At the beginning of 1985, a famous tea creation group was established with the participation of Zhang and Fu, and trial production was carried out in an all-round way. Picking pigeon pit seeds and buds and leaves of Fuding Dabai tea as raw materials, there are three grades of picking standards: super-strong buds, 1 grade, one bud and one leaf, grade 2, one bud and one leaf and a small amount of one bud and two leaves. Fresh leaves are spread out for about 4 hours after entering the factory. After the technological processes such as deactivating enzymes, twisting, shaping, sieving and cooling, and hot pot drying, the dried tea is fried with 10 techniques such as pulling, rolling, grasping, shaking, throwing, kneading, grinding, spitting and dissolving. The shape is flat, the color is green, and it looks like cypress. The essence is elegant and lasting, the soup is clear and bright, the taste is mellow and fresh, and the leaves are yellow, green, bright and tender.
