Cheng Yu, an adviser to Cao Cao, also once mentioned that Guan Yu and Zhang Fei were "capable of fighting thousands of enemies". In the main text of Zhang Fei's biography, Chen Shou wrote that Zhang Fei respected virtuous persons and detested those of vile character. Liu Bei had constantly warned Zhang Fei about his barbaric behaviour as he once told the latter: "You have dealt out far too excessive punishments. You often flog your men, who are actually the ones who will carry out your orders. Your behaviour will get you into trouble." Zhang Fei still did not change his ways.
