自從清初馮浩注〈燕臺詩〉，懷疑李商隱與玉陽山女道士有不可公開的戀情，四百多年來不受此說影響者甚少。然真相如何？是本文探討的主要目標。而馮浩又具體指出：以篇中多引仙女事，故知女冠。」因此乃從「用典」的角度切入，以探討以下幾個問題：一是李商隱與道教之接觸，有那些具體之事實與念？二是李隱與女道士之關係，到底有何糾葛？在時間與地點上有無具體證據？三是馮浩說〈燕臺〉詩多女仙典，故知為女冠作，其文本真相如何？四是〈燕臺〉可能之託或象徵是什麼？

Over the past four hundred years since Feng Hao expressed his suspect that Lee Shangyi had unspeakable love affairs with Taosist priestesses in Mount Yuyang in his commentary to Li’s poem, “The Poem of Yuntai,” in the early Ching dynasty, few have not been affected by his remarks. However, no one can be certain if Li actually had an affair or not. The primary purpose of this paper is to find out if these affairs are history or mere speculations. Meanwhile, Feng Hao specifically pointed out that plenty of allusions of :”fairy maidens” in this poem implied that it was written for Taoist priestess. Through an analysis of these allusions, I intend to answer the following questions in this paper. First, what was Li Shangyin’s attitude towards Daoism and how did he contact with his Daoist friends ? second, what was the actual relationship between Li Shanyin and some Tasoist priestesses? Was there any concrete evidence such as the possible time and places in which they met? Third, Feng Hao held that plenty of references to “fairy maidens” in the “Yentai” poem indicate that it was written for Taoist priestesses. Is that really what the text was about? Fourth, what does “Yentai” allegorize or symbolize?
