How to understand the leap of poetry?

Poetry is an art form. The so-called art originates from life and is higher than life, so poetry embodies life and is an extension of life. This requires that poetry should conform to reality, but not only to reality, but also to the relationship between reality and ideal, reality and dream. Moreover, poetry is different from novels and essays, which requires refined language and often expresses the poet's thoughts and feelings in a few sentences. This is the characteristic of poetry, which determines the leap of poetry, such as Rain in Rain by Liu Yong.
