In the mid-Tang Dynasty, eunuchs had exclusive power, vassal towns were divided, and thousands of horses in the court were in silence. Liu Fan, a poor scholar from Youzhou, broke into Chang'an with a plan to break into Chang'an. During the palace examination, he pointed his sword at Beisi and bluntly said that "the temple has the right to abolish and establish." His policy comments shocked the government and the public, but he was deposed and was exiled throughout his life. From Youyan to Lingnan, my bones are unbreakable and my soul is immortal. This is a person's lonely courage against the silence of an era. Even if there is no light in the long night, he still has to make that long cry that breaks the silence.
