Rhyme refers to rhyming words at the end of rhymes (poems, words, songs, fu, etc.). ). The last word of some (or all) sentences in a (first) poem is called rhyme, which uses words with the same rhyme abdomen and rhyme ending. Because rhyming words are usually placed at the end of sentences, they are called "rhyming feet". The vowels of these words should be similar or the same. Rhyme is also called vowel. Vowels are divided into three parts: the beginning, the belly and the end. Generally speaking, as long as the rhyme ending is the same and the rhyme belly is the same or similar, the rhyme head is not considered. The rhyme in metrical poems is different from that in modern Mandarin and Xinhua Dictionary. Some words have the same pronunciation and vowels, but they don't belong to the same rhyme. And some words look different in pronunciation, but you look them up in Phonology and Rhyme, but they belong to the same rhyme department.
Therefore, to write metrical poems, we must first master some simple phonological knowledge. It may be easier for southerners to learn to write metrical poems than northerners, because there are still some ancient sounds in some dialects in Wu, Fujian and Guangdong today, and many of these ancient sounds belong to the same rhyme department in The Compendium of Rhyme.
