Tea culture is the crystallization of Chinese people’s tradition and custom of drinking tea combined with the development of their technique of processing tea leaves to produce the final product. Tea is a shrub ( Thea sinensis ) which has fragrant white flowers and evergreen leaves. The dried leaves of this plant, plucked in various stages of growth and prepared by various processes, are used to make a hot beverage. If the leaves are fully fermented or oxidized before drying, the final product is called black tea because it is dark in color. “Black tea” is the term used by English-speaking people. In the Chinese language it is referred to as “red tea” in contrast to “green tea”.
