Origin Story
话说唐朝时期，有个名叫李白的诗人，才华横溢，诗作名扬天下。一次，他来到长安，受到皇室的召见。李白初入宫廷，面对皇室的诸多文武大臣，竟是傲慢自大，目中无人。他旁若无人地高谈阔论，炫耀自己的才华，言语之间尽是轻蔑之词，甚至对一些资历比他老的官员也是不屑一顾。他的狂妄自大，让许多人感到不满，也让皇帝颇为不悦。后来，李白因得罪权贵，被贬官，流放各地，最终客死他乡。他的遭遇，正是狂妄自大的恶果。
It is said that during the Tang Dynasty, there was a poet named Li Bai who had extraordinary talents and whose poems were famous throughout the country. Once, he came to Chang'an and was summoned by the imperial family. When Li Bai first entered the court, he was arrogant and contemptuous of the many officials and ministers of the imperial court. He spoke loudly and boasted of his talents, despising others and even treating some officials with more experience than himself with disdain. His arrogance and conceit angered many, and even the emperor was displeased. Later, Li Bai was dismissed from his post due to offending powerful people and was sent into exile. Eventually, he died far from his hometown. His fate is a stark example of the negative consequences of arrogance and conceit.
