1, two concepts

Duality is a metaphor. The two sentences used in pairs are "the number of words is equal, the structure and part of speech are roughly the same, and the meaning is related". 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.

2. Two language forms.

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, it is not confrontation or unstable confrontation, which is not allowed in poetry creation. ?

Duality and duality are two very similar language forms. The so-called "similarity" means that they are more similar and less different, so it is more difficult to distinguish them. Even some reference books have vague explanations of these two concepts.

3. Used in different styles.

For example, under the "antithesis" chapter of Ci Hai, the annotation says: "It refers to the duality of poetry and words." China Self-study Dictionary of Ancient Literature by Shaanxi Education Publishing House interprets "duality" as "a rhetorical method, which is called duality in poetry."

This explanation of "duality" with "antithesis" and "antithesis" with "antithesis" leads to the confusion of concepts, and as a result, people mistakenly think that "duality" and "antithesis" are the same thing and two titles of the same concept.

To sum up, duality is used in prose and poetry, and duality is only used in metrical poems or couplets. Dual upper and lower sentences can have the same word, and antithetical couplets cannot have the same word. Dual sentences don't pay attention to hierarchy and relativity, but couplets must be hierarchical and relative.

Extended data:

Similarities between antithesis and antithesis: By comparison, the similarity between the two is that there is a word "antithesis", which means that the two sentences should be relative, the overall structure should be the same, and the meaning should be related (that is, there is a certain connection). Its aesthetic function is to make the phonology of language more harmonious, enhance the sense of rhythm and beauty of music, and improve the expression effect.

Because different styles have different requirements for their own expression, they also have different requirements for expression forms. As the antithesis of rhetorical methods, it is often widely used in various styles, especially in ancient Chinese prose and poems. It promotes the language, and the two even sentences complement each other and set off each other, making the language beautiful in form and expressive.

Contradiction is a unique creative technique in metrical poetry. The metrical poems, which rose in Sui and Tang Dynasties, strictly require that couplets and necklaces in metrical poems must be opposed. At the same time, this method is also adopted by song creation. Later it was used to write couplets.

Because the creation of rhymes and songs itself has high artistic requirements for the use of language, it pays attention to the choice of words and sentences, and confrontation can greatly improve the expression skills and aesthetic taste of poetry to a certain extent, with high artistry and expressiveness. These special functions of duality are obviously beyond the reach of duality.

It can be said that "antithesis" is one of the important criteria for the creation and appreciation of metrical poetry, and naturally it has become a term exclusively for poetry. Because of this, although antithesis in metrical poems also meets the standard requirements of antithesis, in view of its own characteristics and in order to distinguish it from antithesis in general style, we usually call it antithesis instead of antithesis.
