luck, seek, desire
僥 centers on the idea of unexpected fortune: luck that comes by chance, or the act of seeking something desired in the hope of a lucky outcome.
僥 combines 亻 (person) with 堯, which likely contributes the sound and may relate to the idea of seeking or luck. The exact historical development is uncertain.
A person (亻) beside 堯, which looks like a pile of earth (土) with legs (儿) — imagine someone digging for buried treasure, hoping for luck and seeking what they desire.
For ギョウ, imagine a lucky person finding a gyoza (ギョウザ) shaped like a treasure chest while digging: gyo -> ギョウ, and the luck brings them what they sought.
