Huge mist cannons attract people in Lanzhou (3/3)

People take an interest in huge mist cannons at the Dongfanghong Square in Lanzhou, Gansu province on Sunday, May 4, 2014. The industrial water cannons are designed to spray mist to the air to control dust. They were placed at the square to water the lawn because the sprinkling irrigation system there could not work due to subway construction activities. (Photo: China News Service/Yang Yanmin)
