Yeng先生,黑苗族是确定他们穿的衣服和他们生活的地区。正如你所知道的关于绿色,白色和条纹苗族。这是相同的。我可以告诉你最黑苗族居住在广西和越南北部。关于中国。还记得中国意味着人居住在中国。在中国大多数人是汉族。因为许多部落已经融化成为汉,我估计接近80%的人由于许多战争已经成为汉。我们更与中国比泰国和老挝。想想我们的姓,甚至是一样的汉人不靠近泰国和老挝。 We have the same surname like the Han because some of our ancestor (Hmong) miao has become han chinese. you got it. It's like this country, a lot of india tribe has be come america. you can't tell the different unless you see those people who are still at the reservation.
