Our new foreign students are going to arrive in Nankai very soon. They will stay with us for two weeks. Here are some ways to communicate with them properly.

How close do you stand when you talk to a friend? You can stand close to people in the Middle East but don't stand too close to North Americans! Give them more personal space.

Do you know how to touch(触碰)people? Chinese girls often walk arm in arm with their friends.

South Americans sometimes hold your arm when they talk to you, so you can't move away! But in Britain many people don't like other people to touch them at all.

Do you look at people when you talk? In some places, it isn't polite(有礼貌的) to look at people when you talk, but in other countries it isn't polite to look somewhere else. In Britain and the US, people usually look at each other when they talk.

And how do you say goodbye? That's easy, wave to say goodbye. But be careful! In Greece, it's not at all polite!
