What does it mean for a freshman girl to stay in a hotel alone?

One person must be self-reliant.

It means that no one will interfere with you and you can do whatever you want. Then you need to regulate your own behavior and make certain plans for your future.

When choosing a hotel, try to choose a hotel with a better environment and a formal look. Don't choose a small hotel in an alley. When staying in a hotel, remember to pay attention to the location of the elevator, the location of the corridor, the approximate location of the room, and the emergency exits. It is better to be prepared. After entering the room, be sure to check the doors and windows carefully. If there is any damage, report it for repair or adjust the room in time. Do not leave an opportunity for bad guys to take advantage of. After entering the room, check whether there are hidden pinhole cameras in areas such as socket switches and bathrooms. If a stranger knocks on the door, remember to speak through the door, even if it is a waiter, do not open the door. If you really have a problem, call the front desk. If you are still unsure, just call 110.
