Appreciation of Song of Eternal Sorrow;

Song of Eternal Sorrow is a famous masterpiece in Bai Juyi's poems. Written in the first year of Yuanhe (806), the poet served as county magistrate in yi county (now Zhouzhi, Shaanxi). He visited Xianyou Temple with his friends Chen Hong and Wang Zhifu, and wrote this poem because of the story of Emperor Xuanzong of the Tang Dynasty and Yang Guifei. In this narrative poem, the author narrates the love tragedy of Tang Xuanzong and Yang Guifei in the Anshi Rebellion with refined language, beautiful images, narration and lyricism: their love was destroyed by their own rebellion, and they were endlessly eating the bitter fruit of this spirit.

Tang Xuanzong and Yang Guifei are both historical figures. Poets do not stick to history, but rely on a little shadow of history. According to the legend of the people at that time, the singing of the neighborhood has degenerated into a tortuous and touching story, which is described and sung in a reciprocating and touching art form. Because the stories and characters in the poem are artistic, and they are the complex and true reappearance of people in reality, they can ripple in the hearts of readers in past dynasties.

The song of everlasting regret is the song of everlasting regret, which is the theme of the poem, the focus of the story and a touching seed buried in the poem. As for what you hate, why do you hate it for a long time? The poet does not tell and express directly, but shows it to readers layer by layer through his poetic stories, so that people can guess, remember and feel for themselves.

The first sentence at the beginning of the poem: "The emperor of China longed for the beauty that might shake an empire" seems very common, as if the story should be written from here without the author's attention. In fact, these seven words are extremely rich, which is the whole program, which not only reveals the tragic factors of the story, but also evokes and directs the whole poem.

Then, in extremely frugal language, the poet described how Xuanzong of the Tang Dynasty emphasized color and sought color before the Anshi Rebellion, and finally got Yang Guifei, who said, "As long as she turns her head and smiles, there will be a hundred spells, and the makeup of the sixth palace will go up in smoke." It describes the beauty and charm of Yang Guifei. After entering the palace, he was favored by color. She not only "inherited her kindness", but also "listed all her sisters and brothers in the soil". Repeatedly rendering how Tang Xuanzong indulged in debauchery, how to have fun, and how to indulge in singing, dancing and drinking in the palace all day. All this led to the Anshi Rebellion: "Until the drums of war exploded from Yuyang, shaking the earth and breaking the tune of rainbow skirts and feather clothes". This part describes the internal cause of "long hatred", which is the basis of the tragic story. Through the realistic description of this court life, the poet ironically introduced the hero and heroine of the story: an emperor who valued the country and despised the people, and a charming and pampered concubine. This also vividly implies that the misunderstanding of Tang Xuanzong is the root of this tragedy.
