The Zero Crossing and Ding Yang is a poem by Wen Tianxiang, Minister of Song Dynasty. This poem begins with two self-narrative life experiences, thinking about the present and recalling the past, with many feelings; Zhuan Xu's two sentences have unfolded and profoundly described the reality of the country's destruction from two aspects: the country and the individual. The second sentence of the necktie recalls the different situations and moods of the past and the present. I used to be afraid of worrying about the country and people on the beach, but now I feel lonely in the ocean. The last sentence, based on death and ambition, is the author's choice of his own destiny without hesitation. The whole poem shows impassioned patriotic enthusiasm, lofty moral integrity and the outlook on life, which is a lofty expression of the traditional virtues of the Chinese nation. The style is magnificent, the emotion is sincere and natural, the language is neat and delicate, vivid and vivid, and the meaning is rich.
