The poet of "Looking at Dongting Lake" painted a beautiful picture of Dongting Lake in autumn with brisk brushstrokes, expressing the author's love for the beautiful scenery of Dongting Lake. "Silver Plate" refers to Dongting Lake and "Green Snail" refers to Junshan Mountain. Metaphorical rhetoric is used here. The poem describing the beauty of Dongting Lake is: the lake is full of moonlight, and the mirror on the pool surface is not polished.
