The first part of this word is about the scenery of Dongting Lake under the moon, which highlights its clarity. "Dongting grass, near the Mid-Autumn Festival, is even more disgraceful."

But sensitive poets can feel the color of the wind from the changeable situation. Li Bai's "Lushan Ballad": "I climbed to the top. I look around the world, and the great river is gone forever. The yellow cloud was blown away by the wind for hundreds of miles, and a snow peak was surrounded by a vortex with nine times the current. " Then Wan Li and Huang Yun changed the color of the wind. Zhang Xiaoxiang said here that "there is no wind at all", which shows that there are no clouds on the Wan Li in Dongting Lake, and the water waves are quiet, which makes people fascinated by cold and natural reading.
