Why is Du Fu called the poet of the future?

Why does Zhu Ziqing think Du Fu is a poet who links the past with the future? First of all, we must understand the significance of carrying forward the future to the future.

There is a saying in Baidu that the great cause of opening up the world by carrying forward the past and opening up the future comes from Zhuzi Quanshu, Daotong and Zhouzishu. Vernacular writing is the way to inherit the previous career and open up the future.

Besides, Du Fu, Du Fu and Li Bai are all great poets in the Tang Dynasty, but Li Bai belongs to the kind of "immortal" who doesn't eat human fireworks. Most of his poems are his own feelings, living in his own world, not listening to things outside the window, and describing things that are romantic. Du Fu's poems are quite grounded. At that time, Yuefu poetry was popular, and Du Fu did not enter the box.

Du Fu's poems have the spirit of Yuefu poems in Tang Dynasty, but they have the soul to describe real life. Their style was more vigorous and unique in the Tang Dynasty, so Zhu Ziqing thought Du Fu was a poet who connected the past with the future.
