Origin Story
话说唐朝时期，有个名叫李白的诗人，他非常有才华，但性格桀骜不驯，经常口出狂言，得罪了不少达官贵人。一次，他参加宫廷宴会，皇帝问他有何感想，李白不假思索地说：‘天子呼来不上船，自称臣是酒中仙。’此话一出，满座皆惊。大臣们都认为李白狂妄自大，冒犯了龙颜，纷纷指责他。但李白却毫不在意，依然我行我素。他那不畏权贵的傲骨和惊世骇俗的才华，令人叹为观止。虽然李白冒大不韪，但也赢得了人们的尊重。
In the Tang Dynasty, there was a poet named Li Bai. He was incredibly talented but also unruly and often offended dignitaries with his outspokenness. Once at a court banquet, the emperor asked him his thoughts. Li Bai, without hesitation, said, 'The emperor summons, but I don't board the ship; I call myself a celestial being in wine.' This caused a stir. Ministers considered Li Bai arrogant and disrespectful, criticizing him fiercely. But Li Bai remained unconcerned, true to his nature. His defiance of authority and his extraordinary talent inspired awe. Although Li Bai defied the norms, he gained the respect of the people.
