Li bi is a formal expression in Chinese, written with the characters for ritual and finished, and traditionally spoken to mark the conclusion of a ceremony, from school assemblies to formal gatherings. As a standalone soundboard clip it has no widely documented viral origin, and its appeal comes from that contrast: a dignified closing line lifted out of its serious setting. Online creators reuse it as a compact ending cue, a way to declare a segment, joke, or performance officially over without adding further explanation.
