One or two sentences in the poem form a natural antithesis, which truly reproduces the process of touching homesickness from the comparison and connection between geography and time. The word order of these two sentences is reversed: originally, I saw the azaleas in Xuancheng first, and then I thought of the Zigui birds in Shu, but the poet reversed it, writing the virtual scene in memory first, and then writing the real scene in front of me. In this way, the thought of the old country is placed in a prominent position, indicating that the thought of the old country is trapped in the heart, and once it is aroused, it will be extremely bitter and intense. However, poets tortured by homesickness can't go back to their hometown now. In his youth, he "fought bravely to serve the country, resigned from his relatives and traveled far away" and wanted to realize his grand ambition in the vast world outside his hometown. I want to retire and return to my hometown. Unexpectedly, his grades are nothing, and the old man has fallen to this point. He felt that he had no face to meet the elders in Shu. What's more, Li Bai is now trapped in Xuancheng, dragging his old and sick body and unable to embark on a journey. A poet who has been wandering all his life, in the end, not only has no home in politics and career, but also has no sustenance on him. Looking at my hometown thousands of miles away, I can imagine the sadness in my heart. Three or four sentences, followed by one or two sentences respectively, further enhanced the deep homesickness. The first sentence says "I have heard of it", and the third sentence emphasizes the truth: Zigui bird is commonly known as heartbroken bird, and the poet's sorrow is broken inch by inch. At the end of the period, the seasons are distinct, and the second sentence adds the words "March March"; The word "Memories of March 38" highlights the theme of homesickness, integrating the blooming of azaleas, the sad cry of Zigui and the heartbroken pain of the poet, and enveloping the whole poem with boundless sadness. Three or four sentences in the poem seem to be antithetical, but they are not quite correct. The poem connects the words "one" and "three" respectively, which makes people feel extremely sad and painful when homesickness strikes. [
