This poem expresses the author's concern for the country and the people, his patriotism and his sympathy for the people in the north.
Lu You was a patriotic poet in the Southern Song Dynasty. Facing the era of drastic changes when the motherland was divided, he had early ambitions to serve the country. In his middle age, he joined the army in the southwest. The magnificent real world and the enthusiastic battlefield life greatly broadened his poetic realm. Just as he recalled in "Shi Zi Dun", "I started to realize something in my middle age, and gradually wanted to see the grandeur"; as he said in "Reading Poetry Manuscripts on the Night of September 1st and Composing Songs with Impressions", "The poet suddenly saw Samadhi, and Qu Jia was there. Eyes are on the Yuan calendar; heaven’s secrets and cloud brocade are used by me, and the beauty of tailoring is not a knife or ruler.” Naturally, those who play with half-swallowing and half-sucking skills can't see the majestic rainbow and the magnificent clouds. In his later years, he retreated to Shanyin, but his ambition never faded, his iron horse was glacial, and he often fell into dreams. "The old man is in trouble, and his ambition is thousands of miles." He was infinitely indignant at the loss of the Central Plains, infinitely concerned about the fate of the people, and infinitely worried about the Southern Song Dynasty's ruling group's attempt to maintain peace and harm the country. The hatred is poured out freely in this four-sentence poem.
