[Introduction]
Any poem requires rhyme, no matter ancient or modern, Chinese or foreign. The difference is that there are more or less restrictions on rhyme, and there are strict and wide restrictions. This is also the biggest difference between poetry and other literary genres.
Rhyme is an important means to enhance the musicality of poetry. Modern poetry pays great attention to rhyme in order to make the tone harmonious and easy to remember. The ancients usually used official books that specially instructed the use of rhyme, such as Tang Yun, Guang Yun, Libu Rhyme, Peiwenyun, Poetic Rhyme Integration and Poetic Rhyme Combination. Among them, Wang Wenyu's New Publication Rhyme in the Southern Song Dynasty is the most popular, and it is called "Pingshui Rhyme" by the world.
But what needs to be understood is that it is not worth destroying the essence of poetry in order to accommodate rhyme. Unless you take part in the imperial examination, even if a sentence or two rhymes occasionally, the ancients are allowed.
