This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 弶 is uncertain. It visually combines 弓 (bow) with 京, but the original semantic or phonetic role of 京 is unclear.
With 弓 (bow) on the left and 京 (capital) on the right, imagine a bow displayed in the capital, but its true purpose is unknown.
For ギョウ, imagine a bow in the capital being used in a grand ceremony: the ceremony is a 'gyo' event (invented hook: gyo -> ギョウ).
