Tian

Tian (Chinese: 天, Tiān, T'ien, "sky, heavens") is one of the oldest Chinese terms for the cosmos and a key concept in Chinese mythology, philosophy, and religion. During the Shang Dynasty (17–11th centuries BCE), the Chinese called their supreme god Shangdi (上帝, "Lord on High") or Di ("Lord"); during the Zhou Dynasty, Tian became synonymous with this figure. Heaven worship was, before the 20th century, an orthodox state religion of China.
