官渡の戦い
Shen Pei's two sons were captured by Cao Cao's forces during the Battle of Guandu. After the battle, Meng Dai (孟岱), one of Yuan Shao's subordinates, slandered Shen Pei in front of Yuan Shao. Guo Tu and Xin Ping agreed with what Meng Dai said, so Yuan Shao removed Shen Pei from his command in Ye city and replaced him with Meng Dai.
