Looking at Lushan Waterfall is a landscape poem written by the poet Li Bai when he was about fifty years old and lived in seclusion in Lushan. This poem vividly depicts the magnificent scenery of Lushan Waterfall and reflects the poet's infinite love for the great rivers and mountains of the motherland. This poem is very successful in metaphor, exaggeration and imagination, with unique conception, vivid language and bright washing. Su Dongpo appreciates this poem very much, saying that "the emperor sent the Milky Way to fall into the pulse, and there were fallen immortals in ancient times." The "immortal" is Li Bai.
