Lu Su and Guan Yu then held talks to discuss the territorial dispute. During the negotiations, both sides stationed their soldiers more than 100 paces away from the meeting area and the officers present at the talks were each armed with only a blade weapon. Although the talks were inconclusive, the territorial dispute eventually ended by the end of August 215 when Liu Bei decided to give in upon learning that Cao Cao was attacking Hanzhong Commandery. As Hanzhong was the "northern gateway" into Yi Province, Cao Cao would pose a greater threat to Liu Bei's base in Yi Province if he succeeded in conquering Hanzhong, so Liu Bei had to switch to countering Cao Cao in Hanzhong. Liu Bei and Sun Quan then withdrew their forces after agreeing to divide southern Jing Province between them along the Xiang River.
