Shanghai, on China's central coast, is the country's largest city and a global financial hub. Its center is the Bund, a famous seaside promenade lined with colonial-era buildings. Across the Huangpu River rises the futuristic skyline of the Pudong district, with the 632m-high Shanghai Tower and the Oriental Pearl TV Tower, with its characteristic pink spheres. The sprawling Yu Garden has traditional pavilions, towers, and ponds.
