Abstract: Micro-geographical space is a geographic space constructed from smaller-scale place names such as streets and lanes.This paper focuses on a unique narrative technique in ancient novels—micro-geospatial narrative, and interprets its relevant examples in Tang legends, then summarizes the basic function of this technique, and analyzes its use in the history of novels.The research found that the basic function of micro-geographical space in Tang legends is to enhance the sense of authenticity of the novel with its true geographical orientation, and some works use the micro-geographic space chain undertakes the dual functions of promoting the development of the plot and enhancing the rationality of the narrative.The narrative of the micro-geographical space chain of Tang legend may be closely related to three factors.The oral need before the text is written, the author's own Chang'an space experience, and "Chang'an imagination".Since the author and the reader no longer have the spatial tacit understanding of the same city, the micro-geographical space in the legendary novels of the Song and Yuan Dynasties is in a state of decline.On the contrary, because the two links of "speaking and listening" are of the same city, the vernacular huaben stories of Song and Yuan continue to use micro-geographical space narrative.

Key words: Micro-geographical space, spatial narrative, Tang legends
