What influence did the Anshi Rebellion have on Li Bai and Du Fu's poetry creation?

Li Bai's poetic style is full of romanticism and is the representative of the prosperous Tang Dynasty. Du Fu was deeply influenced. He was worried about the country and the people, and the Anshi Rebellion laid the groundwork for his later poems. In the eyes of later generations, Du Fu's poems are more representative, that is, worrying about the country and the people, and his depressed and frustrated style is also closely related to this.
