Appreciation of Huang Tingjian's Second Rhyme Pear

Peach blossoms are all red, not as good as natural jade. Always looking at the dust and leaning against the wall.

(Note) Jade Zuo Rong: Describe pear flowers as white as jade. Cage Moon: Covered by moonlight

On the surface, this poem celebrates the whiteness of pear flowers, but in fact it celebrates the nobility and purity of pear flowers that are not stained with dust.
