First of all, their origins and development directions are different. Du Fu was born in an official family with a superior family. His grandfather is knowledgeable and a famous writer in the early Tang Dynasty. Du Fu was influenced by family art since childhood, which laid a solid foundation for his fame in the literary world. When Xin Qiji was born, he was in a rather chaotic historical period. At that time, the north had been defeated by the state of Jin. Xin Qiji suffered the humiliation and pain of the Jin people's rule, and his hatred with the Jin people was too deep, which made him set his ambition to become a knight-errant when he was young.
If we elaborate on Du Fu, his adult life is not smooth sailing, full of ups and downs. He experienced the whole historical period from the prosperous Tang Dynasty to the decline, and until the early Song Dynasty, Du Fu's works were popular. He is especially good at the creation of rhythmic poems, which are usually divided into seven-character rhythmic poems and five-character rhythmic poems. Poetry is regular in sentence rhyme and word image. It was he who brought this poetic style to a new peak and played an irreplaceable role in the development of Tang and Song poetry.
In addition, Xin Qiji and Du Fu are completely different in the style of their works. Xin Qiji is good at lyrics, and Du Fu is a poet. During the Tang and Song Dynasties, the popularity of poetry was slightly higher than that of lyrics. Xin Qiji's works mostly reflected patriotism and described the conflict between ideal and reality. The boldness of Du Fu's poems lies in their ability to reflect reality and strong realism. Through Du Fu's works, we can see the historical track of China from Tang Dynasty to Song Dynasty.
In the eyes of later generations, Du Fu's poems can better reflect the charm of human nature and are closer to the life of modern people, which is the standard poetic style for learning poetry. Therefore, Du Fu has more literati in mobike than Xin Qiji.
