Ding Yi (Han dynasty)
Ding Yi (died 220), courtesy name Zhengli, was an official serving under the warlord Cao Cao during the late Eastern Han dynasty of China. Life Ding Yi was from Pei State (), which is around present-day Suixi County, Anhui. His father, Ding Chong (), was an old acquaintance of Cao Cao, the warlord who controlled the Han central government and the figurehead Emperor Xian from 196 to 220. Ding Chong served as the Colonel-Director of Retainers () in Cao Cao's administration. After Ding Chong's death, Cao Cao wanted to arrange for Ding Yi to marry one of his daughters, Princess Qinghe (). However, Cao Cao's eldest surviving son, Cao Pi, strongly opposed because Ding Yi had an eye disorder which affected his physical appearance and hence made him an unsuitable spouse for Princess Qinghe. Cao Pi then suggested to his father to let Princess Qinghe marry Xiahou Mao instead; Cao Cao agreed. Ding Yi hated Cao Pi for spoiling his chance of becoming Cao Cao's son-in-law, so he grew determined to oppose Cao Pi. He became close to Cao Pi's younger brother Cao Zhi, who was Cao Pi's rival in a power struggle over the succession to their father's position
