Kiss, the etiquette used by British and American people to express love, friendship, respect or admiration, has existed since ancient times. According to the custom of Britain and the United States, people of different identities kiss in different parts, between elders and juniors, on the face or forehead; Between peers, it is appropriate to cover; Husband and wife kiss their lips; Men can kiss the back of noble women's hands. However, it should be noted that although kissing is very popular in Britain and America, it is a very intimate greeting after all, so you should pay attention to the object and occasion when kissing, and you should not casually. Generally speaking, people who are not very familiar with each other should not kiss, otherwise it will cause surprise or embarrassment to each other; In addition, in a pure workplace (such as a conference room or office), it is generally not appropriate to kiss, but to shake hands. In addition, special attention should be paid to kissing between superiors and subordinates. Americans believe that kissing a subordinate boss will make people feel flattered; On the other hand, if a superior kisses a subordinate, it will make people feel that they have bad ideas about their subordinates by taking advantage of their position. Besides, kissing is not a necessary etiquette in greeting. If a person feels that he doesn't want to kiss each other, but he is worried that the other person will take the initiative to offer a kiss, he can reach out (shake hands) before the other person gets too close, smile and say "Nice to meet you" and so on, so as to avoid kissing that he thinks he doesn't want to.
