Origin Story
很久以前，在一个偏远的小山村里，住着一对勤劳的兄弟。哥哥性格活泼，喜欢交际，经常参加村里的各种活动，而弟弟则沉默寡言，总是埋头苦干。哥哥认为弟弟太死板，不懂得享受生活，而弟弟则觉得哥哥过于浮躁，缺乏耐心。有一天，村里要修建一座水坝，需要大量的人力物力。哥哥因为人缘好，很快召集到了一批人手，但因为缺乏周密的计划，进度缓慢，经常出现各种问题。弟弟则独自一人，默默地搬运石头，仔细地砌筑坝体。他每天工作到深夜，即使遇到困难，也不放弃，始终保持着一种认真专注的态度。经过几个月的努力，哥哥带领的队伍只完成了一小部分工程，而弟弟却已经完成了自己负责的那一部分，而且质量非常好。村里的人们都称赞弟弟的埋头苦干，并意识到只有踏实肯干才能成就一番事业。这个故事告诉我们，埋头苦干是成功的基石，只有专注于自己的目标，才能最终取得成功。
Long ago, in a remote mountain village, lived two hardworking brothers. The elder brother was outgoing and sociable, often participating in various village activities, while the younger brother was quiet and always worked hard. The elder brother thought his younger brother was too rigid and didn't know how to enjoy life, while the younger brother thought his elder brother was too impetuous and lacked patience. One day, the village needed to build a dam, which required a lot of manpower and material resources. Because of his good relationships, the elder brother quickly gathered a team of people, but due to a lack of careful planning, the progress was slow, and various problems frequently arose. The younger brother, on the other hand, worked alone, silently carrying stones and carefully building the dam. He worked every day until late at night, and even when faced with difficulties, he did not give up, always maintaining a serious and focused attitude. After several months of hard work, the elder brother's team had only completed a small part of the project, while the younger brother had already completed his part, and the quality was excellent. The villagers praised the younger brother's hard work and realized that only those who are down-to-earth and willing to work hard can achieve success. This story tells us that hard work is the cornerstone of success, and only by focusing on one's goals can one ultimately achieve success.
