The third and fourth sentences of Han Yu's Chun Xue (Tang Dynasty) are very wonderful and vivid. Please analyze it briefly. What should I do, help?

On the surface, it is said that there is snow without flowers, but the actual feeling is: people can still wait for the late spring scenery, and see the figure of spring from the grass buds in February, but the snow can't wait, and it has become a riot, flying among trees and decorating themselves with spring scenery. The real spring in the future (flowers in full bloom) certainly makes people feel a little sorry, but this Chun Xue wearing trees and flying flowers still gives people the breath of spring! The poet was not disappointed or sorry for Chun Xue's flying flowers, but delighted. A poet who looks forward to spring, if there is no spring scenery in nature, he can change into a spring scenery. This is the beauty of three or four sentences, full of strong romanticism, which can be called a stroke of genius. "Disdain" and "wear the same clothes" describe how beautiful and spiritual Chun Xue is. The conception of this poem is very strange. Snowflakes are flying in the early spring, which was originally the truth that "there is no fragrance in the New Year, and the grass shoots in early February". However, the poet said that snow was flying because spring came too late. This writing style of turning cause into effect adds interest to this poem. The word "flying flower" turns the coldness of early spring into the excitement of mid-spring, tossing and turning, leaving readers at a loss as soon as they enter the mountain.
