"Pipa Xing" as a long narrative poem, recounting the poet in the river to see off the guests, the parting encounter with the lute woman, attracted by the sound of the lute woman's music and listen to the lute woman to tell the story of the desolate life, and thus associated with their own bumpy, tortuous career encounters, triggering the poet on the unrecognized talent and the encounter of the injustice of the sadness of the feelings, so as to express dissatisfaction and resentment towards fate, exposing the ancient feudal society, political environment and darkness [1]. The poet's encounter with talent and injustice triggered the poet's sadness about his fate, thus expressing his dissatisfaction and resentment, and exposing the darkness of the political environment of the ancient feudal society. This poem is beautifully worded, rhetorical, emotional, far-reaching, not only by the intellectuals of all dynasties, but also widely circulated in the city folk, reaching the height of universal appreciation, the value of its work beyond its own literary value. The Pipa Xing is different from other narrative poems in ancient China, breaking the barrier of traditional narrative poems and adopting the narrative means of "intercepting cross-section", which opens a new chapter in the writing of narrative poems in ancient China. Ancient Chinese narrative poetry is mainly based on plain narrative, advocating the narrative method from beginning to end. For example, the narrative poems in ancient China, especially the Lefu narrative poems of the Han, Wei and Six Dynasties, are always narrated in a plain way from the beginning to the end. For example, the "Orphan's Row" and "Southeast Flight of the Peacock" in the Han Lefu poems, all of them are in the way of flat narrative, the cause of the event, the development, the climax and the end of the development along the order of a smooth to the end. Pipa Xing, on the other hand, adopts a completely different narrative style from the previous ones, using unique narrative techniques such as flashbacks and interpolations to depict the sad life of Pipa girl and her own bumpy and twisted political fate, and interspersing these two sets of key events into the beginning, middle, and end of the poem, combining the encounters and emotions of the Pipa girl and the author with the phrases "Seeing off a Guest at the River" and "Stagnating in the River", "Seeing off a Guest at the River", and "Sending off a Guest in the River". The combination of the encounter and emotion of the pipa girl and the author with the scenes of "sending off the guest on the river", "staying to listen to the music" and "inviting to play" makes the development of the events of the poem and the text tightly-paced, perfectly accentuates the climax of the development, and expresses the author's depressed and heartbreaking emotion in the best possible way [2 ]. This kind of straightforward narrative means and the perfect combination of the lyrical way of feeling in the matter, deepen the emotional concentration of the poem, enhance the effect of the author's emotional expression. In Pipa Xing, Bai Juyi perfectly expresses his inner emotions through rhythm and rhyme with the help of music, and from another point of view, the author carries out the hidden lyrical behavior through the description of the pipa music in the poem. In another way, the author is hiding the lyrical behavior through the description of the pipa music in the poem. The icy spring is cold and the strings are frozen, and the sound of the pipa is suspended." In this line, for example, "the warbler's voice" initially reflects the sound, and "slippery flowers" further describes the pipa's mellow and smooth sound, and its melodious and melodious sound, which is a description of the physical aspect of the pipa's sound; whereas "difficult to flow under the ice" reflects the obstruction of the pipa's sound, and "difficult to flow under the ice" is a description of the pipa's sound. The next phrase "under the ice" embodies the meaning of obstruction, occlusion, etc., which is a metaphor for the bumpy and uneven career path; this line of the poem is the author's depiction of the pipa sound, which contains his feelings about the unfairness of destiny and the official luck of the career path. And then "the silver bottle first breaks the water pulp burst, the iron horsemen protruding swords and spears sound. At the end of the song, the pipa is drawn to the center of the heart, and the four strings sound like cracking silk." For example, the poem describes the sound of the pipa as "the silver bottle is broken at first" and "the iron horsemen stand out", in which the words "at first" and "stand out" emphasize the importance of the pipa's music. "emphasizes the pipa sound of the twists and turns and changes, so that readers feel that the pipa sound in the poem is like a surprise attack, implicitly reflecting the author's heart for a variety of encounters is not as light as the surface, but has been a turbulent, the author's state of mind at this time as a star has been a prairie fire, for the next outbreak of emotion, the fate of the injustice of each other laid the groundwork for the [3]; the second half of the line In the second half of the line, the words "the end of the song" and "like cracking silk" describe to the readers the sound of the pipa's conclusion as if it were an extremely harsh sound, which can be seen that the pipa woman's emotions have reached the edge of the outbreak in the poem, and at the same time, the author's emotions have been triggered to the apex. This series of depictions of the pipa sound and allusions full of personal emotions immerses the reader in the undulating, tumultuous musical realm, facing the author's surging _heart_ emotions at that time. Third, the melting of emotions in the scene "all scene language are emotion language", the author seized the characteristics of the scene, in the poem detailed depiction of the construction, through which the pipa woman and their own emotions, and with the scene change to move different inner feelings, fully reflecting the author melting emotions in the scene, the melting of emotions in the scene means of lyricism. For example, in the opening part of the poem, the author first depicts "sending off guests at night at the head of the Xunyang River, maple leaves and dirigible flowers in autumn", presenting readers with a picture of a bleak, autumn-colored send-off scene, thus accentuating the author's heart's unwillingness to part with and sadness, and rendering a depressing and low atmosphere [4]. It can be seen that in Pipa Xing, although the author's descriptions of the scenery are few, they contain the thoughts and feelings of the characters everywhere. Source: Young Literati
