In poetry appreciation, what is the combination of point and surface?

Analyze the whole poem through a sentence or a couplet. Generally, poets express their feelings in the neck couplet and the tail couplet, so most of them combine the description of the scenery with a word in the first couplet or the platoon couplet to analyze the feelings of the neck couplet and the tail couplet, such as expressing their feelings through the scenery. This is divided by the concreteness of different types of poems. In the topic of poetry appreciation, we must be careful not to mention only a certain point. Even if you can't feel the feelings of the author the topic wants you to write, you should make up something, and pay attention to the combination of points and aspects, that is, write small aspects first, and then write big aspects.
