What is the source of China Pavilion's creativity in Expo design?

He Jingtang, Chief Designer of China Pavilion: The design of the national pavilion and the regional pavilion embodies the traditional concept of "harmony between man and nature" in China. Structurally, China Pavilion consists of National Pavilion, Regional Pavilion and Hong Kong, Macao and Taiwan Pavilion, in which the National Pavilion rises in the center like a canopy, and the Regional Pavilion is horizontally located under the National Pavilion, providing a lot of activities and exhibition space. The final architectural form of the National Pavilion resembles a traditional architectural component in ancient China-the bucket arch, but some people think it is like an official hat, also known as the "crown of the East". I prefer to think of it as a granary, which means "granary in the world, rich people"
