Wu Zetian’s terrifying ancient suggestion boxes

HERE’S THE INTERESTING PART

The ultimate ancient suggestion box, except the suggestions usually ended with someone getting brutally executed. Empress Wu, the only female monarch of China, set up literal copper drop-boxes so citizens could anonymously snitch on conspirators. If your neighbor annoyed you, you just dropped a note in the box, and Wu's terrifying secret police would handle the rest. HR departments could learn a lot.
