Dahongpao tea is not black tea, but oolong tea with excellent quality. Dahongpao tea with the best quality was picked around the long summer, and black tea was picked around Qingming. Dahongpao is produced in Wuyishan, Fujian, and its production technology combines the techniques of green tea and black tea. Dahongpao's tea has a blue fragrance, and the brewed tea soup is bright orange with a unique blue fragrance. "Dahongpao" is a fir tea tree, which grows on the Gaoyan Cliff in Kowloon, Wuyishan. The "Dahongpao" stone carving made by the monks of Tianxin Temple in 1927 is still preserved on the rock wall, where the sunshine is short, the light is reflected more, the temperature difference between day and night is large, and Koizumi infiltrates and drips on the top of the rock all the year round. This special natural environment has created the special quality of Dahongpao. At present, there are 6 kinds of tea trees in Dahongpao, all of which are shrubs with thick leaves and reddish buds. When the sun shines on tea trees and rocks, the rock light is reflected and the red color is very bright.
