The idea is that pigs sweat a lot;they may or may not, but that's the expression.

这个想法是猪出汗很多； 他们可能会也可能不会，但这就是表达方式。

I mean you will never catch me doing that. But, I have seen you sweating. Well, I guess so. Ever seen a pig do that? Have I seen a pig sweat? Well, I guess not. But what's your point?

我意思是，你怎么也不可能看到我会那样做。 但是，我看过你流汗。 好吧，我承认。 看过一只猪那样过吗？ 我有没有看过猪流汗？我想没有。但你想说什么呢？
