In It's Hard to Walk, how does Li Bai express his inner feelings by symbolic means?
Symbolism means that the poet's thoughts and feelings are not directly expressed, but implied by the description of something. In poetry, the use of symbolism not only enhances the connotation of poetry, but also makes poetry more appealing and intriguing, and improves the aesthetic effect of poetry. For example, "I want to cross the Yellow River, but the ice blocked the ferry, and it will snow in Taihang Mountain." Words such as "Frozen Sichuan" and "Snow Mountain" in the poem symbolize that one's career is difficult and blocked, which indicates that the ideal is difficult to realize. "It's hard to walk, it's hard to walk, a lot of roads, is it safe now?" The rugged road of life symbolizes the dangers of a poet's career. This not only visualizes the difficulties and obstacles of official career, but also improves the effect of expressing feelings, expands the aesthetic artistic conception of poetry and gives readers aesthetic imagination.
