Origin Story
苏轼被贬黄州，在赤壁写下名篇《赤壁赋》。其中“寄蜉蝣于天地，渺沧海之一粟”一句，表达了他在面对宇宙洪荒时，感受到自身渺小的感慨。他如同大海中的一粒粟米，微不足道，却也怀揣着对人生的追求与思考。他虽身处逆境，却依然心怀抱负，努力在有限的生命中，留下自己的印记，这才是人生的意义所在。
Su Shi was demoted to Huangzhou, where he wrote the famous piece "Chibi Fu" in Chibi. In it, the line "A mayfly in the heavens and earth, a drop in the ocean," expressed his feelings of insignificance when facing the vastness of the universe. He, like a grain of millet in the sea, was insignificant, but he still held onto his pursuit and thoughts about life. Even though he was in adversity, he still harbored aspirations, striving to leave his mark in his limited life; this is the meaning of life.
