strong, robust, vigorous
敃 centers on strength and vigor: being robust, powerful, and energetic.
敃 combines 民 (people) with 攵 (action hand), possibly suggesting strength exerted by or for the people. The exact historical development is uncertain.
The left side 民 (people) and right side 攵 (action hand) together suggest people working with strong hands, showing vigor and robustness.
For ビン, imagine a strong person lifting a heavy bin: bin -> ビン, and their robust strength moves the bin easily.
