A question was answered a few days ago: why are some people who do not understand the rhythm of poetry still say something positive? What is the mentality of breaking the constraints of the rhythm?
Metrics are bound without errors. Poetry is originally a dance with shackles, but some of these "shackles" are tighter and looser.
Regarding the question of the subject, we can sort it out from three aspects, namely:
Do not understand, love or not.
Once you understand what you don't use, you know that there is no such thing as a broken rhythm.

The metrical poetry originated from Qi Liang Yongming style. At that time, Shen Yue and other poets studied the application of four sounds and eight diseases in poetry creation.

Shi 嘤 -qi-juvenile, qi-moving-chuping. Once the old country was blocked, thousands of miles passed.
The poet found that in one sentence, there was more beauty in rhyme, so the rulings of peace and relative confrontation gradually matured. Even in the late Northern and Southern Dynasties, completely standard metrical poetry appeared.
The Xincheng Anle Palace, a famous poet of the Southern Dynasty, is a five-character rule:
