"Farewell to Cambridge Again" is about the poet Xu Zhimo who returned to England in 1928 on his way back to his country. He revisited his old place and the scenery of Cambridge reminded the author again. But parting is imminent, which arouses the poet's intricate thoughts and writes a beautiful article. The prose mainly describes the natural beauty of Cambridge and expresses the author's reluctance to leave Cambridge and his inner melancholy. It is one of Xu Zhimo's most influential works. The specific analysis is as follows: Kangqiao gave Xu Zhimo the most profound memory. So when I want to say goodbye, the past will fill my heart like the aroma of old wine. Xu is like this, and the scenes of Cambridge in the past reappear before his eyes: golden willows, green water plants, and pools of water. These three images express the author's attachment to Cambridge. The intensification and sublimation of this attachment should be said to have begun in the fifth section, "Looking for Dreams──", and it was the "rainbow-like dreams precipitated in the water" that reminded him of his old dreams, those lingering "dreams" Memories of "long-cherished wishes" and "ideals". The scenery remains the same, the personnel are completely changed, and it is destined to be impossible for the poet to find old love again. So "I couldn't sing" and "had to be silent." The one who is "silent" at this moment is not "Cambridge Tonight" but the author himself. The poet has completely fallen into the sweet memories of his past life. When the author wakes up, he realizes again that he is saying goodbye, which brings a bit of bitterness, loss and unspeakable feelings to the end of the poem. Therefore, this last "wave of sleeves" came with a bit of helplessness. The poet did not want to take away a cloud. The cloud was probably those dreams. The poet may just want to treasure it in his heart forever.
