诸葛瑾
In late 222, Sun Quan, who was previously a vassal king under the Cao Wei state, broke ties with the Wei emperor Cao Pi and declared himself the independent ruler of his Eastern Wu state. He promoted Zhuge Jin to General of the Left (), granted him acting imperial authority, and ordered him to station at Gong'an County to oversee the Wu defences in southern Jing Province. He also enfeoffed Zhuge Jin as the Marquis of Wanling ().
