In 221, Liu Bei declared himself emperor and founded the state of Shu Han to challenge Cao Pi's claim to the Han throne. In the following year, when Liu Bei was away on a military campaign against his ally-turned-rival Sun Quan, Yang Yi offended Liu Ba, the Prefect of the Masters of Writing (). Liu Ba reassigned Yang Yi to be the Administrator of Hongnong Commandery (弘農郡; around present-day Lingbao City, Henan); this was only a nominal appointment because Hongnong Commandery was not Shu territory.
