Might have been ARVN, or might have even been VC. Or it could be a personal grudge he had against a business or people hosting it?
Kinda an odd time for him to do that. If it’s anything interesting, it’ll get covered up.
6 Things You Hear Growing up Hmong
Don’t sit on the bag of rice. If you sit on rice, your future children will be born without a butt.
Don’t step on mushrooms. Poj Ntxhoom (a demon) will appear and watch you from atop the trees.
Don’t whistle at night. If you hear something whistle back at you, you may have just awakened a wandering spirit and it will follow you bringing bad omen.
Don’t comb/brush out your hair at night.
Never point to the moon. The moon will come down and slice your ear.
Always tuck your feet in when you sleep. Poj Ntxhoom lurks at the ends of the bed and if you wake up to your feet being tickled, well you know who did it. Poj Ntxhooms are active at the moment right before you fall into deep sleep.
