Yuan Shao
After Yuan Shao lost the Battle of Yan Ford (a follow-up to the Battle of Boma), Ju Shou urged him to change strategy and fight a long-term war with Cao Cao so as to gradually wear down Cao Cao's forces over time. However, Yuan Shao refused to listen and insisted on sending his troops on an all-out confrontation with Cao Cao. In the initial stages of the Battle of Guandu, after Cao Cao's forces attacked one of Yuan Shao's supply convoys, Yuan Shao ordered his general Chunyu Qiong to take charge of transporting supplies and defend the supply depot at Wuchao (). When Ju Shou advised Yuan Shao to send Jiang Qi () to lead a unit to escort the supply convoy, Yuan Shao ignored him again. Yuan Shao ultimately lost the Battle of Guandu against Cao Cao when the latter led a successful raid on Wuchao and destroyed all of Yuan Shao's supplies.
