A few years ago, a journalist reporting on how the Mosuo culture is being affected by the modern world found that many Mosuo men and women were abandoning their traditions in favour of modern Chinese social values. They also had to leave their villages for the larger cities to do this. The senior Mosuo women were apparently very concerned by this. I wonder what the rate of this defection is now. https://en.wikipedia.org/wiki/Mosuo#Modernity
