Couplets and poems, how about learning couplets and writing poems?

Couplets are far easier to write than poems. Therefore, children in ancient times took "antithesis class" before learning to write poems, which is the way to learn antithesis first. However, the prosodic requirements of couplets are not as strict as poems. Poetry is not enough words, just a little literary talent. Rhyme has its own rules and strict requirements, while lyrics and songs are more strict. Each epigraph has its own rules and regulations: the rules of rhyming and leveling. So the ancients said "lyric poetry". Nowadays, most of the Tang and Song Ci poems are catchy and seem to be easy to imitate, but if we study their metrical patterns carefully, we can find that some decent words are not easy to fill in. But after learning couplets, it should be no problem to make metrical poems. The premise is to read more books.
