Do men and women need marriage certificates to open a big bed room?

I don't need it anymore. According to the check-in requirements in the Measures for the Administration of Hotel Special Industries, I only need to provide my ID card, but other documents may not work. The ID card is the only valid document.

As for the two, in principle, they must register their identity cards.

One card per person, verification registration, real-name registration, instant upload. This is the basic requirement for front desk registration.

Originally, hotels or inns required unmarried men and women to show their marriage certificates in the same room in principle, but they were in business, so they were given money to live in.
