Shanghai (上海 Shànghǎi) , with a population of more than 23 million (with over 9 million migrants), is the largest and traditionally the most developed metropolis in Mainland China.Shanghai was the largest and most prosperous city in the Far East during the 1930s.In the past 20 years it has again become an attractive city for tourists from all over the world.
Shanghai is split in two by the Huangpu River (黄浦江 Huángpǔ Jiāng).
The most basic division of the area is Puxi (浦西 Pǔxī) West of the river, versus Pudong (浦东 Pǔdōng), East of the river.
Both terms can be used in a general sense for everything on their side of the river, but are often used in a much narrower sense where Puxi is the older (since the 19th century) central part of the city and Pudong the mass of new high-rise development across the river since the 1980s.
The Bund (外滩 Wàitān) The colonial riverside of old Shanghai, has dozens of historical buildings lining the Huangpu River, which once housed numerous foreign banks and trading houses.
The commercial district of West Nanjing Road extends from the middle of Jing'an to People's Square.
Old City (南市; Nanshi) Home of Yu Garden, the City God Temple and Huxingting Tea House, this is the historic Chinese area of the city, where much of the old wooden architecture of ancient Shanghai is still preserved.
Zhabei (闸北区; Zháběiqū) Zhabei is an older district of Shanghai and the location of the Shanghai Railway Station.
There is a large park, Daning-Lingshi, north of the station, as well as the Shanghai Circus.
The riverfront walkway has recently undergone a major reconstruction and reopened to the public in March 2010.
