The difference between duality and duality

Duality: Different fields have different interpretations. Literally, it is a rhetorical method. Two sentences with the same number of words and similar structure express related or opposite meanings.

Duel: The strict duality in poetry is called duel. The antithesis mainly includes the antithesis of words and sentences.

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.
