People who smoke on the balcony should only consider that there are children at home or their families are not allowed to smoke indoors, so smoking on the balcony, smoking in the bedroom has an impact on others, and smoking on the balcony is ok.
But if it is a closed balcony, it is not recommended to smoke on the balcony, or open the window of the closed balcony to smoke. Otherwise, cigarette tickets will arrive at home and affect the health of family members.
