Many of Li Bai's poems show the idea of pursuing immortality and eating, drinking and enjoying in time;

Style:
Li Bai often uses exaggerated techniques and vivid metaphors to express warm and unrestrained feelings;
Du Fu often shows his deep sympathy for social reality with vigorous skills and profound thoughts.
Li Bai tends to be romantic, while Du Fu tends to be realistic.
Third,
Be good at genre:
Both of them can write poems of various genres, but Li Bai's seven-character poems and quatrains are the best, and Du Fu's metrical poems are the best.
Li Bai and Du Fu were the most famous and influential poets in ancient China. However, since the Tang Dynasty, people like to compare them, and some scholars compare them, so that many poetry critics have participated in the debate about which is better or worse for Du Li. After entering the 20th century, although Du Li's theory of advantages and disadvantages still exists in academic circles, people prefer to discuss the friendship with Du Li and the similarities and differences between Du Li's poetic thought and art.
