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. Young Li Bai dared to challenge big shots, and when he first debuted, he was full of the spirit of not being afraid of tigers.
This poem was written by Li Bai when he was young. From 7 19 to 9 (72 1), Li Yong was the secretariat of Yuzhou (now Chongqing). When Li Bai visited Chongqing, he paid an audience with Li Yong. Li Yong was unhappy because he was informal and talked about Wang Ba. 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.
