What is the political implication of Li Bai's Farewell?

Farewell has its political meaning, but its theme is extremely obscure, and people have argued for thousands of years. At the end of Tianbao, Xuanzong of Tang Dynasty was abandoned politically. He served as Yang and An Lushan for external use. With the abdication of power, the internal contradictions of the ruling class continued to develop, and finally the Anshi Rebellion broke out. The poem repeatedly emphasizes the problems of "the monarch loses his official position" and "the power belongs to his official position", and says, "What is the heavy pupil in a lonely grave?" , all contain deep feelings. Obviously, it's not just about singing historical themes, but about connecting with reality. Otherwise, "what can I make up for it?" Nowhere to find. Chen Ling's poem is better than Xing Jian's, "So the song of everlasting regret is better than the farewell song." Angel's New Notes on Li Bai's Poems said: "Farewell is a sad song of the disillusionment of the poet's ideal, and it is also an elegy sung by the poet to the Tang Dynasty, which is about to be chaotic." The poem begins with the description of the pain of the separation of two concubines and ends with the mourning of two concubines, which makes the tragic story cover the whole article and maintains the artistic integrity. The whole poem adopts the expression of Chu songs and Sao styles, which constitutes a profound artistic conception and strong artistic charm!
