However, due to its self-harmony, it has evolved into a rhyme or a blank rhyme for completeness and rhythm. Of course, there are also differences between flat and even rhymes. So the first sentence of the quatrains doesn't rhyme at all, but it rhymes later. The quatrains must be neat, because the couplets and necklaces in the rhyme must be neat.
Jueju originated in Han Dynasty, formed in Wei, Jin, Southern and Northern Dynasties, and flourished in Tang Dynasty. At that time, there were four sentences called "couplets". The so-called "Wen Xin Diao Long Shi Ming" has a rhyme of * *, which makes it redundant. The Tang and Song Dynasties were the golden age of China's classical poetry. Quatrains are popular all over the world, and their creation is prosperous. The famous Zhang Jiashi is as beautiful as a group of flowers, and its grand occasion is unprecedented.
Quatrains can be divided into metrical quatrains and archaic quatrains according to poetic rhythm. According to the number of words in each sentence, quatrains can be divided into five-character quatrains, six-character quatrains and seven-character quatrains, of which five or seven quatrains are the majority and six quatrains are few.
Quatrains appeared only after the rise of metrical poems, while ancient quatrains existed long before the appearance of metrical poems. Xu Ling, editor-in-chief of Chen Dynasty in the Southern Dynasties, is known as the "ancient quatrains". However, although this quatrain rhymes, it is relatively free, or it can be said that some poets are unwilling to be bound by meter. After the popularization of law, ancient quatrains are still in use and development. There were many five-character quatrains in ancient times, but few seven-character quatrains. So seven words and eight sentences are not very common.
