The Vietnamese word "chánh sứ" can be translated to "chief envoy" in English. It refers to a high-ranking official or representative who is sent on a diplomatic mission, particularly during feudal times. This term is often associated with significant roles in government or royal missions.
In a more advanced context, "chánh sứ" can refer to the head of a diplomatic mission or a special envoy handling significant international matters. It can also embody the responsibilities of negotiating treaties or resolving conflicts between nations.
While "chánh sứ" specifically refers to a chief envoy, in certain contexts, it might also denote leadership roles in other types of missions or higher offices in traditional governance, depending on the historical era.
