Photo taken on Aug. 13, 2012 shows a section of the "Great Wall Under Water", which emerges out of the Panjiakou Reservoir in Kuancheng Manchu Autonomous County, north China's Hebei Province. The Xifengkou and Panjiakou Great Wall built in ancient China's Ming Dynasty (1368-1644) lied in the water following the building of the Panjiakou Reservoir in 1975. But sharp decline of the reservoir's water level because of drought brought it above the water this year. Recently, parts of the Great Wall, which emerged out of the water, were submerged again due to continuous heavy rain. [Xinhua/Zhu Jianjun]
