The video shows a man standing on a stage in front of a large audience. He is wearing a blue shirt and holding a microphone in his hand. The man is speaking into the microphone, and his hands are moving as he talks. The audience is seated in rows, and they are watching the man intently. The stage has a large screen behind the man, which displays the words "TEDxHongKong" in white letters on a black background. The lighting in the room is dim, and the focus is on the man speaking.
