Tea culture is one of the common traits shared by all the 56 ethnic groups in China. Many Chinese people believe that a day is not perfect without a cup of tea. Either in the warm southern mountain area or on the frozen northern grassland, stuff like Gongfu tea, buttered tea and milk tea are all among the favorite drinks. Furthermore, both ancient and modern Chinese people tend to indulge in elaborating on poems, essays, dances and dramas on the tea.
