Mr. Guo Moruo's couplet "The devastation in the world is reflected in the sages in the poems; the sufferings of the people are reflected in the writings" was written by the poet Du Fu.

Du Fu created such masterpieces as "Spring Look", "Northern Expedition", "Three Officials", and "Three Farewells". In 759, Du Fu abandoned his official position and went to Sichuan. He escaped the war and lived a relatively stable life, but he still cared about the people and national affairs. Although Du Fu was a realist poet, he also had a wild and unruly side. It is not difficult to see Du Fu's heroic spirit from his famous work "Song of the Eight Immortals in Drinking".

The core of Du Fu's thoughts is the Confucian benevolent thought. He has the grand ambition of "making kings Yao and Shun the emperor, and then making customs pure." Although Du Fu was not well-known when he was alive, he later became famous far and wide. Both Chinese literature and Japanese literature have had a profound influence. About 1,500 poems by Du Fu have been preserved, most of which are collected in "Du Gongbu Collection".
