Walking Marriage

Also, in southwestern China, walking marriages, in which the husband and wife do not live together, have been a traditional part of the Mosuo culture.[22] Walking marriages have also been increasingly common in modern Beijing. Guo Jianmei, director of the center for women's studies at Beijing University, told a Newsday correspondent, "Walking marriages reflect sweeping changes in Chinese society."[23] A similar arrangement in Saudi Arabia, called misyar marriage, also involves the husband and wife living separately but meeting regularly.[24]
