The Book of Rites University was never published separately before the Southern Song Dynasty. According to legend, it was written by Zeng Shen, a disciple of Confucius (505-434 BC). In the Tang Dynasty, Han Yu and Li Ao regarded Daxue as a Confucian classic as important as Mencius and Mencius. In Song Dynasty, Cheng Er and Zhu Xizu expounded this viewpoint and praised its position in Confucian classics, aiming at promoting Neo-Confucianism. Zhu called Daxue, The Doctrine of the Mean, The Analects of Confucius and Mencius "Four Books", which were published in the first year of the Southern Song Dynasty (1 190) and engraved into Notes on Four Books. Because The Analects of Confucius recorded Confucius' words and deeds, The University was written by Ceng Zi, The Doctrine of the Mean. During Yuan You's reign, the four books became the required classics for scholars.
