The poem not only describes the tragic life of Dayan River, but also expresses the poet's rich thoughts and feelings through the narration of the unfortunate life experience of Dayan River. On the one hand, the poet expressed his love for Dayan River while shaping the image of Dayan River. In his poems, the poet repeatedly emphasized the nurturing relationship between Dayan River and "I", saying that he was "the son of Dayan River who grew up eating Dayan River's milk" and Dayan River "deeply loved her breasts". Because of this, the poet is very grateful for the cultivation of Dayan River, and he also admires and loves Dayan River. On the other hand, while praising Dayan River for selflessly raising her young children, the poet also expressed his indignation at the dark society that brought endless misfortune to Dayan River by telling about its unfortunate experience. With anger in his works, the poet said that his poems were written for "the curse of the unjust world". At the end of the poem, after expressing his deep love for Dayan River and great resentment towards the dark society, the poet announced with deep affection that he would "dedicate his poem to all the nannies and their sons on the earth,/to Dayan River who loves me as his own son". Here, the poet sublimated his love for Dayan River, his foster mother, into love for all the working people who share the same misfortune with Dayan River, sublimated the thoughts and feelings of his works and deepened the theme.
This is a long poem with a good combination of lyricism and narrative. The most prominent artistic feature of long poems is the successful use of parallelism, contrast and other techniques to express feelings, and the unique artistic effect of profound feelings is received. For example, in the fourth season, eight parallel sentences of "In You ……" were used to spread the story, which received a unique artistic effect of highlighting the hard work and hard life of the characters. Another example is "She is smiling ..." in the seventh section, which is like a set of close-ups, vividly reflecting the scene of great research and hard struggle, and showing her generous and kind mind and humiliating character. For another example, in the last section, the poet expressed his deep nostalgia for Dayan River and his love for the working people who are as kind as Dayan River with seven parallel sentences. Here, the poet expresses his inner feelings in the form of compound sentence, which truly conveys the poet's warm and sincere emotional waves, enhances the lyrical atmosphere of his works, and has shocking power. In addition, in order to portray the characters well and convey the poet's rich feelings, long poems also use contrast techniques in many places. For example, the life of Dayanhe in the fourth quarter is in sharp contrast with the life of my biological father and mother in the sixth quarter. The poet loves the poor Dayan River deeply. For the rich biological father and mother, the poet repeatedly stressed: "I am a new guest in my parents' home" and "I am uneasy". Here, the poet's love for the former and his strangeness to the latter form a strong emotional contrast. The use of this contrast technique highlights the poet's love for the working people and his hatred for the exploiting classes, which plays a role in deepening the theme.
Another outstanding feature of this poem in art is its simplicity. The poet is very good at describing scenes and writing feelings with daily spoken language and simple descriptions, which makes his works full of life and has a unique simple beauty. For example, in Dayan River, I wrote "During the Chinese New Year" and "Busy cutting the sugar of that winter rice". For the baby, I pasted the baby's "Guan Yunchang painted with bright red and green" on the wall next to the kitchen stove. These pen and ink captured the seemingly ordinary people and objects in daily life, which not only filled the works with life breath, but also showed Dayan River's meticulous love for the baby. Furthermore, the work describes the funeral of Dayan River, grasping the ordinary and distinctive images in life such as coffins, straws, paper money and ashes, and sketching out the sloppy and desolate funeral of Dayan River with a few strokes. These seemingly unpretentious pen and ink truly convey the tragic fate of the characters and the poet's deep grief over Dayan River.
