In the 14th year of Tianbao (755), the Anshi Rebellion broke out, Tongguan fell, and Du Fu moved to many places. In the second year of Gan Yuan (759), Du Fu abandoned his official position and went to Sichuan. Although he fled the war and lived a relatively stable life, he still cared about the whole life and the affairs of the country.
In the winter of the fifth year of Dali (770), Du Fu died at the age of 59.

Du Fu studied poetry at the age of 7 and became famous at the age of 15. After the age of 20, there are four periods. During the roaming period, from the 19th year of Xuanzong Kaiyuan (73 1) to the 4th year of Tianbao (745), Du Fu lived a romantic life. He has roamed wuyue, Qi and Zhao successively.
In the meantime, I failed to go to Luoyang to take the Jinshi exam. Tianbao and Li Bai have been friends in Luoyang for three years. We broke up the next autumn and never met again. There are more than 20 poems of Du Fu in this period, most of which are five laws and five ancient poems, represented by Wang Yue.
During the five to fourteen years in Tianbao, Chang 'an, Du Fu was trapped in Chang 'an and was down and out. He keeps buttering up powerful people to get promoted. I have been trying to "move" for six years; In ten years, he presented three articles of "Da Li Fu", which Xuanzong appreciated and ordered the Prime Minister to try; But nothing came of it. ?
It was not until October of the fourteenth year, one month before the Anshi Rebellion, that You Weicai led Cao to join the army.
Frustration in official career and personal hunger and cold made him objectively realize the corruption of the rulers and the sufferings of the people, and made him gradually become a poet who cares about the country and the people.
The creation has undergone profound and great changes. Immortal masterpieces such as Military Vehicle Shop, Liangwei Road, Qiandi, Houdi, from Beijing to Fengxian, and famous cautionary sentences such as "The wine and meat in Zhumen stink, and the road freezes to death" have emerged.
There are about 100 poems handed down in this period, most of which are ancient poems with five words and seven sentences. From Su Zong's exile to Deyuanzai (756) and then to Gan Yuan (759), the Anshi Rebellion was the most prosperous. Du Fu also experienced hardships, but his creative achievements were enormous.
