The phrase sheng qi wan bi is a standard announcement used in Chinese-speaking schools and official gatherings to mark the end of a flag raising ceremony. Once the flag is raised and the formal part is finished, the host or announcer says the line so attendees know to leave in order. Short clips of the announcement circulate online as a reaction sound because the solemn delivery contrasts with everyday situations. Creators reuse it whenever a small task needs a disproportionately formal sign-off.
