The poet used the word "difficult" twice in one sentence, and the appearance of the second word "difficult" gave people a slight sense of suddenness because of repetition, which made the whole poem interlocking and made the parting pain of reunion after a long separation particularly profound and lingering because of the low expression; This sentimental modality is not easy to understand in such a straightforward narrative as "Don't be easy to get". This lyric hero is already so sad, but facing the scenery in late spring, of course, it makes her sad. In late spring, the east wind is weak, flowers bloom and fall, and the beautiful spring is about to pass away. There is nothing that human beings can do about it. Their own misfortunes and mental pains are like flowers that wither with the passage of spring, because beautiful things are destroyed, which makes people feel endless disappointment and regret!
