Shi Hu and Li made a brief appreciation of this poem from the artistic technique.

This is one of Du Fu's famous new poems "Three Officials". In the spring of the second year of Gan Yuan, Tang Suzong (759), Du Fu, then 48, was demoted from Zuo Shiyi to join the army in Sigong, Huazhou. He left Luoyang, passed through Xin 'an, Tongguan and Shi Hao, and spent the night in Huazhou, where the people were miserable, which caused a strong emotional shock to the poet.

At that time, the Tang Dynasty concentrated Guo Ziyi and others on riding two hundred thousand nine times, claiming to be six hundred thousand, and surrounded An Qingxu in Yecheng. Due to the tight war, the Tang Dynasty recruited soldiers everywhere to supplement its troops. At this time, Du Fu was traveling westward from Xin 'an County and living in Shihao Village. He met officers and men who arrested people late at night, so he recorded what he saw and heard and wrote this immortal poem. This poem depicts the brutality of officials, and reflects the profound disasters brought to them by the An Shi Rebellion and their own painful feelings. This five-character ancient poem is not long, with 24 sentences 120 words, and its content is very rich. It takes "seeing and hearing" as a clue, and goes deep step by step in chronological order, from dusk to night to long night to dawn, from lodging to farewell, to the police arresting people and tracking the old woman at night; Escape from the old man over the wall and sneak back afterwards; From the poet's lodging at dusk to his farewell at dawn, the whole story has a beginning, a development, a climax and an ending, and the plot is complete and quite tense. The beginning and end of the poem are narrative, with dialogue in the middle, and there are as many as five or six moving characters. The poet skillfully told the tragic experience of her family through the mouth of the old woman. The poet's narrative and the simple words of the old woman echo everywhere, closely linked, and the levels are very clear.

The poet reflected the truth and truth, hid the question and answered it, but only wrote the old woman's cry, wrote the subtext and voice-over from the cry, and integrated the image of the poor official into the "preface" of the old woman, which had an inexhaustible realm. The poet wrote the old woman's crying in plain language, without using any allusions, which was very suitable for the old woman's tone. With the repeated rhyme of the content, he formed a rhyme of deep grief and indignation, old age, singing three sighs and cadence, which made the depression and depression reach the extreme.

The whole poem describes feelings and events, except "what makes an official angry", which reveals his love and hate a little, and describes objective things. Here, through novel and ingenious artistic conception, the poet melts rich content and his own feelings into concrete images and pours them into objective narratives, so that things themselves can directly infect readers and stories themselves can reveal the poet's love and hate. This artistic technique of writing emptiness with reality, supplementing emptiness with reality, and making each other interesting makes the whole poem appear concise, concise and rich in connotation.
