the Zalmo Range, Tsawa Range, Markham Range (smar khams), Menyag-rab Range, Pobor Range, and Mardza Range.
