On the surface, this poem seems as if Du Fu is trying to persuade Li Bai to concentrate on alchemy and seek immortality like Taoist Ge Hong, not to waste time by drinking crazy songs, and why he should be bossy and dominate others. In fact, this poem by Du Fu has a moral: Li Bai despises powerful people, leaves in a hurry and is reduced to exile. Although he drinks crazy songs every day, he is not appreciated by the rulers; Although the heart is full of men, but why dominate? Although there are talents who help the world, how to display them? Du Fu's admiration is full of emotion and sadness. So he complained about his resentment, and even put forward a seemingly complaining inquiry in a rhetorical tone, but it was unfair. His feelings are not only for Li Bai, but also for himself.
This poem shows a crazy word and a proud word. Proud and rough, this is Du Fu's portrayal of Li Bai. In A Gift for Li Bai, the arrogant style, strength and tolerance are highlighted, and Li Bai's spirit and oh, how can I solemnly bow and scrape to the high official Hou Lu? This is the poetic eye and essence of this poem. It is not only in line with Du Fu's other poems praising Li Bai, but also vividly reveals Li Bai's character and temperament.
