Rain Lane is a famous work by Dai Wangshu, a famous modern poet in 1930s, and it is a lyric poem with symbolic meaning. There are three simple images in the poem: "I"-a lyric hero who symbolizes the pursuit of truth. Lilac girl ―― a symbol of truth. The long rain lane symbolizes the gloomy real world. The rain lane in the poem is long and lonely: raindrops hit the oil-paper umbrella, which adds to the loneliness of the rain lane. The wandering of the lyric hero "I" in the poem makes the rain lane longer. "I" is a wanderer who yearns for the past and hopes to meet a girl like lilac. But this girl is very sad. The fence of her house fell down. Although it was destiny takes a hand, she didn't degenerate or beg. She is still so charming, so cold and so arrogant. The poet insists on pursuing human dignity and life here. It is obviously meaningful for the poet to compare lilacs to girls. Lilac is a trinity symbol of beauty, purity and hostility. The "lilac-like girl" here has double meanings: one refers to reality; One is a symbol of unattainable pure knot ideal, and this girl is often his ideal. The girl appeared, but like a dream, she only flashed in front of her eyes and disappeared in an instant. It says here that lilacs are beautiful, but they fade easily. In this way, the poet expressed the belief that the pursuit of beautiful ideals was futile and lonely.

From the deeper symbolic meaning of poetry. Because symbolic literature focuses on containing a certain meaning, thus embodying suggestibility. In this poem. The image of a girl is actually the poet's ideal. His wandering search is to find the girl-now, the girl appears, but her footsteps, her color, together with her sigh and melancholy, all have unattainable symbolic significance-persistent pursuit can not be grasped. The girl like lilac that the poet expects is so noble, with idealized color, beautiful soul and charming appearance. But girls like that are hard to find. So, in the face of idealistic expectations. "I" is always confused, with a sense of temperament tragedy, which runs through the whole poem, through the rendering of long and lonely rain lanes, decaying fences, cold complaints and drizzle, the superposition of lilac-like girl images, and the vagrants' illusory expectations for girls. Everything is not clear, not clear, but we understand and feel it. This is a feature of symbolic literature-suggestibility. The function of this kind of literary image is to inspire people to appreciate and understand deeper meaning through the surface of the image.

Another feature of symbolic literature is obscurity. Poets use symbolic artistic techniques to express their pursuit of wealth and existence, as well as their melancholy and emptiness. I'm not sure what the poet's ideal is. It is just an emotion, an instant feeling and mood, which actually reflects the poet's loneliness, loss and melancholy in the dark real society. The feeling of this poem is unpredictable, the inner state is erratic and the image is vague. It is necessary to have the poet's sincere feelings as the backbone, and there is little overhead lyricism, which is extravagant and not empty. The poet puts his feelings first, and tries to hide this history as much as possible by means of suggestion, and tries to cover up the truth. The poet did not limit the meaning of the poem to one level, which made us understand more from the poem.
