"Rain Alley" is Dai Wangshu's early famous and representative work. After the poem was published, it had a great impact, and the poet was called the "Rain Alley Poet". The poem depicts a gloomy picture of the alleys in Jiangnan during the plum rain season, thus forming a lyrical artistic conception rich in symbolic color. Here, the poet metaphorizes the dark and gloomy social reality at that time as a long, narrow and lonely "rain lane" with no sunshine, no vitality and vitality. The lyrical protagonist "I" is a lonely wanderer in such a rainy alley. "I" still cherish the longing and pursuit of beautiful ideals and hopes in loneliness. The "lilac-like girl" in the poem is a symbol of this beautiful ideal. However, this beautiful ideal is elusive and difficult to achieve. This mentality is a true reflection of the confusion and confusion that some young intellectuals who pursued something after the failure of the Great Revolution could not find a way out under political pressure. In terms of art, this poem also clearly reflects the creative characteristics of Dai Wangshu's early poetry. It not only adopts the Symbolist approach of emphasizing hints and symbols, but also has the Metricalist pursuit of musical beauty. The "I", "Rain Alley" and "Girl" in the poem are not specific portrayals of life, but lyrical images full of symbolic meaning. The whole poem also echoes a smooth rhythm and melody. The sense of melody mainly comes from the rhyme of the poem. In addition to the rhyme in the 3rd and 6th lines of each stanza, many sound groups that echo the rhymes are selected in the lines of each stanza. The use of overlapping techniques in the poem also enhances the musical effect. As Ye Shengtao said, "Rain Alley" "opens a new era for the syllables of new poetry."
