Tea connoisseurs will not want to miss out on the exquisite pu-erh teas of Bai Ying Shan 白莺山, one of the branches of the Wu Liang Shan 无量山 in Yunnan Lincang Region in Southwest China, adjacent to the Lan Cang River. It is the birthplace of the Yunnan Big Leaf Tea, its oldest tree being an impressive three thousand years of age. The tea gardens in Bai Ying Shan village, some even up to a millennium in age, boast tea trees of remarkable size. Situated atop the mountain, facing Northeast, the terrain enjoys ample sunlight all day and cool night temperatures. Additionally, the moisture from the Lan Cang River ascends to form clouds and mist, conditions that contribute to the outstanding quality of its tea.
