Fuxi
Fuxi or Fu Hsi 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 2900 BC or 2000 BC. He is also said to be the originator of bagua (the eight trigrams) after observing that there were eight fundamental building blocks in nature: heaven, earth, water, fire, thunder, wind, mountain, and lake. These eight are all made of different combinations of yin and yang, which are what came to be called bagua.
