When news of the attack on Wuchao reached Yuan Shao's camp, Zhang He advised Yuan Shao: "Cao Cao's forces are well-trained so they will definitely defeat Chunyu Qiong. If Chunyu Qiong is defeated, all is lost for you, General. You should immediately dispatch forces to reinforce Wuchao." Yuan Shao's adviser Guo Tu disagreed with Zhang He: "Zhang He's idea isn't right. Why don't we attack Cao Cao's main camp instead? He will definitely head back to defend his camp. In this way, we can stop the attack on Wuchao without having to send reinforcements there." Zhang He replied: "Cao Cao's camp is well-defended and can't be conquered easily. If Chunyu Qiong is taken captive, we will all become prisoners-of-war."
