This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 佱 is uncertain. It visually combines 亼 and 正, but the original meaning and component roles are unclear.
The top 亼 looks like a gathering, and the bottom 正 suggests correctness. Together they might hint at a proper assembly, but the meaning is not confirmed.
For ホウ, imagine a hopeful gathering under the 亼 roof where everyone stands 正 (correctly): hope -> ホウ, though the meaning is uncertain.
