There are some points which are particularly important to remember when we are doing business with the Japanese. First of all, age is a very important factor. Japanese managers, for instance, are much older than American managers. So many American companies fail in doing business with the Japanese by sending men far too young to conduct business negotiations (谈判) in Japan with their Japanese counterparts, who could be their fathers! It is quite an insult to the Japanese.The next point to be remembered is the use of business cards. The business card is not a simple piece of paper in Japan. Every business encounter starts with the exchange of business cards. The business card represents the person himself. You should receive it and study it with great care, when it is given to you. The first thing you should do as soon as you've arrived in Japan is to have 200 business cards printed for yourself.The last point I want to draw your attention to is about business meetings or negotiations. First of all, don't talk too much. Japan's culture is essentially a non-verbal one. And don't expect the Japanese businessmen to answer you with a clear "yes" or "no". It often takes a long time to make a decision, or to arrive at a solution.What do we know about business cards in Japan?(2分)A People have different business cards.B businessmen have about 200 business cards.C The business card is a simple piece of paper.D People take business cards seriously.
