What is funny? The short answer is：who knows? The joke that causes a burst of laughter from one listener might be met with a puzzled look from another.
In general, you should avoid jokes at any business or social gathering where there are more than two people in your conversation group.If there are only two people — and they consist of you and your best friend—go ahead and tell it.
Admittedly, a few people possess a perfect sense of timing，appropriateness, and joke delivery. You are probably not one of them.You might be quite funny and have many great jokes.But there’s a place for jokes — over dinner with family or hiking with friends, but business or social affairs with colleagues and acquaintances (熟人) are not it.It takes a whole other level of joketelling ability to put a joke into the more formal conversations.
