He really experienced the ups and downs of the Tang Dynasty, and the Anshi Rebellion brought heavy losses to the Tang Dynasty. He really realized it in his wandering.
Despite many ups and downs, Du Fu never forgot to care about the country and the ordinary people. He linked his miserable life with this troubled country, and together they became the main theme of Du Fu's poems, so his poems have the reputation of poetic history, which is one of the reasons for the gloomy characteristics of his poems.
His poems contain the most vivid images of the country's suffering, and the emotions in his poems are concerned about the country and the people. Such emotions are deep and desolate in the pursuit of art. Du Fu once said of himself, "I am lonely for human nature, and my words are not surprising."
He is good at using various styles to make his poems more solemn and powerful in rhythm and intonation, and sometimes he even deliberately breaks the rules of meter, which makes the poems lose their superficial balance and harmony, thus gaining a kind of strength and facilitating the expression of his deep and strong feelings. Summary:
Therefore, many of his poems have a sense of frustration when read, such as Qiu Xing and the tallest building in Baidicheng. "Depression and frustration" is indeed the greatest feature of Du Fu's poetry style.
