Song of Eternal Sorrow got its name because Emperor Xuanzong of the Tang Dynasty attached great importance to the country. He created an Anshi rebellion, brought irreparable suffering to the people and won their resentment. The love tragedy caused by infatuation and singleness in love has been closely related to heroes and beautiful women since ancient times, let alone a realistic authority. Therefore, when the author wrote this poem, his thoughts were two-sided, including criticism and allegory of reality and sympathy for the love tragedy of Don Juan.
The first half of "Song of Eternal Sorrow" satirizes the profligacy of Emperor Tang Ming and the chaos of the country and the people with realism. The first sentence at the beginning explains this view and paves the way for the following. By the side of the monarch "Yang Guifei", the "Emperor, from now on, abandoned his early orders" paved the way for the Anshi rebellion, which shows the inevitability of Anshi rebellion.
