In China, burping or farting after eating is considered to be very rude. It's like something you'd do as a joke - but not in companies. In England we could just boil it and let the gas out faster... But then again, we're going to go back to China. We're glad that we are discreet about those things at the same time. Fpart? Fair enough. How many of you can actually kill yourself with one farts? If you fart and burp at the sametime you can die inside. And then what happens? You implode.
