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.

Xu Zhi (died 254) was a military general of the state of Cao Wei during the Three Kingdoms period of China. He participated in a battle against an invading army from Wei's rival state, Shu Han, led by the Shu general Jiang Wei. His name is sometimes incorrectly romanised as Xu Zi.
