How did the ancients demand the fluency and rhythm of poetry? Can you give me a detailed answer?

Hello, let's talk about rhythm first. First of all, rhyme is the most basic. We need different methods according to different situations. Most of the sentences we see rhyme with even numbers. Before the Tang and Song Dynasties, the first sentence often rhymed, and then the consecutive sentences rhymed. Of course, for example, the uniqueness of Bailiang style is that each sentence rhymes and is limited to seven words. Rhyme means that the last word of related sentences has the same vowel. Specific rhymes and other knowledge can be found in related books.

Flat tones, because many ancient sounds are different from today's sounds, so the modern summary of flat tones of ancient sounds conforms to modern sounds. One level, two levels, three or four levels. This is compared with the ancient sound. You can also get familiar with it. Most of the flat words we talk about generally refer to the arrangement of words in poetry. In order to make poems more aesthetic, such as "plain, plain", some poems say "135 regardless, 246 strict", in fact, for the aesthetic feeling of poems, it is more comfortable to read.

Finally, the requirement is that the second half of the five-word sentence should be clear. The even numbers of sentences in seven words should be clear. There are no special circumstances, even the sentences must rhyme. In most cases, rhyme is the author's choice.

That's about it. Only personal, not professional. I hope you can read more books.
