The works express indignation at customs, persistence in ideals, and the will to die for one's ambition, which is in line with the spirit of "I won't regret dying nine times", "I will die innocent" and "I won't change even after disintegration" in Li Sao.

One of the most outstanding features of this poem is that there is a long paragraph in it. This passage describes the scenery of the Yuanshui River basin, which became the earliest excellent poem in China and had an impact on the creation of similar poems in later generations. The organic combination of scenery description and emotional expression in the poem has reached a perfect state.

The last paragraph uses phoenix, phoenix and vanilla to symbolize integrity and nobility; The metaphor of swallows, blackbirds and fishy smell is a metaphor of evil forces, which fully expresses the poet's deep feelings about the current society.
