In 220, Cao Pi forced Emperor Xian to abdicate the throne to him, thus ending the Han dynasty. He then established the state of Wei with himself as its first emperor. After ascending the throne, Cao Pi appointed Jia Xu as Grand Commandant (太尉) and promoted him from a Marquis of a Chief Village to the Marquis of Weishou District (魏壽鄉侯), with a marquisate of 800 taxable households. Jia Xu's promotion was allegedly an expression of gratitude from Cao Pi, who wanted to thank him for helping him seize the succession years ago. Sun Quan laughed when he heard that Cao Pi had appointed Jia Xu as his Grand Commandant.
