The second half reflects the poet's thoughts and feelings of patriotism and love for the people after wandering in heaven, pursuing the realization of ideals and dying after failure. The whole poem uses the metaphor of beauty and vanilla, a lot of myths and legends and rich imagination, forming a gorgeous literary talent and magnificent structure, showing a positive romantic spirit, and creating a "Sao style" poetry form in the history of China literature, which has a far-reaching impact on later generations.
