Check into a hotel

Say you are unhappy, even if your girlfriend has an ID card, it is strictly illegal for you to stay in such a hotel without getting married. But in fact, the problem will not be very serious. First, the police do not have such a large police force to make rounds. Generally, the probability of hotels encountering rounds is very low, so don't worry too much. Even if you find out, you and your girlfriend can explain each other's situation clearly, and the police won't be too hard for you. Don't worry too much. I wish you a happy life.
