Sometime between June and August 215, Sun Quan sent Zhuge Jin as his representative to visit his ally, Liu Bei, who had recently seized control of Yi Province (covering present-day Sichuan and Chongqing). Zhuge Jin's task was to ask Liu Bei to "return" the territories in southern Jing Province (covering present-day Hubei and Hunan) to Sun Quan, according to an earlier agreement that Liu Bei would only use Jing Province as a temporary base and would return them to Sun Quan once he found another base. However, Liu Bei refused and said he would return the territories after he seized Liang Province.
