The image shows a large screen in a lecture hall with a presentation on it. The screen displays an image of a building with the text "Main Library" above it. Below the text, there is a subtitle that reads "Enter with Student ID: B1-Study Corner (1-4F Books and materials)". On the right side of the screen, there are two women standing on a stage, one holding a microphone and the other holding a book. The audience is seated in rows of chairs, facing the screen and attentively listening to the presentation. The walls of the lecture hall are decorated with Chinese characters.
