When the sun goes down, the river rustles and the river turns red?

"A setting sun in the water, half river rustling, half river red" is written in autumn.

"A setting sun is sprinkled in the water, half the river is rustling and half the river is red" comes from Bai Juyi's poem Ode to Mujiang.

Mujiangsong

Tang Bai Juyi

A sunset gradually sank into the river, half green and half green.

On the third night of September, the dew is like a pearl and the moon is like a bow.

The third day of September in the poem is autumn.

Ode to Mujiang is one of Bai Juyi's "miscellaneous poems". The beauty of the whole poem lies in taking two beautiful pictures of nature and combining them. One is the gorgeous scene of the sunset reflected on the river, and the other is the hazy night when the crescent moon rises and the dew is crystal clear. Both of them have their own beautiful scenery, and it is even more exciting to watch them together. Poets also add metaphors to their poems appropriately to make the scenery more vivid. Because this poem permeated the relaxed and happy liberation mood and personality of the poet after he was forced to stay away from the imperial court, the whole poem became the artistic carrier of the poet's aesthetic psychological function in a specific situation.

The first two sentences are about the river at sunset. "A sunset is spreading in the water". The sunset shines on the river, but it means "spreading" instead of "taking pictures". This is because the "sunset" is very close to the horizon, almost touching the ground, and it really looks like it is "paved" on the river. The word "shop" also appears euphemistic and gentle, describing the unique softness of the autumn sunset, giving people a cordial and leisurely feeling. "Half the river is rustling, half the river is red", the weather is clear and windless, the river flows slowly, and there are tiny ripples on the river. The part that receives more light shows "red"; Where there is little light, there is dark blue. The poet grasped the two colors on the river, but showed the scene that the river was sparkling at dusk and the color changed rapidly in the sunset. The poet was intoxicated and put his happiness in the description of the scenery.

The last two sentences are about the night scene when the new moon rises. The poet lingered until the early moon rose, the cool dew fell and a better realm appeared in front of him. The poet leaned down and saw the grass by the river covered with crystal dew. Dewdrops on the green grass are inlaid on the green grass like pearls. With the metaphor of "real pearl", not only the roundness of dew is written, but also the luster of dew shining under the new moon. When the poet looks up again, a crescent moon rises, just like hanging a delicate bow in the blue sky. The poet condensed two scenes in heaven and earth into a poem-"Dew is like a pearl, and the moon is like a bow". From a crescent moon bent like a bow, the author remembered that it was "the third night of September", and could not help but blurt out his lovely praise for it, expressing his feelings directly, pushing his feelings to a climax and causing waves in his poems.
