Xu Sheng
Xu Sheng's ego did not always lead to positive actions though. After the Battle of Ruxu in 217, Zhou Tai was appointed as the commander of the garrison at Ruxu, with Xu Sheng and Zhu Ran as his subordinates. However, both of them were unwilling to submit to Zhou Tai's command, citing the latter's humble origins in comparison to their more affluent family backgrounds. When Sun Quan heard about it, he visited Ruxu and hosted a party for all the officers there, during which he asked Zhou Tai to display his battle scars for all to see. He later awarded Zhou Tai with an imperial parasol. After that incident, Xu Sheng and Zhu Ran agreed to submit to Zhou Tai's command.
