May I smoke in Beijing Hotel?

You can't. Smoking is prohibited in hotels in Beijing. There is a smoke alarm system in the room. If you smoke, it will trigger the smoke alarm. The ventilation system in the hotel has been connected. Therefore, if guests smoke in the room, they will not only store secondhand smoke and third-hand smoke in their own room, but also pollute other rooms through the air conditioning system. So smoking is not allowed in hotels in Beijing.
