From Yuan Heng's poem "Looking at Yu Fengxiang in Mogu Lake" in Tang Dynasty, it says: "The willow flowers bloom on the mountain, and the song of tall buildings is transformed." And the poem "Traveling to Shanxi Village" in the Song Dynasty: "There is no doubt about mountains and rivers, and there are other villages in the dark." In the past, it refers to the scene of colorful, lush trees and flowers, and later it refers to finding a way out and suddenly appearing a good situation.

Back to this word, in fact, intertextuality is used in the word, that is to say, there is a bright future. It means that willows and flowers (referring to flowers and plants) are obviously secretly embellished with each other. In other words, it's a bright future. If you don't quite understand, you can take a look at this sentence: "A general dies after a hundred battles, but a strong man returns after ten years." This sentence does not mean that the general died after many battles, but that he returned from ten years of fighting for a strong man. But the generals and soldiers returned after ten years of life-and-death war. This is intertextuality.
