The rhyme position (rhyme foot) of modern poetry is fixed, and 2468 sentences and 24 quatrains must rhyme (whether the quatrains rhyme or not); The ending must rhyme, generally flat (rhyming poems are too few, omitted). This is the basic rhyme.
The rhyme of modern poetry is very strict. Except for the first sentence, adjacent rhymes are generally not allowed, and even narrow rhymes with few words cannot rhyme.
If contemporary people want to use new rhymes, they can input them in Putonghua. It's best not to read some new rhyme books that put "emotion and likeness" together.
