Description Chinese myth of creation. In the beginning there was nothing in the universe except a formless chaos. However this chaos began to coalesce into a cosmic egg for eighteen thousand years. Within it, the perfectly opposed principles of yin and yang became balanced and Pangu emerged from the egg. Pangu set about the task of creating the world: he separated Yin from Yang with a swing of his giant axe, creating the Earth (murky Yin) and the Sky (clear Yang).
