In the same sentence, levels and levels alternate: the first, third, fifth and seventh sentences of metrical poems are called antitheses, and the second, fourth, sixth and eighth sentences are called antitheses. In the confrontation, the level balance is the opposite of the previous sentence. This rule of leveling is particularly obvious in metrical poems. If you write five words, the level is as follows: mediocre, mediocre, mediocre, mediocre. Plain, plain, plain, plain.
These flat poems are only eight sentences. Those who learn to write old poems must read them well first. Memory tricks: First, these eight sentences are actually two groups. The first four sentences form a group; Repeat the last four sentences only once, just remember the four sentences. Second, if each group begins with the word "ping", the fourth sentence must also end with the word "ping". This is what people often call "leveling" and "leveling".
