The basic content of this poem is the same, except a few words. Do you find it repetitive? Why? Please briefly explain the reasons.

This poem has three overlapping chapters, and each chapter has four levels.

The first two sentences begin with the combination of the two, showing a picture of autumn scenery along the river: the river is Vivi, the reeds are green, and the dew is frost and snow. This scene, with a slightly sad tone in the cold loneliness, well exaggerates the atmosphere and sets off the persistent pursuit and elusive love mood expressed in the poem.

Three or four sentences are the central image of the poem: the lyric hero lingers by the river, longing for the "Iraqi people" on the other side of the river. This "Iraqi" is the one he misses day and night. "On the water side" was isolated, forming a difficult situation. The protagonist gets up early and says hello late, always looking forward to it. His persistent love spirit can be seen. But "Iraqi" is irresistible, illusory and elusive, so the poet's heart is full of helpless emotions and empty and melancholy feelings.

Five or six sentences are a concrete case of "being on the water side": the pursuit of going upstream, endless difficulties and obstacles, endless journey, out of reach. This is one of the common unpredictable situations, and the pursuer's melancholy mood is also enhanced.

Seven or eight sentences is another concrete scene of "being on the water side": going downstream, the journey is smooth everywhere, the Iraqi people are always there, but they seem to be true and unreal, and they are finally inaccessible. This is also one of the common situations where it is difficult to see the situation clearly, and the disappointment of the pursuers is therefore stronger.

Through the repeated descriptions of general description, sub-description, countercurrent and downstream, the whole poem clearly shows the vision and pursuit of the water side, and fully shows the lyric hero's persistent pursuit of love and the empty and melancholy mood that he can't pursue.

"City" consists of three chapters, each chapter is replaced by a few words, which not only plays the artistic effect of repeating chapters and sentences, chanting repeatedly and singing three sighs, but also plays the role of promoting poetry layer by layer. From "White dew is frost" to "White dew is?" , and then to the "Millennium", is the continuous passage of time, which means that the protagonist hopes to pursue the length of time and shows the protagonist's persistence. From "on the water side" to "on the water side" to "on the water side?" From "ten thousand in the middle of the water" to "ten thousand in the water" to "ten thousand in the water?" This is the change of location, which means that "Iraqi" is illusory, mysterious and hard to find. The harder it is to pursue, the more it can show the sincerity of the seeker. From Road Obstacle and Long to Road Obstacle and Broken to Road Obstacle and Right, the pursuit process is difficult to render repeatedly. The more difficult it is, the more sincere and persistent the protagonist is.

Repeating chapters and sentences and singing three sighs are common forms of ancient folk songs and modern folk songs. Its aesthetic value should be viewed from two aspects: first, from the emotional aspect. The emphasis is on emotional people. Emotion is not a litchi that acts on people, and it can not be effective by one-time concept notification. It takes repeated infection to have a touching effect. Second, from the perspective of music. Ancient folk songs are all sung orally, using tones and melodies to infect people's emotions. Singers have to repeat it to enjoy themselves, and listeners have to repeat it to gain emotion. Therefore, singing three sighs and going back and forth itself is to promote feelings at different levels, that is, to continuously strengthen aesthetic effects. There is no need to regard the development and change of each chapter as progress. This should be realized.
