What do the Four Books and Five Classics refer to?

Four Books and Five Classics: The general name of the four books and five classics refers to Confucian classics. The Four Books refer to Daxue, The Doctrine of the Mean, The Analects of Confucius and Mencius, and the Five Classics refer to The Book of Songs, Shangshu, Book of Rites, Zhouyi and Chunqiu. The Book of Rites usually includes three rites, namely, Yili, Zhou Li and the Book of Rites. Chunqiu is usually published separately from Zuo Zhuan, Gong Yang Zhuan and Gu Liang Zhuan, which explain Chunqiu, because its text is too brief. The naming of the Four Books began in the Song Dynasty, and the naming of the Five Classics began in Emperor Wu of the Han Dynasty.
