The Vietnamese term "gái giang hồ" is a noun that translates to "demi-mondaine" in English. It refers to a woman who is often associated with a lifestyle that includes being a part of the nightlife or underworld, typically involving activities that may be considered morally questionable, such as sex work or being part of a bar or club scene.
In literature or discussions, "gái giang hồ" may be used metaphorically to refer to women who break societal norms or challenge traditional roles, even if they are not involved in nightlife or illegal activities.
While the primary meaning relates to women involved in nightlife or potentially immoral activities, it can also be used in a broader context to describe any woman living a free-spirited or unconventional lifestyle.
