Although in China there are no fixed rules for greeting one another, physical contact is much less common than in Europe. Only a small, though increasing, minority of young people hug or kiss their closest friends. Shaking hands has become a broadly accepted gesture in the great metropolises, but still by far not as widespread as in Europe.
The commonest and most neutral greeting are a polite ''ni hao'' and a slight nod of the head. Contrary to the Japanese, Chinese do not make deep bows.
Good bye.See you later.
The phrase ''Ni Hao'' is a very practical one, since it can be used at any time of the day or night.
