This five-line poem is difficult to write because:
The number of (1) sentences is fixed. Only four sentences, five words each, a total of * * * twenty crosses.
(2) Rhyme is strict. Poetry rhymes, some with sentences, and some with other sentences. There is no essential difference between them and classical poetry in rhyming with other sentences, and his rhyming is rigorous. Generally speaking, it can only be flat, not rhyme. That is to say, you can't rhyme, and you must use words with the same rhyme, not words with adjacent rhymes.
(3) Pay attention to leveling. On the basis of "Pingping-Zuoping, Zuoping-Pingping", a syllable is added to form "Pingping-Zuoping-Pingping, Zuoping-Pingping".
Four basic sentence patterns: Pingyi, Pingyi and Pingyi.
(4) On the dual problem. Because quatrains can be regarded as the interception of metrical poems, the requirements for antithesis are not too strict.
