Origin

This character combines moon (月) on the left with a component suggesting closure or barrier (关) on the right. In ancient Chinese, the moon represented something celestial and elevated, while the right component suggests containment or authority. Together, these parts were meant to evoke something exalted and set apart — the kind of dignified, elevated speech befitting an emperor speaking about himself. Over time, the character came to be used as the imperial first-person pronoun, a way for rulers to refer to themselves with majestic authority rather than as ordinary people.
