Rhyme means that adjacent words and phrases in a poem or song have similar or identical ending sounds phonologically. To determine whether it rhymes, you need to pay attention to the following aspects:
The phonological characteristics of finals: finals are one of the key factors in determining rhyme. In Chinese, finals are divided into flat rhymes, oblique rhymes and rhymes. Flat rhyme includes a, e, o, etc., oblique rhyme includes i, u, ü, etc., and rhyme includes -ng, -n, -m, etc. If two words have the same or similar vowels, they may rhyme.
The way syllables are combined: In addition to finals, the way syllables are combined also affects rhyme. Generally speaking, if the final syllables of two words have the same or similar rhyme or tone, they are likely to rhyme. For example, the "kai" and "lai" in "花开" and "风来" have the same vowels and tones, so they rhyme.
When judging whether it rhymes, you can judge whether the phonology of two words is similar through reading aloud or auditory perception. In addition, you can also refer to reference books such as rhyme books or rhyme codes, which record the phonological patterns and rhyming rules of Chinese characters.
