He is traditionally accredited with transmitting Confucian teaching to Mencius[1] and writing the Doctrine of the Mean, Biaoji 表記, "Ziyi" (The Black Robes") 緇衣, and "Fangji" (The Record of the Dikes) 坊記, presently chapters of the Liji.

(Since Zisi's dates of life do not overlap with those of Mengzi, it has been suggested that the intermediary role in the transmission was played by Shi Shuo 世碩.

He attempted to analyse as many types of action as possible, and believed that wise people who are conscious of their moral and intellectual duties can copy the reality of the universe into themselves.

Li Xueqin suggests that it was done under influence of the text presently constituting the "Great Plan" (Hongfan) chapter of the Shangshu.

It was compiled by Wang Zhuo (汪晫 Wāng Zhuó) of the Song dynasty, but not recognized as authentic.
