truth will come to light sooner or later 纸包不住火

“纸包不住火”是一句俗语，比喻事实是掩盖不了的。这个表达的本意指火可以把纸燃烧，所以不可能把它包住。比喻事实是掩盖不了的。也形容某种形势不可阻挡。英语中可以用truth will come to light sooner or later；sooner or later, truth will out或者the facts will emerge sooner or later表示。

例句：

为了省那么点钱去钻法律的空子实在不值得，因为最终都会被发现的。

It's just not worth circumventing the law to save a little bit of money on your taxes, because the truth will out in the end.
