In what places has smoking already been banned in China?Are you in favor of this policy or not?

Nowadays in China,smoking is banned in many public places,such as cinemas, threators, supermarkets, hospitals, meeting rooms and sooon. As far as I am concerned, I am strongly in favor of this policy. First of all,smoking is bad for health.And in public places it often leads to second-hand smoking, which is bad for the smoker as well as people around. Second, if you are talking with a person while you are smoking, what will happen?He or she will consider the necessity of whether to go on talking or not, because your behavior shows that you don’t care much about what you are talking.Smoking makes you lose friends.Third, smoking costs lots of money, which will result in quarrels and tight budget at home. That’s not good for building up of a harmoniouss ociety.Thus,I am strongly in favor of this policy.
