程昱
The year 194 was a hard time for Cao Cao, because in addition to losing several battles to Lü Bu around Puyang, a widespread famine also broke out in Yan Province (but this also forced Lü Bu to retreat). For once, Cao Cao thought about relinquishing his position in Yan Province, and prepared to surrender to Yuan Shao. Nevertheless, Cheng Yu rebuked Cao Cao by saying that he had a calibre greater than just being a subject under Yuan Shao, and it was shameful for a genius to submit to a man who only enjoyed an overvalued fame. Cheng Yu said to Cao Cao: "Even a mere warrior like Tian Heng knew about shame, how could you act so shamefully to surrender to Yuan Shao?" However, Cheng Yu's heroic speech was way easier to say than to do, because Cao Cao's army had already been running out of food. Nevertheless, not wanting to be disgraced, Cao Cao appeared to listen to Cheng Yu, but asked him to prepare three days' worth of supplies. Unprepared to be asked to deal with this problem, Cheng Yu insanely devised a very vicious strategy: he personally led an armed force to pillage his hometown and abducted his townsfolk, who would then be slaughtered like pigs for Cao Cao's army to feed on.
