There are many different ways to classify ancient Chinese mythology. The following are some of the common classifications: 1. Mythology of Gods: refers to stories about natural gods such as heaven and earth, mountains and rivers, rivers, vegetation, insects, fish, birds and beasts, etc., such as the Classic of Mountains and Seas. 2. Mythology of human gods: refers to stories about humans and gods, such as the Romance of the Gods. 3. Xianxia Mythology: refers to stories about immortals, demons, and ghosts, such as Journey to the West. 4. Wuxia myths: refers to stories about immortals and martial arts characters, such as Water Margins. These classifications were not mutually exclusive, but were based on different perspectives and narrative methods. However, due to the differences in ancient cultures, these classifications may have some differences and limitations in some aspects. For example, the myths of gods and Xianxia often involved some Xianxia elements such as martial arts, magic, etc. These elements were no longer popular in modern literature. Wuxia myths, on the other hand, focused more on describing the character's personality, emotions, and experiences, so there might be some limitations in narration. Therefore, although there are many different classifications of ancient myths, they are not necessarily compatible because they are subject to different restrictions and influences in different eras and cultural backgrounds.
