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 Xi
Zhu Xi wrote what was to become the orthodox Confucian interpretation of a number of concepts in Taoism and Buddhism. While he appeared to have adopted some ideas from these competing systems of thought, unlike previous Neo-Confucians he strictly abided by the Confucian doctrine of active moral cultivation. He found Buddhist principles to be darkening and deluding the original mind as well as destroying human relations.
