Do you understand the meaning of Liu Yuxi's poem "Langtaosha"?

Langtaosha means

It means, don't say that gossip is as deep as a torrent, and don't say that people who have been relegated will sink forever like mud. Gold panning needs repeated filtering. Although it is hard, only when the precipitation is exhausted will the shining gold be revealed.

The poet has been demoted many times, but he is tenacious in fighting spirit, optimistic in spirit, broad-minded and fearless. Although he has gone through hardships in the remote relegation office, he can finally show that he is not useless waste sand, but bright gold. The poem sums up his deep feelings from his own experience through concrete image metaphors, and firmly believes that those who have been victimized by slanderers will know the truth one day.

Langtaosha soup Liu Yuxi's Nine Tunes, the Yellow River and Wan Li Sand, swept across the world. Now they go straight to the Milky Way and go to Penny Weaver's house. Note 1. Langtaosha: the name of a tune in the Tang Dynasty. 2. The waves are abundant: the Yellow River is silted and the wind and waves are rolling. Tianya: Tianya. 3. Galaxy: The ancients thought that the Yellow River and the Galaxy were interlinked ... They were only allowed to meet once a year on the seventh day of the seventh lunar month. The winding Yellow River is very long, carrying a lot of yellow sand. The Yellow River is choppy, surging out from the horizon. Now I'm going straight to the Milky Way against the wind and waves, and I'm going to the door of the Cowherd and the Weaver Girl. Appreciating this poem, written in Kuizhou, is a political expression poem of folk songs and the first poem in Jiulangsha. A magnificent picture of galloping thousands of miles. Nine Songs describes the twists and turns of the Yellow River in an exaggerated way. Looking from the end of the world, the long history of the Yellow River is fascinating, similar to the sentence "How does the water of the Yellow River move out of heaven and into the ocean, never to return" in Li Bai's Into the Wine. The last two sentences use Zhang Qian's allusion to the search for Heyuan for Emperor Wu and the Cowherd and the Weaver Girl across the Milky Way, and gallop through the imagination, which indicates that he will face storms and Wan Li.
