"Tears at the Tomb" tells the story of a dusty imperial examination injustice case in Qinghe County during the Ming Dynasty. Woodcutter Li Si accidentally unearthed dozens of failed examination papers buried in Xishan. Each paper had "It's a pity" and "It's so painful" annotated by academic Zhou Wenyuan. When the criticisms are circulated in the market and copied into books, the shady story of twenty years ago is gradually torn apart - the corruption of the powerful, the martyrdom of the scholars, and the struggle of conscience. All those involved will face the ultimate judgment of fate and conscience.
