Speaking from the other side of this issue... I generally advise all my students and non-English speaking friends to avoid swearing in English unless they're absolutely fluent.
Just in general, if you try cursing but you can't speak the rest of the language well, it creates the opposite effect of what you're going for--you end up looking like a fool who can't put two words together, so you have to revert to the one f-word you can manage to blurt out.
I have to say, whenever I've happened to have a non-English speaker try to curse in English but the rest of his/her words don't fit together quite right, I am more inclined to giggle than to take him/her seriously.
I suspect the same is true in Chinese and other languages. If you can't speak the rest of the language, don't try swearing. It comes out all wrong, and you sound like an idiot.
