Under the Hmong rules/belief and whatever crap.. Can a divorce woman keep the son with her and set up his marriage without the help from the father?
ok i realized that a lot of people here didnt read your question clearly and just started going off in their own world...
to answer your question about... "can a divorced hmong mother conduct her sons wedding according to hmong tradition?"... the answer is "yes"...
how?... depending on which clan the son's spirit was assigned to when the son was born... if the son was assigned to the fathers clan... then she, the mother, would have to have a small shaman ceremony for her son... to have her son's spirit join with her clan and for her clan's spirits to accept her son... as not to anger and disrespect the clans' spirits... (or her new husbands clan...)
why?... like how someone else said here... its about life marriage and death... when the son dies, the son's spirit needs a spirit clan to join with... and so forth with the son's children...
what?... if a different clan, that the son's spirit wasnt assigned to, conducts the son's life marriage and death, then the different clan's spirits will reject the son and bring bad luck to that child...
