The Yao people practice monogamy and usually don't intermarry with people of other ethnic groups. Some marriages are arranged by parents and a few are realized through free love.

Young people freely choose their spouses mainly through singing in antiphonal style. After observation, comparison and consideration in group singing, a young man may sing with a specific girl in antiphonal style if he takes a liking of her.

Matchmaking is prevalent among Yao people. Even those who choose a spouse via antiphonal singing still need a matchmaker and go through the process of engagement.
