Chen Shou, who wrote Guan Yu's biography in the "Sanguozhi", commented on the latter as such: "Guan Yu and Zhang Fei were referred to as mighty warriors capable of fighting thousands of enemies. They were like tigers among (Liu Bei's) subjects. Guan Yu and Zhang Fei both had the style of a "guoshi" Guan Yu repaid Cao Cao's kindness while Zhang Fei released Yan Yan out of righteousness. However, Guan Yu was unrelenting and conceited while Zhang Fei was brutal and heartless. These shortcomings resulted in their downfalls. This was not something uncommon."
