Zhu Xi
Study the principle (li) of things to perfect oneself.
Great Learning by Chapters and Sentences (Daxue zhangju) essential
He reorganises a chapter of the Book of Rites into a "classic" and ten chapters of "commentary", and writes himself the missing chapter on "investigating things" (saying he takes up Cheng Yi's thought). He makes this short text the entrance to the whole curriculum.
Collected Commentaries on the Analects and Mencius (Lunyu jizhu, Mengzi jizhu) essential
Prefaced in 1177 and revised until his death. With the Great Learning and the commentary on the Doctrine of the Mean, they form the Four Books.
Reflections on Things at Hand (Jinsi lu)
A collection of 622 sayings by four Northern Song masters (Zhou Dunyi, the Cheng brothers, Zhang Zai), chosen with Lü Zuqian. The sayings are not his: his contribution is the selection and the order.
Classified Conversations of Master Zhu (Zhuzi yulei)
140 chapters compiled by Li Jingde from his students' notebooks, seventy years after his death. Each entry ends with the name of the student who recorded it. Our "§k" numbering does not come from the edition.
Collected Writings (Zhuzi wenji: letters, essays, prefaces)
His letters and essays, gathered after his death. They are not in our corpus.
Family Rituals (Jiali)
A manual of family ceremonies attributed to him. His exact role in the writing has been debated; most scholars credit him with a first version.
