The Vietnamese word "đại bác" translates to "cannon" or "gun" in English. It refers to a large, powerful firearm or artillery piece that is used in warfare.
In a more advanced context, "đại bác" can also be used metaphorically to describe something powerful or impactful in a non-literal sense. For example, in discussions about influential ideas or strategies, one might say something is as impactful as a cannon.
While "đại bác" primarily refers to cannons or guns, in some contexts, it could symbolize strength or force, like in discussions about powerful nations or influential leaders.
