Origin Story
话说唐朝贞观年间，长安城里发生了一件轰动全国的大案。吏部尚书李靖的独子李承乾，竟然参与了谋反。虽然他事先安排周密，但纸终究包不住火，他的反叛计划最终还是被皇帝得知，并且迅速平息。然而，他做的那些事，却在长安城里，乃至全国范围传得沸沸扬扬。虽然李承乾想尽办法掩盖自己的罪行，但事实真相却众目昭彰，人尽皆知。最终，李承乾被废为庶民，并被流放岭南。这起事件，也给后世留下了一个深刻的教训：任何阴谋诡计都逃不过正义的审判，而真相总是会浮出水面。
During the reign of Emperor Taizong in the Tang Dynasty, a sensational case occurred in Chang'an, the capital city. Li Chengqian, the only son of the Minister of Personnel, Li Jing, was involved in a rebellion. Though he made careful preparations beforehand, paper couldn't contain fire, and his rebellious plan was eventually discovered and quickly quelled by the emperor. However, his deeds became widely known throughout Chang'an and even the whole nation. Although Li Chengqian tried various means to cover up his crimes, the truth was evident to everyone. Eventually, Li Chengqian was reduced to a commoner and exiled to Lingnan. This incident served as a profound lesson for later generations: no conspiracy or trickery can escape the judgment of justice, and the truth always comes to light.
