"Don't be panic if houses are on fire, just put it out on time!" "Emergency kit should be kept in house." All those words are from some science popularity cartoons produced by Chenzhou Science Association. Recently, the cartoons were displayed on some public buses which are performed as special science trip buses in Chenzhou city. Over one million people/time can watch the cartoons every day.

In order to carry out the scientific popularity propaganda work and upgrade people's scientific quality, the implementation office of scientific quality action plan worked together with Chenzhou Bus Company and confirmed 18 public bus lines covering 253 buses as special scientific popularity lines to propagandizing science knowledge on the buses. Colorful cartoons with different themes will be displayed on the buses in turn, which would facilitate Chenzhou city with a new scientific popularity scenery.
