name of a Chinese river, name of a Chinese mountain
岷 is a proper noun used in Chinese place names, specifically a river and a mountain. It has no general abstract meaning beyond these geographical references.
岷 combines 山 (mountain) with 民, which likely contributes the sound. It was created as a specific character for the Min River and Min Mountain in China.
The left side is a mountain 山, and the right side is 民 (people). Picture a famous mountain and river in China named after the people who lived there: 岷 is that mountain and river.
For ビン, imagine a bin full of water from the Min River: bin -> ビン, and the mountain 山 watches over it.
