The word "崇祯" is formed from the character "崇", which is structured with "山" (mountain) above "宗" (ancestor) to imply loftiness or reverence, and "祯", which is structured with "示" (altar) beside "贞" (virtuous) to imply auspiciousness; together they create a compound meaning "lofty auspiciousness", used specifically as the era name for Emperor Zhu Youjian of the Ming Dynasty.
