To me I feel that this is a bad thing to like or even married someone of the same last name, but like everyone says we learned that since we were little so it's embedded into our head. While others feel that it's dumb and stupid they have to think of the elders. What will they say if you go against your will, I have a cousin he is a Vang and married a Fang which is a big NO, NO!! but they still did since they believed there is no blood relationship between them just the old hmong saying. Will they went against their will and now her family disowned her. They won't talk to her or even see her, if people talk about them her parents say they have no such daughter.
Yes love does take you into a place you don't want to get away from but sometimes you have to see that maybe the elders had something behind this you can't married someone of the same last name or even married the last name you are banned from. I believed it's better to have your parents trust and love since no matter what they are there for you, it's just sad to hear that your parents disowned you because you married someone of the same last name.
But nowadays I feel like it doesn't matter no more since the elders are passing away and the new generation are not keeping the culture alive.
