We arrived on Shanghai in September 23th, 2010. At first, I felt that it was very busy and dirty city. Shanghai is the largest city in China, it has improved since 1978 when the Chinese government started innovation. Nowadays, it has become the economic centre of the world.
I went to the Shanghai exposition. There were many kinds of pavilion, and very beautiful, exotic, and exiting performances were going on. The first impression I felt for Shanghai was dirty, but I felt the pavilions were very clean. But, unfortunately, I dropped my digital camera on the ground as soon as I arrived at Shanghai!
