2. Li Shangyong is the work of Li Bai, a great poet in the Tang Dynasty, when he was young. By depicting and praising the image of Dapeng, this poem expresses Li Bai's great ambition and strong desire to use the world, and is very dissatisfied 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. The tone of the poem is straightforward, unprincipled and full of the spirit that newborn calves are not afraid of tigers.
