It is recorded that the Kun Lu Shan tea garden was set as royal tea garden in the 7th Yongzheng of Qing Dynasty (A.D.1729). During the spring harvesting time every year, the imperial court would send troops to guard the gates and supervise the harvesting and production all the time. It was said that the production was extremely sophisticated, requiring more than 72 production steps and taking more than 36 days to complete a batch of pu erh tea. The locals would only be allowed to make teas for their own consumption or sale when the tea made for royal families was done and shipped. All such activities were kept secret, so we are unable to know exactly how such teas were made today.
Kun Lu Shan boasting about its more than 10000 mu ancient tea garden and believed to be one of the royal tea gardens during the Qing Dynasty is now praised as"the museum of tea tree". The recorded NO 3 ancient tea tree growing here, about 25 meters in height and 2.53 meters in diameter is the biggest human cultivated tea tree ever found.
