Since the Han Dynasty, cities have been a very important theme of fu poems, where the majesty of cities and the magnificence of the fu genre add additional splendor to each other. This is exemplified by the statement in the ”Fu on Explaining the fu Genre,” The Literary Mind and the Carving of Dragons: ”Capitals, palaces, royal hunting gardens, and hunting journeys not only function as records of one's deeds and ambitions but also help to rule the country, so it is very important that they carry great meanings.” Urban space discourses in recent years further argue that cities are not only a geographical concept; their locations and landscapes are in fact closely connected with symbols, emblems, and power. Therefore, I explore the writing strategies of fu poems in the Southern Dynasties that take cities as their themes, and discover the following two pieces of information. First, despite the importance of richness and grandness in Han fu writing, a few special urban fu poems of the Southern Dynasties put emphasis on the rising and falling of cities. Second, after the suffering of Jiankang's destruction, all urban writers are influenced to write about it in different aspects. In conclusion, urban writings in this period often include destruction narratives, whether their writers have experienced the destruction in person or not. This kind of destruction narratives become Southern Dynasties writers' comments on their era and a significant image for later generations to write about the Southern Dynasties.
