Don’t wash your dirty linen in public.
家丑不可外扬。
Certain things should only be done in certain places. This is especially so when they concern matters that are embarrassing, shameful, or intimate. The saying, “Don’t wash your dirty linen in public,” specifically tells us that we should not discuss intimate family matters in public, especially if they are of a shameful nature.
有些事情只应在特定的场合做。尤其是关系到令人困窘、不名誉或亲密的事情更应如此。俗云:“家丑不可外扬”,它明确地提醒我们不应在公众场合讨论私人的家务事,特别是如果那些事本来就不是很光彩的话。
