The Vietnamese word "kinh thành" refers to a "capital city" or "imperial city." It is often used to describe a city that serves as the political and administrative center of a country or region, especially in historical contexts when referring to cities that were once the capitals of dynasties.
In more advanced contexts, "kinh thành" can be used to discuss urban planning, historical architecture, or the significance of a city in the cultural identity of a nation.
While "kinh thành" primarily means "capital city," it can also imply a sense of grandeur and historical importance, especially when associated with ancient cities that served as the heart of a nation.
