Introduction to architectural features: After the completion of the New National Expo, the architectural features of “two axes and one area” were formed. "Two axes" means that after the audience enters the museum from the west gate, they can clearly see the entire building, which consists of a 330-meter-long north-south art corridor and a 200-meter-long east-west axis connected by the west hall, central hall, and east hall. The design of “two axes” reflects the symmetrical beauty of traditional Chinese culture. "Area 1" refers to the intangible cultural heritage display area formed on the underground floor consisting of the National Expo Theater, the Academic Lecture Hall (also used as a digital cinema), and the studio.
