The historization of China myth is the conscious or unconscious behavior of historians and thinkers. It is generally believed that the image in ancient mythology has experienced a development process from animal shape, half-man, half-beast shape to human shape. In orthodox historians or Confucian classics, the divine image of half man and half beast has been obliterated, because it is difficult to bring this image into the historical pedigree and it also violates the principle of rationalization. In addition, there are other myths that violate the principle of rationalization, and they have also been deleted. For example, the ancient edition of Huainanzi contains the myth that the goddess Chang 'e of the Goddess Chang'e flying to the moon "entrusted herself to the moon for the sake of toads and the essence of the moon", but the present edition of Huainanzi no longer exists. Another example is that the Yellow Emperor has four virtues.
