The poor and the rich form the main force of 300 million Chinese smokers; what they are smoking is not cigarettes, but anxiety -- University Student Success Network

The poor and the rich are the main groups among China's 300 million smokers.

The number of smokers somehow represents the happiness index of a country. In a sense, when they smoke, they are puffing out their anxieties.

In the first half of 2010, under the assistance of the World Health Organization (WHO), the Chinese Center for Disease Control and Prevention organized an investigation on the smoking population in China.
