The Chinese pavilion
An exciting experience
Two years ago, I went to Shanghai World Expo park. I had been looking forward to visiting that place for a long time.
I got up early that morning to catch the earliest bus. Before I left the hotel, I checked whether I had taken everything that I need in the Expo Park, such as the camera and the ticket. It was still early in the morning, but I could see people walking on the pavement, going to school or work. What a busy, fast-paced city!
Introduction
My way to the place
When I got there, there were lots of people who had arrived. When entering, I was given a map but I had a hard time reading the map. After a while, I got the hang of it. The time I saw so many wonderful pavilions, I cheered up. I like the Chinese pavilion best and it looked as if it were a palace floating in the sky, not on the earth. Now that I was there, I tried my best to see as many pavilions as I could. At last, I was exhausted but excited. The night fell, so I had to go back to the hotel.
What happened there
I stepped out of the Park, waiting for the bus. Luckily, it came immediately. I got on the bus and then I took out my camera to go through the pictures that I had taken. I had been to 10 pavilions in all and each one had its unique features. The trip was amazing and now I still look at the photos sometimes.
