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 is a fascinating mix of East and West. It has historic shikumen (石库门）houses that blend the styles of Chinese houses with European design flair, and it has one of the richest collections of Art Deco buildings in the world. As there were so many concessions (designated districts) to Western powers during the turn of the 20th century, in many places the city has a cosmopolitan feel. There is everything from classic Parisian style, to Tudor style buildings that give an English flair and 1930s buildings reminiscent of New York or Chicago. There is a saying that goes, "Shanghai is heaven for the rich, hell for the poor," People from all over China flock to Shanghai — everyone from farmers seeking jobs in manual labour to university graduates seeking to start a career or wanting to live in a cool up-tempo city. Even well-off people, though, complain that buying a home is becoming impossible; prices have skyrocketed in the last few years.
