It borders Kaifeng to the northwest, Zhoukou to the southwest, and the provinces of Shandong and Anhui to the northeast and southeast respectively. An ancient city with a rich history, Shangqiu was also the first capital of the Shang dynasty. Its population was 7,362,975 inhabitants at the 2010 census whom 1,536,392 lived in the built-up area made up of Liangyuan and Suiyang districts.
