Shanghai (Chinese: 上海; pinyin: ShànghÇŽi) is a metropolis in eastern China, and a direct-controlled municipality of the People's Republic of China. Located at the middle part of the coast of mainland China, it sits at the mouth of the Yangtze.
Originally a fishing and textiles town, Shanghai grew to importance in the 19th century due to its favorable port location and as one of the cities opened to foreign trade by the 1842 Treaty of Nanking. The city flourished as a center of commerce between east and west, and became a multinational hub of finance and business by the 1930s. After 1990, the economic reforms introduced by Deng Xiaoping resulted in intense re-development and financing in Shanghai, and in 2005 Shanghai became the world's largest cargo port.
The city is a tourist destination renowned for its historical landmarks such as the Bund and City God Temple, and its modern and ever-expanding Pudong skyline including the Oriental Pearl Tower. Today, Shanghai is the largest center of commerce and finance in mainland China, and has been described as the "showpiece" of the world's fastest-growing major economy.
The population of Shanghai is 19,213,200. Based on total administrative area population, Shanghai is the third largest of the four direct-controlled municipalities of the People's Republic of China, after Chongqing and Beijing. In the PRC, a direct-controlled municipality (直辖市 in pinyin: zhíxiáshì) is a city with equal status to a province.

According to the Shanghai Municipal Statistics Bureau, there were 133,340 foreigners in Shanghai in 2007. Some foreign expatriates are staying in Shanghai as long-term settlers, renewing Shanghai's reputation as China's global city. In addition, there are a large number of people from Taiwan for business (estimates vary from 350,000 to 700,000).
