Zhang was not competent in military affairs and was unprepared, so the chances of success were high. Pang Tong considered this to be the best plan. The middle plan: Knowing that Yang Huai (楊懷) and Gao Pei (高沛) were famous generals who led strong troops defending Guantou, and that in the past they had advised Liu Zhang to send Liu Bei back to Jing Province. Before the army advances, spread false news that Liu Bei was returning to Jing Province saying that the region was in danger and that Liu Bei need to rescue it while making it look like the army will leave. With Liu Bei's reputation and wanting to see him leave, they would certainly come see him off with light cavalry away from the fortified mountain passes they were defending, kill them and take control of their positions and troops, and finally advance towards Chengdu. The lower plan: Retreat to Baidicheng and wait for another opportunity to attack. Pang Tong considered this to be the worst plan. Pang Tong told Liu Bei that if he took too much time and didn't go then he would be in great danger and couldn't last. Liu Bei chose the middle plan and executed it – he killed Yang Huai and Gao Pei, led his forces towards Chengdu and conquered several of Liu Zhang's territories along the way.

Pang Tong replied, "It was both yours and mine." Liu Bei laughed and the banquet continued. Xi Zuochi commented on this event and said : Pei Songzhi added : Death Pang Tong later participated in a battle against Liu
