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.
Zhu Huan
Zhu Huan (177–238), courtesy name Xiumu, was a military general of the state of Eastern Wu during the Three Kingdoms period of China. Although he started his career early under the warlord Sun Quan, he did not receive any important responsibilities until after the Battle of Jiangling in 209. Since then, Zhu Huan had taken charge of some local defences and successfully quelled a few rebellions. Between 222 and 225, when Cao Pi, the emperor of Wu's rival state Wei, launched a three-pronged invasion of Wu, Sun Quan appointed Zhu Huan as a military commander to resist the Wei invaders. Zhu Huan defeated the Wei general Cao Ren at the Battle of Ruxu (222–223).
