Zhong Hui (225 – 3 March 264), courtesy name Shiji, was a Chinese calligrapher, essayist, military general, and politician of the state of Cao Wei during the Three Kingdoms period of China. He was the younger son of Zhang Changpu with Zhong Yao, who served as the Grand Tutor in the Wei imperial court. He was already known for being insightful, intelligent and knowledgeable since he was young. Zhong Hui rose to prominence in the 250s when he became a close aide to Sima Zhao, the regent and de facto ruler of Wei. He advised Sima Zhao on how to deal with the Third Rebellion in Shouchun from 257–258 and was highly regarded by the latter. With Sima Zhao's help, Zhong Hui steadily moved up the ranks and became one of the key figures in the Wei government.
