Shanghai is the country's biggest city and a global financial hub. Its heart is the Bund (Wai Tan), a famed waterfront promenade lined with colonial-era buildings. It offers many exciting sightseeing. We also visited Nanjing Road (Nánjīng Lù), Shanghai's principal shopping street, lots of shops there. It depends on which month you go there. Summer time again is very hot but during winter and early spring time is very cold there. The only time we can go there is either summer or winter season due kids in school but if you go durning summer time is very crowded because the school there is on break too.
