Чжу Си
During the Song dynasty, the scholar Zhu Xi () added ideas from Daoism 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.
