Why can't you marry your family?

Because Yi families have been living on boats, they have formed some customs different from those in land society. In the old society, they were rejected and discriminated by the land people, which also created the tradition of intermarriage between Yi family members.

Tujia nationality is a general term for water residents in coastal areas of China, mainly distributed in Fujian, Guangdong, Guangxi and Hainan provinces. The Jia family belongs to the Han nationality, which has the main customs and habits of the Han nationality, as well as its unique life customs and habits. Because Yi families have no land and live by water, some customs different from the land society have been formed.
