But the king didn't agree with him."I think we should treat the prisoners of war differently by differing them into those who are guilty and those who are not. The guilty ones will be sentenced to death in order to avoid future disasters." Another official put forward his suggestion.
The king didn't think it was a proper way, either.
Then a third one said, "Your majesty, I think all the prisoners should be set free and sent back home to work in the fields and support themselves by their own labor. Moreover, you should keep strictly the rules for reward and punishment and treat your relatives and friendsimpartially.The people are sure to believe in you if you administer our country by morals and laws."
The king thought the official's proposal was quite reasonable so he accepted and followed it.As a result, the domestic situation soon settled down and gradually the country became more stable and stronger.
The idiom is then used to mean that if you love someone,you'll love people and things relative to him as well.
