This is a video of a nighttime equestrian parade, likely a ceremonial event, taking place in Da Lat, Vietnam. A group of individuals on horseback, many holding red flags, are proceeding across a brightly lit, flat surface. The riders are dressed in what appears to be formal attire, including helmets. The setting suggests an outdoor stadium or large open area, with spectators visible in the background, seated in bleachers. The scene is illuminated by artificial lighting, casting distinct shadows. The presence of a large audience and the synchronized movement of the riders and horses indicate a structured performance or procession. The overall atmosphere appears to be one of formality and spectacle.
