Beijing.

Beijing, China's capital, is a large city located in northern China. It is considered a direct-controlled municipality and as such it is controlled directly by China's central government instead of a province. Divided into 16 urban and suburban districts and two rural counties, Beijing has a very large population of 22,000,000 and it is known as being one of the Four Great Ancient Capitals of China, along with Nanjing, Luoyang and Chang'an or Xi'an. It is also a major transportation hub, a political and cultural center of China and was host to the 2008 Summer Olympic Games. The name Beijing means Northern Capital but it has been renamed several times in its history. Some of these names include Zhongdu (during the Jin Dynasty) and Dadu (under the Yuan Dynasty). The city's name was also switched from Beijing to Beiping (meaning Northern Peace) twice in its history. After the founding of the People's Republic of China however, its name officially became Beijing.
