"The city of Shanghai sits along the delta banks of the Yangtze River along the eastern coast of China. The city proper is the world’s most populous city (the 2010 census counts 23 million people, including “unregistered” residents). With that many humans, the city is a tremendous sight at night. Shanghai is a key financial capital for China and the Asian Pacific region. The bright lights of the city center and the distinctive new skyscrapers that form the skyline along the Pudong district (the eastern shore of the Huangpu River, a tributary of the Yangtze that cuts through the center of Shanghai) make for spectacular night viewing both on the ground and from space."
