was made a Censor. But finding himself in opposition to the powerful Wang An-shih, he thought it desirable to apply for a provincial appointment, and served in Shensi and (in 1075) in Honan. Soon afterwards he retired to Lo-yang, and devoted himself to study and teaching until his death. He was the author of the 定心書 and was tutor to the great Chu Hsi. Posthumously ennobled as Earl, he was canonised as 純, and in 1241 admitted to the Confucian Temple.
