Dai Liu, president of Shanghai World Expo Co., said, "Because of the way the brackets interlock, the structure will not loosen as time passes by. Contrarily, they will interlock increasingly firmly. This feature appropriately symbolizes a union and harmony."

Another classical highlight of the complex is captured in the Fold Zhuan Calligraphy, which is being used to write the names of all local participants on the regional pavilion walls. Walls, which are designed to save energy.

Professor Zhang Li, Tsinghua University, said, "Passive energy-saving technology means we design the building in such a way that it can act as a sunshine shelter, or reflects the sunshine or controls the air circulation, so that little energy is used."

People of Shanghai have been working on the China Pavilion for more than 16 months now. As we can see the concrete and steel frame has already been completed. Workers are now busy with the interior decoration, and all the work is to be finished before the end of the year.
