What does "type marriage" mean?

It's "formal marriage" Formal marriage, as its name implies, is that marriage has only form and no substance. This is a mode of mutual marriage between gay men and lesbians in economically developed cities such as Beijing, Shanghai and Nanjing in recent years, that is, a gay man and a lesbian hold a wedding and form a family. On the surface, this is a normal family composed of a man and a woman, but in fact, both husband and wife are physically and mentally independent. They only rely on the form of marriage to resist external pressure and get the freedom of love under the umbrella of marriage.
