This study presents Pu'er tea's range while shedding light on its identity and classifications, which are directly related to Yunnan province's growth. The previous scholarship had widely neglected this topic and failed to examine the diversity of Pu'er tea. However, for this research work, there are four primary objectives: identifying and highlighting ancient and king Pu'er teas; assessing the economic standing of the Bulang Buddhist community; differentiating between these two varieties of Pu'er tea; and exploring the historical context of Chinese tea culture. The study revealed four main findings. The first suggests that tea traders promoted the phrase "Pu'er tea" to integrate and assess all Pu'er area tea varieties in order to enhance sales. The fourth finding, based on Chinese tea history, demonstrates the significance of ancient and King Pu'er teas for the Bulang Buddhist community. The third finding indicates a total of eight varieties of Pu'er tea. This study employs a mixed-methods approach, integrating both qualitative and quantitative techniques. The author conducted in-depth interviews with twenty two study participants and carried out fieldwork in the Laoman'e hamlet in Xishuangbanna, in the Chinese province of Yunnan. This study is significant for the Bulang Buddhist ethnic group of Laoman village, who rely mostly on the ancient and king pu'er tea sale in the mountain region of Xishuangbanna, Yunnan Province, China.
