Du Fu's Appreciation of Ascending Heights is about 800 words.

[Tang] Du Fu's flurry of monkeys and birds returned to Bihu Baisha. 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. It is sad for apes to cry when the wind is high and the sky is high. There are birds hovering on the clear river and white beach. Endless trees are rustling leaves, and endless Yangtze River is rolling in. Sad to autumn, I feel that Wan Li has been wandering all the year round and has been sick all his life. Today, he is alone on the high platform. After a lot of hardships, white hair covers the temples, and poverty hangs a cup of sorrow. Appreciation: This poem was written by Du Fu in Kuizhou in the second year of Dali (767). At that time, the poet fell ill in Kuizhou on the bank of the Yangtze River. The whole poem tells the poet's complex feelings of wandering, old illness and loneliness for many years through mountaineering, which is impassioned and touching. Yang Lun praised this poem as "the first of Du Ji's seven-character poems" (Du Shi Jing Quan), and Hu Yinglin's "Poetry" is even more amazing, and it is the highest of seven-character poems in ancient and modern times. The first four sentences are about climbing mountains. The first couplet is right. Focusing on the specific environment of Kuizhou, the poet used the word "wind rush" to drive the All-China Federation, and from the beginning, he wrote a quatrain that has been told for generations. Kuizhou is famous for its many apes, and the canyon is famous for its windy weather. It is cool in autumn, but it is windy here. When the poet climbs the mountain, the sound of "high apes whistling" comes from the gorge, which means "the empty valley echoes, and the sorrow turns to leisurely" ("Water Classic Notes on the River"). The poet moved his eyes from the heights to the rivers and lakes, and on the background of clear water and white sand, he was dotted with birds dancing with the wind and never looking back. This is really a beautiful painting. Among them, the sky, wind, sand, Zhu, and apes scream. Birds fly, a match made in heaven, a match made in heaven. Not only the upper and lower sentences are correct, but also the sentences are self-correct, such as the above sentence "heaven" versus "wind"; "high" versus "urgent"; The following sentences of "Sha" versus "Zhu" and "Bai" versus "Qing" are full of rhythm. After the artistic refinement of the poet, fourteen words, each of which is accurate and appropriate, are all in name only. In words, "thank you for your axe" has reached a wonderful and difficult state. What is more noteworthy is that the word "Wei" in the first sentence is usually flat, but this poem is flat. Shen Deqian praised "two sentences still rhyme, but the style has changed" ("Tang Poetry"). This couplet embodies the typical characteristics of Kuizhou in autumn. The poet looked up at the endless rustling leaves and looked down at the endless rolling river. While writing about the scenery, he expressed his feelings affectionately. "Endless" and "inexhaustible" make "rustling" and "rolling" more vivid, which not only reminds people of the sound of falling trees and the surging Yangtze River, but also invisibly conveys the feeling that youth is fleeting: ambition is hard to pay. Through the gloomy and sad dialogue, it shows superb brushwork, and it does have the majestic momentum of "repairing the palace" and "pouring hundreds of rivers into the east". It is reasonable for predecessors to call it "a unique step in ancient and modern times" and "a change in sentence". The first two couplets tried their best to describe autumn scenery, and it was not until the necklace that the word "autumn" was pointed out. "Alone on the stage" shows that the poet looks down from a height and closely connects the eye scene with the heart. Frequent visitor points out the poet's wandering life. "One hundred years" means a limited life, here refers to the twilight. The word "sad autumn" is written very painfully. Autumn is not necessarily sad, but when the poet witnessed the desolate and magnificent autumn scenery, he couldn't help thinking of his own exile, the old, the weak and the sick, so he gave birth to infinite sadness. The poet summed up the feelings of a long-time guest who is most likely to be sad in autumn and love to go on stage alone, which makes people deeply feel his heavy emotional pulse. The "Wan Li" and "Centennial" of this pair of couplets are the same as those of the last pair. "Boundless" and "endless" also have the function of mutual echo: the poet's travel worries and loneliness, like fallen leaves and rivers, are pushed and driven away endlessly, and emotion and scenery blend into one. At this point, the poem has given the general meaning of homesickness, increased the content of long-term loneliness, increased people's feelings of mourning for autumn and suffering from illness, increased the sigh of Wan Li and others leaving home in their twilight years, and made the poem more profound. There are five or six sentences at the end. The poet suffers from hardship and poverty, worrying about the country and the people, and his hair is getting gray. In addition, because of illness and alcohol deprivation, it is even more difficult for them to let go. The poet's ambivalence is easy to understand, because he was eager to climb high and see far, but now he provokes hatred for no reason, adding to his sorrow. The first six sentences are "flying", and here "soft and cold, infinite sadness is beyond words" ("Poetry"). The first half of the poem describes the scenery, the second half is lyrical, and the writing style is different. 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. It should only be vivid and vivid, so that readers can supplement it with imagination and express their feelings in triplicate, starting from two aspects: vertical (time) and horizontal (space), and writing from a foreign land to a sick and disabled life. 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 hurt the country jumped from the page. 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 they will never speak" It is natural to win the reputation of "masterpiece" (see Hu Yinglin's poem).
