I met a friend on the street the day before yesterday, and I went over to greet him. As a result, the gentleman spoke to himself with a cigarette in his mouth, which made people feel impolite.

Generally speaking hello in the street, the three or four step is the best distance.

When greeting, a man may bow or nod, and if he wears a hat, he should pick it up.

It's impolite to hold a cigarette or put your hand in your pocket when greeting people.

When attending a meeting, you often greet some acquaintances, or meet some new friends. What is the general order of greeting?

Men should first greet the ladies. Young men and women should first greet the elderly, and the lower level should pay tribute to their superiors.

Two when the couple met, the women first greeted each other, then the men greeted each other's wives, and finally the men greeted each other.
