Yiwu, one of the tea-collecting towns on the Tea-Horse route, on one of the six historic tea mountains in Xishuangbanna, Yunnan, China.

Two women from the Yao minority group pass by the first house (a small tea factory) on the old stone road in Yiwu, the principal township on Yiwu mountain, one of Xishuangbanna's original 'Six Great Tea Mountains' north of the Mekong River. This is the beginning of one of the several tributary Tea Horse roads that converge on Simao.
