《长生殿》中李杨爱情历来为人称道，然而也有观点认为帝妃之间没有真正的爱情。笔者意图从女性视角分析李杨爱情中存在的进步性与局限性，总结《长生殿》中洪昇的爱情观。首先，通过评述传统研究对李杨爱情“嫉妒论”、“完美论”和“知音论”等观点，笔者阐明了对传统研究中不合理褒扬的否定态度；其次，通过结合文本细致具体地分析李杨爱情的产生与发展，指出李杨条件的不平衡性、爱情进程的不合理性，进一步阐发笔者关于传统研究“女祸论”等观点的认识，得出李杨爱情虚幻性的结论；最后，总结回扣正文内容，得出核心观点：洪昇爱情观与社会观紧密结合，李杨爱情作为“戒鉴”反衬出的是传统社会统治者的理想爱情；《长生殿》的内在矛盾性反映出洪昇思想进步与局限的深层交织；用结论反推文章细节，展望洪昇触及边缘的“真正理想爱情”。

The love between Li Longji and Yang Yuhuan in The Palace of Eternal Youth has always been praised, however, there are also views that there is no real love between the emperor and the princess. The author intends to analyze the feudal nature of their love from a female perspective, and summarize Hong Sheng's view of love in The Palace of Eternal Youth. Firstly, by reviewing the traditional studies on the "jealousy theory", "perfection theory" and "soulmate theory" of the love, the author clarifies the negative attitude towards the unreasonable praise in the traditional studies. Second, by combining the text with a detailed and specific analysis of the generation and development of their love, the author points out the unbalanced conditions of the two and the unreasonableness of the love process, further expounding the author's understanding of the traditional study of "female woe theory" and other views, and concluding that the love between Li Longji and Yang Yuhuan is illusory; finally, summarizing the content of the text, the core view is reached. The conclusion of the essay reflects the deep intertwining of Hong Sheng's ideological progress and limitations; the conclusion is used to deduce the details of the essay and to look forward to Hong Sheng's "true ideal love" that touches the edge of the true ideal love.
