Is it a weather proverb that the setting sun spreads half a river in the water, whispering half a river and blushing half a river?

Yes, it is the cold dew, the annual 17 solar term. This year's cold dew season begins on June 8 10 (today) and ends on1October 23 10.

The hymn of Twilight River

Tang Bai Juyi

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

The loveliest thing is the ninth day of September. The bright pearl's bright crescent moon is shaped like a bow.

China's traditional summer calendar (lunar calendar) divides a year into 24 solar terms. Cold dew is the17th solar term every year. This year's cold dew season starts from1October 8th (today) and ends on1October 23rd.

During this period, the temperature in most parts of China will be much lower than that in the Millennium. In the cold dew season, the dew is heavier and the temperature is colder, but the rainfall decreases. The autumn crops are almost ripe.

The poet chose two groups of scenery to describe the period from the setting of the sun to the rising of the new moon. The first two sentences are about the river at sunset. The sunset spreads in the water. The setting sun shines on the river, but it says "spread" instead of "take pictures" This is because the setting sun is close to the horizon and almost touches the ground.

Come on, it's really like lying on the river, very vivid; The word "shop" is also gentle, which says the softness of 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 over and looked at it: Hehe, the grass by the river is covered with crystal dew. Dewdrops on the green grass look like pearls embedded in it! 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. Look 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 the 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 the poetry circle.

What a harmonious and peaceful artistic conception the poet created by describing the two visual images of "dew" and "moon"! With such a novel and ingenious metaphor, it is amazing to describe and color nature in detail. There seems to be a lack of time between describing the sunset river and praising the moon dew, but the night on the third day of September invisibly connects time, which means that the poet enjoys it from dusk until the moon is exposed, which contains the poet's joy and love for nature.

This poem was written by Bai Juyi on his way to Hangzhou as a secretariat in the second year of Changqing (822). At that time, politics was dark, and the struggle between Niu and Li was fierce. The poet tasted the taste of being an official and asked to go abroad. This poem reflects the poet's relaxed and happy mood after leaving the court. What I saw in the tour was all sung casually, with a fresh and natural style, which gave people a beautiful enjoyment after reading it.
