Travelling around the world is many people's dream. It is a great way for people to see new places, meet new people and learn new cultures. However, you may have some trouble during the trip if you don't know the local customs(习俗)or the language. Some people would like to try using gestures to "talk with" the local people. That is to say, they tell others their thoughts by moving their hands or body parts.
Gestures are useful but every country is different in the way their people communicate with each other. So a gesture may be OK in one country but not OK in another.
Recently, a company has created a series of useful pictures of gestures around the world, hoping to help people understand different meanings of the gestures in different cultures and avoid making silly mistakes. Just take the "OK" sign for example. In China, we use it when we want to say everything is all right. However, in other countries such as Greece, Spain or Brazil, people see me "OK" sign as very rude. What's more, in some Middle East countries such as Kuwait, me sign stands for the evil(邪恶的) eye.
