Shanghai
Shanghai is at the mouth of the Yangtze River, where it meets the East China Sea in the middle of China's east coast. Downtown Shanghai is located just south of the place where Suzhou Creek meets the Huangpu River. This is about  southwest of where the Huangpu meets the Yangtze River. The area between downtown and the Yangtze used to be farmland and other cities like Wusong and Baoshan, but now Shanghai is so big that they are part of it.
