Different countries have different customs. When you travel to other countries, please respect their customs, just as the saying goes：When in Rome, do as the Romans do.

    Very often people who travel to the United States forget to tip (付小费). It is usual to tip those who help carry your bags, taxi drivers and waiters. Waiters expect to get a 15% tip on the cost of your meal. So do the taxi drivers.

    In England, make sure to stand in line even if there are only two of you. It's important to wait in line there. It's a good idea to talk about the weather. It's a favorite subject of a conversation with the British.

    In Spain (西班牙) , people have dinner very late and restaurants do not generally open until 9 p. m. It's a good idea to have a light meal in the afternoon if someone invites you for dinner. In this way, you may not feel too hungry at the table.

    In Japan, people usually give personal or business cards to each other when they meet for the first time. When a person gives you a card, don't put it into your pocket right away. The person expects you to read it.

    A kind of body language is acceptable in one culture, and maybe it is impolite in another. So don't forget to be careful of your body language to express something in a conversation.

    Sometimes business can take you out of your home country. That means you have to communicate with people from other cultures. So it's important to1some international customs. Here are some special2customs.

    In France, if you don't speak French, that's OK, but you are3to say sorry for you can't communicate easily first. If you don't have time to learn French before doing business there, learning a few phrases or greetings can serve as a4of good faith (诚意). Also, be prepared for5meals in France. Lunch can last up to two hours long.

    Change your6to a little earlier when doing business in Australia. Being on time is very important when meeting to discuss business. If you're not going to be7on time, then you should arrive a bit early. It's quite impolite to be late.

    While the business8hasn't been so important in the US, that is far from the9in Japan. When doing business with the Japanese, you should carry lots of business cards, which should be printed in both English and 10. The business card is held in very high regard in Japan. When giving your cards to others, you must pass them out11both hands, with the Japanese side facing up. When receiving a business card, you should accept12with both hands.13, the business card should never be written on or played with during the meeting, as both are signs of disrespect.

    Left-handers (左撇子) may have some14doing business in the United Arab Emirates. In Middle Eastern countries, the left hand is considered15. It is important to eat, shake hands and pass things with the right hand only. Using the left hand to do any of those activities is a serious insult (侮辱) .
