This book delves into the deep connection between the layout of the Forbidden City and the knowledge and philosophical systems that underpinned the formation and evolution of ancient Chinese civilization. Drawing on a wealth of examples, the author demonstrates that while the Forbidden City was constructed in the later periods of ancient China, its architectural principles could be traced back to ancient astronomy and humanities, extending all the way back to the very beginning of agrarian civilization. With its architectural layout and symbolic significance, the Forbidden City stands as a monument to the enduring Chinese civilization.
