Take "Climbing Mount Tianmu in a Dream" and "Chanting 500 Words from Beijing to Fengxian" as examples, and talk about the different impressions of Li Bai's and Du Fu's poems.

Li Bai was passionate and Du Fu was depressed and frustrated. Li Bai is a romantic poet, and Du Fu is critical of reality. Li Bai wrote more romantic poems. "Silent Night Thinking" and "Ah, how can I bow and scrape to those high-ranking officials whose sincere faces will never be seen?" show their spirit of being unmoved by fame and fortune. "Three Farewells" reflects his dissatisfaction and anxiety about reality and pays attention to the suffering of people's lives.
