Shen Pei
In the year 200, Yuan Shao clashed with his rival Cao Cao at the Battle of Guandu. During the battle, two sons of Yuan Shao's adviser Shen Pei were captured by Cao Cao's forces. Meng Dai (孟岱), one of Yuan Shao's subordinates, was not on good terms with Shen Pei, so he asked his colleague Jiang Qi (蔣奇) to pass a message to Yuan Shao: "Shen Pei has been behaving autocratically and he has strong support from his kinsmen. Now that his two sons have been captured by the enemy, he may think of defecting to the enemy to save his sons." Xin Ping and his colleague Guo Tu agreed with Meng Dai. Yuan Shao thus appointed Meng Dai as his new army supervisor and ordered him to replace Shen Pei as the officer guarding his home base in Ye (present-day Handan, Hebei).
