Abstract: During Mid-Tang, as the systems for selecting officials gradually matured, bureaucrats who rose through the imperial examinations congregated in the capital.Chang'an served as the stage for their daily lives.There had been an interactive impact between the city and its residents.Firstly, Chang'an's development pattern affected residents within it.During Sui and Early Tang Dynasties, with Zhuque Avenue as the central axis, the Chang'an City was symmetrical from east to west, while the political status of the different blocks was equal.In the Middle Tang Dynasty, with the political center moving from the Taiji Palace to the Daming Palace, the importance of the eastern blocks had grown increasingly prominent.This had an impact on the lives of literati bureaucrats in Chang'an City.They gathered towards the central and southern parts of the eastern blocks, as well as the western blocks, their related activities in turn reshaped the sociocultural function of various blocks of Chang'an City.As representative figure in the 9th century, Zhang Ji's visit to Bai juyi across the Zhuque Avenue, and his achievement of living in the East through three relocations, should all be observed under this context.

Key words: the Middle Tang Dynasty, literati bureaucrats, urban functional zoning, Zhang Ji, Bai Juyi
