Dou E Yuan by Guan Hanqing in Yuan Dynasty tells the story that Dou E was framed by hooligans, misjudged and sentenced by the government, which truly and profoundly reflects the extremely dark, cruel and chaotic tragic times of China society under the rule of Yuan and Mongolia. This also profoundly reveals the social and political situation at that time through literature from another side. Su Xun, an essayist in the Song Dynasty, wrote a famous historical article "Six Kingdoms", which incisively discussed the reasons for the demise of Qi, Chu, Yan, Han, Zhao and Wei at the end of the Warring States Period, and satirized the present with the help of the past, aiming at warning the Northern Song Dynasty to learn from the historical lessons, change its policy of compromise and surrender to Qidan and Xixia, and not repeat the historical mistakes. Su Xun's sense of hardship and foresight made him see that the main reason for the demise of the Six Kingdoms was "the disadvantages were in Qin", and repeatedly demonstrated this central argument. Can't this reflect the close relationship between literature and politics?
