The settlement of Qianjiazhai is located on Ailao Mountain, surrounded by moist evergreen broadleaf forests that spread across an ecologically pristine protected area at an altitude above 2000 meters above sea level. Here, in the Zhen Yuan Nature Reserve, lies the largest natural zone of wild tea tree growth in the world. Among them grows the oldest known tea tree, which has been thriving for 2700 years.

Master Xiang selected ancient tea trees aged around 300 years, a typical large-leaf Da Ye Zhong variety for this area, growing at an altitude of 2500 meters above sea level, for this sheng puerh. As always, she used exclusively manual techniques at every stage of production, revealing the full essence of the unique local terroir.
