南京城市建设始终是中国城市建设的一个风向标。从历史学的角度看,在六朝时期的梁朝,南京已经被建成了当时世界第一大城市。后来唐朝时期的都城西安就是模仿了南京的皇城规划;到了明朝永乐年间,南京又被建造成当时世界第一大都市。后来永乐皇帝朱棣从南京跑到北京当皇帝,带走了南京皇宫的建筑师和工匠,建了一个南京式的北京城和皇宫。南 Nanjing’s urban construction has always been a benchmark for urban construction in China. From a historical point of view, in the Liangchao Dynasty during the Six Dynasties, Nanjing was built as the largest city in the world at that time. Later, the capital city of Xi’an in the Tang Dynasty imitated the imperial city plan of Nanjing; by the time of the Yongle Dynasty in the Ming Dynasty, Nanjing was built as the world’s largest metropolis at the time. Later Yongle Emperor Zhu Di ran from Nanjing to Beijing as an emperor, took away the architects and artisans of the Nanjing Imperial Palace and built a Nanjing-style Beijing city and royal palace. south
