I ask questions at will and try to get rid of the stereotypes of my predecessors. "
2. In terms of style, Du Fu's poems are called "the history of poetry" because of his gloomy poetic style and his concern for the country and the people. His poems are characterized by archaism and rhythm, and have various styles. They accurately summed up his own work style with the word "depressed and frustrated", and focused on depression, which better expressed his thoughts of worrying about the country and the people.

From the environmental point of view, Du Fu lived in the historical period from prosperity to decline in the Tang Dynasty, and his poems mostly involved social unrest, political darkness and people's sufferings.
