Shanghai Corporate Joint Pavilion at the west part of the Shanghai World Expo site is illuminated on April 26, 2010 in Shanghai, east China.

Shanghai Corporate Joint Pavilion at the west part of the Shanghai World Expo site was illuminated yesterday.

The pavilion is an eco-building with intelligent technologies, dream-like atmospheres, and interactive experiences.

The architectural design concept is originated from the Taoist theory "A harmonious combination of heaven, earth and man" and "Zhuang Zhou's dream with butterfly," an ancient Chinese romantic story with philosophical meanings.

The pavilion provides visitors with a 17-minute interactive experience in four different zones - Sound of the City, Close to the Huangpu River, Road of Shanghai and Travel to the Future. Using pictures and music, visitors will be encouraged to think about how to make the city's future better.
