❍ 蛇咬一口，入骨三分，贼咬一口，跳下黄河洗不清…… (陈登科《活人塘》10) You may recover from a snake bite,but when you’re ‘bitten’ by scum like that,all the water in the Yellow River won’t wash you clean.
❍ 涛他娘插了一嘴，说： “跳到黄河里也洗不清。”(梁斌《红旗谱》141)“They couldn’t wash themselves clean,not if they jumped into the Yellow River，”continued Mrs Yan.
