Since Wuhan was unsealed, it seems that the epidemic has eased recently, and we often see young people walking around without masks.
Maybe many people think that wearing a mask affects the appearance, breathing, discomfort and other reasons. If you really don't wear a mask to stroll in Sichuan, now it doesn't care about you, it's not compulsory and you have to do it.
In Japan, no matter who has a cold or cough, they will take the initiative to wear a mask. There is no mandatory requirement for you to wear a mask. Active and conscious behavior is a kind of civilization. Maybe the Japanese feel that coughing and catching a cold will bring trouble to others without a mask. Don't bring trouble and trouble to others, that's all.
In fact, many people have formed the habit of wearing masks. Wearing masks often has the following advantages:
1. Epidemic prevention
2. Prevent haze, dust, second-hand smoke, willow catkins, etc.
3. When taking the elevator or in public places, wearing a mask can reduce the bad smell of garlic.
4. Skin care, correction of face shape and appearance.
So, wear a mask, you still slowly develop a habit, normalization.
