Second, the second couplet and the third couplet of metrical poems need to be opposed, not only in meaning, structure and pronunciation. Your couplets and necklaces are not antagonistic.
As for the level tone, hehe, this is more difficult to talk about. There are generally four types of flat tones in the Five Laws, and the flat tones of each word have very strict requirements. However, if it is a good sentence, it can be modified appropriately. But if there are too many levels or tones in a sentence, it needs to be remedied, which is even more troublesome. But it is more troublesome to write ancient poems on the level tone. Ha ha!
By the way, five laws and one * * * are forty words. Generally speaking, it is best not to have heavy words, otherwise it will give people the feeling of low level.
Poetry expresses ambition, at least this is good. Nowadays, fewer and fewer people like poetry, and fewer and fewer people write poetry. I wish you could write it. If you really like it, reading more poems, not only the content, but also the structure and format, will be improved.
