The theme of"Chang'an Road"originates from the Six Dynasties period.Poets,inspired by memories and yearnings for the Han Dynasty's Chang'an,crafted a city roadscape that merges the real and the imaginary,infused with echoes of southern capital cities.This mode of depiction is characterized by formulaic patterns,ornate rhetoric,and a sense of virtualization.With the restoration of Chang'an as the capital during the Sui and Tang dynasties,the"Chang'an Road"theme experienced a resurgence,becoming a significant element of early and flourishing Tang literature.Tang poets imbued the theme with the vibrant and uplifting spirit of the era,portraying the road as a symbol of marvels and grandeur while integrating personal aspirations for fame and recognition into their writings.Furthermore,the"Chang'an Road"acquired entirely new connotations.It evolved from a physical urban thoroughfare into a metaphorical path rich with political symbolism.This metaphorical transformation links homeland and foreign land,departure and return,forming a complete temporal and spatial loop.In doing so,it enriches and deepens the thematic significance of the"Chang'an Road,"adding new dimensions to this enduring motif.
