In what ways does lyric poetry express the author's thoughts and feelings?

As a kind of poetry, lyric poetry directly expresses the author's thoughts and feelings, exposes the poet's inner world and indirectly reflects social life. Lyrics do not pursue the description of characters and plots, but pay attention to the expression of personal feelings. Even though there are some descriptions of life phenomena and natural scenery in the poem, the poet still expresses his feelings and emotions by expressing his will or borrowing scenery.
