Chương 512: Chapter 512: Sun Junyan's Idea

Seeing Zhang Family and Tong Tiehu were suddenly stunned, especially Zhang Family, their face was as ghastly as if they had eaten a dead rat.

Sun Family couldn't help but feel smug.

Of course, this trick wasn't her own creation, it was taught to her by Sun Junyan.

Sun Junyan had once calculated for her. If as the Zhang Family stated, one pound of soybeans could only yield four pounds of bean sprouts, then in the past, when Qiao Xiaomai sold two pounds for one coin, four pounds would only earn two coins. But the cost of soybeans was three coins per pound. So, by this calculation, Qiao Xiaomai would suffer a loss of one coin.

In addition to the potential cost of other ingredients and labor, if one pound of soybeans really only produced four pounds of bean sprouts, Qiao Xiaomai would suffer a great loss.

Would such a smart person as Qiao Xiaomai agree to do business at a loss?
