Zhu Xi

Zhu Xi (1130 - 1200) in China was a Confucian who is one of most significant Neo-Confucians[?]. He taught at the famous White Deer Grotto Academy[?] for some time. Considered unorthodox in their time, the Song Dynasty (960-1279), he and his fellow scholars added additional classic books; the Four Books, the Great Learning, and the Doctrine of Mean[?]. Their writings were not widely recognised in Zhu Xi's time, however they subsequently became accepted as standard commentaries on the Confucian classics.
