strong, robust, tough
暋 centers on strength and resilience: being robust, tough, and able to endure or exert effort.
暋 combines 敃 (likely phonetic and possibly related to effort) with 日 (sun), but the exact historical development is uncertain. The character is rare, and its component origins are not well documented.
The top 敃 looks like a person exerting force, and the bottom 日 is the sun. Imagine someone working hard under the hot sun, becoming strong and tough.
For ビン, picture a strong, robust person lifting a heavy bin under the sun: bin -> ビン, and the effort makes them tougher.
