The Bund is the walk every Shanghainese takes their guests on. On one side, the granite buildings put up by banks, customs and big companies between the late nineteenth century and the 1930s, when Shanghai was Asia's financial hub; on the other, the Huangpu River and the skyscrapers of Pudong. You'll recognise the dome of the former HSBC bank, the clock tower of the Custom House and the green pyramid roof on the corner of Nanjing Road. Come early in the morning to see people exercising by the river, or at sunset, when the lights come on along both shores.
