Bai's poems are bold and bold, while Du's poems are melancholy.
Also when climbing high, Li Bai's view of the scenery in front of him is that he opens up to the sky and the earth, while Du Fu, on the contrary, draws in himself from the distant view.
Li Bai: Climbing high is a spectacular sight between heaven and earth. The vast river never returns, the yellow clouds are moving thousands of miles away, and the white waves are flowing over the snow-capped mountains.
Du Fu: The endless falling trees are rustling, and the endless Yangtze River is rolling in. Wandering With Melancholy, a century on stage alone and sick.
