What 疻 means
It describes a bruise with no break in the skin.
A legal passage from China’s Han dynasty, an early empire, uses 疻 for an injury caused by a blow.
The early Chinese dictionary Shuowen Jiezi preserves the same definition.
Classical Chinese legal vocabulary; in a casual message, it needs context.
Without a gloss, readers may miss its specific historical sense.
