This is an outdoor signage installation for the Sanjiangyuan National Nature Reserve, conceived and designed by artist Ai Song. Our team was responsible for its fabrication and installation. Crafted primarily from weathering steel, the work consists of a continuous combination of hollowed‑out silhouette panels. On the left side, it features silhouettes of wild animals including the Tibetan antelope, while the right side displays the official text for “Sanjiangyuan National Nature Reserve”. Integrating seamlessly with the natural backdrop of the plateau’s snow-capped mountains, the piece stands as a public artwork that embodies both ecological narrative and local identity.
