The emotions expressed in "Rain Lane" are multiple:
1. The projection of the darkness of reality and the disillusionment of ideals in the poet's heart
Here, The poet metaphorized the dark and dull social reality at that time as a long, narrow and lonely "rain lane". There is no sound, no joy, no sunshine. The poet himself is such a lonely person wandering in the rain alley. In his loneliness, he cherishes a beautiful hope, a panicked person and an unattainable ideal, which is a tragic theme that contains the characteristics of the times.
2. This is a lyrical artistic conception rich in symbolic color.
In "Rain Lane", the image of the girl has a tragic color, and the image of the lyrical protagonist, the wanderer (the image of the lonely wanderer runs through all Dai Wangshu's works) also has a tragic color. His pursuit is so noble and idealistic. He is looking forward to a girl who has both a deep inner world and charming charm; a girl who is both beautiful and unyielding in the face of hardships. However, he himself is so difficult to be understood by others. He neither knows himself very well nor understands the other party very deeply; perhaps what he expects is always the memory in his heart.
