Never knew. But I've read this book written by a Harvard doctor that in Okanagan japan, the people there look more khmer than japanese. Okanagan island is across the sea from cambodian. Okanagan dont consider themselves Japanese.
No such thing as race to me. We all originated from the same "Eve."
khmer people are first O asian genes people.
if you like,i can introduce chinese culture and history to you to proff what i believe.
Chinese han are sino-tibetans(Include Qiang,bai,yi,tibetans),our root is in yunnan and tibetan or you can call us tibetan-burmo.
before shang dynasty,is a time full of legend ad tribe war.
you guys always see chinese drama mention the XUAN YUAN(轩辕),or Dragon this Dragon that.
Xuan Yuan is surname of Han people clan HuxXu. Yan Di and Huangdi surname are Xuayuan,so chinese people worship Xuan yuan,is same as we worship our forefather Huang Di.
Nuvwa and Fuxi belong are blong to East Yi,there is a book called SHAN HAI JING,if writen about chinese pre-history lengend.
Dragon is mixed from Xuanyuan (ALSO called HUAXU 华胥tribe) AND east yi tribe,is chinese huaxia(xuanyuan tribe)race totten.
before 6000years ago, chinese peoplelive in SEA,but one day we are left our home to go north,which live in Tibetan nd Gansu,during that time,we are becom 3 main tribe (Xuanyuan huaxu, huangdi people. Shennong yuxion Yandi people,the last one is called EastYi,which is shandong chin today).
3 tribs are alway have war,and han chinse are worship kunlun mountain and make the book SHAN HAI JING,chinese have a drama called SOU SHEN JI,is all came from SHAN HAI JING.
so,that is why you guys always se chinese drama mention xuanyuan,kunlun mountain and dragon etc,because kunlun and xuanyuan tribe is eveything start with.
i believe chinese han (华夏,轩辕)are came from SEA,from o2 people,o2 people today are Viet and Combodia
