杨国庆

Yang Guoqing, about whom limited public information is available, focuses his writing on China's ancient city walls and the urban construction of Nanjing in the Ming dynasty. Nine of his works are included here, among them the six-volume series on Chinese ancient city walls and a study of Zhu Yuanzhang and the building of Nanjing. His writing sits at the intersection of architecture and history, combining the forms of city walls and urban layout with specific historical figures and dynastic contexts, attending both to engineering details and to the political and cultural intentions behind construction. His works are often classified under history and architecture and suit readers interested in ancient fortifications, urban history, and the early Ming period, offering reference value in popularizing knowledge of city walls and advancing related discussion.
