Taipei, Aug. 12 (CNA) Hualien and Taitung counties in eastern Taiwan held urban resilience air defense drills Wednesday, practicing evacuation and sheltering procedures without conducting a simulated mobile network slowdown as implemented in central Taiwan earlier this week.

In Taitung, passengers at the train station were directed to a roughly 30-meter-long underground passage. Taitung County Magistrate Yao Ching-ling (饒慶鈴) said the exercise revealed areas that needed to be reviewed and improved, providing useful information for future emergency preparedness.
