My name is Li Hua. During the summer holiday, I worked as a volunteer in the World Expo 2010 in Shanghai.
During these days, I worked very hard. I was very happy to help the tourists. I met many new friends. Many of them were from foreign countries. So I practiced my oral English. At the same time, I also developed my team spirit and the sense of duty.
I felt very proud that I can do something for the world exposition and I am also proud of our country. It was really a very meaningful holiday.
