Walking slowly up the tree - lined ramp in Fanghu Lake Scenic Area, at the end, a grey fair - faced concrete curtain wall emerges as if it has grown naturally in this environment. The strip - shaped openings of varying lengths and widths on the wall sieve the dancing tree shadows into a flowing poetic movement of light and shadow. They are like the mottled marks cast by the branches and leaves, and also resemble the hazy traces of falling drizzle. This "concrete veil" is not only a barrier of the building but also a poetic harmony between nature and privacy. It skillfully conceals the interior space while introducing the changing light, shadow, and greenery of the four seasons. Here, ventilation and lighting coexist. When the gentle breeze blows, the tree shadows sway lightly on the wall. The restroom quietly blends into the tranquil picture scroll of Fanghu Lake, becoming a hidden scenic spot that perfectly integrates practical functions with aesthetic charm.
