最近经常想起⼩时候（⼤概是初中）⼀次夏⽇的午休，躺在⼀块⽊板上睡了很久，燥热、昏沉、⽆⼒，世界好像在那⼀刻停⽌了，那时的⾃⼰，多么⽆忧⽆虑？

Recently, I often think back to a summer afternoon during my childhood (around middle school). I lay on a wooden board and slept for a long time, feeling hot, drowsy, and powerless. It seemed like the world had stopped at that moment. How carefree I was back then!
