Liu Yuxi is eager to return to a position where he can use his talents and make a difference, and he will not change his original intention of joining the world even if there are frequent evil waves. This shows the poet's indomitable and enterprising spirit.

Original poem: The Yellow River has nine bends and thousands of miles of sand, and the waves and winds are tossing it from the end of the world. Now we go straight up the Milky Way to the home of the Morning Glory and the Weaver Girl.

Interpretation: The Nine-Meander Yellow River meanders from a distant place, carrying thousands of miles of yellow sand along the way. Since you came from the sky, you seem to be flying straight up to the Milky Way high in the sky. Please take me up to the Milky Way and be a guest at the home of the Cowherd and the Weaver Girl.

Extended information:

Liu Yuxi used the bright, round and interesting tiger's eyes, and the oily green and spring-like appearance of the duck's head to describe the sparkling waves of Bianshui and Huaishui. Sparkling and green like emerald. Parrots who imitate others are very clever, but they can also attract resentment. There are waves in the river, so the boat cannot sail safely, and the waves and sand make it even more depressing.

The swallows rush to return to their homes, and the wives are still missing their husbands. The poet uses contrast to cleverly convey his helplessness of having a home and being unable to return. If someone is demoted and relegated despite no fault of their own, it is inevitable that they will feel unfair in their hearts. People often use brocade to describe the excellence of literary talent. The Zhuojin River is named after the Zhuojin River. After the brocade is washed in the water, it will become more bright and radiant. After experiencing relegation, the poet thought more clearly about life, and his creative talents were greatly stimulated.
