Once the king of India fell ill and sent for his doctor. The doctor came, examined him and said, "You will be well again in a few days if you take bull’s (公牛的) milk." The king was very surprised, for he had never heard of a bull that gave milk. "How is it possible" he asked.
"Order Gulbo, the scholar, to get it for you. He can do anything." The doctor was an enemy to Gulbo, and thought this would be a way of him suffer. When the king told Gulbo what the doctor had said and ordered him to get bull’s milk, Gulbo immediately understood what the doctor was trying to do.
When he got home he sat thinking how to get out of the difficulties. His daughter, seeing him worried, asked what was the matter. On hearing what the king had asked for, she said, "Don’t worry, father. I’ll help you."
The next day she took some old clothes, went to the bank of the river near the palace, and chose a place below the king’s bedroom window. In the middle of the night, when everyone was in bed, she started to do her washing. She made so much noise that the king could not sleep. The king got very angry and sent a guard to find out what was the matter. The soldier found the girl, and led her to the king. "Why do you wash your clothes here at night" asked the king.
The girl pretended to be afraid and said, "I had to wash clothes at night. This afternoon my father had a baby. I was busy all day because of that. Then I found there were no clean clothes for the baby, so I had to come and wash them now."
"What!" cried the king, "Are you trying to make a fool of me Who ever heard of a man having a baby"
"Well, if the king himself orders someone to get bull’s milk for him, why can’t a man have a baby"
The king smiled and said, "You must be Gulbo’s daughter. Go and tell your father that he may keep the bull’s milk for his baby.\
