With plenty of aquatic plants dotting the Han River in Wuhan section, the water has turned completely green. When the floodgates of the dam are opened, these plants flush down from the upper stream and pile up here.

　　The aquatic green plants float over the river under Yuehu Bridge in Wuhan city, south China's Hubeiprovince, on July 7, 2014. The accumulated plants turn the water green and make the effort to clean the river an impossible task.(Source: china daily/IC)
