Later, Zhuzi, The Analects of Confucius, The Doctrine of the Mean, and Mencius were published as four books. With the rise of Zhuzi Studies to the official position, The University became a classic read by various schools together with the four books, resulting in Mao Qiling's so-called academic situation that Yu Saito had a university and the Five Classics had no university.

The "Three Outlines" and "Eight Items" put forward in "University" emphasize that self-cultivation is the premise of governing people, and the purpose of self-cultivation is to govern the country and the world, which shows the consistency between governing the country and the world and personal moral cultivation.

The full text of "Da Xue" is concise, profound and far-reaching. This paper mainly summarizes the pre-Qin Confucian moral cultivation theory, as well as the basic principles and methods of moral cultivation, and also systematically discusses the Confucian political philosophy, which has profound enlightenment for being a man, doing things and governing the country.

Appreciation of university content

The outlook on life put forward by the university is inextricably linked with Confucianism, which is basically a further expansion of the Confucian outlook on life. This outlook on life requires paying attention to personal cultivation and embracing positive goals. This kind of cultivation and requirement is mainly based on Confucian morality. The three cardinal guides and eight aims have class nature, and "virtue" and "supreme goodness" are the political requirements and ethical standards of feudalism for monarchs. Eight items, such as "discipline" and "knowledge", require the combination of political ideas and ethical thoughts in the three programs in terms of self-cultivation.

Universities also inherited Confucius' theory of benevolent governance and Mencius' theory of people-oriented. Rulers in universities pretend to be "elders" and "parents of the people", but in fact they still say this from the standpoint of exploiters. Their so-called "love for the people" and "non-violence" are just to maintain the economic foundation of their superstructure-productivity. Only in this way can their unproductive and exploitative lives be consolidated.
