For the "Fly to Milan" fashion show of Tmall Snow Season, we were mainly responsible for audio‑visual system construction and full‑event on‑site execution. Multiple engineering projectors were deployed along natural snow slopes to create huge immersive dynamic light‑and‑shadow visuals. Array speakers, layered ambient lighting and fixed follow‑spot light systems were planned in an integrated approach. Cable reinforcement and cold‑resistance protection for equipment were implemented for the harsh outdoor freezing environment. Snow‑ground catwalk routes and stage areas were precisely arranged. We kept track of rehearsals, fashion shows and on‑site equipment operation & maintenance throughout the event. Digital light‑and‑shadow effects blended with real snow‑field scenery, delivering a visually stunning outdoor ice‑and‑snow themed launch show.
