White tea can be divided into four products: Baihao Yinzhen, Baipeony, Shoumei and Gongmei [20] due to different varieties of tea trees and requirements for raw materials.

As the raw materials of fresh leaves are all tea buds, and after the finished tea is made, the shape is like a needle, the pekoe is densely covered, and the color is as white as silver, so it is named pekoe silver needle.

White tea has a long history. According to historical records, during the Eastern Han Dynasty, a young man named Yin Zhen, with a self-made tea made in his hometown, paid a visit to Xu Shen, a famous Confucian master. When the disciples made difficulties, he ate tea under his eaves. For a moment, Xu Shen's entire residence was filled with strong tea fragrance. Xu Shen strolled to trace the origin, and then invited Yin Zhen into the study to brew his "tea cup". But he saw its beautiful shape. The white leaf bottom was like a silver needle dropping a pot. The soup was green and bright. The taste was fresh and mellow. Occasionally, the taste was mild and bitter.
