《韩非子·奸劫弑臣》
君臣之间不存在骨肉间的亲情，如果凭正直态度可以获得利益，那臣下就会经历侍奉君主；凭正直态度不可以求安，臣下就会营私来侵犯君主。
夫君臣非有骨肉之亲，正直之道可以得利，则臣尽力以事主；正直之道不可以得安，则臣行私以干上。
There is no family affection between the monarch and the minister. If a righteous attitude can gain benefits, then the minister will experience serving the monarch; if a righteous attitude cannot seek peace, the minister will seek personal gain to infringe upon the monarch.
