What is the name of youth for every interval with flower-like stripes?

Title: Jinse

Author: Li Shangyin [Tang Dynasty]

I want to know why my Jinse has fifty strings, and each string has a youthful interval.

Zhuangzi daydreaming, a saint, was bewitched by butterflies, and cuckoo crowed in the imperial spring.

Mermaids shed pearl-like tears on the moon-green sea, and the blue fields breathed their jade to the sun.

A moment that should last forever has come and gone before I know it.

Why do exquisite musical instruments have fifty strings, each of which reminds me of my youth? Zhuang Zhou danced in his sleep and turned into a butterfly, hoping that the emperor would entrust his hatred to Du Fu. Things change, the bright moon is in the sky, and Jiao Ren's tears are all beads; Lantian is sunny and warm, and you can see good jade and good smoke. Why do you want to recall this scene now? I just didn't know how to cherish it then.

Jinse is a poem by Li Shangyin, a poet in the Tang Dynasty. The title of the poem is Jinse, but it is not a poem about objects. It's just an untitled poem with the first word as the title according to the convention of ancient poetry. This poem is one of Li Shangyin's most difficult works, and the poet has always lamented that "a Jin Se is difficult to understand".

In his poems, the author recalled his youth, felt sad about his unfortunate experience, and pinned his feelings of sadness and resentment. He borrows a lot of allusions such as Zhuang Sheng's dream butterfly, cuckoo crying blood, tears in the sea, jade like smoke, etc., and uses metaphor and imagination to transform auditory feelings into visual images, and creates a hazy realm by combining fragments of images, so as to convey them with the help of visually perceptible poetic images. The whole poem is colorful, subtle and profound, sincere and touching.
