Chongqing - Megacity and provincial-level municipality in southwest China

"Chongqing, alternately romanised Chungking, is a megacity in southwest China. Administratively, it is one of the four municipalities under the direct administration of central government of the People's Republic of China, and the only such municipality located far away from the coast. The municipality of Chongqing, which is around the size of Austria, includes the city of Chongqing and various non-connected cities. As the Chongqing municipality government directly administers the city of Chongqing, as well as rural counties, and other cities not connected to the city of Chongqing, Chongqing municipality can technically claim to be the largest city proper in the world, even though this is due to a classification technicality and not because it is actually the world's largest urban area. - Wikipedia"
