Which item in your emergency kit turned out to be less useful than expected? / 应急包里什么东西后来发现没有想象中有用？

Explain what you replaced it with and why. Do not present one household’s kit as universal; climate, health, pets, mobility, and local hazards matter. 请说明你后来用什么替代、为什么。每个家庭受气候、健康、宠物、行动能力和本地风险影响，不存在唯一通用清单。
