Zhu Xi

Zhu Xi or Chu Hsi (Chinese Neo-Confucian philosopher, Song Dynasty, 1130–1200). Considered the greatest of the Neo-Confucian scholars, Zhu Xi’s thought initially represented a challenge to orthodox Neo-Confucianism. His commentaries on "The Four Books", however, would eventually form the basis for all civil service examinations conducted in China for the next 400 years, until that system was abolished in 1905.
