Expo construction on track

With 79 days to go before the 2010 Shanghai Expo, much of the construction is now complete. The steel structure is finished on 18 of the 31 Chinese pavilions, including Beijing's.

The Beijing pavilion has been nicknamed "the transformer", because it can change its shape.

Xu Yuwei, Director of Beijing Coordinating Office, said, "To demonstrate the changing nature of the capital, the pavilion will change its appearance to represent the Bird's Nest, the Water Cube, the National Theatre and the Temple of Heaven."
