How do the three ancient poems Song Qing, Painting Chrysanthemums and Xue Mei express the poet's feelings respectively? What's the difference in expression?

Song Qing shows the poet's indomitable tenacity, Painting Chrysanthemums shows the poet's quality of leading an honest and clean life and his ambition to pursue a quiet life, and Xue Mei, by praising Mei, shows the poet's attitude of keeping a pure personality and pursuing a perfect life.

Song Qing adopts the technique of line drawing, which naturally presents the nobility of Song Qing. It belongs to visual presentation.

"Painting Chrysanthemum" uses the description of chrysanthemum form, integrates its own inner feelings into it, and expresses it through the language of poetry, which deepens the connotation of chrysanthemum. It belongs to sensory presentation.

By analogy, Xue Mei expressed her love for Xue Mei from the sense of smell, and metaphorically expressed her lonely attitude towards life. It belongs to olfactory presentation.
