Is it reasonable to lock the hotel door?

If the hotel door is not locked, it means that the anti-lock function of your room is damaged. Call the front desk of the hotel to explain the situation quickly, and it is reasonable to ask the hotel to change or upgrade your room on the grounds of safety. As the "home" of guests, hotels still have strong privacy. All rooms must have lock function. If the door is not locked, the guest can refuse to stay in this room.
