Developed an integrated space construction solution for Donghao Lansheng’s brand exhibition hall at the CIIE. Curved main stage, multi‑tiered stepped seating areas and surrounding multimedia display cabinets were delivered. Integrated layout of overhead truss lighting and complete audio‑video systems was finished, with precise pre‑embedding of multi‑screen linkage circuits and reinforcement for irregular facade structures. The space can flexibly adapt to various on‑site sessions including theme forums, interviews and interactive experiences. Modular construction efficiently supports frequent content rotation during the exhibition.
