The Song of Eternal Sorrow first gives us the enjoyment of artistic beauty, a moving story in the poem and a delicate and unique artistic conception. The center of the whole article is "Song of Eternal Sorrow", but the poet tries his best to write and render it with "thick ink and heavy color" as the starting point. "Work at sunrise and rest at sunset", "Don't go early", "Stay up late", "I can't get enough of it" and so on. , appear extremely happy, like a comedy. However, that kind of extreme joy is only in contrast to the endless hatred behind it. The dissoluteness of Emperor Xuanzong of Tang Dynasty led to a political tragedy, which in turn led to a love tragedy between him and Yang Guifei. The maker of the tragedy finally becomes the hero of the tragedy, which is a particularly tortuous part of the story and the reason why the hero and heroine in the poem have to "hate" for a long time. Many people say that the Song of Eternal Sorrow has a moral, and I think this is the moral of this poem. So, how does the poet express "long hatred"? After the death of Yang Guifei in Majipo, the poet described it very delicately, showing the inner contradictions and painful feelings of Tang Xuanzong who could not bear to give up love and wanted to save it. Because of this "blood and tears" death, there will be endless hatred. Later, the poet used a lot of pen and ink to repeatedly render Tang Xuanzong's yearning for Yang Guifei from all aspects, but the story of the poem did not stay at an emotional point, but with the gradual progress of the inner world of the characters, he perceived the constant changes of their scenery, pushed forward the time and story, and used the thoughts and feelings of the characters to develop and promote the development of the plot. After his death, Emperor Xuanzong of Tang Dynasty went to Shu and felt very sad. Still on the road, revisiting the old place has evoked sad memories; After returning to the palace, I experienced physical injury during the day and insomnia at night. I miss it day and night, so I hope to have a dream, but it is "the distance between life and death year after year, but no beloved soul has visited his dream". At this point in the poem, the "hate" of "long hate" has been written very touching, and it seems that the ending of the story is OK. But the poet's pen is curved. With the help of the colorful wings of imagination, he conceived a charming fairyland, which pushed the plot of the tragic story to a climax and made the story more tortuous, ups and downs. This turning point is both unexpected and reasonable. Due to the constant contradiction and collision between subjective desire and objective reality, poetry vividly shows the psychology of the characters, and the story is more moving.
