A brilliant firework burst explodes directly above an illuminated waterfront stage. The explosion creates white and golden trails that cascade downward. Below, a massive crowd is bathed in red and amber stage lighting, creating a warm glow across the gathering. A Vietnamese flag is visible waving on the stage structure. Multiple lighting rigs and searchlights beam upward. The waterfront setting and scale suggest this is a major national or cultural festival event in Đà Lạt.
