What does it mean to get married formally? Is it true that Christine, a black man, has been passed on as a marriage partner again?

Formal marriage, also known as mutual aid marriage, refers to a wedding or legal marriage procedure with another person for a certain purpose, but it is actually only a nominal husband and wife status, with no substantive content. For example, a gay man and a lesbian hold a wedding and form a family; Or some people go to other places to work and immigrate; Or to enjoy the benefits and rights granted by the government to married people; Or forced to follow the wishes of family members and marry the opposite sex. After marriage, it is nominal.
