Therefore, from the content, the first paragraph of the poem, "I left gently, just as I came gently, I waved goodbye to the clouds in the western world", can be summarized in several words: slow rhythm, light movements, lingering affection, and a touch of sadness. Also, I would like to add that as a farewell to the clouds in the western sky, the rosy clouds in the western sky give us the impression that they have laid a gorgeous color for the later description, and the whole scenery is reflected by the sunset. So use this sentence to sum up and set the tone for this poem.
In the last paragraph, "I left quietly, just as I came quietly and waved my sleeves without taking away a cloud"-"Cloud" is symbolic and represents a rainbow-like dream. It was reflected in the water, but it was not taken away. Therefore, to bid farewell to Cambridge is not to bid farewell to his alma mater, but to bid farewell to Cambridge culture, which has brought the greatest change to his life. It bid farewell to the Cambridge ideal and played a role in deepening the theme.
Structurally, the front and back paragraphs have played an echoing role; Moreover, the first sentence and the last sentence are repetitive, which strengthens the sense of rhythm, and the words inside are overlapping. For example, Quiet and Gently embodies the musical beauty of Xu Zhimo's poems (the "three beauties" of the old and new poetry schools, namely, the beauty of painting, architecture and music). The beauty of music is what Xu Zhimo emphasizes most)
