Harmony of lake light and moonlight; The lake is bright and calm.
From the poem, we can not only see the beautiful landscape of Dongting, but also see the beautiful moonlight that night.
The poet vividly wrote the beautiful scenery of Dongting through appropriate metaphors. Compare the bright and calm lake to an unpolished mirror.
Compare the lake in the moonlight to a silver plate, and compare Junshan in the lake to a green snail.
