Rhyme generally requires even sentences to rhyme, and couplets and necklaces should be antithetical.
First, the roaming period of reading (before the age of 30)
Du Gongbu said like [1] that "Zhao Qi is dissolute and Qiu Ma is wild".
In the 19th year of Kaiyuan (at the age of 20), he began to roam in wuyue, returned to Luoyang five years later, and then Du Fu roamed Qi and Zhao. Later, I met Li Bai in Luoyang, and the two met and hated each other late, forming a profound friendship. Then I met Gao Shi, and the three of them traveled with Liang and Song (now Kaifeng and Shangqiu). Later, Du Li went to qi zhou. After breaking up, they met on East Road respectively. This is the last time that "Shi Xian" and "Shi Sheng" met. The representative works of this period include Wang Yue, Cao Huma's poems and Li Bai.
Third, the formal period (44 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 and Love for the Head of the River. Later, he fled to Fengxiang to cheat and made a collection. Because of this suggestion, Prime Minister Fang Yi was demoted to join the army. (Fang Yi is a typical intellectual, but unrealistic. He fought against the rebels and adopted the Spring and Autumn Array, which resulted in a crushing defeat. Du Fu began to collect the left remains and wrote that Fang Fang was innocent. Su Zong was angry and wanted to find fault. Later, he recorded his experiences in the form of poems and became his immortal works, namely "Three Officials" and "Three Farewells".
