Harbin is the capital and largest city of Heilongjiang province in China's northeast region, as well as the tenth most populous city nationally. According to the 2010 census, the city's urban area has 5,878,939 inhabitants, while the total population of the sub-provincial city is up to 10,635,971. Harbin serves as a key political, economic, scientific, cultural and communications hub in Northeast China. Harbin, which was originally a Manchu word meaning "a place for drying fishing nets", grew from a small rural settlement on the Songhua River to become one of the largest cities in the northeast. The city first prospered as a region inhabited by an overwhelming majority of the immigrants from the Russian Empire. It is known for its bitterly cold winters and is often called the "Ice City." Harbin is notable for its beautiful ice sculptures in winter and its Russian legacy, and it still plays an important part in Sino-Russian trade today. In the 1920s, the city was considered China's fashion capital since new designs from Paris and Moscow reached there first before arriving in Shanghai. In 2010, Harbin was declared a UNESCO "City of Music".
