Oolong tea evolved from the tribute tea dragon group and the phoenix cake in the Song Dynasty, and was created around 1725 during the Qing Dynasty and Yongzheng period. At that time, oolong tea was also called green tea. In historical documents, we can see that oolong tea belongs to green tea, and there are also legends about oolong tea:
According to Tea in Fujian and Tea Folklore in Fujian, during the Yongzheng period of the Qing Dynasty, there was a tea farmer who was an expert hunter in Nanyan Village, Xiping Township, Anxi County, Fujian Province. Because of his dark and strong appearance, the villagers called him "Oolong". One spring, Oolong hung a tea basket around his waist and picked green tea in the mountains. By noon, in order to catch up with a mountain water deer and delay time, he had completely forgotten about coming back to process green tea.
The next morning, the whole family was busy frying the "green tea" collected yesterday. I didn't expect that the fresh leaves that had been left overnight had been edged with red edges and gave off a fragrance. At that time, when the tea was made by the steps of processing green tea, the taste was particularly fragrant. After pondering and repeated experiments, after the processes of withering, shaking, semi-fermentation, baking, etc., a new oolong tea with excellent quality was finally made, which was obtained by letting the green tea be placed there for semi-fermentation.
