For the pu-erh tea lovers, Bai Ying Shan is definitely the one which can not be missed. I think the best vintage pu-erh tea I ever had is a 2007 crop Bai Ying Shan. It is really wondeful for the sweetness and rich strong taste it gave. 

Bai Ying Shan 白莺山 is one of the branch mountains of Wu Liang Shan 无量山 in Southwest Yunnan Lincang Region, and near Lan Cang River. Though it is still not yet very famous among the many tea mountains of Yunnan,  Bai Ying Shan is the origin of the Yunnan old big tea trees as study indicates. Here there is the oldest tea tree more than 3,000 years old, and the biological character of the tea seed of Bai Ying Shan old tree proves here is the birthplace of the Yunnan Big Leaf Tea. The tea species growing here according to the farmers include Ben Shan Cha 本山茶, Hei Tiao Cha 黑条茶, Er Ga Zi Cha 二嘎子茶，Meng Ku Zhong 勐库种, Bai Ya Cha 白芽茶，Liu Ye Cha 柳叶茶, He Zhuang Cha 贺庄茶 and Teng Zi Cha 藤子茶.

The tea trees grow in the Bai Ying Shan Village. Here the trees are not close to each other. But many of them are very big and thousand years old. 

Bai Ying Shan village is on the peak of the mountain and faces Northeast. This location makes the land entirley exposed to the Sunlight all the day. And at night, the temperature lowers a lot.  The moisture from the Lancang River goes up to the mountain and forms cloud anf mist. This kind of weather is very good for the quality of tea.
