The image shows a group of people gathered in a large room with a high ceiling and white walls. The people are of different ages and ethnicities, and they appear to be engaged in a protest or demonstration. In the center of the image, there is a person holding a sign that reads "B5.16" in Chinese characters. The person is wearing a red and white striped shirt and a baseball cap. To the right of the person holding the sign, there are several other people, some of whom are also holding signs. The room appears to be well-lit with natural light coming in from the windows.
