Third Grandpa said, "During the New Year it snowed heavily, somewhat alleviating the drought. Recently, the prices of rice, flour, and cotton have all been falling, so why are the soybeans suddenly going up?"
Gu Jinli, understanding the situation, said to Manager Tao, "Shopkeeper, the farmers sell their soybeans to your grain shop, and the highest price is only five cents for two pounds. When it's cheap, it's even one cent per pound or three cents for two pounds. You are asking five cents per pound from us, which is truly an exorbitant price, and that's not how you should raise prices."
She laughed, her laughter laced with disdain, and said: "Could it be that you see us buying soybeans here every day, and since this town only has your grain shop, you want to take a bite out of us?"
It's certain that seeing them buy soybeans every day, he figured out that tofu is made from soybeans, and seeing their tofu business thrive, he decided to raise the prices.
