【正文】 that “And the cuckoo, weary of empty hills, Singing to the xviii moon”(又聞子規(guī)啼月夜，愁空山 )（ Li Bai: “Difficult Roads in Shu”） (Gu Zhengyang, 2021: 167)expresses the difficulty on the road to Shu, etc. In modern times, poets like using “cuckoo” as an image. For example, Yu Guangzhong’s poem, “Seeking for Li Bai”, is the case. In reality, what he seeks is a kind of mon emotion that our nation widely has. That is his deep affection for homeland. In this poem, the poet uses “cuckoo” to show his homesickness. Therefore, in Chinese poetry, the cuckoo is only one element in poet’s whole conception. No matter which schools they stand for, poets are skillful in using this image. 4. Conclusion Poetry is one of the most excellent heritages in the world. And an image is the key concept in poetry, and is also the main way to express and exchange feelings for poets. The images of cuckoo and nightingale have appeared frequently in Chinese and English poems. By analysis and parison, we can realize that the usage of images of cuckoo in Chinese poems and nightingale in English poems is similar in general. Although their legends are different, they are the same to show grief and sadness. With the influence of their grievous legends, their calls are inspired with melancholy. They have been frequently used by poets. In spite of their similarities, when applied, the two images also have a few differences in the western world and China. The meaning that the nightingale symbolizes is double while that of the cuckoo is single: besides representing the meaning of desolation, the nightingale can be regarded as a happy image, but the cuckoo always appears in poems as a sad image. And there is a close relationship between the nightingale and romanticism school in the western literature while the cuckoo can be cited by every school in Chinese poems. xix Bibliography A. S.

Still wouldst thou sing, and I have ears in vain To thy high requiem bee a sod. (Gu Zhengkun, 2021: 168) In this poem, “I” (the poet) and “thou” (the nightingale) are two pletely opposite images. One is melancholy while the other is carefree. The poet is intoxicated by nightingale’s singing, whereas his ideas of death bee stronger. He is eager to “cease upon the midnight with no pain”. (Gu Zhengkun, 2021: 168) In reality, nightingale’s singing that stands for poet’s singing symbolizes the eternal enjoyment in fantasy. Nightingale in this poem does not imply pure happiness. It just sets off poet’s melancholy and disappointment. This is a writing skill that expresses one’s sadness by describing a happy situation. It proves the nightingale has a double symbolic meaning. But in general, it is for conveying desolate emotion. Compared with it, the cuckoo’s symbolic meaning in Chinese poems seems to be paratively single. The Different Relationship Between the Images and the Schools In English poetry, the sad image not only appears in general English poem, but bees a vital feature of romantic poetry. The former, Christina Rossetti’s poem, “When I Am Dead, My Dearest”, is an example. Its several wellknown lines in it are: I shall not see the shadows, I shall not feel the rain。 the other is the nightingale which symbolizes joys and hope: …… Darkling I listen。 second, the relationship between images and schools are different. The Happy Image of Nightingale In Chinese poems, the symbolized meaning of cuckoo is single. It is used only to set off the sad situations. Generally speaking, it has no other functions. For example, Qin Guan wrote in “Treading on Grass” (《踏莎行》 )： Shut up in lonely inn, Can I bear the cold spring. I hear at lengthening sunset homebound cuckoos cry. （可堪孤館閉春寒，杜鵑聲里斜陽暮。 (Palgrave, F. T, 1928: 358) Apparently, Barnfield seems to describe cuckoo’s sadness. However, in fact he displays his loneliness and grief by using the image of nightingale. Besides its melancholic voice, that nightingale like singing at night puts more weight on its grievous meaning. That is because from ancient to modern times, night is always connecting with loneliness and silence. For example, Henry Wadsworth Longfellow has a poem describing the night: I heard the trailing garments of the Night Sweep through her marble halls! I saw her sable skirts all fringed with light From the celestial walls! …… From the cool cisterns of the midnight air My spi
