When Zhengzhou”seven·twenty"When the extremely heavy rainstorm broke the road, when the Shanghai epidemic tested the medical system, and when the global frequent cyber attacks paralyzed the operation of cities, we had to face up to the fact that urban security has changed from a guarantee condition for development to a prerequisite for survival.

The World Bank's calculations reveal a sobering pattern: every investmentoneYuan disaster prevention funds can avoidsevenPost disaster losses of yuan. Behind this simple number lies the economic logic that urban governance must confront - safety construction is not a cost burden, but the most visionary strategic investment. In today's world of intensified climate change, normalized public health crises, and doubled risks of technological dependence, the traditional passive defense model is no longer sustainable.

The height of urban civilization has never been measured by the number of skyscrapers, but by whether the elderly can safely return home in the rainstorm, whether children can get medical treatment in time under the epidemic, and whether every ordinary person can calmly cope with the crisis. Safety is not a cold indicator, but the warmest commitment to life.
