Origin Story
在古代的中国，一个名叫李明的年轻书生，从小就失去了父母，依靠着亲戚的接济勉强过活。他勤奋好学，但因为家境贫寒，无法支付昂贵的学费，只能依靠着借来的书籍和老师的施舍，刻苦学习。为了生活，他不得不去茶馆做工，白天帮着老板跑腿，晚上则利用微薄的收入购买灯油，在昏暗的灯光下读书。就这样，他坚持不懈地学习，终于在科举考试中取得了功名。从此，他步入了仕途，为国家效力。虽然他出身寒微，一开始一无所有，但他凭借着自己勤奋努力，最终获得了成功。
In ancient China, a young scholar named Li Ming, lost his parents at a young age and barely survived by relying on the support of his relatives. He was diligent and loved to learn, but due to his poverty, he could not afford expensive education. He had to make do with borrowed books and the alms of his teacher and study diligently. To make a living, he had to work in a teahouse. During the day, he helped the owner run errands, and at night he used his meager income to buy lamp oil and read under dim lights. In this way, he persisted in his studies and finally achieved success in the civil service examination. From then on, he entered the officialdom and served his country. Although he came from a humble background and started with nothing, he ultimately achieved success through his hard work and dedication.
