Nannuoshan ancient tea is mainly distributed in Hani villages such as Banpo Old Village, Shitou Old Village, Bama, Shitou New Village, Duoyi Village, Guniang Village, Yakou Old Village, Xiangyang Village, Shuihe Village and Bala Village.
It is impossible to verify the earliest time when Nannuoshan began to grow tea, but it is certain that the ancestors of Bulang nationality still planted this kind of tea until Nanzhao period; Later, the Bulang people moved away from Nannuo Mountain, and the tea mountain left behind was inherited by Aihua people. According to the father-son name system of the local Ewa people, it can be inferred that they have lived in Nannuo Mountain for 57 to 58 generations, which lasted about 1 100 years.
A long time ago, the forest around Banpo Laozhai was dense and the traffic was very inconvenient. Tea can only be transported by caravan. Due to the excellent quality of local tea, a large number of caravans will enter the village and carry tea to Simao, Menghai and Mengla every year after October of the lunar calendar, and some large caravans will directly carry tea to many countries in Southeast Asia.
The old man in Nannuoshan said: "Although Pu 'er has tea locally, its taste is far less than that of Dashu tea in Nannuoshan. Pu 'er people rely on the tea from Nannuo Chashan to produce high-quality Pu 'er tea, which enjoys a good reputation at home and abroad. Of course, the prosperity of Pu 'er tea has also driven the prosperity of Nannuo Mountain. "
