有人说,这世界上卖豆子的人应该是最快乐的,因为他们永远不必担心豆子卖不出去。卖豆人在豆子卖不出去的时候,可以拿回家,磨成豆浆,向人兜售;如果豆浆卖不成功,可以制成豆腐;豆腐卖不成功,变硬了,姑且当作豆腐干来卖;而豆腐干卖不出去的话,就把豆腐干腌起来,变成豆腐乳。 Some people say that people who sell beans in the world should be happiest because they never have to worry about beans not being sold. When a bean seller can’t sell the bean, he can take it home and grind it into milk and sell it to people. If the milk is not sold successfully, it can be made into bean curd; if tofu fails to sell, it becomes hard, and it is used as a tofu. If the dried bean curd does not sell, it will be dried and dried and become fermented bean curd.
