I wonder why my inlaid harp has fifty strings, each with its flower-like fret an interval of youth.
the sage Chuangzi is day-dreaming, bewitched by butterflies, the spring-heart of Emperor Wang is crying in a cuckoo.
mermen weep their pearly tears down a moon-green sea, blue fields are breathing their jade to the sun.
Interpretation of the whole poem: Jinse somehow has fifty strings, each of which reminds people of Feng Hua's youth. Zhuang Zhou was puzzled by dreaming of butterflies at dawn, and Wang Di entrusted the grief of hurting spring to Du Fu. The moon pearl is full of tears and sinks into the sea, and the warm jade turns into mist and dissipates in Lantian. Which of these sentimental feelings is recalled now, or it was already confusing at that time.
expanding information
this poem is one of the representative works of the poet Li shangyin. The title of the poem is "Jinse", but it is not an ode to things. It is just an untitled poem with the first word as the title according to the practice of ancient poetry. This poem is one of Li Shangyin's most difficult works to solve, and the poet has always lamented that "a Jinse is difficult to solve people".
In the poem, the author recalls his youth, feels sad about his unfortunate experiences, and entrusts himself with feelings of sadness and resentment. He borrows a lot of allusions such as Zhuang Sheng's dream butterfly, cuckoo's crying blood, tears in the sea, good jade and smoke, and uses metaphor and imagination to transform auditory feelings into visual images, creating a hazy realm by combining fragments of images.
thus, with the help of visual and sensible poetic images, it conveys its sincere, strong and profound thoughts. The whole poem is colorful, subtle, profound, sincere and touching.
