What picture is depicted by parallelism in the third paragraph of the poem Dayan River? How do you express the poet's feelings? What's the use of repetition?

The narrative elements of this poem are integrated with the detailed description, and the appeal of the poem comes from the real and concrete detailed description of life. For example, in the fourth quarter, the eight parallelism sentences "After you ..." are actually eight details of life. On the one hand, they describe the extreme poverty and heavy housework of Dayan River, on the other hand, they show Dayan River's eternal care for infants, always giving him warmth and caressing him everywhere, which fully shows Dayan River's kindness, diligence and selfless love for infants. Another example is the eighth sentence of the poem, which truly shows her feelings for the baby through several typical details: during the Chinese New Year, she was busy cutting candy for the baby, and put Guan Yunchang painted by the baby in a prominent position. She couldn't help praising her baby to everyone, even dreaming, hoping that the baby would be happy, although it was impossible to tell anyone about this beautiful dream. These touching details show that Dayan and his love for his baby, like his own son, fully show Dayan and his beautiful and rich inner world. This is a great and selfless nanny mother, and the poet can't help singing a hymn of love. Therefore, without detailed description, there is no such appeal, and the poet's feelings cannot be expressed.
