Flat tone means that the sound should be flat between the steps of the upper and lower couplet and the feet of each clause, that is, the upper couplet is flat tone, the lower couplet is flat tone, and vice versa.
There is a requirement that no matter what 135 is, 246 is clear.
1, 3, 5, regardless of the seven words in the seven-word sentence: 1, 3, 5, three words, can be flat, 246 needs to be obviously flat.
1. In the seven-character sentence, the flat-footed sentence can have three words, and the flat-footed sentence can only have two words. For example, this sentence: even if the third word is ignored, it will become: even if it is flat. This is the crime of loneliness, and one of the biggest taboos in regular poetry is loneliness.
2. Salvation theory. Every flat tone is called a difficult sentence, and it is quite common to omit it as much as possible in metrical poems. For example, the sentence "Five words rhyme, even and even". The first word is ambiguous, and the third word is remedied, and it becomes: Pingping Pingping Pingping Pingping Pingping Pingping Pingping Pingping.

avoid
1, avoid rhyme
That is, the same rhyme word appears repeatedly in the rhyme of a poem, which is a big taboo.
2. Avoid synonyms.
For example, a poem uses "flower", "flower", "fragrance" and "fragrance" at the same time.
Step 3 avoid rhyming
Most ancient poems were written according to the official rhyme, and many words that we thought were homophones were included in different rhymes in the official rhyme, such as "winter" and "east". If you are juxtaposed in the same poem, it is rhyming. This is mainly due to the changes in ancient and modern pronunciations, which need not be emphasized today.
