Wennan Street's qilou shophouses are among the best-preserved examples of early 20th-century southern Chinese commercial architecture in Hainan. The colonnaded ground floors that gave the buildings their name — qilou means "raised building" — shelter pedestrians from rain and sun while providing display space for the shops behind, an arrangement that works as well today as it did when the buildings were new.
The facades show the eclecticism typical of the style: Ionic columns, arched windows, decorative parapets, and occasional Art Deco geometric ornament mix without apparent concern for consistency. The overall effect is lively rather than confused. Most of the buildings are still occupied and still commercial, which gives the street a lived quality that preserved historic districts in more tourist-heavy cities have lost.
