Beijing, sometimes romanized as Peking, is the capital of the People's Republic of China and one of the most populous cities in the world. The population as of 2013 was 21,150,000, and has a permanent resident population of 19,612,000. The metropolis, located in northern China, is governed as a direct-controlled municipality under the national government, with 14 urban and suburban districts and two rural counties. Beijing Municipality is surrounded by Hebei Province with the exception of neighboring Tianjin Municipality to the southeast.

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. The Beijing Capital International Airport is the second busiest in the world by passenger traffic.

The city's history dates back three millennia. As the last of the Four Great Ancient Capitals of China, Beijing has been the political center of the country for much of the past eight centuries. The city is renowned for its opulent palaces, temples, parks and gardens, tombs, walls and gates, and its art treasures and universities have made it a center of culture and art in China. Encyclopedia Britannica notes that "few cities in the world have served for so long as the political headquarters and cultural centre of an area as immense as China."
  
Etymology
Over the past 3,000 years, the city of Beijing has had numerous other names. The name Beijing, which means "Northern Capital" (from the Chinese characters 北 for north and 京 for capital), was applied to the city in 1403 during the Ming Dynasty to distinguish the city from Nanjing (the "Southern Capital"). The English spelling is based on the pinyin romanization of the two characters as they are pronounced in Standard Mandarin. An older English spelling, Peking, is the Postal Map Romanization of the same two characters as they are pronounced in Chinese dialects spoken in the southern port towns first visited by European traders and missionaries. Those dialects preserve the Middle Chinese pronunciation of 京 as kjaeng, prior to a phonetic shift in the northern dialects to the modern pronunciation.

The single Chinese character abbreviation for Beijing is 京, which appears on automobile license plates in the city. The official Latin alphabet abbreviation for Beijing is "BJ".
