1, before and after care
Reference refers to the foreshadowing reference between poems, also called echo, which is a common structural form of classical poetry. A poem, whether it is a verse or a quatrain, should have a beginning and an end, and the contents before and after must be internally related. If it is explained in front, it must be managed later; If you want to take care of the back, you must have a confession in front to form an organic whole. In this way, the whole poem can run through, the plot is coherent, the context is clear and the structure is compact, which makes it easy for readers to grasp the context of the whole poem.
The coordination between the beginning and the end, that is, the coordination between the beginning and the end, makes the poem feel integrated in structure, highlights the theme and plays a good expression effect. In some poems, poets often express their feelings or those of others by taking care of the past and the present, others and me, and things and me.
