《韩非子·难三》
君主如果不处罚他们而自以为有齐桓公、晋文公的德行，就是用仇人为臣而不能洞察阴谋，反而给他们提供很多活动条件，自认为他们都是贤臣而不加戒备。那么他们即使丧失了政权，不也是理所当然的吗？
君必不诛而自以为有桓、文之德，是臣仇而明不能烛，多假之资，自以为贤而不戒，则虽无后嗣，不亦可乎？
If the monarch does not punish them but thinks he has the virtue of Qi Huangong and Jin Wengong, that is, he uses enemies as ministers but cannot see through conspiracies, but provides them with many conditions for activities, and thinks they are all worthy ministers but does not take precautions. , Then even if they lose their power, isn't it natural?
