We will examine in this study the tradition of literati\'s writing xiaoshuo with the Commentary on the Travels of Mu, Son of Heaven(hereafere MZ) as the case study. The Literati in ancient China inherited the tradition of historian\'s \"assisting governing.\" We will trace the tradition of literati\'s writing xiaoshuo that literati\'s far-off journey was stemmed from their awareness of identity and xiaoshuo which translated the notion of far-off journey into literary manifestation was conceived by them as a supplementary history to supplement the present one. We will also try to explain that the far-off journey manifested in such texts as MZ is a kind of spatial history to create new identity and social order and that the text becomes a spatialized narrative by combining temporal sequence to the spatial history. We may see the MZ in Chinese literary tradition as the first fictional narrative that translates the idea of spatial practice into literary manifestation.
