Wennan Old Street, located in Wenchang, Hainan, took shape around 1912 and was further developed in the 1920s with investments from returning overseas Chinese. It is a classic example of Nanyang-style arcade architecture. Stretching over 300 meters, the street is lined with dozens of East-West hybrid shophouses, blending Southeast Asian influences with the distinctive architectural style of northern Hainan.

In recent years, Wennan Old Street has been revitalized through cultural and tourism initiatives, becoming a window to showcase the intangible cultural heritage of Wenchang to the outside world. The street regularly hosts traditional performances, such as Wenchang puppet shows and coconut carving demonstrations, attracting both domestic and international tourists.
