Is the site built for the Expo an open space or has it been demolished? Will these pavilions stay after the meeting? Do foreign libraries withdraw materials?

It turns out that both sides of Pujiang are industrial enterprises, and the pollution is not light. They moved away through the World Expo, including famous old enterprises such as Jiangnan Shipbuilding. Improve the ecological environment on both sides of Pujiang and adjust the land use structure through the World Expo. After the World Expo, China Pavilion, Theme Pavilion, Expo Center, Expo Performing Arts Center and Expo Axis were all preserved and became permanent buildings. All the other pavilions have been demolished. Some pavilions will return to their own countries for reconstruction. The theme of this World Expo will be the harmonious development of cities, ecology and people, because many Expo buildings emphasize green, environmental protection and high technology, and the exterior wall materials of some pavilions are degradable or reusable.
