From which poem does "The Ape Sobs in the Wind in the Sky" come?

Ascending the Mountain is a seven-character poem written by Du Fu, a great poet in the Tang Dynasty, in Kuizhou in the autumn of the second year of Dali (767). The language of this poem is concise, the whole poem is dual, and one or two sentences are still correct, which fully shows that Du Fu's mastery and application of poetic language temperament in his later years has reached the realm of tact.

Original: In the wild wind in the vast sky, apes are sobbing, and birds are flying home on the clear lake and white beach.

The endless trees are rustling leaves, and the Yangtze River is rolling unpredictably.

Li in the sad autumn scenery, a wanderer all the year round, lives alone on the high platform in today's illness.

After all the hardships and hatred, the white hair is full, and the wine glasses are damaged.

The first half of the appreciation poem depicts the scenery, and the second half expresses the emotion, each with its own complicated writing methods. The first couplet focuses on describing the specific scenery in front of us, just like the meticulous brushwork of a painter, showing the shape, sound, color and state one by one. The second couplet focuses on rendering the atmosphere of the whole autumn, just like the painter's freehand brushwork, which should only be vivid and easy to understand, so that readers can supplement it with imagination. Triple expression of feelings, from vertical (time) and horizontal (space) two aspects, from wandering to sick and disabled. Quadrupling the number of white hair, protecting illness and abstinence from alcohol can be summed up as the hardship of the times is the root of poverty. In this way, Du Fu's feelings when he was worried about the country and the people and hurt the country were vividly displayed.

All eight sentences in this poem are correct. At first glance, the beginning and the end seem to be "wrong", and the chest and abdomen seem to be "wrong". After careful consideration, "every sentence in the article is law, and every word in the sentence is law." Not only "the whole article can be taught", but also "choose words and make sentences", "people in ancient and modern times dare not speak and will never speak" It is natural to win the reputation of "masterpiece" (see Hu Yinglin's poem).
