About ten years ago, I went to Shangri la county, Diqingzhou, Yunnan Province, China. The place borders Tibet with an altitude of 3500 to 4000, similar to Lhasa. Where Tibetan lives and is also a Tibetan-inhabited area. I do see many yaks there, which gets around on hills. Yaks are smaller than normal oxen and Buffalo, but they have long fur and look very interesting.
