Is it illegal for the epidemic prevention and control police station to verbally warn?

Verbal warning is an administrative punishment, not a criminal punishment, and generally there is no criminal record.

There are six kinds of administrative sanctions from light to heavy, namely warning, demerit recording, demerit recording, demotion, dismissal and dismissal. Administrative warning means to remind people not to commit another crime, which is a disciplinary action. It can be oral or written, and it is selected and applied by the disciplinary organ. Warning is generally applicable to minor administrative violations and is the lightest administrative punishment.
