Du Fu's style is a gloomy and tragic reality.
Wang Wei's style is quiet and profound, and poetry and Zen are one.
Han Yu's style is majestic.
It is said that Li Bai's poems are extraordinary, which is more a kind of pride and a release of ambition to serve the country, while Wang Wei advocates Buddhism, specializes in Zen, is proficient in temperament, and gives people more artistic care. Du Fu's poems, like saints, reflect human sufferings and pity the people, just as he said in his poems: Let the monarch be Yao and Shun, and then make the vulgar pure. Only Du Fu's poems can best show sympathy for others. Finally, let me talk about Han Yu. As a literary school, Han Changli's poems also inherited his literary style. In the words of Si Kongtu, a poetic theorist in the late Tang Dynasty, it is "moving with the momentum, soaring between heaven and earth if thunder lifts". Simply put, it is famous for its momentum. This is the biggest difference between the four poets.
