strong, just, righteous, peace-loving
侃 centers on a person of upright, unwavering character: someone strong, just, and righteous, whose inner peace comes from moral clarity rather than passivity.
侃 combines 亻 (person) with a right side that likely represents a mouth 口 over flowing water 川, suggesting a person whose words flow with strength and justice. The exact historical development is uncertain.
A person 亻 with a mouth 口 above a river 川: imagine someone standing by a river, speaking strong, just words that flow like the water, unshakable and righteous.
For カン, picture a strong, righteous person who can always be counted on: can -> カン, and their just words flow like a river.
