《孔子家语·六本》
孔子说： 颜回具有作为君子的四种品德：努力推行仁义、虚心接受劝告、害怕接受俸禄、谨慎修养身心。
孔子曰： 回有君子之道四焉。强于行义，弱于受谏，怵于待禄，慎于治身。
Confucius said, “Yan Hui has the four virtues of a gentleman: the implementation of benevolence and righteousness, the humility to accept criticism, the fear of recompensing himself, and the caution of cultivating his own body and mind.”
