On the morning of July 25, 2017, a construction worker starts a fog machine to spray atomized water at Changsha South Station Comprehensive Transportation Hub construction site. The China Construction Third Engineering Bureau Co., Ltd. has installed such facility at tower cranes and railings in major construction areas. It both effectively reduces dust and lowers the temperature, to create a refreshing environment for the workers. (Photo/Tian Chao)
