Whistle-blowers

Julie Ebell (right), a tourist from the United States, blows a whistle installed on a kite under the instruction of Guo Chengyi, a craftsman, in Nantong, Jiangsu province, on Sunday. This type of kite can carry more than 100 whistles and can produce different sounds with the change of wind speed as it flies in the sky. Photo by Xu Congjun / for China Daily
