満寵
Man Chong was not on good terms with his colleague, Wang Ling, who spread rumours that Man Chong was addicted to alcohol, physically unfit for his job, and unruly and defiant. When the rumours reached the Wei imperial capital Luoyang, an official Guo Mou () suggested to the emperor to summon Man Chong to Luoyang and see if the rumours were true, as opposed to immediately removing Man Chong from office. Cao Rui heeded the suggestion. When Man Chong met the emperor, he appeared to be in good health and remained sober after consuming one "dan" of alcohol. Cao Rui thus concluded that the rumours were untrue and ordered Man Chong to return to his post. Man Chong, however, wanted to remain in Luoyang so he repeatedly sought permission from Cao Rui but was denied. Cao Rui told him, "In the past, Lian Po ate and drank heavily to show that he was in good health, while Ma Yuan turned his body to look backward while he was on horseback to show that he was still fit for battle. You aren't even old, yet you say you're old. Why don't you compare yourself with Lian Po and Ma Yuan? You should be thinking about defending the border and serving your country."
