Origin Story
从前，在一个繁华的都市里，住着一个名叫阿强的年轻人。阿强天生丽质，相貌堂堂，走到哪里都引人注目。但他却胸无大志，只沉迷于穿戴华丽的衣衫，打扮得花枝招展，四处炫耀自己的外表。他把时间都花在了打扮上，却忽视了学习和工作，结果一事无成。一天，阿强参加了一个重要的宴会，他精心打扮，穿着最华丽的衣服，希望能给众人留下深刻的印象。可是，当他开始发言时，却发现自己知识贫乏，表达能力差，说得前言不搭后语，让在场的人都感到失望。大家这才明白，阿强只是徒有其表，实际上是一个空壳子。这个故事告诉我们，人不能只注重外表，而要注重内在的修养和能力。
Once upon a time, in a bustling city, there lived a young man named Aqiang. Aqiang was naturally handsome and attracted attention wherever he went. However, he was aimless and spent his time dressing in fine clothes and showing off his appearance. He devoted his time to dressing up but neglected his studies and work, resulting in nothing. One day, Aqiang attended an important banquet, meticulously dressed in his finest clothes, hoping to impress everyone. But when he started to speak, it became clear that he lacked knowledge and had poor communication skills. His speech was incoherent and disappointed everyone present. People realized that Aqiang was only good-looking but essentially empty. This story teaches us that we should not only focus on appearance but also on inner cultivation and ability.
