More than 240 countries and regions and around 70 million people participated in the world exposition.This was the first time for China to hold it, which made other countries know more about our country. The theme of the expo was "better city, better life". I had planed to visit it in the last summer vacation. However, I failed to go there as I didn't have enough time. Therefore I had to scan iton the Internet. The shape of each exhibition hall was bizarred, which left strong impression on me.The mascot of the expo was "treasure".There were tons of millions of volunteers working there during theexpo. Although I missed the chance to go there, it really made me memorable. The expo was hold in Shanghai during 2010/5/1 to 2010/10/31.
