On March 28, 2025, a powerful earthquake struck Myanmar, causing extensive damage across the country and leaving over 140 people dead. The full extent of destruction was initially unclear, particularly in Myanmar, where a civil war has further complicated rescue and recovery efforts. Neighboring Thailand also felt the impact, with at least six fatalities in Bangkok following the collapse of a high-rise under construction. While this tragedy unfolded, it raises a crucial question: how do some countries successfully build earthquake-resistant structures? One of the best examples is Taiwan.

Throughout the history of hydraulic construction, the Chinese have relied on folk wisdom to protect bridge foundations and piers from water erosion and the impact of currents. One of the most unique and effective methods is the use of oysters—marine organisms with the ability to adhere firmly to hard surfaces, forming a natural protective layer for structures. Based on real-world observations, this method has gradually been researched and applied in modern construction, becoming a sustainable building solution.
