Reviving 13th-century pop-up book art form, this book transforms the very act of page-turning into an urban memory of Beijing’s central axis, with the Chinese character “中” (meaning “center”) becomes an architectural blueprint. With the ancient perspective of time and space and Kaogongji (The Artificers’ Record) included in the Rites of Zhou as a guide, the book explores the four unique dimensions of Chinese cultural inheritance—xiang (symbol), xing (form), yin (sound), and yi (meaning). It traces the origins of the architectural regulations for the Yuan Dynasty’s capital planning and the subsequent formation of the buildings along Beijing’s central axis, showcasing the traditional cultural thoughts of the unity of heaven and humanity and the philosophy of governance from the center.
