Cao Xiu
Following Cao Cao's death in March 220, his son Cao Pi succeeded him as the (vassal) King of Wei (魏王) and Imperial Chancellor (丞相) of the Eastern Han dynasty. Cao Pi appointed Cao Xiu as General Who Leads the Army (領軍將軍) and enfeoffed him as the Marquis of Dongyang Village (東陽亭侯) in recognition of his past achievements. When Xiahou Dun died in June 220, Cao Pi ordered Cao Xiu to replace Xiahou Dun as the supervisor of all military operations, promoted him to General Who Guards the South (鎮南將軍) and granted him acting imperial authority. He held Cao Xiu's hands while personally seeing him off.
