A flash mob of 35 young officers from the Zhangjiagang municipal transport bureau gathered at the city's landmark areas on April 15 to advocate good manners and eco-friendly ways of travelling.

At the crowded pedestrian street, shopping mall, and coach station, the youngsters put on a variety of performances, such as a shuffle dance, queue exercises, and short plays, showing the residents a vigorous image of port city officers, as well encouraging them to join in green and well-mannered ways of travelling.

Not only locals but also tourists marveled at the attractive shows, which they recognized as very professional and added a unique aspect to Zhangjiagang's fame as a national civilized city.
