The image is a photograph of a white poster hanging on a green wall. The poster is titled "EPT 2021/3/27" in Chinese and appears to be a map of a building. The map is in the center of the poster and shows the layout of the building with various rooms, corridors, and other features. The text on the poster is written in both English and Chinese, and there is an illustration of a robot on the bottom right corner. The background of the image is blurred, but it seems to be an indoor space with plants and a building visible in the background.
