The Shan Hai Jing, also known as the Classic of Mountains and Seas, is an ancient Chinese text that dates back to the 4th century BCE. It is a collection of mythological geography, describing various mountains, rivers, and regions in China, along with the creatures and deities that inhabit them. The text is divided into 18 sections, blending folklore, mythology, and early Chinese cosmology. This work is significant for its rich descriptions of mythical beings, such as the Qilin and the Dragon, and its influence on Chinese culture and literature. The Shan Hai Jing serves as an important resource for understanding ancient Chinese beliefs, geography, and the relationship between humans and nature.
