Upon hearing that, Shopkeeper He concealed his disappointment and asked, "How do you plan to sell this tofu?"
"Six wen per catty." Qiao Xiaomai stated the number she had already planned in her mind.
A catty of soybeans is three wen, which can make about three catties of tofu. Three catties of tofu costs eighteen wen. Aside from the cost of soybeans and firewood, vinegar, and labor, Qiao Xiaomai believed that her quoted price was very fair.
"This price is a bit high. A serving of stir-fried bean jelly only cost five wen." He Zhanggui lost his smile and took on a serious posture. He then took out his abacus to calculate for Qiao Xiaomai, "A catty of live chicken only costs seven or eight wen, and your tofu is almost the same price as meat. If I have to fry it or make a soup, plus the cost of various seasonings and labor, a plate of tofu alone will have to be sold for at least twelve wen."
