Huang Zu
In 200 CE, the warlord Cao Cao, who controlled the Han central government and the figurehead Emperor Xian, sent Mi Heng, a talented but obnoxious scholar, as a guest to Liu Biao. Although Mi Heng and Liu Biao got along well initially, Mi Heng started to insult and belittle Liu Biao after some time. Unable to put up with Mi Heng's obnoxious behaviour, Liu Biao then sent him to Huang Zu. Huang Zu could not tolerate Mi Heng and had him executed.
