李商隱詩一向以多義、難解著稱，尤其是他「自創詩體」的無題詩作，自明清以來，作箋者眾，而附會紛紜亦多；然則，歧義、多解、非線緎跳躍遊走的語言，所導致的詮釋不一的現象，正近代西方閱讀理論的思考中心，──本文以李商隱無題詩〈鳳尾香羅〉一首為例，取明清以來，暨近代坊間流行之注釋、翻譯本，參照以相關唐李詩例，以及唐代社會習俗等記載，重新提出對此詩之文本詮釋，並以此探討閱讀與詮釋之間的關係，以見其多向性文本之閱讀趣味。

　　　　　Li Shang-Yin's poems, especially his “self-creative style” poems, have long been designated by his multi-scope reading comprehension (Dou-Yi) and hard reading. Since Min and Chin dynasties, many authors have tried to explore the meaning of Li Shang-Yin's poems from different viewpoints and resulted in non-consistent and various interpretations of the same issue. Nevertheless, non-consistent and various interpretations are the central thinking of modern Western Reading theory. In this paper, an attempt was made to re-explore the interpretation of Li Shang-Yin's “Fong Wei Shang Lou” based on the recent findings from the Interpretation and Translation Books published in Min and Chin Dynasties, poems in Tang and song Dynasties as well as custom in Tang Dynasty. In addition, the correlation between reading and interpretation is established to figure out the wonder of multi-scope reading comprehension behind the Li's poems.
