Cao Xiu
In October 222, Cao Pi launched the first of a series of invasions against Eastern Wu, the state founded by his rival, Sun Quan. He promoted Cao Xiu to Senior General Who Attacks the East (征東大將軍), granted him the yellow axe (a ceremonial axe given to newly appointed high-ranking generals), and ordered him, Zhang Liao and others to lead 20 armies to attack Dongkou (洞口; in present-day southern Jiangsu), where they defeated Wu forces led by Lü Fan. Cao Pi later promoted Cao Xiu to Governor of Yang Province.
