Amazing city!!
Shanghai is a beautiful and amazing city. When getting of the Pudong airport I did see the city center, the high buildings are everywhere! when being close to the city you can't really see any skyline, because are buildings are tall. Very impressive city. Much cleaner then Beijing. Shanghai can offer you fantastic shopping, the bond is amazing at night with the view over Pudong. Many acitivities in the city parks, cosy places that one must see is the Old Town!
Insider Tip:Go to the Old Town early! and the Old Town park - which you'll need an extra ticket for is definitely worth the cost. Small, but very beautiful park, for people who appreciate the chinese architecture and nature.
