With only 117 days to go before the world fair opens, most pavilions at the Expo site have been completed or are nearly finished.

The Expo center and the Theme Pavilion have celebrated their completion, while construction on the other permanent structures - the China Pavilion, Expo Boulevard and Expo Performance Center - will soon be finished.

About 70 percent of the 42 self-built pavilions have started interior decoration and exhibition arrangements, which are expected to be finished by the end of March.
