I don't even think these 'kev caiv' evolved to represent the Hmong culture and traditions, Hmong Knight. Even if these 'kev caiv' aren't relevant in today's Hmong generation, I don't necessarily believe we are losing our roots because of it.
I honestly think that these 'kev caiv' came into light because somewhere, somehow, along the road in the past, someone made a bad decision or didn't like the way something went and they just came up with these 'kev caiv,' or what I would call, regulations to try and control things from getting out of hands.
