In ancient China, there was a state called Zhou. One day, the King of Zhou sought advice from his officials on how to handle prisoners of war.
The first official said, "I have heard a saying: 'If you love someone, you will love even the crows on his roof; if you hate someone, you will hate even the walls of his house.' These prisoners were our enemies. In my opinion, we should execute them all."
The king disagreed.
A second official proposed, "We should differentiate the prisoners, separating the guilty from the innocent. The guilty should be put to death to prevent future trouble."
The king found this suggestion also unsatisfactory.
Finally, a third official advised, "Your Majesty, I believe we should release all prisoners and send them home to farm and support themselves through their own labor. Furthermore, you must enforce rules of reward and punishment strictly and impartially, even with your own relatives and friends. Governing the country through both virtue and law will surely win the people's trust."
The king found this proposal quite reasonable and implemented it. Consequently, domestic order was quickly restored, and the state grew more stable and prosperous.
This story is the origin of the idiom "Love me, love my dog," which means that affection for someone extends to everything associated with that person.
