stand side by side, assemble
乑 centers on people standing together in a group: assembling or standing side by side. The idea is collective presence rather than individual action.
乑 is a variant form of 衆, depicting three people (人) standing together to represent a crowd or assembly. The exact historical development is uncertain, but the triple-person structure is a clear visual representation of gathering.
