For the “Fly to Milan” fashion show during Tmall Snow Season, we were responsible for audio‑visual system construction and full‑event execution. Multiple engineering projectors were deployed along natural snow slopes to generate huge immersive dynamic light‑and‑shadow visuals. Array speakers, layered ambient lighting and dedicated follow‑spot systems were integrally arranged. Cable reinforcement and cold‑resistance protection were implemented for harsh outdoor cold conditions. Snow‑ground catwalk routes and stage areas were precisely planned. We followed up rehearsals, shows and on‑site equipment maintenance throughout, blending digital light‑and‑shadow with real snow‑ground scenery and delivering a visually stunning outdoor snow‑themed fashion launch show.
