According to the Records of the Three Kingdoms, before the battle of Guandu, Yuan Shao's camp was divided into two factions. People headed by Tian Feng and Jushou advocated consolidating the base areas, developing the economy and people's livelihood, training the army, and then reporting their achievements to Xian Di controlled by Cao Cao. If Cao Cao gets in his way, he will fall into a political disadvantage on the grounds that Cao Cao gets in my way. At the same time, a small army was sent to harass Cao Cao and engage in small-scale guerrilla warfare with Cao Cao, which made him exhausted. And believe that adhering to this policy, "a few years can decide major events." The other faction, headed by Guo Tu and Shen Pei, thinks that Yuan Shao's army is several times more than Cao Cao's, and its strength is dominant. It's time to confront Cao Cao. Facts have proved that Tian Feng and the giant hand are right. As for Xu You's attitude on this issue, there is no clear record. During the stalemate in the war, Xu You proposed to send heavy troops to attack Xu Du, but it was not adopted by Yuan Shao.
