Chinatown occupies a really big part of the city, in fact it is the biggest Chinese community all over the America. It settled during the 1850's. Here you can see the busy life that enliven its streets. Passing through the main gate you simply jump into another world where shop, food, goods and people speak China. New York as well has its own Chinatown New York.
