Comparison to Western Culture: In English, we might say “three in the morning” or “the wee hours,” but these are descriptive phrases, not a single, standard noun for the entire time block. We might vaguely call 4:30 AM “early morning,” but a Chinese speaker would precisely identify it as 凌晨. The American concept of “morning” can start right after midnight (e.g., “The party went on until two in the morning”). In contrast, Chinese draws a much clearer line: 凌晨 is for the dark hours, while `早上 (zǎoshang)` is for when the day's activities actually begin with the light. This reflects a more structured and traditional conception of the daily cycle.
