Three beauties are rhythm beauty, painting beauty and architecture beauty. "Beauty of rhythm" emphasizes "level and rhyme" and "Beauty of painting" emphasizes that the choice of words should be gorgeous, bright and colorful; Every poem can form an independent picture. "Architectural beauty" emphasizes "symmetry of nodes and unity of sentences". Its main purpose is to have beauty in the content and form of poetry. Xu Zhimo's Farewell to Cambridge well practices this idea of "three beauties". First of all, in phonology, syllables are harmonious and have strong sense of rhythm. For example, in the first verse of the poem, the adjective "light" is used three times, which appears to be light in rhythm, soft in melody and slightly bouncing, as if the poet walks on tiptoe, which is in line with the joy of the poet's parting from Cambridge and with melancholy sadness; In terms of phonology, in two to six sentences, the standard of rhyming two or four sentences is strictly observed, and it is catchy and cadence, which is not only the poet's dream' foot sound', but also in line with the poet's emotional ups and downs. Secondly, in the picture, the words sunset, golden willow, sparkling, bride, green grass, aquatic plants, pool water, clear spring, rainbow, magnificence and so on constitute one picture after another. They are constantly flashing in front of readers, giving people visual beauty and endless imagination in color. In addition, these pictures not only give people a sense of beauty, but also make it easy for readers to feel the poet's reluctant feelings and understand the poet's lover-like feelings towards Cambridge. Readers get spiritual beauty all the way through reading. They unconsciously blend into the picture, blend in with the poet, and have an emotional sound with the poet. Finally, the architectural beauty, the whole poem has seven sections and four lines, and each section has similar words, which are randomly arranged and echoed in a circle, giving people a sense of beauty. The beginning and end of the two paragraphs echo with "gentleness" and "quietness" respectively, which makes the whole poem rigorous in structure and gives people the beauty of the whole. In terms of content, the first and second sections form emotional concern: coming smartly and walking lightly, which is the embodiment of the poet's permanent attachment to the past time when he revisited Cambridge after many years.
Farewell to Cambridge is to take the "three beauties" as the breakthrough point, and present the theme of bidding farewell to Cambridge, loving beauty and nature and reflecting the depressed soul to readers with picturesque images.
