Here is a detailed description of the video: **Scene:** The video appears to be filmed in a university lecture hall or auditorium. The focus is on the stage area. There is a large LED screen in the background displaying text in Chinese, identifying the event as the "11th National University Student Medical Innovation Competition." The date 2025年4月26日, which translates to April 26, 2025, is visible on the screen. **People:** Several individuals are present. Some are seated in the audience, facing the stage. Other people are on the stage: * A speaker is standing behind a podium, reading from documents. * Other people are standing nearby the speaker, with some leaving the stage. **Objects:** * A podium with a document on it. * An LED screen displaying event information. * Chairs arranged in rows for the audience. **Actions:** People exit the stage. A man stands behind the podium, looking down at a document and speaking. **Interactions:** Some attendees appear to leave the auditorium. There is no clear communication between people, but the person stands at a podium and speaks. **Environment:** The room is lit with overhead lighting. The walls are a light color. The general atmosphere appears formal. The foreground shows the backs of the heads of members of the audience, and is therefore out of focus.
