Steeped in the architectural traditions of Lijiang, Yunnan Province, this antique elm lattice screen reflects the refined artistry of late imperial Chinese woodworking. Hand-carved geometric coin patterns and endless knot motifs symbolize prosperity, harmony, and longevity, while traditional mortise-and-tenon joinery showcases exceptional craftsmanship. A rare ink inscription reading “Maritime Customs Back Gate” connects the panel to a historic Customs House, offering remarkable provenance and cultural significance. Its warm, weathered patina preserves the character of an architectural element that once united beauty, symbolism, and everyday function.
