The Vietnamese word "đại bản doanh" can be translated to "general headquarters" in English. It refers to the central location or main office of an organization, especially in a military or large corporate context. This is where important decisions are made, and where leaders and key personnel work.
In more complex discussions, "đại bản doanh" can be used metaphorically to describe any central hub of activity, not just military or corporate settings. For instance, you might refer to a major university's administration office as its "đại bản doanh" when discussing academic policies.
While "đại bản doanh" primarily refers to a headquarters, in a more abstract sense, it can also imply a place of control or a major center of operations for any activity or organization.
