Seek to write Du Fu's quality and epitaph.

Du Fu was concerned about his country and people, but he didn't meet his talents, while talented people couldn't display their talents and were determined to express their feelings in his poems. Even if you are displaced in the war, you can't let go of your compassion when you are old and weak. His poems inherited the system of "national style" and "Li Sao", including the rhythm of Shen Quanqi and Song Wenzhi; Simplicity spread to Su Weidao and Li Bai, surpassing Cao Zhi and Liu Xiyi in momentum; Yan Yanzhi and Xie Lingyun are lonely and lofty, while Xu Ling and Yu Xin are brilliant. He has all the advantages of ancient and modern times, and also has his own specialty as a scholar. But all this can't hide the lingering faint melancholy charm and the sad, lost and dissatisfied atmosphere in his poems.
