Tea is one of the greatest cultural treasures of Chinese civilization. Tea was historically discovered by the legendary emperor, Shennong, who believed that water was safe to drink only by first boiling it. One day he noticed some leaves had fallen into his boiling water. The ever curious monarch took a sip of the brew and was pleasantly surprised by its flavor and its restorative properties. Tea remained in Chinese hands for centuries, before foreign explorers brought this to an enthusiastic public in Europe and other places. Tea drinking then became a standard feature of the Chinese culture. Regions famous for Chinese tea in the south have produced much of the world's tea. China for centuries has been acting as the first nation of tea because of its outstanding products. Today, Chinese tea must compete against foreign teas from many other places in the world. China has an advantage in this, however, because of her long history and the quality of her teas. Rituals have even appeared in the preparing and drinking of tea. This tea culture places emphasis on the taste and color of the tea as well as on the presentation of the tea set. Tea has become more than a mere drink. Rather, it is a symbol of the Chinese people and culture.

茶是中华文明最宝贵的文化财富之一。历史上，茶是带有传奇色彩的帝王神农发现的，他认为水只有先烧开之后饮用才是安全的。一天，他发现一些叶子掉进了他烧开的水中。一向好奇的君王尝了一口，他为其芳香和恢复体力的功效而惊奇、兴奋。早在外国探险家把茶带给欧洲和其他地方热情的民众之前，茶已在中国留传了几个世纪。饮茶在当时成为中国文化的标准特征。因中国茶叶而闻名的中国南部生产出了世界上大部分的茶叶。中国几个世纪以来因其优质的茶产品一直扮演着世界第一茶叶大国的角色。现在中国的茶叶必须和来自世界其他地区的外国茶叶竞争。但是中国由于其悠久的历史和茶叶的质量，在这方面具有较强的优势。在泡茶和品茶的过程中还出现了茶道。这种茶文化注重茶的味与色，以及茶具的摆放。茶已经不单单是一种饮品，它是中国人和中国文化的象征。
