What is the night watchman?

The ancient vigil refers to the activities of herders or cultivators to guard their labor goals at night, and there are also night activities for certain beliefs or commemorative purposes. There is no clear guardian for this kind of behavior, such as the night sacrifice activities to commemorate the deceased relatives in a certain period.

Now the night watchman is the night watchman. He used to be called the night watchman, but now he is called the security guard or doorman. Working at night in the workplace is also called vigil to some extent.
