Who can tell me what are the main artistic features of Li Bai and Du Fu's poetry creation? I'm sorry

Li Bai's poems inherited the romantic tradition since The Songs of the South and formed its own unique style: passionate feelings, magnificent momentum, rich imagination, fresh language and romantic colors.

Du Fu's poems are characterized by rigorous meter, restrained emotion, depression and frustration, full of realistic artistic style, and his personality characteristics of worrying about the country and the people.
