Introduction to the Expo Center: The Expo Center is the operation command center, celebration and conference center, news center, and forum activity center of the 2010 World Expo. Located on the west side of the Expo axis and north of the Expo Theme Pavilion, the building is about 350 meters long from east to west and 140 meters wide from north to south. The layout of the building makes full use of the scenery along the river, and most functional spaces in the building have the best view of the landscape. Arranged at high and low levels from west to east, this is a green building in the true sense, a building full of wisdom. The World Expo Center is one of the five permanent buildings of the World Expo with one axis and four pavilions. It has now been transformed into a world-class conference center.
