Qin State.
Government Office.
The Injustice Drum at the entrance of the government office was struck, emitting a series of dull sounds, alarming the officials inside, sparking a commotion in each office.
"What's happening?"
"Who's beating the drum outside?"
"Law Officer Zhou, go check immediately, don't let him keep striking it!"
"Damn it, are the Government Officials at the door slacking off again? Why aren't they stopping it?"
...
Though the Injustice Drum is meant for people to seek justice, its main function is to make the public and the court believe it's for seeking justice; who would be so fearless as to dare strike that thing?
The number of times the Injustice Drum is struck each year is assessed in the performance evaluations of local officials; the more strikes, the more wrongful cases in the jurisdiction, affecting their assessment. If people come seeking justice every day, what then?
