The Chinese have a peculiar way of doing things.
Regardless of the dialect, as long as a curse word like "cao ni ma" (fuck your mother) is delivered with the right intensity, everyone gets the gist, even if they don't understand the specific words. That is, unless you’re dealing with one of those nasty types who smiles while swearing and gives you a thumbs-up.
"Let’s go with this line... it’ll be easier to get past the censors. 'Cao ni ma' is just too blunt."
