There are 2468 rhymes in metrical poems and 24 rhymes in quatrains. Whether it is a metrical poem or a quatrain, the first sentence may or may not rhyme. For example:
A Letter to Han Chuo (Du Mu), the Magistrate of Yangzhou
There is water in the green hills, and the vegetation in the south of the Yangtze River is withered in autumn.
Where does the Jade Man teach oral sex at Bridge 24 on a moonlit night?
The first 124 sentence rhymes. Another example is:
Leyou Tomb (Li Shangyin)
In the evening, I was unhappy and drove to Gu.
Sunset, infinitely beautiful, only near dusk.
The first sentence doesn't rhyme, but two or four sentences rhyme. Generally speaking, it is common that the first sentence of five-character poems does not rhyme, and it is also common that the first sentence of seven-character poems rhymes. For the rules of whether the first sentence rhymes or not, please refer to Table ④ of Pingping.
Only bet on rhymes.
It is almost a dead rule that modern poetry can only rhyme. In fact, in the style of modern poetry, it will be very difficult to bet the sound, so the ancients can consciously abide by this rule. There are no counterexamples in memory, so I won't give them here.
Rhyme at the end
You can't change rhyme in the middle. Ancient poems (ancient styles) are allowed to change rhyme in the middle, but modern poems are not allowed to do so.
The rhyme of the first sentence can be borrowed from the adjacent rhyme.
The rhyme of ancient poetry can be mixed with the rhyme of adjacent rhymes, such as one east and two winters, four branches and five micro.
Being together is called rhyme. However, the rhyme of modern poetry must strictly only use homophonic words, even if
There are very few words in this rhyme (called narrow rhyme), so you can't mix words in other rhymes, otherwise it's called rhyme, which is the taboo of modern poetry. But if the first sentence rhymes, you can borrow adjacent rhymes. Because the first sentence can be put or not, you can bend the rules. For example, "Drunk to Send Ba Shen Liu Sou to the Army":
Wine is thirsty for Qingjiang River, and I prefer to wash my stomach.
Soft sand leans on the seat, and Leng Shi wakes up drunk.
Picnics are accompanied by accounts, and Huayin is happy.
Several cups are missing. They have all been sent to Shen Ming.
This song "Ting Xing Ling Ming" consists of nine tones, but the first sentence borrows the word "Qing" from Ba Geng.
This is called borrowing neighboring rhymes, which was popular in the late Tang Dynasty and even formed an atmosphere in the Song Dynasty.
I'm glad to answer your questions and hope to adopt them!
