Six renowned illustrators from across China gathered on the Metro Line 7 in Hangzhou, East China's Zhejiang province on Oct 17, and transformed the plain carriage into a space of color and fun. The activity was a warm-up for the 50 Years Bologna Illustration Master Exhibition, which is to open in the city on Nov 3, 2017. In line with the exhibition's theme of "guarding the dreams of children", the activity was organized in an attempt to bring more public attention to the wild dreams of today's children.
