What does "Dapeng rises with the wind in one day and soars into Wan Li" mean?

Moral: It's windy in Dapeng, soaring to the height of Wan Li.

Poetry: Li Yong and Li Bai in Tang Dynasty.

Dapeng rises with the wind one day and soars into Wan Li. If the wind weakens, it can still lift away the turbulent current.

When the world saw my unchanging tone, it sneered at all my big words. Fu Xuan can still fear the afterlife, but her husband can't be young.

It's windy in Dapeng one day, soaring to the height of nine Wan Li. If you stop when the wind stops, it will have enough power to lift the sea water out of the sea. When people see that I like to say strange things, they all laugh at my big talk. Confucius also said that man is born to be feared, and a gentleman cannot despise young people!

Extended data background: This poem is the work of Li Bai in his youth. From 7 19 to 9 (72 1), Li Yong was the secretariat of Yuzhou (now Chongqing). According to the history books, Li Yong was "quite conceited" (Biography of Li Yong in Old Tang Dynasty). He was conceited and had a good reputation, but he had reservations about being young and backward. Li Bai was dissatisfied with this, and when he left, he wrote this poem "Li Shangyong" in a rather rude manner to show his return.

Appreciation: Poetry expresses Li Bai's lofty aspirations and strong desire to use the world by depicting and praising the image of Dapeng, and expresses his dissatisfaction with Li Yong's attitude of looking down on young people, showing Li Bai's spirit of being brave in pursuit, confident and conceited, and not afraid of vulgarity. Young Li Bai dares to challenge big shots and is full of the spirit that newborn calves are not afraid of tigers.
