Children walk in an alley in Songji ancient town, Southwest China's Chongqing, May 22, 2015. The town, situated along the Yangtze River, was a bustling place in Ming (1368-1644) and Qing (1636-1912) dynasties due to the wharves here. As the railway and highway transportation developed in modern times, the town fell into decay, but the old buildings still remain. [Photo/Xinhua]
