Korean Confucianism
Under the succeeding Han Dynasty and Tang Dynasty, Confucian ideas gained even more widespread prominence. During the Song Dynasty, the scholar Zhu Xi (AD 1130–1200) added ideas from Taoism and Buddhism into Confucianism. In his life, Zhu Xi was largely ignored, but not long after his death his ideas became the new orthodox view of what Confucian texts actually meant. Modern historians view Zhu Xi as having created something rather different, and call his way of thinking Neo-Confucianism. Neo-Confucianism held sway in China, Japan, Korea and Vietnam until the 19th century.
Shizi (book)
The oldest surviving reference to Shizi is found in the (91 BCE) "Shiji" "Scribal Record" biography of Xunzi (c. 312–230 BCE). 
And (in addition to Xun Zi, the state of) Zhao also had Gongsun Long, who made arguments about the similarity and difference of hardness and whiteness, and the sayings of Ju Zi; (the state of) Wei had Li Kui (with his) teaching on fully using the powers of the land; (the state of) Chu had Shizi, Chang Lu, and Yu Zi from A in it. Following from Meng Zi down until Yu Zi, the world has their writings in abundance; therefore (I) will not discuss their biographies. (tr. Fischer 2012:794-797)
