Indigenous Knowledge
70%Hong Kong’s indigenous Hakka and Hoklo communities historically used non-flammable earthen plasters and bamboo reinforcement in rural housing, techniques now validated by modern fire science. These practices were systematically displaced by mid-20th century concrete construction, yet their principles—such as compartmentalization and natural ventilation—remain relevant for retrofitting dense urban environments. The absence of these methods in contemporary safety discourse reflects a broader erasure of local ecological knowledge in favor of imported, profit-driven building codes.
