Confucian Classics, as a Confucianism with yin and yang and five elements, has changed in the following aspects.

First of all, with the help of the theoretical framework of the theory of Yin-Yang and Five Elements, the scale of the study of "the unity of man and nature" in Confucian classics is constructed. One of the basic characteristics of Confucian Classics in Han Dynasty is its theoretical system of "the unity of man and nature". Zou Yan's theory of "harmony between man and nature" is called "on heaven". He combined the theory of yin and yang with the theory of "five elements" and used "news of yin and yang" to explore the reasons for the change of the universe. Dong Zhongshu absorbed this theoretical achievement, took Yin-Yang and Five Elements as the framework of his theoretical system, and injected traditional Confucian political and ethical thoughts, such as comparing Yin-Yang with three cardinal guides and comparing Five Elements with others, thus completing the theoretical foundation and transformation of Confucian Classics in Han Dynasty.

Secondly, the methodology of Confucian classics is established by using the reasoning mode of yin-yang and five elements theory. The methodology of Confucian classics in Han dynasty has the characteristics of empiricism and induction, which is obviously influenced by the theory of Yin-Yang and Five Elements. Historical Records, Mencius and Xun Qing, when discussing Zou Yan's thoughts, said: "It is a profound understanding of Yin and Yang news that leads to circuitous changes. There are more than 100,000 words in the Great Sage. Its language is not impressive. " The mode of "pushing big" has evolved into Dong Zhongshu's empirical thinking of "being similar to people" (Spring and Autumn Yin and Yang). Zou Yan's theory of Yin-Yang and Five Elements has a mystical tendency, which has a far-reaching influence on Confucian classics in Han Dynasty. For example, the classic masterpiece of modern Confucianism, Biography of the Spring and Autumn Ram, has many different meanings.

Third, part of the contents of Qi Xue entered Confucianism, and the Confucian classics were mixed. The theory of yin-yang and five elements has the characteristics of mixing, which combines the theory of yin-yang and five elements and "benevolence, righteousness, frugality and the use of six parents" The theory of Yin-Yang and Five Elements embodies the openness and compatibility of Qi culture, and Confucian classics in Han Dynasty was obviously influenced. He also talked about "strength", "rewarding the good and punishing the evil" and "judging the name, judging the quality and pointing to the reality", which showed the characteristics of "dominating the Tao", while Dong Zhongshu talked about "being a monarch, living in a position of inaction, teaching without words, being silent and invisible, holding on for no reason, and being the source of the country", which obviously absorbed the thought of Taoism's Huang Lao theory.
