A detailed comparison shows that Li Bai is good at self-lyric, most of which are lyric poems, and narrative poems are also lyric. His poems always focus on "self", emphasizing and promoting the role of the subject, and even reaching the level of controlling and conquering the object (describing the object). For example, "Shu Dao Nan". The poet has repeatedly lamented that "it is difficult to learn Shu Dao and go to heaven", which was originally intended to imply that the poet's image is everywhere.
The social content of Du Fu's poems is directly presented through real and vivid pictures of social life. So it's easy to recognize. The image of Li Bai's poems is mainly the poet himself, not the objective social life, so his social content is not easy to be understood.
