1. Withering: It is divided into two types: sunlight withering and indoor withering. Sunlight withering is also known as sun-dried green, which allows fresh leaves to emit some water, and moderately transforms the contents of the leaves to reach a suitable degree of fermentation; indoor withering, also known as cool green, allows fresh leaves to wither naturally indoors, and is also a common type of oolong tea withering method.

2. Shaking: is the key to making oolong tea (green tea) green. After the withered tea leaves are shaken for 4 to 5 times, the fresh leaves undergo a series of biochemical changes, forming the unique "green leaf and red border" characteristics of the oolong tea base and the unique aroma of oolong tea.
