What do you do to entertain your foreign friends？Why？

At first you must make sure where your foreign friends are from.
Because the people come from different areas of the world have different customs 、traditions、religions and taboos.
Do not make them violating their taboos,you can do some recreations with your foreign friends which they like in common,just like playing sports、the delicious food of China and etc.
I think they also would give you some advices.
According to my suggestions , they must be very happy.
