Beijing, as the capital and one of the four municipalities of the People's Republic of China (PRC), is a transport hub, with a sophisticated network of roads, railways and two major airports. Five completed ring roads encircle the city with nine expressways heading in virtually all compass directions, supplemented by eleven China National Highways.

Beijing, alternatively romanized as Peking, is the capital of China. With more than 22 million residents, Beijing is the world's most populous national capital city as well as China's second largest city after Shanghai. It is located in Northern China, and is governed as a municipality under the direct administration of the State Council with 16 urban, suburban, and rural districts. Beijing is mostly surrounded by Hebei Province with the exception of neighboring Tianjin to the southeast; together, the three divisions form the Jingjinji megalopolis and the national capital region of China.
