E-cigarette smoking is becoming more popular among Chinese middle school students as the proportion of e-cigarettes smokers had increased significantly in 2019, according to a survey published on the 33rd World No Tobacco Day (WNTD) on Sunday, which was also one day before the fifth anniversary of China's capital Beijing banning public smoking. 

Experts, who widely promote quitting smoking, called on the public to protect young people from traditional tobacco products and e-cigarettes, which is also the theme of the 33rd WNTD.
