In primitive times, people unconsciously visualized and personified the power of nature, thus forming absurd stories and legends. It is the product of low productivity in the early days of mankind, a naive explanation and ideal pursuit of the origin of the ancient universe, natural phenomena and social life, and full of romantic colors of active fighting. It does not emphasize the depiction of characters and background description, but only pays attention to the description of grotesque events of "God". Myth is the bud of religion, the origin of art and the origin of novel. Many ancient myths are preserved in China's Classic of Mountains and Seas and Huainanzi. In the literary creation of past dynasties, works that reflect reality and satirize society with the theme of God are usually called myths. The famous ancient Greek mythology is a treasure in the treasure house of world literature.

The Goddess Chang'e flying to the moon, Butian, Pangu Tiankai and Houyi Shooting the Sun are all from Shan Hai Jing.
