A street floods after a heat supply pipe bursts in Zhengzhou City, the capital of Central China’s Henan Province, May 15, 2016. On the last day of the winter heat supply, local authorities tested the heat supply pipe network by increasing the pressure in order to identify and repair the weakest section, which will burst under the pressure.
