The Mosuo are one of the few matrilineal and matriarchal people in the world, so it seems an excellent choice for this sort of "culture clash" study. Han, for those who don't know, are mainstream Chinese, over 90% of the population of China. Mosuo are also arguably matrilocal, in that they practise what is translated as "walking marriage": the woman stays in her mother's home all her life, and her boyfriend/partner/non-husband visits overnight, returning to his mother's household in the morning. This was all very fine and well when they lived in mountainous isolation, but over the past generation, with China's modernisation, roads and tourists have come to Lake Lugu, and guess what, a lot of outsider men want to come and sample Musuo life for a night... and are willing to pay. So by 2013 there was "a red light district where mainly south-east Asian prostitutes dress in Mosuo costume, acting out tourists' fantasies."
I remember reading a memoir by a girl who grew up there before the roads, and left as a young woman. I just went to look up its title and found that Wikipedia has a whole article on the women. And the book is called Leaving Mother Lake: A Girlhood at the Edge of the World by Yang Erche Namu.

Sorry if this is seen as thread hijacking but I love learning about strong women, and strong cultures, around the world.
