Zhangjiagang in East China's Jiangsu province held a public information campaign in an effort to promote World No Tobacco Day on May 30.

As part of the events on the day, Zhangjiagang residents took photos with "No Smoking" logos or slogans at booths and sent the photos to the internet by WeChat to call for the public to care about their health and to quit smoking if they do so.

World No Tobacco Day takes place on across the world every May 31, in order to get people pay more attention to the harms of smoking. The theme of this year is "Tobacco Breaks Hearts".
