Xianbei, a network term, namely ancestor, comes from the Japanese honorific title: ancestor, which frequently appears in various Japanese literary works.

senbei (English senbei or sembei) is a Japanese rice fruit. They come in all shapes, sizes and tastes, usually salty, but also sweet. Xianbei is often accompanied by green tea as a casual snack, and is provided to visiting guests as a polite refreshment.

Xianbei also refers to ancestors in Japanese, and in some contexts, it refers to ancestors of wild animals (the hero of a midsummer night's dream).
