Du Fu is a great realistic poet, who wrote 1400 poems in his life. His experience and poetry creation can be divided into four periods.
First, the roaming period of reading (before the age of 35)
During this period, he traveled to Wu, Yue (now Jiangsu and Zhejiang), Qi and Zhao (now northern Shandong and southern Hebei) and worked in Luoyang. After meeting Li Bai in Luoyang, they formed a profound friendship, then met Gao Shi and traveled with Liang and Song (now Kaifeng and Shangqiu). Later, Du Li went to Jizhou again, met at the east foot after breaking up, and separated again, so there was no chance to meet again.
Second, trapped in Chang' an period (35 to 44 years old)
During this period, Du Fu took the exam in Chang 'an for the first time and came last. Later, he presented gifts to the emperor and presented them to the nobles. He lived a life of "detaining the rich in the morning, following the fat horse dust at night, throwing a cup and baking it cold, hiding his worries everywhere". Finally, he got a small official who led the government to join the army. During this period, he wrote poems such as "Car Shop" and "Two Ways", criticizing current politics and satirizing dignitaries. The book "Singing 500 Words from Beijing to Fengxian" is particularly famous, which indicates that his understanding of the political and social reality of the imperial court has reached a new height after ten years of hard life in Chang 'an.
3. Being trapped as a thief and being an official (45 to 48 years old).
When the Anshi Rebellion broke out and Tongguan fell, Du Fu settled in Zhangzhou and went to Suzong alone. He was captured by the Anshi Rebellion and taken to Chang 'an. In the face of chaos in Chang 'an, he heard the news that the loyalist troops were repeatedly defeated, and wrote poems such as Moonlit Night, Spring Hope, Ai Jiangtou and Sad Chen Tao. Later, he fled to Fengxiang to cheat and made a collection. Because of the suggestion, Shangshu was demoted to be the prime minister of joining the army. Later, he recorded his experiences in the form of poems and became his immortal works, namely "Three Officials" and "Three Farewells".
Fourth, the wandering period in the southwest (48 to 58 years old).
With the collapse of Xiangzhou loyalist and the famine of Guanfu, Du Fu abandoned his official and fled with his family, passing through Qin Zhou and Tonggu, and lived a relatively stable life in Chengdu. When he entered the DPRK, the warlord in the middle of Shu rebelled and he went to Zizhou and Langzhou. Then go back to Chengdu. After Yanwu's death, he drifted again, lived in Kuizhou for two years, drifted to the same lake and died on the Xiangjiang River. The works of this period include Heart on the Water Threshold, Delighting in Rain on a Spring Night, Autumn Wind Breaking the Cottage, Sick Orange, Climbing the Building, Book Reading, The Yellow River was recaptured by the imperial army, Showing Wu Lang again, Ascending the Mountain, Qiu Xing, Three Jueju and Sui Yanxing.
Throughout his life, Du Fu's thoughts were "worrying about Li Yuan in poor years" and "being the best monarch and being Yao Shun", so his poetry creation always runs through the main line of worrying about the country and the people, which shows Du Fu's greatness. His poems are rich in social content, rich in the color of the times and distinctive in political inclination, which truly and profoundly reflect the political current affairs and broad social life prospect of a historical era before and after the An Shi Rebellion, and are called the "history of poetry" of a generation. The style of Du Fu's poems is basically "gloomy and frustrated", and the language and text structure are full of changes, emphasizing the refinement of words and sentences. At the same time, his poems have many styles. Besides the five ancient poems, the seven ancient poems, the five laws and the seven laws, he also wrote many lines. There are also various artistic techniques, which are the epitome of the ideological art of Tang poetry. Du Fu also inherited the spirit of Yuefu in Han and Wei Dynasties, got rid of the old themes of Yuefu, and created many new themes of Yuefu, such as "three officials" and "three parting", which had a positive impact on the "new Yuefu movement" of Baiyuan. For details about his life, see Old Tang Book (volume 190). This is Du Gongbu.
