《韩非子·内储说下六微》
哀公新得欢乐，对政事一定懈怠，孔子一定会加以劝谏；他一劝谏，必定会和鲁国轻易地断绝关系。 景公说： 很好。 
哀公新乐之，必怠于政，仲尼必谏，谏必轻绝于鲁。 景公曰： 善。 
Duke Ai has new joy and will definitely neglect political affairs. Confucius will definitely advise him; once he advises him, he will surely break up with the State of Lu easily. Jing Gong said: Very good.
