How to effectively avoid the harm of "secondhand smoke"?

I haven't been harmed by secondhand smoke since I went to work. I don't smoke myself, and my colleagues around me smoke a lot, but they don't have a chance to smoke.

Let me tell you how to avoid the harm of second-hand smoke. In fact, the best way is to choose a high-end working environment. For example, smoking is prohibited in most high-end office buildings in Beishangguang. Some buildings may have smoking rooms, or smoking is allowed on the terrace, but most office buildings are absolutely forbidden from entering the building. Once someone smokes secretly or even hides in the toilet, it will trigger the corresponding alarm. This is because this office building is so multi-storey and densely populated, and the requirements for fire prevention and safety are higher.

To ensure foolproof, the management of such dangers as cigarette butts is stricter. In Shanghai, there are few offices and restaurants where smoking is allowed. If you go to the fourth-and fifth-tier cities or some small companies, the ashtray in the office is a necessary office supply, and their parties are mainly for smoking and drinking.

In Hong Kong, smoking is forbidden in most public places. If you find smoking, you will face a large fine, so everyone is even more afraid to try the law. When you go to the countryside at ordinary times, even if you don't smoke or pass cigarettes to others, you will be considered stingy. This person will not be a man.

So, what I want to say is, how to avoid the harm of second-hand smoke? That is, try to find some higher environment, in which people really don't smoke or are not allowed to smoke.

It's hard to change a person's behavior and habits. Don't try to persuade others to give up smoking. This is the advice of a bad person. You will never understand smokers' love for cigarettes, so I avoid talking about it.
