Architect: Christian de Bauzambach (Pritzker Prize-winning)

Unlike the square box of modernism, the architect designed a long "streamer" shaped like a "ꝏ", which wraps around from one wing of the top of the building to the other side, then passes through the facade to reach the height above the ground. It is 40 meters away from the crosswalk, forming a visual opening area leading to the lake. The two high and low steel structure ribbons are intertwined to form a very iconic architectural feature, which is both the roof of the Grand Theater and the side wall of the Expo Center.

The innovative structure and curtain wall integrated design won two championships in China: the maximum span of the high-level "streamer" is 100 meters, and the length of the low-level "streamer" is 370 meters
