Ask Li Bai Du Du Fu Bai Muju Yi Sushi Yang Wanli Xin Qiji Li Shangyin and others what they need to know when appreciating poetry.

An important content of Li Bai's poems is to expose and attack the dark politics at that time before the catastrophe; An important content of Du Fu's poems is to reflect the worries of the country and the people after the disaster. Li Bai wrote about Ren Xia, seeking immortality and learning Taoism, writing about the magnificent mountains and rivers of the motherland, and expressing personal frustrations. What he reflected most deeply at that time were the poems that exposed and attacked dark politics. Du Fu also wrote about the magnificent rivers and mountains of the motherland, expressing personal injustice and exposing and criticizing dark politics. He reflected the most touching poems describing the disparity between the rich and the poor, war disasters and people's sufferings at that time. The broad picture of social life reflected in those poems is unprecedented. He is called "the history of poetry" for no reason. Li and Du's poems are not only very different in subject matter, but also very different in creative methods. Yuan Hongdao in Ming Dynasty pointed out that Li Bai made good use of space and Du Fu made good use of reality. Li Bai's poems and songs have a clear and unrestrained beauty, while Du Fu's poems are characterized by depression and frustration.
