The two sisters had always thought An Yi had great vision, so in the end they settled on a number: they didn't want chickens or eggs, they wanted only coarse grains.
Ten jin of soybeans could produce about five or six jin of tofu skin; ten jin of tofu skin was roughly twenty jin of soybeans, so what she gave...
"Ten jin of tofu skin, I'll count it as thirty jin of coarse grains for you—ten jin of potato, ten jin of sweet potato, how about it?"
This price was definitely a friendship price. The sisters looked at An Yi gratefully. "Sis, you really don't have to look after us like this."
"Isn't looking after you something I should do? Okay, since you have no objections, it's settled. Do you still have beans?"
"Yes, yes. Before the New Year we traded for quite a lot. In the village they're all trading for tofu now, everyone pays with money, so we can keep up with the amount you want."
