On the basis of the melancholy feelings in Dai Wangshu's poems, there are both classical life feelings in his poems. First of all, Dai Wangshu's love poems are obviously influenced by the poets in the late Tang Dynasty in expressing the privacy of love, and they use more female images in expressing love. In a sense, they can even be said to be a modern interpretation of the theme of acacia in Wen and Li's poems. At the same time, love has become one of the main contents of the poet's life experience, which embodies the modernity of Dai Wangshu's poems. In a word, Dai Wangshu's love experience is modern, and his love characteristics are modern, but the expression he endowed is classical and traditional. Secondly, the theme of mourning for autumn in Dai Wangshu's poems is deeply influenced by China's classical literature. Poets use the traditional theme of chanting autumn to present the sad feelings of loneliness and youth troubles of modern people, which strengthens the aesthetic tension of poetry. Understanding the consciousness of death hidden behind the theme of sad autumn can better understand the melancholy emotion in poetry. By analyzing Dai Wangshu's poems such as To the Firefly, we can also find that the poet's death imagination and writing style belong to the typical Taoist cultural system. Finally, the idyllic homesickness and pastoral feelings in Dai Wangshu's poems are a traditional expression of human feelings and have the charm of oriental poetry. The images of wandering and tired travelers are not only influenced by the images of travelers in China's ancient poems, but also the images of dreamers and Nightcrawler are obviously influenced by western symbolism, which constitutes a modern creative motif. As a poet deeply influenced by Chinese and western literature and culture, Dai Wangshu actively seeks the fusion point of Chinese and western poetry art and creates modern poems belonging to his own nation. Dai Wangshu's experience and practice in the national construction of new poetry inspire modern and contemporary writers: under the background of globalization, the creation of modern new poetry in China should be based on the aesthetic psychological mechanism of national culture, take the national spirit as the soul, absorb the artistic nutrition of foreign literature, and construct the nationality of China literature with the characteristics of the times.
