Shanghai is awe-inspiring. Above is a picture of two of the largest buildings in the world. On the left is Shanghai World Financial Center, the second tallest in the world. On the right is Jin Mao tower. The latter has an observation deck on the 88th floor, where I went up. I couldn't see much, thanks to the clouds, but it was still an impressive experience. The last 30 floors is a hotel with an atrium you can look into.
Neither building is boring. They each have interesting architectural features. Jin Mao tower took an idea from ancient pagoda construction, with the decorative terraces all the way up.
When we went to the Yu gardens in the old town, we got glimpses of the Pudong skyline, which created an interesting contrast.
