Tieguanyin is a kind of oolong tea, which originated in Anxi County, Fujian Province. Tieguanyin is a semi-fermented tea between green tea and black tea, and is considered as one of the top ten famous teas in China. Tieguanyin was originally the name of tea varieties. Because it is suitable for making oolong tea, its oolong tea product is also called Tieguanyin. The so-called Tieguanyin tea is oolong tea made of Tieguanyin variety tea tree, and there is another saying that the name "Tieguanyin" was given by Emperor Qianlong. In Taiwan Province Province, Tieguanyin Chaze refers to oolong tea made by a specific method of Tieguanyin tea, so the raw material of Tieguanyin tea in Taiwan Province Province may or may not be the bud leaves of Tieguanyin tea tree.

Characteristics of tea: green, oblique branches, open crown, oval leaves, thick and crisp mesophyll and dark green leaves. The teeth on the leaf margin are sparse and blunt, the leaf surface is wavy, slightly rolled back, the tip of the leaf is slightly concave to the left, slightly drooping, and the bud is purple-red, so it is called "red bud crooked tail peach".
