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

75-year old Li Yingchang, a key figure in the tea business of Yiwu, drinks tea produced by his own household factory, served by his son-in-law Huang Dingfu. Since 1949 this courtyard house, actually 'no. 1' on the Tea Horse Road that begins here, has processed tea from Yiwu Mountain, one of the original 'Six Great Tea Mountains', north of the Mekong River.
