The outbreak isn't over yet - we can't get complacent.
Tips
usage
Strongly critical. Used in safety, security, and public-health contexts to warn against complacency. Standard collocation: 不能 / 切勿 / 切忌 + 麻痹大意.
memory
麻痹 originally 'paralysis / numbness' - the body's senses go offline. Extended to mental numbness: a mind that fails to notice danger. 大意 = 'careless'. Numb + careless = guard completely down.
