Li Bai and Du Pu, who scored the highest in poetry, sought the answer.

In terms of output, there are nearly a thousand poems by Li Bai now, but many of them have been lost. There are more than 1,400 poems handed down from ancient times by Du Fu, which are equivalent in number. In terms of quality, or more accurately, high-quality products, Li Bai's poems are more improvised than carved, so some poems appear loose in content, repetitive in subject matter and imprecise in rhythm. Apart from entertainment, most of Du Fu's poems have substance in speech, which can stand beating and scrutiny. Therefore, Wang Shizhen has a cloud: "Ten poems ago, Shaoling was more difficult to enter; After a hundred songs, purple is more annoying. "
