The Vietnamese word "nhà giam" refers to a detention facility or prison where people are held, usually because they are accused of committing a crime. It can be translated to "detention prison" or "detention place" in English.
In more advanced contexts, "nhà giam" can be used to discuss issues related to the justice system, human rights, or prison reform. For example: - "Chúng ta cần cải cách nhà giam để cải thiện điều kiện sống cho tù nhân."
(We need to reform the detention prisons to improve living conditions for inmates.)
