Abstract
Cheng Hao was a Confucian thinker during the Song dynasty. He strove to restore and reconstruct classical Confucianism. Although his theses were inherited from the Confucian classic, including the Anatects, Mencius, the Classic of Changes, and the Doctrine of the Mean, his interpretations offer learners new insight and perspective in understanding Confucianism. He and his younger brother, Cheng Yi, are commonly referred to as the “Two Chengs” for their parallel efforts in laying the groundwork of Neo-Confucianism.
