蜀贾卖药蜀贾三人皆卖药于市。其一人专取良,计入以为出,不虚价,亦不过取赢。一人良不良皆取焉,其价之贱贵,唯买者之欲,而随以其良、不良应之。一人不取良,唯其多,卖者贱其价,请益则益之,不较。于是争趋之,其门之限月一易。岁余而大富。其兼取者趋稍缓,再期亦富。其专取良者肆日中如宵,旦食而昏不足。明·刘基《郁离子·千里马篇》 The three companies selling medicines are selling drugs to the city. One of them is good enough to take it for granted. It does not cost or win. One person is all bad, and its price is high. Only the desire of the buyer, and its good, bad should be. One person does not take good, but as many as the seller sells for its price, and the benefit is better. As a result, the limit of the month is easy. Years old and rich. Its adopters tend to be slightly slower and richer again. His special merits are as good as those in the middle of the day. Ming Liu Ji “Yu-Ion Chili Ma”
