2. "Birds fly high, lonely clouds go to leisure alone" shows an extremely empty and lonely world. It should mean: the birds that get along with Jingting Mountain day and night fly away, the last white cloud in the sky floats away, everything disappears without a trace, and there is silence between heaven and earth, and only the poet sits there alone. Although the two poems are written in front of us, the lines between them reveal the poet's strong sense of loneliness.
When Li Bai wrote this poem, it was nearly ten years since he left Chang 'an. At this time, Li Bai had a deep understanding of the disadvantages of the society at that time, and his arrogant personality made him unable to tolerate reality, so his loneliness became stronger and stronger, and his cynicism increased day by day. He had to seek comfort from nature and a bosom friend. This poem expresses such a mood.
