Lugu Lake Lanyue Hotel, on Lugu Lake, follows "Striving for Quality, Not Greedy for Brightness" with restrained lighting, linking travelers to local nature and culture, preserving the lake's essence. No top lighting; light focuses on lower parts and interiors. Public areas use moonlight-like light or embers; drop-offs have "node lights". Interiors use warm light. Windows bring lake night, mountains and stars as "background light". Light fades, letting the lake's atmosphere flow, forming a "light as foil, nature as core" loop.
