Yi girls in Daliangshan can marry, or they can marry Han boys. As long as the people in that place don't object, or their parents don't object, that's all. In some places, Han people don't like Yi people to get married. But now the society is open. Generally speaking, such an idea does not exist. If two people work in the city, there is basically no such reason.
