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 arc 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.
