History, or history for short, refers to the past events and actions of human society, as well as the systematic recording, interpretation and research of these events and behaviors. History can provide people today with understanding of the past and serve as a reference for future actions.

Miscellaneous poetry is also unique to ancient poetry. Poems vary in length, ranging from one character to more than a cross, and are generally a mixture of three, four, five, and seven characters, with seven characters being the mainstay, so they are customarily classified into the seven-character category. There are many miscellaneous poems in the Book of Songs and Han Yuefu folk songs.
