What rhetorical devices are used in the poem Looking Back?

Looking back on Wang Guozhen

I always wanted to wear it.

The most perfect time.

To realize all colorful dreams.

When I look back at those deep and shallow footprints

Cann't help stomping

I hate that winter is too short and summer is not long.

I really want to put my unfinished youth

Do it again.

You know how to cherish it.

Every dusk, every ray of glow.

Sigh, only sigh, time does not want to go back.

From then on, I never dared to be ignorant and arrogant.

Therefore, the answer: The poem Looking Back is a figure of speech.
