The poor man was very happy. He gave it to the King (国王). The King was so glad that he gave the man a lot of money for it.
When a rich man heard of it, he said to himself, “It was only an orange. Why did the King give so much money for him? I would take my gold (金的) cup to the King. He would give me more money.”
