Origin Story
从前，有一个年轻的书生名叫李明，他从小在书香门第长大，很少接触社会，少不更事。一次，他进京赶考，路上遇到一位江湖骗子，骗子见李明衣着华贵，便上前套近乎，谎称自己是朝廷官员，要帮李明走捷径。李明轻信了骗子的话，结果被骗走了所有盘缠。这次经历让李明明白，自己少不更事，容易上当受骗。他痛定思痛，决定以后多学习，增长见识，不再轻信他人。他刻苦学习，最终金榜题名，成为了一名优秀的官员，为国家做出了贡献。
Once upon a time, there was a young scholar named Li Ming. He grew up in a scholarly family and had little contact with society. He was inexperienced. One time, he went to Beijing to take the imperial examinations. On the way, he met a con man. The con man saw that Li Ming was richly dressed, so he approached him and pretended to be a court official. He offered to help Li Ming find a shortcut. Li Ming believed the con man and ended up being robbed of all his money. This experience made Li Ming realize that he was inexperienced and easily deceived. He decided to study hard to gain knowledge and not be so gullible anymore. He studied diligently and eventually passed the examination, becoming a successful official who contributed to his country.
