There was a village, the people in the village were rich(富有). They had beautiful houses and clothes. They were rich because they were good at business (生意). They bought things and sold things.
One day, a young man came to the village. He went to the market and talked with a businessman(商人). "Look," he said, "the people in your village are all rich. You are all good businessmen. Why?" "Why?" answered the businessman, "That is because we eat many fish, and the fish is very good for your brain (大脑). It makes us clever. ""I see, "said the young man, "and what is the name of the fish?" The businessman said" I'm sorry, I can't tell you. But if you give me ten dollars, I can give you some fish. "The young man thought this was a good idea. He gave the businessman ten dollars and the businessman gave him some fish.
After about a month, the young man visited the businessman again. "Thank you for your fish. "he said. "It's nothing." answered the businessman. "But listen, "said the young man, "three fish are not much for ten dollars!" The businessman smiled and said" Ah, yes. You see, the fish is beginning to work (起作用)!"
