Briefly describe the differences in greeting between China and the West.
【正确答案】：In China, people greeting with others with "Have you had your meal?" or "Where have you been?" They are very formulaic expressions. In the western countries, people will say: "How are you getting on?" or "How are things with you?" when they show their courtesy.
But when a Chinese talk to a Westerners the same sentence, the Westerners will be irritated, since these sentences invade their privacy, or these questions are predicable.
