The different types of Chinese tea include black, white, green, yellow, oolong, and dark tea. Chinese tea is often classified into several different categories according to the species of plant from which it is sourced, the region in which it is grown, and the method of production used. Some of these types are green tea, oolong tea, black tea, scented tea, white tea, and compressed tea. There are four major tea plantation regions: Jiangbei, Jiangnan, Huanan and the southwestern region. Well known types of green tea include Longjing, Huangshan, Mao Feng, Bilochun, Putuofeng Cha, and Liu'an Guapian. China is the world's largest exporter of green tea.
