Fuxi or Fu Hsi (伏羲 ~ 伏犧 ~ 伏戲) is a culture hero in Chinese mythology, credited along with his sister and wife Nüwa with creating humanity and the invention of music, hunting, fishing, domestication, and cooking as well as the Cangjie system of writing Chinese characters around 2000 BC. Fuxi was counted as the first mythical emperor of China, "a divine being with a serpent’s body" who was miraculously born, a Taoist deity, and/or a member of the Three Sovereigns at the beginning of the Chinese dynastic period. Some representations show him as a human with snake-like characteristics, "a leaf-wreathed head growing out of a mountain", "or as a man clothed with animal skins." He is also known as Bao Xi(包牺) and Mi Xi(宓羲). Pangu was said to be the creation god in Chinese mythology. He was a giant sleeping within an egg of chaos. As he awoke, he stood up and divided the sky and the earth. Pangu then died after standing up, and his body turned into rivers, mountains, plants, animals, and everything else in the world, among which is a powerful being known as Huaxu (華胥). Huaxu gave birth to a twin brother and sister, Fuxi and Nüwa. Fuxi and Nüwa are said to be creatures that have faces of human and bodies of snakes. However, in some myths, Fuxi was held to be the creator, not Pangu, who worked alone and not with Nüwa. Fuxi was known as the "original god", and he was said to have been born in the lower-middle reaches of the Yellow River in a place called Chengji (成紀) (possibly modern Lantian, Shaanxi province, or Tianshui, Gansu province). A possible historical interpretation of the myth is that Huaxu (Fuxi's mother) was a leader during the matriarchal society (2600 BC) as early Chinese developed language skill while Fuxi and Nüwa were leaders in the early patriarchal society (2600 BC) while Chinese began the marriage rituals. A divinity Taihao (太皞, "The Great Bright One") appears, vaguely, in sources before the Han dynasty, independent from Fuxi. Later, Fuxi is identified with Taihao, the latter being his courtesy or formal name.
