急救不是旁观者知识，而是需要练习的能力。

First aid is not spectator knowledge; it is a skill that requires practice.

2025 年 4 月，我第一次参加 AED / 急救相关培训，系统学习 CPR、AED 使用和基础急救响应。因为未满16周岁，我没有获得证书，但这次训练让我真正动手练习，也成为我继续推动校园急救计划的起点。

在培训中，我练习了胸外按压、人工呼吸、AED 贴片和设备提示流程，也观察到教练如何纠正动作细节。按压的位置、深度、节奏，以及与 AED 操作之间的配合，都直接影响急救效果。对我来说，这次训练是从个人兴趣走向真实行动的重要一步，也成为后来组织线上公开课、制作学习材料和推动校园急救意识传播的基础。

In April 2025, I joined my first AED and first-aid training, where I learned CPR, AED use, and basic emergency response. Before this, I understood first aid mainly through football, sports injuries, and campus safety. The hands-on session helped me realize that emergency response is not only about knowing what to do; it requires repeated practice of movement, sequence, and judgment.

During the training, I practiced chest compressions, rescue breathing, AED pad placement, and following device prompts. I also observed how instructors corrected details such as compression position, depth, rhythm, and coordination with AED operation. This became an important step from personal interest to real action, and later supported my online public session, learning materials, and campus first-aid awareness efforts.
