In this video, we see a man wearing an orange shirt and a black cap. He is standing in front of a wall with two white plates on it. The man is holding a piece of paper with the number 3 written on it. He is talking to the camera and pointing to the number 3 on the paper. He then covers the number 3 with his hand and shows the number 7 on another piece of paper. He repeats this action several times, covering the number 3 with his hand and showing the number 7. The man seems to be demonstrating something, but it is not clear what he is trying to convey.
