     Different countries and different people have different manners.We must find out their  customs so that

they will not think us ill-mannered(没有礼貌的). Here are examples of the things that a person with good education does or does not do.

     If  you  visit a  Chinese  family, you  should knock at the door first. When the door opens, you will not

move before the host says" Come in, please." After you come into the room, you would not sit down until

the host asks you to take a seat. When a cup of tea is put on a table before you or sent to your hand, you will say "thank you" and receive it with two hands, not one hand or they will  think you are ill  -  mannered.

Before entering a house in Japan, it is a good manner to take off your shoes. In  European countries, even

though shoes sometimes become very dirty, this is not done. In a Malay house, a  visitor never finishes the

food on  the  table. He leaves a little to  show that he has had enough. In England, a visitor always finishes

the drink or the food to show he has enjoyed it. That will make the host pleasant.
