How does a matriarchy really work? Argentinian writer Ricardo Coler decided to find out and spent two months with the Mosuo in southern China. "Women have a different way of dominating," the researcher told SPIEGEL ONLINE.

SPIEGEL ONLINE: Mr. Coler, you are from Argentina, where macho behavior is not exactly unheard of. What was it like living for two months in the matriarchical society of the Mosuo in China?

Coler: I wanted to know what happened in a society where women determine how things are done. How do women tick when, from birth onwards, their societal position allows them to decide everything? We men know what a man is, we put that together quickly -- but what constitutes a woman? Although, I didn't get any wiser on that point.
