This ancient city would be translated to English as "this ancient city". "古城" (gǔ chéng) is a Chinese term that literally means "old city" or "ancient city". In English, "ancient" typically refers to something that is very old, possibly dating back to the earliest civilizations or the historical period before writing systems were developed. A city can be considered ancient if it has a long and rich history, with buildings and artifacts that have survived from earlier times.
