Confucianism: Analects of Confucius, University, Doctrine of the Mean, Mencius, Xunzi.

Taoism: Laozi and Zhuangzi

Legalists: Guiguzi and Han Feizi

These three schools are well-known, and China's later thoughts or strategies of governing the country generally come from these three schools! And the three factions also have other theories! For example, "Guiguzi" is a combination of military strategists, Yin and Yang, Taoism and other theories!

There are also The Art of War by military strategists and The Art of War by Sun Bin!

Classic and historical subsets:

This is too much, and some of them overlap with a hundred schools of thought, because there are many Confucian classics, history, Confucius and condensed classics! Say something casually!

Classics: Shangshu, Zhouyi, Book of Songs, Book of Rites, etc.

History: Historical Records, History of Han, History of Later Han, History of the Three Kingdoms and other historical books, including Zuo Zhuan in the Spring and Autumn Period and Warring States Policy, can also be counted.

Zi: It's really the state where a hundred schools of thought contend, and later Huai Nan Zi! Lu's Spring and Autumn Annals! Zhu's "recent thoughts" is also counted!

Set: this is even more, such as poetry collections of past dynasties! For example: Complete Works of Li Taibai, Collected Works of Su Shi, etc! There are also selected books, such as Selected Works of Zhao Ming, A View of China's Ancient Literature, Poems of a Thousand Schools, Complete Poems of Tang Poetry and 300 Poems of Tang Poetry.
