The video shows a night-time event with a crowd gathered behind a railing. In the background, there are bright lights, a large screen displaying content, and several white police cars with flashing lights. Some police officers are visible near the cars and in the crowd. A large red banner with Vietnamese text is also present. Further in the background, there is a scaffolding structure with a person on top. People in the crowd are holding up their phones, suggesting they are recording or taking pictures of the event. The scene appears to be an outdoor public gathering.
