It uses the Tang Dynasty poet Li Shangyin's "Two Gifts for Generations", an allusion about the separation of two lovers. "Always sweep spring mountains with eyebrows and eyebrows" means that a woman's eyebrows should be painted curved, like distant mountains in spring. The eyebrows represent the sadness in the woman's eyebrows, and it is written about a girl's separation sorrow.
The original sentence is:
Upstairs, my desires are resting at dusk, and the jade ladder is hooked in the middle of the moon. The plantains do not show their lilac knots, but they all face the same sorrow in the spring breeze.
The sunrise in the southeast shines on the tall buildings, and the people upstairs are singing Shizhou. I always sweep my eyebrows away from Chunshan, and I don’t know how much sorrow it brings.
The banana heart has not yet opened, and the cloves have not yet been resolved. They are both sad towards the spring breeze.
The sun rises in the southeast and shines on the tall buildings, and the people upstairs who are sad about separation sing "Stone Island". Even if the eyebrows are like spring mountains and the spring mountains are like eyebrows, I don’t know how much sorrow I have to endure?
Extended information:
The first part of Li Shangyin's "Two Poems as Gifts" is about the sorrow of separation at dusk. The second article describes the heroine's infinite sadness when she climbs the stairs in the morning. The first sentence is an adaptation of an ancient Yuefu poem. There is no person in this sentence, but there are people inside. You can imagine that the heroine is standing by the building facing the sunrise with sorrow. The second sentence specifically describes the sorrow of separation and the heroine singing sadly, full of hatred. A song of resentment, two sentences with picturesque scenes.
The third and fourth sentences focus on the heroine’s frown. The heroine's eyebrows are described as being like green mountains. The shape of the green mountains is originally used to describe the shape of the eyebrows, and it is used to describe the frowning state of the eyebrows. This is not the heroine's intention. However, the poet wrote the heroine intentionally, that is, she deliberately used indigo to paint her eyebrows to look like green mountains, and the next sentence started from the green mountains and came up with a new meaning, which made the poem twists and turns and full of meaning.
Even if this Liren painted his eyebrows like green mountains, he could not tolerate much sadness. The frown turned into a green mountain-like eyebrow that could not tolerate sadness. It all came out of nature. Looking from a tall building, you can immediately see the green mountains. The shape of the green mountains resembles the heroine's eyebrows. The poet became interested in writing through clever association. Then he coined this famous line about sorrow.
