I wonder about the caption....The women do not appear to be Tibetan...Tibetans are quite different than Han Chinese physically.
Was that the title from the original Korean language news service?
Yes, the article says they are Tibetan. I met Tibetans who look different as you said. But I am not in a position to make a definite determination as to whether they are Tibetan or not.
I am more surprised that such photos were so successfully exported from the country....
