Windows frame yet more windows, undulating rooflines recall waves, and a closed corridor opens out into a tranquil pool this intriguing garden. The compound provides an endless array of architectural surprises: in a corner an unexpected skylight illuminates a planted nook; windows are placed to frame bamboos as perfectly as if they were painted. The Mandarin Duck Hall is particularly impressive, with a picturesque moon gate engraved with vines and flowers. In the back of the garden stands a 70-foot-tall rock moved here from Lake Taihu. Occasional solo musical performances on erhu and zither enliven the halls.
