Du Fu wrote more than 1400 poems. It profoundly reflects the social panorama of more than 20 years before and after the Anshi Rebellion in Tang Dynasty, and vividly records Du Fu's life experience. Closely combine social reality with personal life to realize the perfect unity of ideological content and artistic form; Represents the highest achievement of Tang poetry. It is called "the history of poetry" by later generations. However, Du Fu did not narrate objectively, but wrote history with poems. It reflects the reality profoundly and widely, and expresses its subjective feelings through unique artistic means. Just as Pu Qilong said: "Poems of Shaoling are a person's temperament, and things of the Three Dynasties must be sent to others" (reading). Since the late Tianbao period, Du Fu has created a large number of poems on current affairs. Short stories such as Washing Horses, Love, Being the Tao, Three Jueju, Sick Orange, Autumn Wind Breaking the Cottage, Appearing as Wu Lang, etc., while novels such as Shuhuai in Kuizhou, Wangzai, Cottage and Mourning have different contents. There are a lot of war themes in Du Fu's poems. Du Fu has different attitudes towards different kinds of wars. Those who oppose the imperial court's belligerence and consume national strength are "Garage Shop" and "Going to the Foot of the Backyard". Two poems, Watching An Xi Soldiers Go to Guanzhong and Stand by, Watching Soldiers and The Year of National subjugation, supported the suppression of rebellion and resistance to foreign aggression. Two groups of poems, Before the Frontier and After the Frontier, not only praised the bravery of the soldiers, but also condemned the insatiable frontier expansion of the king and the arrogance and extravagance of the lords. The confession of a soldier sums up the unfortunate fate of countless brave soldiers. In "Three Officials" and "Three Farewells", the poet sympathizes with the people's sufferings and hates barbaric Latin; However, due to the current situation of the enemy and the shortage of troops, he can only comfort the conscripts with tears. It shows the sharp and complicated contradictions and conflicts in the author's heart. Du Fu has many poems praising nature. The object of singing is often related to oneself and current events, and it is a blend of feelings, scenes and events, not just scenes. The most representative ones are Spring Hope and Sword Gate.

Du Fu also has some poems praising painting, music, architecture, dance, utensils and agricultural production, which also focus on the author's feelings and have the characteristics of the times. There are also some poems in Du Ji, which are not strong in the flavor of the times and indifferent in personal feelings, especially some poems written in Chengdu Caotang.

It embodies the other side of Du Fu's poetry and life. Du Fu's poems about missing relatives and friends are mostly sentimental and spoony. For example, I miss his wife on a moonlit night, and my brother misses his younger brother on a moonlit night. Among many poems and songs about cherishing friends, the most outstanding one is to commemorate Li Bai. From breaking up with Li Bai to his later years, there were 15 poems that remembered or talked about Li Bai. Showed his admiration and friendship for Li Bai. Du Fu also commented on poetry, and expressed his artistic thoughts of "benefiting from many teachers" and "tailoring for the body" in "Play is six quatrains", "Occasionally Topic" and "Twelve Poems for Relieving boredom" (the fourth to the eighth), abandoning the past and the present and casting macro words. During his stay in Chang 'an and wandering southwest, Du Fu also wrote some poems with boring content and low style, which were dedicated to dignitaries, officials and social parties.

Seven-character ancient poems are good at stating opinions, with bold and gloomy feelings and strange style; Such as Drunk Songs for Zheng Guangwen, Washing Horses, Autumn Wind Breaking the Cottage, Sui Yanxing, etc. Five, five-character rhythm poems and seven-character rhythm poems are extremely skilled; The five laws are the longing for spring, reaching Li Bai at the end of the day, traveling later, "Delighting in Rain on a Spring Night", water sill, going abroad overnight, climbing Yueyang Tower, and the seven laws are Shuxiang and Elymus. The two sides of the Yellow River were recaptured by the imperial army, and Su Fu, Bai Di and five generals. The rhythm of the Tang Dynasty rarely surpassed them. Du Fu also has many five-character poems and several seven-character poems, which have greatly developed the poems. His "Autumn Li Ke Bai Yun" has 1000 words.
