Let's look at Dong, Tong, Long, Zong, Cong and so on. Their vowel is ong, so they are homophones, and homophones can rhyme. The so-called rhyme means putting two or more rhyming words in the same position. Generally, rhyme is always placed at the end of a sentence, so it is also called rhyme.
Try the following example:
(1) this poem is not by' plain' will catchy! What really works is rhyme!
(2) Because most of the poems (couplets) handed down by the ancients and predecessors were written according to' Pingqi', the so-called catchy' Pingqi' poems (couplets) handed down naturally accounted for a large proportion. There are relatively few people who don't follow the' level'.
Pingping will not change whether it is catchy or not!
(3) Do you think poems (couplets) written alternately with horizontal lines will be catchy? This is an unthinking illusion! Some people are the result of inertia thinking after being brainwashed by blind followers! Is misled by illusion!
If you remove the catchy ending word "rhyme" and replace it with a word without rhyme, you will feel the magical feeling that catchy words don't matter!
Summary: As long as the sentence is smooth and natural, and the rhythm points (steps and beats) of the upper and lower couplets (sentences) are consistent, no matter what kind of flat characters are used, the whole sentence will have a sense of rhythm, frustration and neatness! On this basis, rhyme will be catchy!
