Sun Quan ignored Liu Bei and sent his officials to assume office in the three commanderies of Changsha (), Lingling () and Guiyang () in southern Jing Province. However, Guan Yu, Liu Bei's general in charge of defending those territories, drove Sun Quan's officials away. An enraged Sun Quan then ordered his general Lü Meng to lead 20,000 troops to seize the three commanderies by force. After a standoff between both sides and tense negotiations, Liu Bei agreed to divide southern Jing Province between his and Sun Quan's domains along the Xiang River: Liu Bei would keep Nan, Lingling and Wuling commanderies in the west, while Sun Quan would take Changsha, Jiangxia and Guiyang commanderies in the east.
