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.

3. Fixing: Use a green-fried machine to destroy the tea enzymes in the tea to prevent the leaves from turning red, so that the green taste in the tea fades and the tea fragrance emerges.
