Duality is a metaphor. Are two sentences used in pairs, with the same number of words, the same structure and part of speech, and related meanings. This symmetrical way of language has formed a neat and harmonious expression and set off each other in content, which has a unique artistic effect.
Duality refers to a special form of expression and means used in poetry creation and couplet writing. It requires that poetry conjunctions be based on duality, and that words with the same structural position in the upper and lower sentences must be "of the same part of speech and flat", so as to avoid the repeated use of words with the same structural position in the upper and lower sentences.
The antithesis of metrical poems makes the language sound and rhyme harmonious, enhances the sense of rhythm and musical beauty, and achieves a high degree of perfection in expression. Therefore, metrical poetry is very strict with antithesis, and the couplet that conforms to the above principles is antithesis; Otherwise, you don't play or you can't play steadily.
Petals fall like tears, and lonely birds sing their sadness.
Extended data:
Dueling is often used in parallel prose. Dueling is also called duality, team warfare and parity. It puts words with similar or opposite concepts in corresponding positions, so that they set off each other, make sentences more attractive and increase the expressive force of words. Confrontation is like a ceremonial ceremony of the government, opposing each other. Duantithesis is closely related to the parallel connection in the Han and Wei dynasties, which can be said to be developed from parallel connection, and Duantithesis itself should also be a parallel connection.
The specific contents of the antithesis of metrical poems are as follows: first, the upper and lower sentences must be opposed; Secondly, the sentence patterns of relational sentences should be the same, and the syntactic structures should be consistent, such as subject-predicate structure versus subject-predicate structure, partial structure versus partial structure, and predicate-complement structure versus predicate-complement structure. The sentence structure of some antithetical sentences is not necessarily the same, but the words are required to be relative.
Thirdly, the parts of speech (parts of speech) of words are required to be consistent, such as noun to noun, verb to verb, adjective to adjective, etc. The lexical meaning of words should be the same. As nouns, words that belong to the same meaning range, such as astronomy, geography, palace, clothing, utensils, animals, plants, human body, behavior and action, can all be correct.
The use of duality is wide and strict, so there are many types, including working pair, adjacent pair, wide pair, borrowing pair, running pair and sector equivalence. In terms of content, there are names such as right, right, right and opposition.
The requirement of word antithesis is that the meaning of words must belong to the same category, such as mountains and rivers to mountains and rivers, vegetation to vegetation and so on. ; Parts of speech must be basically the same, such as noun to noun, verb to verb, etc. Leveling must be relative, that is, leveling or leveling; The structure must be symmetrical, that is, simple words to simple words and compound words to compound words; In addition, we should avoid antonyms of the same word.
The antithesis of sentence patterns is mainly the same sentence structure, such as subject-predicate phrase to subject-predicate phrase and verb-object phrase to verb-object phrase.
Contradiction can make poetry appear neat and symmetrical in form and meaning, giving people a sense of beauty, which is a unique artistic means of Chinese.
