In fact, the kissing ceremony was circulated in ancient Rome. At that time, women were not allowed to drink. When a man comes back from going out, he will check whether his wife has been drinking that day and will smell it around her mouth. Later, the act of couples putting their mouths together gradually became the first etiquette when they met, and gradually became popular, and finally evolved into a kissing ceremony in western countries today.
Kissing hands is still very popular in western countries. When men meet aristocratic women in the upper class, if women reach out and make a drooping gesture first, men can gently lift their fingertips and kiss. But if the woman does not reach out, she can't kiss. If the woman's position is higher, the man should bend one knee, make a gesture of half kneeling, and then hold hands and kiss. Kissing hands is very popular in England and France.
But deep kissing is very popular in France, but it is not characteristic of France. As a way of expressing love, deep kiss has a unique expression all over the world. In fact, among European kissers, the French are obviously in the highest position and the British are at the bottom, but the status of Britain and France in history is another era. It is hard to imagine that the inaccessible British who are not very fond of expressing their feelings in this century have become internationally famous for their social behavior.
