Du Fu's poems fully expressed his deep sympathy for the people and exposed the sharp opposition between the exploiters and the exploited in feudal society. Du Fu bravely, faithfully and profoundly reflected the extremely extensive social reality with the spirit of actively joining the WTO. No matter what kind of sinister situation, he will not lose heart. In the long history of China literature, the cognitive function, reference function, educational function and aesthetic function of Du Fu's poems are unattainable.
The greatest artistic feature of Du Fu's poems is that poets often hide their subjective feelings in objective descriptions and let things impress readers themselves.
