Man Sa Shan 漫撒山: located in the east of Meng La County, bordering Laos and is one of the six famous tea mountains. The local climate is mountainous, monsoon and subtropical, the plantations lie at altitudes between 820-2000m.n.m., The relative humidity is about 80%.
Yiwu 易武: The wider Yiwu region includes four other counties: Man Sa, Ma Hei, Yi Tian and Man Luo. In ancient times, people from the Bulang ethnic group were the first to cultivate and grow tea trees here. By the end of the Qing Dynasty (Qing, 1890-1912), there were already a large number of Han merchants in the Yiwu area who began growing tea there. They set up businesses engaged in the tea trade here and established a collection point for local teas among the “six famous tea mountains” (Gu Liu Da Cha Shan – Six Famous Tea Mountains, Attention! Do not confuse the brand of pu-erhas of the common quality of the same name!). In practice, the Yiwu region also includes another tea mountain – Man Sa (which does not fall geographically under Yiwu). Today, in the vast Yiwu area, tea is grown on approximately 2505 acres (15,000mu, 10M m2) which produces about 600 tons per year. The gardens are at altitudes of 820-2000m.n.m. The annual total precipitation is between 1000-1800mm and there is 1600-2000 hours of sunshine per year with 80% relative humidity. The weather is warm and humid all year round without frost.
