The classic sentence in Du Mu's "Walking Out of the Mountain" is "Stop and sit in the maple forest late, and the frost leaves are red in February." The poet was pleasantly surprised to find that under the sunset glow, the maple leaves were about to drip and the forest was dyed. It's full of colorful clouds, such as bright rosy clouds, which are more fiery and gorgeous than the spring flowers in February in Jiangnan. What is commendable is that the poet saw the vitality of autumn as spring through this piece of red, which made Lin Qiu present a warm and vibrant scene. The fourth sentence is the center of the whole poem, written by the poet with strong colors and coherent brushwork.

The seemingly lyrical narrative of "stopping to sit in the maple grove late" actually plays a role in setting off the scenery: the poet who stopped to watch, Tao Ran drunk, became a part of the scenery, and with this scene, the charm of autumn colors became more obvious.
