What does "duality" mean?

1 Duality is a rhetorical way to express two opposite or similar meanings with a pair of phrases or sentences with the same number of words, the same structural form and symmetrical meaning. Of course, both sides should be symmetrical, and the number of words should not be too much or too little.

When using duality, first, we should pay attention to the unity of content and form, and avoid one-sided pursuit of formal symmetry and arbitrary patchwork. Second, we should pay attention to the logical relationship between the preceding and following sentences to avoid top-heaviness, mutual tolerance or overlapping concepts.

3 For example:

Water Ming Che, Mountain Kong Yu Strange (exactly the same-similar in meaning, bring out the best in each other) Su Shi's Drinking Rain after Seeing the Lake at First sight.

Full loss, little gain. (Objection-opposite meaning, reflecting each other. "Shangshu Dayu Mo")

Wildfire can't burn it out, but the spring breeze can revive it. (string pair-the same meaning, indicating coherence, progression, causality and other relations. (Bai Juyi's Farewell to Ancient Grass)

One: Classification

Duality can be roughly divided into three types:

1. Right: Two angles and two sides of things explain the same thing, which are complementary in content. The dual meaning of the previous sentence and the next sentence is similar, similar, complementary or contrasting.

2. Objection: The antithesis is called objection.

3. Double pair: also called even pair and running pair. There is a relationship of coherence, cause and effect, condition and turning point in the meaning of the first and second sentences. This kind of antithesis sentence is called a string pair.

Second: form

Duality can be divided into two forms.

1. Strict duality: the upper and lower sentences are required to have the same number of words, the same structure, relative parts of speech, and parallel, and words cannot be used repeatedly.

2. Generalized duality: As long as some of the five requirements of strict duality are met, it is not so strict.

3. There are two linguistic units in the dual, with the same number of words.
