Different people will have different ideas about Shanghai Expo. Some people like the colorful cultures, other people like many kinds of building styles, and so on. We can see many articles on the internet. In my point of view, I like very much the ideas which Shanghai Expo conveys to us.

First, Shanghai Expo shows us many different city lives in different countries. Whichever city you are in, you will have different life style totally, because different cities will produce different resources for you, such as public transportation system, building, catering, etc. If you choose one city, you will choose one city life.

Second, Shanghai Expo shows us another side of our city which we always ignored. Our cities develop very quickly. The more cities, the more demands for our cities. At the same time, there are many farm pollutants, industry pollutants and life pollutants, etc. We will be aware of seriousness which the situation will cause in City Earth Pavilion.

Third, Shanghai Expo shows us how we can change for our better lives. If we change a little everyday, our city will become more beautiful in the future. It gives us more and more examples in some pavilions. Low-carbon life style is the most important idea which Shanghai Expo shows to us. But it is not enough, we not only should know about it, but also should do it as soon as possible from now.

Finally, Shanghai Expo is the window which we can know and learn from other countries, such as foreign culture, high technology and life style and so on.

It is not doubtful that Shanghai Expo will have more positive effects on Yangtse Delta Areas, especially on Shangahai. I best wish Shanghai Expo will have a bright and successful holding in China.
