Cheng Hao 程颢

Born: 1032 CE (Luoyang, Henan Province)
Died: 1085 CE (Luoyang, Henan Province)
Dynasty: (Northern) Song
Association: Neo-Confucianism

Together with his brother, Cheng Yi, Cheng Hao, better known as a philosopher than as a poet, gave birth to the neo-Confucist movement in Song China. He was dismissed from government service for political reasons and returned to his native Henan Province to develop their school of philosophy.  Cheng Hao, in particular, emphasized calm introspection (in contrast to his brother's teachings to investigate the world and human affairs).
