The Palace of Immortality describes the traditional and popular love story between Tang and Yang Guifei. Since Bai Juyi's Song of Eternal Sorrow and Chen Hong's Biography of Song of Eternal Sorrow first wrote the true stories of Li and Yang into poems and novels, many literati in the Song, Yuan and Ming Dynasties repeatedly used this theme to create poems, novels and operas. Such as drama, Bai Pu's Wu Tongyu in the Yuan Dynasty and Wu Shimei's The Legend of Jing Hong in the Ming Dynasty. It can be seen that different times and different authors can extract works of art with historical significance and aesthetic value from this ore that condenses the love between the emperor and the princess. It is with this retrospective aesthetic vision that Hong Sheng discovered the love value of "the imperial family's love is rare", and at the same time believed that it contained the historical experience of "great sorrow, warning the afterlife". On the basis of predecessors, he chose and tailored with outstanding artistic talent, reappeared this vast historical scene, and finally made the dramatic works describing this historical theme reach a summative artistic height.
The palace of eternal life is fifty years long. The whole drama festival basically follows Bai Juyi's Song of Eternal Sorrow, but as a drama, it has more characters, more scenes and richer content. It takes the love story of Emperor Ming of Tang Dynasty and Yang Guifei as the main line, and the political events of An Shi Rebellion as the social background and mutual inspiration, and writes that the love of imperial concubine has brought political disaster and people's suffering. The first half is a realistic description, and the second half is a romantic novel. It is written that Tang and Yang Guifei fell in love deeply on earth, in heaven, and then reunited in the Moon Palace, showing a "human" structure. So the plot is tortuous, the scene is broad, the organization is tight, and the clues are clear. It is a large-scale drama with rich performance effects.
