Spread the picked fresh leaves according to a certain thickness and dry them to make the fresh leaves appear wilting. During the withering process, the fresh leaves undergo a series of changes: the water decreases, the leaves become soft and brittle, which is easy to be twisted into strips; the activity of the enzymes contained in the leaves increases, which promotes starch, protein, insoluble pro-pectin and other fresh leaves The components are decomposed and transformed to produce glucose, amino acids, soluble pectin and other effective substances that are beneficial to the quality of tea. Polyphenols are also oxidized to varying degrees.
