The antithesis of quatrains, rhymes and poems has its own rules.

Generally speaking, quatrains don't need antithesis. Whether to use duality is up to the author. Most of our predecessors' quatrains don't have to be antithetical, such as:

Seeing friends off in the mountains, Chai Men is half hidden at sunset.

The grass in spring is green every year, but what about you, my friend Prince? Look at it.

(Wang Wei's farewell)

Lanling wine tulips, jade bowls filled with amber light.

But I got the host drunk and didn't know where it was.

(Li Bai's "Guest Travel")

Some quatrains are antithetical to the first couplet, but not to the last couplet. For example:

During the Three Kingdoms period, you made unparalleled achievements, and you gained a permanent reputation by invading.

This river won't divert the stones from your disposal, and you will always regret that you will destroy Wu's unwise.

(Du Fu's Eight Arrays)

(Note: The antithetical sentences are shown in italics, the same below)

Good years must be remembered, especially when it is orange, yellow and green.
