"Poov" here, or in general and overall, means offerings, money, goods, gifts; precisely it means the food and drinks brought for the wedding feast.
Another way to use "poov" in Hmong is: Nod yog koj poov. (Here are your goods/shares/gifts.) Koj yeej los pob poov tag lawm. (Did you win or lose everything?) Yes, "peev" is another form of the word, but within a traditional setting (wedding), "poov" is the preferred choice for aesthetic formality.
