From "When have the spring flowers and autumn moon arrived, and how much do we know about the past?" I can feel the sadness, indignation, and regret in Li Yu's heart as he fell from a majestic monarch to a prisoner of the Southern Tang dynasty; I can feel the author's deep longing for his homeland from the phrase "Last night, there was an east wind in the small building, and my homeland was unbearable to look back on in the moonlight."; The spirit of serving the country in "Waiting for the beginning, tidying up the old mountains and rivers, facing the sky." is the spirit of heroes, the soul of heroes... Living in the new era, although we do not need to worry about the downfall of our country, we should still have a patriotic heart. In the past, "serving the motherland" was a sacrifice in the battlefield, but now the only thing we can do is to study cultural knowledge well, break through ourselves in our work positions, and contribute to the future development of our motherland.
