Cao Cao wrote a letter to Lü Bu, explaining the perilous situation the latter was in. Lü Bu became afraid and had the intention of surrendering, but Chen Gong felt that Cao Cao's army had travelled a long distance and would not be able to fight a prolonged battle. Chen Gong advised Lü Bu to garrison part of his forces outside the city, while the rest would remain with him inside, so that they can support each other if either side came under attack. Chen also said the best time to engage Cao Cao's forces would be months later, when Cao's supplies run out. Lü Bu agreed with the plan and wanted to leave Chen Gong and Gao Shun behind to defend Xiapi while he was stationed outside the city. However, Lü Bu's wife claimed that Chen Gong and Gao Shun could not get along with each other, so that would be a problem if Lü Bu was not around. She also felt that Cao Cao treated Chen Gong better (before the latter's defection to Lü Bu) than how Lü Bu was treating Chen now, so Chen might betray Lü Bu. Lü Bu thus aborted Chen Gong's plan.
