Is this a limerick?

Well, writing poetry requires strict antithesis, and people are shouting, "No matter what 135 is, 246 will be clear." The requirement is that the second, fourth and sixth words must be flat, and the sixth word of each sentence is flat, which violates the principle of "one sentence is flat, one sentence is flat". You can tell him that I'm an antique, and I don't need to give a straightforward account. I just want to express my feelings. Besides, people who write poems generally humble their works into limericks, regardless of what others say. Learn to write slowly, and there will be good works.
