Villagers in Gracetown paid a hefty price for a secret insomnia cure, only to receive a bundle of ancient math texts three days later! The shipment included Zhou Bi Calculation, Nine Chapters on the Mathematical Art, Sunzi's Arithmetical Classic, Wucao Calculation, Xiahou Yang Calculation, Zhang Qiujian Calculation, and several other classical works. Furious at being duped, the villagers have filed a complaint with Kaifeng Prefecture.
