On November 26,2025, a devastating fire erupted at Hongfu Garden in Tai Po, Hong Kong. As of December 9, the incident had claimed 160 lives, with approximately six people still missing. This deadliest fire disaster in Hong Kong in recent years has not only caused profound grief but also prompted deep reflection on building fire safety design. From a professional fire safety perspective, the tragedy exposed systemic failures in three critical aspects of fire protection design. Had any one of these three safeguards been effective, the severity of the tragedy could have been significantly mitigated or even entirely prevented.
