The Classic of Mountains and Seas, also known as Shanhai jing, formerly romanized as the Shan-hai Ching, is a Chinese classic text and a compilation of mythic geography and beasts. Early versions of the text may have existed since the 4th century BCE, but the present form was not reached until the early Han dynasty. It is largely a fabulous geographical and cultural account of pre-Qin China as well as a collection of Chinese mythology. The book is divided into eighteen sections; it describes over 550 mountains and 300 channels.

The Chinese classics or canonical texts are the works of Chinese literature authored prior to the establishment of the imperial Qin dynasty in 221 BC. Prominent examples include the Four Books and Five Classics in the Neo-Confucian tradition, themselves an abridgment of the Thirteen Classics. The Chinese classics used a form of written Chinese consciously imitated by later authors, now known as Classical Chinese. A common Chinese word for "classic" literally means 'warp thread', in reference to the techniques by which works of this period were bound into volumes.
