Untitled

Don

It was a long time ago that I met her, but since we separated, the time has become longer, the east wind is blowing and a hundred flowers are blooming.

Silkworms in spring will weave until they die, and candles will drain the wick every night.

In the morning, she saw her hair cloud changing in the mirror, but she bravely faced the cold of the moonlight with her evening song.

There are not many roads to Pengshan. Oh, Bluebird, listen! -Give me what she said! .

Translation:

The opportunity to meet each other is already very rare, and it is even harder to separate when leaving; Besides, in late spring, flowers are wilting.

Spring silkworms can't finish vomiting until they die; After the candle burned to ashes, the tears kept running dry.

Dress up and look in the mirror in the morning, only worried that the clouds will change color easily; If you can't sleep alone in the long night, you must feel the cold moonlight.

Penglai Mountain is not too far from here, but there is no road to cross. Jade bird, please go for me.

Untitled Appreciation is a love poem by Li Shangyin, a poet in the Tang Dynasty, whose theme is the separation of men and women. Taking the word "don't" in the sentence as the full text, this paper describes the pain of a pair of lovers' parting and their yearning after parting, and expresses their sincere lovesickness. But it also reveals the poet's political frustration and spiritual boredom, full of sadness, and expresses his great love and deep yearning for his lover through myths and legends. This poem incorporates the poet's personal life feelings.

This poem expresses the love psychology in a feminine style. It contains burning desire and persistence in sorrow, and its emotional realm is profound and rich.

This poem is full of pain, disappointment, lingering and persistent feelings from beginning to end. Every couplet in the poem is a reflection of this emotional state, but the specific artistic conception of each couplet is different. They repeatedly show the complex emotions throughout the poem from different sides, and at the same time reflect the psychological process with this complex emotion as its content vertically with their close connection. This continuous, implicit and profound lyricism successfully reproduces the deep affection in my heart.
