In the production process, the chlorophyll contained in tea leaves is destroyed, so that the fermentation degree varies from 20% to 70%, which is a semi-fermented tea, such as Tieguanyin, Dahongpao and Wuyi Rock Tea. The production process mainly includes fresh leaves, withering (sun-drying, air-drying), green-making (shaking), green-fixing, kneading, baking with rough fire, kneading, full fire, drying and so on.
