In terms of character description, Xing Xiuyan, Li Wen, and Xue Baoqin are all new characters and should be somewhat exaggerated. However, they had just arrived in the Jia Mansion, so they should not dominate the poems composed by the other sisters. Therefore, apart from Xue Baoqin's many poems, Lu Xu'an's couplets still only highlighted Shi Xiangyun. Everyone then asked them to write another red plum poem, which was the author's supplementary work. He took this opportunity to give some hints about their identity and characteristics, and he hinted at it through poems. The author once used Wang Xifeng's eyes to introduce that although Xing Xiuyan "comes from a poor family and has a hard life", "he is not like Mrs. In her poem, the red plum blossoms bloom against the cold and are difficult to distinguish from spring flowers. Although they are located in the ice and snow, their colors are unusual, which vaguely contains these meanings. Li Wen's sister is the daughter of Li Wan's widowed aunt. Judging from the words in the poem, such as tears stained with blood and heartbroken, she also experienced misfortune or expressed the pain of losing her father. "Message Bee Butterfly" should not be frivolous. It can be seen that he relies on his integrity and his character is quite similar to Li Wan. This is probably caused by the different environmental upbringing among the Li Shouzhong clan who pay attention to Confucian "moral education" . Xue Baoqin is a lady in the "Four Great Families", and the "luxury" aura of the daughter of a wealthy family is stronger than the others. In the novel, there is a paragraph dedicated to her "stunning beauty" in which she hugs red plums and reflects in the white snow. Her poems are like self-portraits. Jia Baoyu claimed that he "can't couplets" and was afraid of "dangerous rhymes", so he often failed to write poems with limited titles and rhymes. He implored everyone: "Let me use rhyme myself, don't limit it to rhyme." This is not because he is dull in thinking, but because his character does not like those artificial constraints in form. In order to prove this point, he was "punished" to write two more poems with no rhyme limit to sing about his own facts. Therefore, this time Shi Xiangyun's "drum" has not stopped, but Jia Baoyu's poem has been completed. Poems written casually are innovative. For example, the metaphor of "cutting purple clouds" is borrowed from Li He's poem without imitating its meaning, and the phrase "staining moss in the Buddhist courtyard" has not been seen in previous works. Poems reveal their temperament everywhere. "Joining the world" and "leaving the world" are reminiscent of Jia Baoyu's "origin" and destination. Not asking for "dew in a bottle", but only for "plum blossoms outside the threshold", Jia Baoyu later became a monk not to practice Buddhism, but to escape reality and "walk beyond the iron threshold". These, at least in terms of artistic effect, enhance the precise and rigorous plot structure of the book.
