If you don't touch the mud, you won't be evil. -Excerpt from "Ailian Shuo" Zhou Dunyi used lotus flowers as a metaphor for a gentleman. He walked out of a vulgar environment, but he was able to maintain his pure quality and was not infected by bad habits. The sword front comes from sharpening, and the plum blossom fragrance comes from bitter cold-from the diligent article "Warning the World". Interpretation: the sword front comes from sharpening, and the plum blossom fragrance comes from the cold winter. Yu Yi: It takes constant efforts, cultivation and overcoming some difficulties to have precious qualities or beautiful talents. I quit my job and go home, just like a flower falling from a branch, but this is not a heartless thing. It can be turned into the soil of spring and can also play a role in nurturing the next generation. Gong Zizhen interprets Yi Hai's Miscellaneous Poems: Falling red refers to flowers separated from branches, but it is not something without feelings. Even if it turns into spring mud, it is willing to cultivate beautiful spring flowers to grow. Not for the unique fragrance, but to protect the flowers. It shows that although the poet is divorced from officialdom, he still cares about the fate of the country and never forgets his ambition to serve the country, which fully expresses the poet's strong feelings.
