rope
麼 centers on a rope or cord, likely a thin twisted line used for tying or binding.
麼 combines 麻 (hemp) with 幺 (fine thread), suggesting a rope or cord made from hemp fibers. The exact historical development is uncertain, but the component relationship is plausible.
Hemp 麻 is twisted into fine threads 幺 to make a rope. Picture the outer hemp plant being processed into the inner thin cord.
For ビ, imagine a bee buzzing around a hemp rope: bee -> ビ, and the bee is attracted to the rope made from hemp.
