You can try to recite your works, carefully understand the feelings you should pay and have, and then look at your poems, cadence, length and so on. I loved writing poetry many years ago, and no one taught me. I will naturally. If you can't express what you want to express, you have nothing in your stomach.
Writing for the sake of writing poetry is a very boring thing. If you really have something to express in your chest, unless you haven't read a book and don't know how to organize the language, you can naturally express it.
Put a few words in a line, put a few short sentences, and follow the mood where to branch. There are no certain rules. Poetry is an extremely emotional thing and cannot be mass-produced.
