These three concepts all involve the relationship between scenery and emotion, and their differences are as follows: lyric with scenery is a lyric way, and poetry expresses thoughts and feelings by describing scenery; Writing scenery is the basic requirement and method of poetry, that is, poetry should not only describe the scenery objectively, but also integrate the poet's thoughts and feelings into it; Scenery blending is the artistic effect achieved by poetry in dealing with the relationship between scenery and emotion, and it is the way that poetry uses emotion in scenery when writing scenery (or expressing thoughts and feelings with the help of scenery description), so that emotion and scenery can be organically integrated to achieve a seamless artistic realm.
