Land Of The Walking Marriage - Mosuo people of China
"Marriage as other cultures know it is uncommon among the Mosuo; they prefer a visiting relationship between lovers--an arrangement they sometimes refer to in their language as sisi (walking back and forth). At about the age of twelve, a Mosuo gift is given a coming-of-age ceremony, and after puberty, she is free to receive male visitors. A lover may remain overnight in her room but will return in the morning to his own mother's home and his primary responsibilities. Children born from such a relationship live with their mother, and the male relatives responsible for helping to look after them are her brothers. Many children know who their fathers are, of course, but even if the relationship between father and child is quite close, it involves no social or economic obligation. And lovers can end their relationship at any time; a woman may signal her change of heart by simply no longer opening the door. When speaking Chinese, the Mosuo will call the sisi arrangement zou hun (walking marriage) or azhu hunyin (friend marriage, azhu being the Mosuo word for friend); nevertheless, the relationship is not a formal union.
... we asked A Long what he thought about the sisi system. "`Friend marriage' is very good," he replied. "First, we are all our mother's children, making money for her; therefore there is no conflict between the brothers and sisters. Second, the relationship is based on love, and no money or dowry is involved in it. If a couple feels contented, they stay together. If they feel unhappy, they can go their separate ways. As a result, there is little fighting." A Long told us that he used to have several lovers but started to have a stable relationship with one when she had her first child."
