Hmong people said that use Hmong can't pretend to be dead or to be one of the dead walking because of our traditional background is very strong and it well upset those that we are mocking of and things won't be pretty
Almost correct ... but like they say, "Almost only counts in horseshoes and hand grenades."
Hmong people cannot be portrayed as dead and use his or her own name. As they say,
"Dab ruam, neej ntse." The spirits only know what you tell them. If you say "such and such person is dead," the spirits will come and get them. But if you assume a character's name (which is different from your given name), then you can act dead.
Another "no-no" is to climb into a coffin and play dead. I don't know what happens to the people who have done that for movies, so I can't comment on the outcomes.
