The pronunciation of modern Chinese is different from that of ancient times, some of which rhymed with the ancients, but now it seems that there is no rhyme. There is a great difference between the present Mandarin and the ancient Mandarin. One of the biggest differences is the lack of a tone. There are only four tones in Mandarin, while there are five tones in ancient Mandarin. Wu dialect is five tones. In fact, most dialects in China have maintained five-tone pronunciation, and Minnan dialect and Cantonese even have more than six tones. (If you look at it in Minnan dialect and Cantonese, it doesn't rhyme in our eyes. Maybe the dialect rhymes! )
Moreover, at the beginning of poetry, such as The Book of Songs and Yuefu, classical poetry is not yet mature, and the requirements for rhyme and levelness are not high, so some really don't rhyme!
Generally, ancient poems don't rhyme. Li Bai's 59 ancient poems rhyme, change rhyme in the middle and have no rhyme. 5 ancient 7 ancient, quatrains must rhyme. Poetry is like this, so are the lyrics, but the rhyme of the lyrics is different from that of poetry, and some of them are separated by sentences.
Ancient poems that don't rhyme: there are tall buildings in the northwest, guests from afar, watching the sea-Cao Cao, Cao Zhi on Mount Tai, Zhang Meng Haoran on Mount Denglan in Qiu Lai.
The above are only personal views, unofficial views. For reference only! )
Not every capital letter rhymes, but some ancient poems don't rhyme, because the development is still immature.
What you said-
Hu Ling Langzhong
You are the cloud of Songshan, and I am Qin Chuanshu, who has been away from home for a long time; Thousands of miles away, you sent a letter of sympathy.
Please don't ask me about the joys and sorrows of Lao Liangyuan; I am like a disease in the autumn rain, Sima Xiangru.
Rhyme, four lines, not only rhymes, but also is an even number! It's a four-line format. Look up the ancient rhyme table, house and book, for example, it rhymes, but it seems that modern people don't rhyme because Chinese pronunciation has changed! )
On the voice of six fish: (Lift, Shu, such as. It's homophony)
At the beginning of fish fishing, Shu lived in the canal, Yu Yu was famous, Seo Woo was hoeing and thinning vegetables, and Xu Shu was in Shu, raising pigs and donkeys, and so on.
