The Da Nang International Fireworks Festival 2025 (DIFF 2025) concluded with spectacular nights of performances along the Han River, marking an emotional and breakthrough season. In that vibrant atmosphere, Team Z121 – under the Vietnamese Ministry of National Defense – continued to affirm its position on the international stage with meticulously choreographed, creative fireworks displays rich in Vietnamese identity.

International rounds: The soldier’s spirit in every firework beat

Entering DIFF 2025, Z121 presented a performance script that was comprehensively and professionally invested in, from thematic structure, musical composition, and lighting effects to the coordination of high-, mid-, and low-altitude fireworks.

Every firework type and ignition point was precisely calculated to form a seamless artistic whole. Against a specially composed musical backdrop, Z121 told the story of Vietnam through color, rhythm, and light—reflecting the resilient military tradition alongside the image of a confident, modern nation with an ever-stronger aspiration for global integration. Beyond its rich palette of effects, the team placed particular emphasis on perfect synchronization between fireworks and music—a defining hallmark of high-level technical teams.

The Grand Finale: When fireworks become a storytelling language

On the DIFF 2025 Grand Final night, Z121 delivered a remarkably refined performance, clearly demonstrating a comprehensive upgrade—from battlefield layout design to the selection of signature fireworks researched and manufactured in-house.

The show opened with layered, three-tier fireworks sequences that transitioned smoothly, creating a continuous and emotionally engaging rhythm of light. Over the Han River, three-dimensional light effects generated a strong sense of depth, making each firework stream appear to move independently. Climactic moments were precisely timed to musical beats, producing powerful, fully immersive bursts where sound and light merged seamlessly. Notably, the signature “line-drawing” fireworks technique – a distinctive Z121 hallmark – created soft, flowing trajectories across the sky, resembling vivid brushstrokes of light. The fusion of technology, technique, and artistry resulted in a performance that left on-site audiences and millions of online viewers alike overwhelmed with pride and emotion.

Z121 – From national defense foundations to international competitive excellence

As the only unit operating professional fireworks production lines under defense standards, Z121 adheres to modern, absolutely precise, and highly secure technical processes.

Behind each display stands the collective effort of experienced engineers, workers, and soldiers, combined with flexible creativity in designing performance firework compositions. Through years of participation in international arenas, Z121 has forged its own distinctive identity and competitive composure—an unmistakable signature that sets it apart. This year’s festival once again confirmed that Z121 fireworks not only meet global artistic standards but also carry the Vietnamese spirit, resonating with friends around the world.

Vietnamese pride: Light from the hands of soldiers

Each firework ascending into the Da Nang sky was not just an artistic moment, but also a beautiful image of the peacetime soldier—disciplined, creative, and responsible. From national defense missions, Z121 has brought the light of fireworks closer to everyday life, becoming a source of joy for millions of Vietnamese families and a lasting impression for international visitors. DIFF 2025 has come to an end, but the values Z121 leaves behind continue to shine: a resilient, modern Vietnam, increasingly radiant on the global fireworks map.
