《资治通鉴·周纪·周纪五》
孔斌在魏国任相共九个月，每次提出重大的建议都不被魏王采用，于是喟然长叹： 建议不被采纳，是我的建议有不合适的地方，建议不合君主的心意，我再做他的官，享用他的俸禄，是不做事白吃饭，我的罪过也太大了！ 
子顺相魏凡九月，陈大计辄不用，乃喟然曰： 言不见用，是吾言之不当也。言不当于主，居人之官，食人之禄，是尸利素餐，吾罪深矣！ 
Kong Bin served as prime minister of Wei for a total of nine months, but each time he made an important suggestion, it was not adopted by the King of Wei. So he sighed deeply: "My suggestions are not being adopted, which means there must be something wrong with my suggestions. My suggestions do not conform to the king's wishes, and if I continue to serve as his official and enjoy his salary, I will be eating for free and doing nothing, and my crime will be too great!"
