My impression about Beijing, which greatly improved after the Beijing 2008 Olympic Games, uesd to be a chaotic and populous city.

I thought Beijing a noise and crowd city before, but I got a better feel after Olimpic Games was held.

In my eyes,Beijing is a noisy, with large population in the city in the past , but after my experience on the Olympic , I changed my view about Beijing a lot.
