     Handshaking, though a European practice, is now often seen in big cities of China. Nobody knows exactly

when the practice started in Europe. It is said that long long ago in Europe when people met, they showed their

unarmed (无武器的) hands to each other as a sign of goodwill. As time went on and trade in cities grew

rapidly, people in cities began to clap each other' s hands to make a deal or to reach an agreement. This practice was later changed into shaking hands among friends on meeting or leaving each other."Let' s shake (hands) on

it" sometimes means agreement reached.

     Do the Europeans shake hands wherever they go and with whomever they meet? No. Sometimes the

Chinese abroad reach out their hands too often to be polite. It is really very impolite to give your hand when the

other party, especially when it is a woman, shows little interest in shaking hands with you and when the meeting does not mean anything to him or her. Even if, for politeness, he holds out his unwilling hand in answer to your uninvited hand, just touch it slightly. There is generally a misunderstanding (误解) among the Chinese that

westerners are usually open and straightforward, while the Chinese are rather reserved (保守的) in manner. But

in fact some people in western countries are more reserved than some Chinese today. So it is a good idea to

shake hands with a westerner only when he shows interest in further relations with you.
