The Vietnamese word "giới nghiêm" translates to "curfew" in English. It refers to a regulation or rule that restricts people from being outside during certain hours, typically at night. This term is often used in the context of security measures, especially during emergencies or in situations requiring public safety.
While "giới nghiêm" primarily means curfew, it can also imply a broader sense of restrictions on freedom or movement, depending on the context.
