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.
