Which part of the vowel should be the same, the rhyme, the rhyme belly or the rhyme ending?

Rhyme, or rhyming, refers to the use of words with the same or similar vowels in the last word of some sentences when creating rhymes, so as to produce a sonorous sense of harmony when reading or singing. These places where the same vowel is used are called rhymes. The rhyme of modern poetry has strict rules, which can be summarized as follows: the first sentence can be bet or not, and the next sentence must be flat. Rhyme 2468, quatrains 24, the first sentence can rhyme or not. Rhyme means that vowels have the same ending.
