This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
虠 combines 交 and 虎, but its historical origin and meaning are unclear. It may be a variant or a rare character with uncertain development.
The kanji visually combines 交 (mix, intersect) and 虎 (tiger). Without a clear meaning, picture a tiger crossing paths with something, but treat the meaning as unknown.
For コウ, use the reading of 交 (コウ) as a hook: 交 -> コウ, and the tiger 虎 stands beside it.
