1, "poetry expresses ambition" means that the poems in The Book of Songs all express the author's feelings and thoughts, and every sentence in the poem contains the author's feelings and thoughts, which can be feelings and thoughts about love, friendship, family, country, society and other things. Therefore, The Book of Songs is known as "the book of poets' souls".
2. "Out of context" means that some people only quote part of the Book of Songs without understanding the background and significance of the whole poem. This practice can easily lead to misunderstanding and misinterpretation of poetry, so we need to fully understand the content and significance of the whole poem when quoting the Book of Songs to avoid misunderstanding and misinterpretation. The Book of Songs is one of the representative works of ancient Chinese poetry, and "poetry expresses ambition" and "out of context" are its unique expressions.
