A flash mob forms in a Metro train car Sunday, the launch day of six themed trains promoting scientific knowledge. The Shenzhen University of Advanced Technology and Guangming Science City have jointly introduced these special trains on Metro lines 4 and 6. Operating until July 18, the initiative aims to bring cutting-edge scientific knowledge to the public. The six train cars showcase different scientific themes and achievements from the university’s seven colleges. Some also feature interactive quizzes in fields such as pharmacology, biotechnology, and neuroscience. Courtesy of the university
