my visit to 2010 shanghai world expo

About one week of this summer, my friend and I went to Shanghai to visit the expo. However, I was surprised that there are many people, who all come here for Expo. Actually, there are about 450000 visitors explore in the Expo every day.  I was astonished by this data.
Before I went to shanghai, my friend told me that it is hard to visit the Expo because the lines for visiting the China pavilion or the popular pavilions are so long, it takes long time to get in. Therefore, we should get up before 5:00 am and then rush into the subway at that time. I saw this crazy and crowded scene while stepped into the Expo. yard. Afterwards, I went into the Saudi Arabia Pavilion, I saw there were full of people, I lined up for 6 hours. I thought that was the craziest thing I did in my life, but it was worthy even though was 6 hours waiting. The pavilion impressed me so much.
After that, I continued to visit others, about 30 pavilions, including China, France, Italy ,United Arab Emirates, Denmark, Span ,Tortuga....... and many other urban best praceices, such as Madrid ,Bilbao ,Barceloma, Liverpool, London......... every pavilion takes me about 3 hours to queue before I get into. No matter what, I enjoyed this journey of Shanghai Expo; it widened my vision of the world and brought the new thoughts about the various cultures into my life.
