The Yaos have intriguing marriage customs. With antiphonal singing as a major means of courting, youngsters choose lovers by themselves and get married with the consent of the parents on both sides. However, the bridegroom's family used to have to pay a sizeable amount of silver dollars and pork as betrothal gifts to the bride's family. Some men who could not afford the gifts had to live and work in the bride's families and were often looked down upon.
In old Yao families, the mother's brothers had a decisive say in crucial family matters and enjoyed lots of other privileges. In several counties in Guangxi, for example, the daughters of the father's sisters were obliged to marry the sons of the mother's brothers. If other marriage partners were proposed the betrothal gifts had to be paid to the mother's brothers. This, perhaps, was a remnant of matrilineal society.
