Objects from the south often had “exotic property” 殊方异物 in the object-chanting fu咏物赋 of ancient era. Scholars’ research in the past focused on Wei， Jin， Southern and Northern Dynasties， with less emphasis on Tang Dynasty. In Tang scholars’ object-chanting fu， the objects from the South， while inheriting the nature of “exotic property” from the tribute-writing tradition of the Six Dynasties， gave rise to an analogical relationship between gongwu 贡物 and gongsheng 贡生 in the context of imperial examination. With the increase of literati’s firsthand knowledge and experience about the South from their venture to the southern regions， the scope and attributes of things in the south changed from the exotic to the ordinary， diversifying literati’s metaphorization of similar objects， changing the writing of object-chanting fu by Tang writers and updating the metaphorical system of southern sensory literature since the Shi sao诗骚 tradition. The diversity of object-chanting fu about southern things in the Tang Dynasty presented a fu landscape interweaving “orthodox voice” 正声 and “changing voice” 变声 under the backdrop of centralized political culture， serving as a restoration to the “praise and satire” tradition established by Chusao楚骚 and Hanfu汉赋， rather than a “halfway decline” 中衰.
