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.
