     There once lived in China a very foolish king and queen. One day the queen had a baby daughter.

When they saw their baby, they both cried out, "My goodness! How small it is! It's hairless and

toothless! It's a monster!" They sent for all the doctors in the country and ordered them to prepare some

medicine for her.

     "When she drinks your medicine, she must grow to the right size and have hair and teeth," the king

said, "If you don't do this, you'll have a beating."

     The doctors thought it impossible, but they dared not say anything against the king's order. Just then

and old doctor stepped forward. "Oh, we shall certainly obey your order," he said, "but it takes time.

We have to dig a mineral from the KunLun Mountains when the snow melts for the second time. The

snow melts on those mountains only once in six years. So we need twelve years."

     At last the king agreed and the doctors took away the little princess. On her twelfth birthday, they

brought her back to her parents with long black hair and beautiful teeth. The king and queen were very

happy and gave the doctors expensive presents.
