Sun Ce wanted to sneak up on Xudu during the battle of Guandu. Why didn't Cao Cao take precautions when he knew about it?

Because Cao Caoyou this kind of confidence, think Sun Ce won't sneak attack. Yuan Shao went all out to fight Cao Cao, not the kind who left after a battle. War is actually a life-and-death struggle. Sun Ce attacked Xudu, Cao Cao's lair. The reason why Cao did not save is very simple; Here and Lombardi is imminent, if because Sun Ce sneak attack many, and withdrawal; It's a joke that Yuan Shao will let Cao Cao go. Since Sun Ce attacked many capitals, wouldn't it be over for Yuan Shao to attack Cao again? But Cao Cao doesn't think so. If Xu is lost, you can get it back, because it is too far from Wu Dong to Xu. Even if Wu Dong's army occupied Xudu, they would only fight alone.

Can Wu Dong stay still after such a long time? Don't forget that Wu Dong has other advantages. Howie and Chen Deng, even the soldiers who haven't boarded Sun Ce have arrived in Xudu, and Jiangdong has fallen into the hands of others. Taking such a big risk to sneak up on Xudu in exchange for a Han Xiandi; This trump card in his hand may not be like Cao Cao's holding the emperor to the princes, and even the princes will rise up and attack him. Cao Cao didn't believe that Sun Ce dared to sneak attack Xu Du, and Sun Ce didn't have a chance to sneak attack. ?

So, when Sun Ce ambushed Cao, he didn't know who put the smoke bomb. Anyway, Cao Cao ignored it and was unmoved. After all, the purpose of Yuan Shao's going south is clear, that is, to slowly annex Cao Cao, and then eat other governors to achieve the ideal of hegemony. Higher is to replace the Han Dynasty. Cao Cao fights for survival, or he dies. The best outcome is to surrender to Yuan Shao. Did Cao do it? I would rather let the whole world fail me than let me fail the whole world. Cao Cao will not give up. Yuan Shao contended for hegemony, Sun Ce contended for the Han Emperor, and Liu Bei also contended for the Han Emperor.

Finally, Cao Cao won, reluctantly, really reluctantly. Without the strategizing of many great advisers under Yuan Shao, Cao Cao could not defeat Yuan Shao, but he could defeat Liu Bei. In fact, Liu Bei was involved, defeated and fled everywhere. Sun Ce's attack on Xudu was intentional and inorganic, but he had the courage and no advantage. Sun Quan stabilized Jiangdong, and later, he became a strong man. Cao Cao lost the battle of Guandu, Liu Bei also lost, and Yuan Shao was defeated directly. But Wu Dong became stronger.
