The article presents a study that deals with the role of Chinese scholar Chu Hsi in Sung-Ming Neo-Confucianism. Topics include Hsi's effort to establish the orthodox line of transmission of the Way, the preface to his book "Commentary on the Doctrine of the Mean" which traced the line back to ancient sage-emperors, and compilation of the "Neo-Confucian Anthology: Reflection on Things at Hand" with his friend Lu Tsu-ch'ien.
