1.平时不做亏心事，夜半敲门心不惊。
A clear conscience can bear any trouble.
2.一朝被蛇咬，十年怕井绳。
A burnt child dreads the fire.
3.明枪易躲，暗箭难防。
etter the devil you know than the devil you don't know.
4.人不为己，天诛地灭。
Every man for himself， and the devil take the hindmost.
5.一失足成千古恨，再回首已百年身。
A little neglect may breed great mischief.
