This poem is about a woman's feelings in the boudoir overnight, with delicate lyric and ingenious structure. The heroine in this article is troubled by her husband's long journey. The timed clepsydra sounded the sound of "Tintin" dripping in the quiet night, drop by drop, as if they were beating her heart. She listened, counted and thought anxiously, why is the night so long? She looked bored at the sky, the endless light clouds in the sky moved slowly, and the moon was sometimes covered and sometimes exposed. What Sifu saw and heard during her insomnia aroused and aggravated her sadness and loneliness. In the long sleepless night, autumn insects in the dark have been singing all night. Listening, it suddenly occurred to her that it was time to prepare warm clothes for her husband. The word "Tong Xi" in the third sentence clearly refers to the long time of writing autumn insects, but actually implies that Sifu stayed up all night. The word "forced" is used wonderfully, which not only "forced" the cry of autumn insects, but also "forced" the homesick woman to think of her husband's cold clothes, which naturally led to the lyric last sentence. The fourth sentence "I didn't send Murphy cream when I asked for clothes" is a monologue thinking about my wife's heart. Is she pleading with God, or is she giving orders directly? Call for help or command, in short, from this childish language, we can see her infinite affection for her husband. This poem is the finishing touch. Although the first three sentences are mainly about feelings, without the topic of the last sentence, readers can neither understand the feelings in the scene, nor know what feelings are mainly expressed in the whole poem and who is the protagonist in the poem. The last sentence sounds deeply homesick, which makes people suddenly realize that what the poet wants to play in Autumn Night is just the lingering feelings of homesickness.
