On the eve of the Battle of Yiling, Sun Quan was afraid of fighting on two fronts, so he bowed to Cao Wei.
Voluntarily became a vassal state of Cao Wei. And will wait for some defeated generals of the Wei state to be sent back. As a newly enthroned Cao Pi, this is a great good thing. Because of this act of Sun Quan, it fully shows that the State of Wu is afraid of the iron armor of the State of Wei. However, at this time, Liu Ye had written to Cao Pi, hoping that Cao Pi could take advantage of the emptiness of Eastern Wu and the shortage of troops to send troops to requisition. However, Cao Pi rejected Liu Ye's proposal. In the eyes of many people at that time, Cao Pi's choice not to take advantage of the false attack on Eastern Wu at that time may have been a waste of a good opportunity.
Great wisdom
But maybe this is Cao Pi's great wisdom. Why? When Cao Cao was alive, Liu Bei and Sun Quan had already met each other in order to compete for the land of Jingxiang, but later Liu Bei fought in order to deal with the Battle of Hanzhong.
He made peace with Sun Quan and divided the land of Jingxiang, bounded by Xiangshui, and the nan, lingling, and wuling counties of Jingzhou belonged to Liu Bei
Jiangxia County, Changsha County, and Guiyang County in Jingzhou belonged to Sun Quan. Why Cao Pi was reluctant to send troops to Eastern Wu at this moment was actually afraid that the past would happen again. In case that after they sent troops, the Sun and Liu families once again talked about peace, which would backfire. Therefore, cao Pi chose to accept Sun Quan's subservience and submission.
After the Battle of Yiling
Later, Sun And Liu's two families experienced the Battle of Yiling, although the war ended with a great victory for Eastern Wu. But both families became weak after the war. The Shu state almost subverted the newly established regime.
The State of Wu was also seriously injured by the attrition of the war and the casualties of the soldiers
。 Therefore, Cao Pi's move of sitting on the mountain and watching the tiger fight is very wise. But why did Cao Pi choose to attack Sun Quan instead of the more miserable Liu Bei?
The name of Wu Wu is justified
First, after the Battle of Yiling, the crisis in Eastern Wu was solved. Therefore, Sun Quan and Cao Pi tore their faces and established themselves as emperors. The original relationship between the monarchs and subjects of the cao and sun families changed in an instant, and Cao Pi had a good reason for cutting down Wu.
If Cao Pi was indifferent in the face of such an Eastern Wu, it would also be punching Cao Wei in the face.
geographical location
Second, although the Shu state declined, according to the geographical location of the Shu state, it was not easy to send troops to cut down Shu. Although Liu Bei was defeated at Yiling, before sending troops, Liu Bei deliberately left an army for Wei Yan to guard Hanzhong, and Shu would take Hanzhong. However, according to the actual situation at that time, wei Yan's army that remained in Hanzhong was not damaged in the slightest, and if he chose to send troops to cut down Shu at this time, it would definitely cause both sides to lose. Unlike Eastern Wu, the border between Cao Wei and Eastern Wu is very long, which means that it is very easy to send troops to the southeast.
Therefore, Cao Pi chose to send troops to Sun Quan instead of Liu Bei!
