In the morning, when Zhang Xiu received news that Cao Cao's camps were empty, he thought that Cao Cao had fled so he wanted to lead his troops in pursuit. However, Jia Xu, his adviser, warned him not to pursue Cao Cao and predicted that he would lose if he did. Zhang Xiu ignored him and went ahead. Just as Jia Xu foresaw, Zhang Xiu fell into Cao Cao's ambush and was soundly defeated. When Zhang Xiu came back after his defeat, Jia Xu told him to attack again and predicted that he would win this time. Zhang Xiu said, "I didn't listen to you earlier, which resulted in my defeat. Now that I have lost, why should I attack again?" Jia Xu replied, "Changes have taken place. You'll win if you swiftly attack now." Zhang Xiu heeded Jia Xu's advice and attacked Cao Cao again. He won the battle the second time.
