Origin Story
话说唐朝时期，有个叫李白的诗人，他从小就喜欢读书，尤其对历史故事很感兴趣。有一天，他读到一本讲述三国时期诸葛亮的故事的书，书中详细描述了诸葛亮从草庐三顾到最终北伐的故事，从他未出茅庐就已知天下三分到最后五丈原病逝，每一个细节都交代得十分清楚，李白看得津津有味。他读完之后，不仅对诸葛亮的智慧和谋略叹服，更对历史事件的前因后果有了更深刻的理解。他感慨道：‘历史就像一幅巨大的画卷，每一个事件都有其前因后果，只有了解了前因后果，才能读懂历史的奥秘。’从此以后，李白更加注重观察和思考，在创作诗歌时，也善于从前因后果的角度去展开叙述，写出了许多脍炙人口的佳作。
It is said that during the Tang Dynasty, there was a poet named Li Bai, who loved reading since childhood, especially historical stories. One day, he read a book about Zhuge Liang during the Three Kingdoms period. The book detailed Zhuge Liang's story from the Three Visits to the Straw Hut to the final Northern Expedition, from his knowledge of the three-way division of the world before leaving his hut to his final death at Wuzhang Plain; every detail was explained very clearly. Li Bai read with great interest. After he finished reading, he was not only impressed by Zhuge Liang's wisdom and strategy but also had a deeper understanding of the causes and effects of historical events. He sighed: 'History is like a huge painting, each event has its causes and effects. Only by understanding the causes and effects can you understand the mysteries of history.' From then on, Li Bai paid more attention to observation and thought, and when he created poems, he was also good at unfolding the narrative from the perspective of cause and effect, writing many popular masterpieces.
