白日不做亏心事,半夜敲门心不惊 meaning in Chinese

One who hasn't done anything against conscience during the day needs not to be scared by the knocks at the door at midnight.A quiet conscience sleeps in the midst of thunder.A good conscience is a soft pillow.A clear conscience is a sure card.A clear conscience laughs at false accusations.A clear hand wants no washing.A good conscience is a constant feast.
