What is the poem that expresses the author's ambition to cross the ocean?
"Since ancient times, no one has died in life, leaving Dan's heart to shine." Ding Yang Crossing Zero was written by Wen Tianxiang, a patriotic poet in the Song Dynasty, when he was arrested by the Yuan Army. At that time, the Yuan Army tried to make Wen Tianxiang surrender with high officials and generous salaries, but Wen Tianxiang was unmoved by high officials and generous salaries and would rather die than surrender. When the ship escorting him crossed Lingdingyang, he felt it and broke out this poem. Among them, the first few sentences are all regrets and pains about the country's demise, while the last two sentences are the lofty aspirations of the conquered people. I personally like this poem very much.
