Tips

history
Recorded in Wu Jianren's 《二十目睹现状》 (late Qing): visitors arrive at a government office to find soldiers stationed everywhere, the place 'as if facing a great enemy'. Captures the bureaucratic-paranoid atmosphere precisely.
usage
Often slightly mocking — implies the precautions are excessive for the actual threat. Use it to point out overreaction as well as legitimate high alert.
