Haikou’s Arcade Old Street, dampened by drizzle, holds Nanyang memories. A treaty port since 1858, it linked Nanyang and inland. In 1924, Hainanese overseas Chinese built "arcade buildings" (shops below, corridors above) with volcanic rocks, blending Baroque carvings and Nanyang windows.​ In the photo: colorful lanterns on bluestone, slow motorcycles, strolling pedestrians. The old "shop rows" vibe lingers in mist. A "National Top 10 Historical Street" (2009), it’s still a living part of today.
