Your Chinese name is "丽娜" , ( 麗娜 \ Line ) So I think your Vietnamese is "Lệ na" Or your Chinese name.（Traditional） Your Chinese name is your Korean \ Japanese \ Vietnamese \ Malaysian \ Singaporean name. ^_^

I think, It's "Tuyến". Robert, you are good, but "Đường dây" is not a name.

Well i don't think vietnamese has different name translations, because i know my name, Robert, doesn't even mean anything in vietnamese, as i was told :P if im wrong then i'm sorry but the vietnamese word for line, like a straight line is "Đường dây"
