Nüwa, also read Nügua, is the mother goddess of Chinese mythology, the sister and wife of Fuxi, the emperor-god. She is credited with creating humanity and repairing the Pillar of Heaven.
As creator of mankind, she molded the upper-class individually by hand with yellow clay, and as she grew tired, she instead used a string to pull up the clay faster and form the lower-class.
In the Huainanzi, there is described a great battle between deities that broke the pillars supporting Heaven and caused great devastation. There was great flooding, and Heaven had collapsed. Nüwa was the one who patched the holes in Heaven with five colored stones, and she used the legs of a tortoise to mend the pillars.
There are many instances of her in literature across China which detail her in creation stories, and today remains a figure important to Chinese culture.
