All barricades will fade when education reaches proper level; Tibetans and Hans are all Chinese separated by lack of contact due to geographical difficulties. Those problems are gone now !
@@rcchen5624 yeah,but multiple husband must be the blood-bond brothers,which means the Tibean woman actually married with the whole brother of the family; and one Tibetan man can married with multiple women who must be the blood-bound sisters too, why? cuz usually Tibet is not rich with nature resource for living,so for keepping property they should prevent one family became multiple that could make their economic condition declining and also they have to combat with foreigner such as Chinese for self-defend or invation in the ancient era and if one husband die in the battlefiled the woman won't become widow if she has multiple, so the population won't declining too. if without those ancient tradition in some area of Tibet, they can't survive till now because they will be vanished by other nation such as Han Chinese who have the maginficent mumbers of them.
