On November 28, 2020, CCTV13 Heard from the World, the interview was about when to ban smoking on ordinary trains? Is the existence of smoking areas on trains really reasonable? The interview was conducted with Associate Professor Gu Dasong of our college.

The host pointed out that smoking is banned in general speed trains, but smoking is allowed in the connections of the cars, and the trains are not effective in blocking the spread of smoke to the cars, so non-smoking passengers are still inhaling second-hand smoke. In the public places have been a total ban on smoking now, the general train why there are still smoking areas or smoking out area?

Associate Professor Gu Dasong believes that many people's smoking behavior now affects public health, high-speed trains have similar provisions on the smoking ban, the relevant authorities can improve the relevant laws and strengthen law enforcement to promote the implementation of the smoking ban.
