Tian (天 Pinyin TiÄn) is the Chinese character for heaven or sky. As such, it holds an important place in many Chinese belief systems such as Mohism, Taoism and Confucianism. The ideograph itself suggests the expanse of sky above the earth on which humans dwell, thereby giving rise to the term "Tianxia" (天下 All under heaven); the phrase is often used to describe the earthly domicile in Chinese literature.
