What does neat contrasting in poetry and couplets mean?

Antithesis, also called antithesis, is the most intuitive form of beauty in poetry. It is a visual art that, together with the auditory art (rhyme, rhyme), constitutes the complete metrical beauty of poetry. The quatrains do not need to be in opposition. The eight lines of the rhymed poem are divided into four couplets: the first couplet, the jaw couplet, the neck couplet and the tail couplet. The middle two couplets must use confrontation. Except for the first and last couplets, all long rhymes must be opposed.

The rules of antithesis are:

⑴ Sentences and couplets must be in opposition to each other;

⑵ The words of a sentence and the words of a couplet cannot be repeated; (In fact, no repeated words are allowed in every rhyme or poem)

⑶ The grammatical structure should be the same: that is, the sentence pattern and phrases should be the same. For example, the subject, predicate, verb and object, conjunction, partial and empty words must be the same;

⑷ The same part of speech: noun to noun, verb to verb, adjective to adjective, adverb to adverb, especially numbers to numbers. , direction versus direction, proper name versus proper name, overlapping characters versus overlapping characters, etc.;

⑸ Avoid "putting your palms together". This means that the meaning of the upper and lower lines cannot be repeated. For example: "The lotuses in summer are beautiful with thousands of branches, and the lotus flowers are blooming with thousands of flowers." This is committing the disadvantage of "putting your hands together". Huang Yi from Hunan has a pair of battle songs: "The two couplets in the middle of the verse, the upper and lower sentences are in opposition, the tones should be opposite, and the sentence patterns and parts of speech should be the same. One couplet should not have the same meaning, and the two couplets should not be too similar. The beginning and end can be right or wrong, Quatrains are generally not in conflict.
