of Wei and Imperial Chancellor of the Han Empire. He first appointed Xiahou Shang as a Regular Mounted Attendant and later promoted him to Commandant of the Central Army (). As a reward for Xiahou Shang's contributions, Cao Pi also enfeoffed him as the Marquis of Pingling Village (). In late 220, Cao Pi usurped the throne from Emperor Xian, ended the Eastern Han dynasty, and established the Cao Wei state with himself as the new emperor.
