Beijing, formerly romanized as Peking, is the capital of the People's Republic of China, the world's second most populous city proper, and most populous capital city. The city, located in northern China, is governed as a direct-controlled municipality under the national government with 16 urban, suburban, and rural districts. Beijing Municipality is surrounded by Hebei Province with the exception of neighboring Tianjin Municipality to the southeast; together the three divisions form the Jingjinji metropolitan region and the national capital region of China.
As a city combining both modern and traditional architecture, Beijing is a megacity rich in history, exemplified in its global influence in politics, economy, education, history, culture, and technology. Beijing is the second largest Chinese city by urban population after Shanghai and is the nation's political, cultural, and educational center. It is home to the headquarters of most of China's largest state-owned companies and is a major hub for the national highway, expressway, railway, and high-speed rail networks.
