Manager Cheng said, "Ten thousand porcelain bottles and ten thousand pottery bottles, can we possibly get one-tenth of the goods ready within three days if we hurry back?"
Yuanzi Pharmacy had substantial resources, opening the conversation with an order of twenty thousand bottles of tooth powder.
Gu Jinli did some mental calculations and replied, "Yes."
One-tenth meant two thousand bottles, two hundred catties of tooth powder; their pharmaceutical workshop was fully equipped, and they had already hired fifty workers. They could grind out two hundred catties of tooth powder in one day, she could spend another day preparing it, and on the third day, they would be ready to deliver the goods.
Manager Cheng quickly wrote two contracts, one for Yuanzi Pharmacy with Xuanhu Fang, and another for Xuanhu Fang with the Gu Family pharmaceutical workshop.
