Among them, only the metrical poems in Tang and Song Dynasties pay more attention to metrical poems, but they are not particularly strict. It was only in the Ming and Qing Dynasties that later generations overcorrected and demanded stricter rules, which often hurt the meaning of the law.
When modern people write ancient poems, it is suggested to follow the basic requirements of rhyming poems, and they can write according to the requirements of Pingshui rhyme or Chinese new rhyme, but it should be noted that new and old rhymes cannot be mixed in a poem.
Some people who are extremely retro insist on writing with flat rhymes and traditional Chinese characters, even from right to left and from top to bottom.
This situation needs no attention.
