Smart use of symmetrical sentences:

The so-called symmetrical sentences are sentences that appear in pairs, but the number of words does not require completely equal or symmetrical sentences, and does not require completely neat sentences.

In argumentative essays, symmetrical sentences can be used both to reason and to give examples. Because it requires the use of large and neat sentence patterns and symmetrical structures to prove arguments. Conscious use of symmetrical sentences can not only improve the ability to refine language, but also because the use of arguments is extremely concise, it can also exercise the ability to highly summarize examples.

If it is said that "stones and jade make mountains shine, and water holds pearls and rivers are beautiful," then the application of symmetrical sentences will also make the article shine.
