When you smoke, you either smoke yourself or you have to circle. This is called "smoke never falls on people". Whether others smoke or not, you should smoke for others.
When smoking, either open the cigarette case for others to take, or you can take the lower part for others to smoke, not the filter tip. Don't talk to others with a cigarette in your mouth, don't spit on others, and don't dance too much with your hand holding a cigarette so as not to burn others. Go to the leadership office or someone else's house. If the owner doesn't smoke, don't take the initiative to smoke. Try not to smoke.
Etiquette of "seven don't pick up" cigarettes
First, don't pick up the first cigarette in the cigarette case.
Second, don't pick up the last cigarette in the cigarette case.
Third, don't pick up the cigarettes inserted backwards in the cigarette case. It is the owner's "wishing cigarette", which is reserved for himself to smoke at last. If you take it away, you take away good luck.
The fourth is to give it to others first, and don't pick up cigarettes that others don't want.
Fifth, if someone gives it to him, don't pick up the cigarettes he gives you.
Sixth, look at other people's faces, and don't pick up the cigarettes sent to you.
Seventh, don't accept bargaining cigarettes.
