The horn is, according to baidu, a beak. Which uh, makes a lot more sense

No, apparently this poem is a chaste woman rejecting a rogue with a wife. Really meanly and sharply too lol. Though Baidu lists a TON of possible POVs and contexts, that was their "summary" explanation. I kind of like this, basically she's saying like, no matter what if you spread rumors to intimidate me or bring me to court, I won't give in and let you imprison me.

First stanza is apparently so weird and obscure that it might be from another poem.
