Difficult to Go is a poem written by Li Bai after he was excluded from Chang 'an. There are three poems, and most of us are familiar with the first one. This poem uses the metaphor of "it is difficult to go to the sky" to express the poet's uncontrollable anger when he encounters difficulties on the political road; However, he did not give up his lofty political ideal because of this, and still hoped that one day he could display his ambition, show his optimism and heroism for his future life and be full of positive romanticism.
In this poem, the poem that uses metaphor to describe the danger ahead is: I want to cross the Yellow River, but the ice-choked ferry will climb the snowy Taihang Mountain.
