Wūhǎi is a prefecture-level city and regional center in the Inner Mongolia Autonomous Region of the People's Republic of China. It is located on the Huang He between the Gobi and Ordos deserts. Wuhai became a single city occupying both banks of the Huang He river with the amalgamation on 1976 of left-bank (west) Uda (then administrated by Bayan Nuur League) together with Haibowan on the right (east) bank (then administrated by Ikh Juu league). Wuhai is one of very few cities with an antipode which is not only on land (as opposed to open ocean), but which is another inhabited city; the antipode of Wuhai is almost exactly on the city of Valdivia, Chile.
