China is second only to India in the production of tea. It manufactures green, oolong and black teas. In addition to the many provinces which produce recognizably named teas such as Keemun, Yunnan, and Fujian, there are hundreds and hundreds of districts (called hsiens) within these provinces, each producing teas with names having nothing to do with that province. China teas are often classified by the season of picking, by personal name, or after a mountain, lake or other landmark. China black teas are grown and produced mainly in the southern provinces, and yield a cup that is fragrant and sweet.
