Looking at the scenery of Dongting in the distance, a green snail in a silver plate told me the scene described in the poem.

From a distance, Junshan Mountain in Dongting Lake is as green and clear as the lake, just like a delicate silver plate with a green snail on it.

From the perspective of moonlit night, the poem gives a panoramic view of Dongting Lake in autumn through strange imagination and novel and appropriate metaphors, and vividly depicts the ethereal, ethereal, quiet and harmonious scenery of Dongting Lake in autumn night.
