Why should I leave a toilet light when staying in a hotel?

According to feudal superstition, ghosts often enter toilets and doorways. When a ghost enters a field, the lights in the whole room will not be lit, and the toilet is often built in the middle of the door and bedroom. This means that as long as a ghost enters at the door. People in the room will know for the first time and make emergency preparations. The above is the statement of feudal ideological education

According to the situation of staying in a hotel, it is often that after the curtains are drawn at night, if you are thirsty and hungry in the middle of the night, it will be dark if you want to go to the toilet. Because you are not familiar with the surrounding environment, you will often throw cups, telephones and other things on the ground and you can't find the room light switch. Breaking and entering is also easy to hit the wall. Leaving a light in the toilet will make me see things around me when I wake up in the middle of the night, and it won't interfere with my sleep.
