The styles of Du Fu's poems are diverse, and the reasons for their diversity are also diverse and complicated. The changes of the times, the ups and downs of life, the great fusion of ideas, the diversification of poetic style, the law of literary development and Du Fu's literary view are all reasons for the diversification of Du Fu's poems.
The Tang Dynasty, especially in its heyday, was an all-inclusive era. Literature under this economic and social condition must not be a stagnant pool, which determines from the source that Du Fu's poems are not single and flat, but must be three-dimensional and full.
The integration of Confucianism, Buddhism and Taoism and the diversification of social thoughts also conform to the diversification of Du Fu's poetic style. Of course, the sudden change of the poet's own personality, personal experience and social politics will affect and change his poetic style, making his poems show unique characteristics, which has created the mainstream of Du Fu's poetry and is not contradictory to his diversified poetic style.
Du Fu is a great poet, and his poems are extensive and profound. A multi-angle and three-dimensional view of his poems not only conforms to the actual social situation, but also conforms to the poet's personality characteristics, and can also fully understand Du Fu and Du Fu's poems.
