Eldest Son Xiao's wife, Mdm Wang, and Third Son Xiao's wife, Mdm Wu, glanced at each other and walked quickly to the entrance of their courtyard.
Then, they heard someone ask, "Dalang's wife, do you want to sell this tofu to other villages too?"
Shi Qingluo smiled and said, "We have to make and sell them. Our family doesn't have the energy to do so.
"So, if anyone has any ideas, you can buy it from us and then sell it in town or to other villages.
"If you can buy three catties of tofu from us in one go, you can exchange soybeans weighing eight taels for one catty, or four wen for one catty.
"But if it's more than three catties, you can only exchange it with soybeans or money.
"You can't exchange with anything else.
"You can sell it for five or six wen per catty, but it can't be higher than this price.
"Otherwise, I won't sell my tofu to those who deliberately sell them higher than six wen."
