What is the rhyme of the poem "Request"

Wen Xin Diao Long refers to the sum of different sounds and homophony. In the Book of Jin, the tone and sound style should be based on harmony, which will double the income and halve the loss. Lu Fu collected immortal prose with a thousand-year charm.

The so-called rhyme in poetry is roughly equal to the so-called vowel in Chinese Pinyin. As we all know, when a Chinese character is spelled with pinyin letters, there are usually initials and finals. For example, the word "q iu" is spelled Qiu, where Q is the initial and iu is the final. The first letter is always in front and the vowel is always in the back. The word "l iu" is spelled as l iu, where l is the initial and iu is the final. So it's a homophone, and the rhyme is iu.

If a matching word is found, the vowel after it is iu.
