Tieguanyin is not only fragrant and mellow, but also a natural and delicious drink, and its health care function is also outstanding in tea. Tieguanyin was introduced from Anxi County, Fujian Province in the eighth year of the Republic of China, and it can be divided into "Tieguanyin with red heart" and "Tieguanyin with green heart". The main producing area is Wenshan period, with thick branches and loose leaves, few buds and thick leaves, and low yield. However, the quality of wrapped tea is higher, and the production period is later than that of Qingxin oolong tea. Slightly arboreal, with oval, thick and fleshy leaves. The leaves are flat and spread out, which is suitable for planting Tieguanyin tea.
Tieguanyin is the best oolong tea. Its quality characteristics are: the tea strips are curly, fat and round, thick and even, and the color is sand green. The overall shape is like dragonfly head, spirochete and frog leg. After brewing, the soup is golden and rich as amber, with natural and rich orchid fragrance, mellow and sweet taste, and has a long history of returning to Gansu, commonly known as "rhyme". Tieguanyin tea has a high and lasting aroma, which can be described as "seven bubbles are more fragrant". "Tieguanyin" tea tree has red buds and crooked tails, delicate sex and small yield, so it is said that "delicious taste does not last long", and "Tieguanyin" tea is therefore more expensive. Pure Tieguanyin plants are shrub-type, with spreading trees and oblique branches and transverse leaves. The leaves are oval in shape, with sparse and dull marginal teeth, wavy leaves with obvious ribs, slightly rolled back, thick mesophyll, dark green and smooth leaves, slightly dull leaf base, slightly concave leaf tip, slightly inclined to the left, slightly drooping and purplish red buds, so it is called "red bud bent tail peach", which is one of the characteristics of purebred.
