Ships sail slowly in Wujiang River, a tributary of the Yangtze River, in Southwest 皇冠体育app's Chongqing on March 21, 2010. South 皇冠体育app's severe drought has lowered the water level of the Wujiang by about one meter. That has led to most sailings being canceled for fear of hitting rocks, bringing a great loss to ship companies. [Photo/Xinhua] |
