"A Night in Feilengcui" is a modern poem by Xu Zhimo, a representative poet of the Chinese Crescent School. It was written during his European trip in 1925, in Florence, Italy (known as Feilengcui in ancient times). The poet uses delicate brushstrokes, romantic emotions and musical language to simulate a woman's complex and contradictory psychology on the eve of separation: there is deep attachment, gratitude and happiness to her lover, but also helplessness, pain and sorrow. The emotions are advancing layer by layer, full and touching. This poem is different from the condensation of many of Xu Zhimo's short poems. Instead, it presents a spiritual experience affected by love and separation through rich images and emotions, making readers feel as if they have personally experienced the emotional waves of that night. As one of the important chapters in Xu Zhimo's poetry creation, "A Night in the Emerald Green" demonstrates his mature style of romantic aesthetics and lyrical expression, and is widely praised for its unique artistic conception and profound emotions.
